The company serves over 6,000 clients in 58 countries and in all major industry verticals. Dimension Data serves 79% of the Global Fortune Top 100 and 63% of the Global Fortune 500. Challenge In an effort to bring greater efficiency and flexibility, Dimension Data Australia sought to apply security industry best practices and streamlined processes to its delivery methodology. Automation was identified as a key capability that would enable them to reduce service costs and increase quality of service. “The operational management of security infrastructure is quite labor intensive,” remarks Martin Schlatter, Security Services Product Manager at Dimension Data. “The principle reasons for automating managed services are reducing work time, freeing up people for other tasks, and leveraging expertise that is ‘built in’ the automated tool.” By doing this Dimension Data could offer better service to existing clients while expanding their client base. “Additionally, the increased appetite for the Managed Security Services offering has been fueled by an increasing focus on governance, risk management and compliance, and we are expected to deliver faster and more accurate visibility of the security and compliance posture of the network,” explains Schlatter. Solution Dimension Data selected the AlgoSec Security Management Solution as a part of their toolset to deliver their Managed Security Services, which include automated and fully integrated operational management of client security infrastructures. The intelligent automation at the heart of AlgoSec will enable Dimension Data’s team to easily and effectively perform change monitoring, risk assessment, compliance verification and policy optimization for their clients, and act upon the findings quickly. This includes getting rid of unused or obsolete rules in the policy, reordering rules to increase performance and identifying risky rules. Another key factor in the decision making process was the relationship between Dimension Data and AlgoSec. “AlgoSec was deemed most suitable to meet our delivery needs for Managed Services. We selected them for their specific technology fit, and flexibility to assist in growing our managed service business. The partnership element was eventually the overriding factor,” says Schlatter. Results With AlgoSec, Dimension Data is now able to deliver their clients a comprehensive view of the security posture of their network security devices. This is crucial to establishing a baseline understanding of a security network, which makes it possible to truly assess and remediate risks, errors and inefficiencies. The ability to automatically provide this type of information at the most accurate level provides a key competitive differentiator for the company and a large benefit for its clients. “The value-added contribution is saving time, in terms of automation,” remarked Schlatter. “We found a way to reduce costs by automating manual operational tasks. At the same time, we were fortunate enough to leverage AlgoSec to expand our service offerings, so we got a double benefit from using AlgoSec in our environment.” One of the major features of integrating AlgoSec into the Dimension Data solution is the ability to support multiple client domains from a single AlgoSec management console. “This scalable configuration has proven to be invaluable when managing multiple clients with complex multi-vendor, multi-device security environments,” says Schlatter. “It consolidates administrative tasks, cuts time and costs, and ensures proper administration and segregation of duties from our end.” AlgoSec enhances the Managed Security Services offerings by delivering comprehensive risk and compliance management. Dimension Data professionals can generate risk and audit-ready compliance reports in a fraction of the time and with much greater accuracy compared to traditional manual analysis. “Our clients who require ISO 27001 and PCI DSS accreditation have greatly benefitted from this,” said Schlatter.

Learn about firewall rule automation and change management to streamline processes, reduce human error, and enhance network security with effective change controls. Firewall rule automation & change management explained Overview In today’s IT environment, the only constant is change. Not only is change rampant, but it often occurs at breakneck speed. Rapid business growth from mergers and acquisitions, development of new and de-commissioning of old applications, new users, micro-segmentation, cloud migrations and more make for a dynamic environment that poses new security challenges all the time. Schedule a Demo Introduction In today’s IT environment, the only constant is change. Not only is change rampant, but it often occurs at breakneck speed. For a variety of reasons – rapid business growth from mergers and acquisitions, development of new applications, de-commissioning of old applications, new users, evolving networks and evolving cyberthreats – business needs change and, as they do, so must security policies. But change comes with challenges, often leading to major headaches for IT operations and security teams. The headaches sometimes develop into huge business problems: Manual workflows and change management processes are time-consuming and impede IT from keeping up with the necessary business agility Improper management of even minor changes can lead to serious business risks as benign as blockage of legitimate traffic all the way to putting the entire network offline Some organizations have grown so wary of change control and its potential negative impact that they resort to network freezes during peak business times rather than attempt to implement an urgent change in their network security policies. AlgoSec has another point of view. We want to help you embrace change through process improvement, identifying areas where automation and actionable intelligence can simultaneously enhance security and business agility – without the headaches. Herein, you will learn the secrets of how to elevate your firewall change management from manual labor-intensive work to a fully automated change management process. Schedule a Demo Why is it so hard to make changes to network policies? Placing a sticky note on your firewall administrator’s desk and expecting the change request to be performed pronto does not constitute a formal policy. Yet, shockingly, this is common practice. A formal change request process is in order. Such a process dictates clearly defined and documented steps for how a change request is to be handled, by whom, how it is addressed within a specified SLA, and more. Using IT ticketing systems Popular IT ticketing systems, like ServiceNow and Remedy, are a good place to manage your firewall change requests. However, these system are built for tracking general requests and were never designed for handling complex requests such as opening the network flow from server A to server B or revising user groups. Informal change processes Having a policy state “this is what we must do” is a start, but without a formal set of steps for carrying out and enforcing that policy, you still have a long way to go in terms of smoothing out your change processes. In fact, the majority of challenges for managing network security devices include: Time-consuming manual processes Poor change-management processes Error-prone processes Firewall change management requires detailed and concise steps that everyone understands and follows. Exceptions must be approved and documented, continuously improving the process over time. Communication breakdown Network security and operations staff work in separate silos. Their goals, and even their languages, are different. Working in silos is a clear recipe for trouble. It is a major contributor to out-of-band (unexpected) changes which are notorious for resulting in “out-of-service.” In many large companies, routine IT operational and administrative tasks may be handled by a team other than the one that handles security and risk-related tasks. Although both teams work toward the same goal – smooth operation of the digital side of the business – decisions and actions made by one team may lead to problems for the other. Sometimes, these situations are alleviated in a rush with the good intention of dealing with security issues “later.” But this crucial “later” never arrives and the network remains open to breaches. In fact, according to a large-scale survey of our own customers, out-of-process firewall changes resulted in system outages for a majority of them. In addition, our customers pointed out that out-of-process changes have caused them exposure to data breaches and costly audit failures. How will you know if it’s broken? It’s imperative to know what the business is up against from the perspective of threats and vulnerabilities. What’s often overlooked, however, is the no-less-devastating impact of poorly managed firewall changes. Without carefully analyzing how even the most minor firewall changes are going to impact the network environment, businesses can suffer dramatic problems. Without thoughtful analysis, they might not know: What does the change do to vital visibility across the network? Which applications and connections are broken by this change? Which new security vulnerabilities are introduced? How will performance be affected? A lot of money and effort is put into keeping the bad guys out, while forgetting that “we have seen the enemy and he is us.” Network complexity is a security killer Renowned security expert, Bruce Schneier, has stated, “Complexity is the worst enemy of security.” The sheer complexity of any given network can lead to a lot of mistakes, especially when it comes to multiple firewalls with complex rule sets. Simplifying the firewall environment and management processes is necessary for good management. Did you know? Up to 30 percent of implemented rule changes in large firewall infrastructures are unnecessary because the firewalls are already allowing the requested traffic! Under time pressure, firewall administrators often create more rules which turn out to be redundant given already-existing rules. This wastes valuable time and makes the firewalls even harder to manage. Schedule a Demo Mind the gap? Not if you want a good change management process The introduction of new things opens up security gaps. New hires, software patches, upgrades and network updates all increase risk exposure. The situation is further complicated in larger organizations which may have a mixed security estate comprising traditional, next-generation and virtualized firewalls from multiple vendors across clouds and on-premise data centers, all with hundreds of policies and thousands of rules. Who can keep track of it all? What about unexpected, quick-fixes that enable access to certain resources or capabilities? In many cases, a fix is made in a rush (after all, who wants a C-level exec breathing down their neck because he wants to access the network from his new tablet RIGHT NOW?) without sufficient consideration of whether that change is allowable under current security policies, or if it introduces new exposures. Sure, you can’t predict when users will make change requests, but you can certainly prepare the process for handling these requests whenever they arise. Bringing both IT operations and security teams together to prepare game plans for these situations – and for other ‘knowns’ such as network upgrades, change freezes, and audits – helps to minimize the risk of security gaps. What’s more, there are solutions that automate day-to-day firewall management tasks and link these changes and procedures so that they are recorded as part of the change management plan. In fact, automated technologies can help bridge the gap between change management processes and what’s really taking place. They enhance accuracy, by removing people from the equation to a very large degree. For example, a sophisticated firewall and topology-aware workflow system that is able to identify redundant and unneeded change requests can increase the productivity of the IT staff. IT operations and security groups are ultimately responsible for making sure that systems are functioning properly so that business goals are continuously met. However, these teams approach business continuity from different perspectives. The security department’s number one goal is to protect the business and its data whereas the IT operations team is focused on keeping systems up and running. It is natural for these two teams to clash. However, oftentimes, IT operations and security teams align their perspectives because both have a crucial ownership stake. The business has to keep running AND it has to be secure. But this kind of alignment of interests is easier said than done. To achieve the alignment, organizations must re- examine current IT and security processes. Let’s have a look at some examples of what happens when alignment is not performed. Schedule a Demo Real-life examples of good changes gone bad Example 1 A classic lack of communication between the IT operations and security groups put XYZ Corporation at risk. An IT department administrator, who was trying to be helpful, took the initiative to set up (on his own, with no security involvement or documentation) an FTP share for a user who needed to upload files in a hurry. By making this off-the-cuff change, the IT admin quickly addressed the client’s request and the files were uploaded. However, the FTP account lingered unsecured well beyond its effective “use by” date. By the next day, the security team noticed larger spikes of inbound traffic to the server from this very FTP account. Hackers abound. The FTP site had been compromised and was being exploited to host pirated movies. Example 2 A core provider of e-commerce services to businesses in the U.S. suffered a horrible fate due to a simple, but poorly managed, firewall change. One day, all e-commerce transactions in and out of its network ceased and the entire business was taken offline for several hours. The costs were astronomical. What happened? An out-of-band (and untested) change to a core firewall broke the communication between the e-commerce application and the internet. Business activity ground to a halt. Executive management got involved and the responsible IT staff members were reprimanded. Hundreds of thousands of dollars later, the root cause of the outage was uncovered: IT staff, oblivious to the consequences, chose not to test their firewall changes, bypassing their “burdensome” ITIL-based change management procedures. Tips from your own peers Taken from The Big Collection of Firewall Management Tips Document, document, document … And when in doubt, document some more! “It is especially critical for people to document the rules they add or change so that other administrators know the purpose of each rule and whom to contact about it. Good documentation can make troubleshooting easy. It reduces the risk of service disruptions that inadvertently occur when an administrator deletes or changes a rule they do not understand.” – Todd, InfoSec Architect, United States “Keep a historical change log of your firewall policy so you can return to safe harbor in case something goes wrong. A proper change log should include the reason for the change, the requester and approval records.” – Pedro Cunha, Engineer, Oni, Portugal Schedule a Demo Taking the fire drill out of firewall changes Automation is the key. It helps staff disengage from firefighting and bouncing reactively between incidents. It helps them gain control. The right automation solution can help teams track down potential traffic or connectivity issues and highlight areas of risk. Administrators can get a handle on the current status of policy compliance across mixed estates of traditional, next-generation and virtualized firewalls as well as hybrid on-prem and cloud estates. The solution can also automatically pinpoint the devices that may require changes and show how to create and implement those changes in the most secure way. Automation not only makes firewall change management easier and more predictable across large estates and multiple teams, but also frees staff to handle more strategic security and compliance tasks. Let the solution handle the heavy lifting and free up the staff for other things. To ensure a proper balance between business continuity and security, look for a firewall policy management solution that: Measures every step of the change workflow so you can easily demonstrate that SLAs are being met Identifies potential bottlenecks and risks BEFORE changes are made Pinpoints change requests that require special attention Tips from your peers Taken from The Big Collection of Firewall Management Tips “Perform reconciliation between change requests and actual performed changes. Looking at the unaccounted changes will always surprise you. Ensuring every change is accounted for will greatly simplify your next audit and help in day-to-day troubleshooting.” – Ron, Manager, Australia “Have a workflow process for implementing a security rule from the user requesting change, through the approval process and implementation.” – Gordy, Senior Network Engineer, United States Schedule a Demo 10 steps to automating and standardizing the firewall change-management process Here is the secret to getting network security policy change management right. Once a request is made, a change-request process should include the following steps: Clarify the change request and determine the dependencies. Obtain all relevant information in the change request form (i.e., who is requesting the change and why). Get proper authorization for the change, matching it to specific devices and prioritizing it. Make sure you understand the dependencies and the impact on business applications, other devices and systems, etc. This usually involves multiple stakeholders from different teams. Validate that the change is necessary. AlgoSec research has found that up to 30% of changes are unnecessary. Weeding out redundant work can significantly improve IT operations and business agility. Perform a risk assessment. Before approving the change, thoroughly test it and analyze the results so as not to unintentionally open up the proverbial can of worms. Does the proposed change create a new risk in the security policy? You need to know this for certain BEFORE making the change. Plan the change. Assign resources, create and test your back-out plans, and schedule the change. Part of a good change plan involves having a backup plan in case a change goes unexpectedly wrong. This is also a good place in the process to ensure that everything is properly documented for troubleshooting or recertification purposes. Execute the change. Backup existing configurations, prepare target device(s) and notify appropriate workgroups of any planned outage and perform the actual change. Verify correct execution to avoid outages. Test the change, including affected systems and network traffic patterns. Audit and govern the change process. Review the executed change and any lessons learned. Having a non-operations-related group conduct the audit provides the necessary separation of duties and ensures a documented audit trail for every change. Measure SLAs. Establish new performance metrics and obtain a baseline measurement. Recertify policies. While not necessary for every rule change, part of your change management process should include a review and recertification of policies at an interval that you define (e.g., once a year). Oftentimes, rules are temporary – needed only for a certain period of time – but they are left in place beyond their active date. This step forces you to review why policies are in place, enabling you to improve documentation and to remove or tweak rules to align with the business. In some cases (e.g., data breach) a change to a firewall rule set must be made immediately, where, even with all the automation in the world, there is no time to go through the 10 steps. To address this type of situation, an emergency process should be defined and documented. Schedule a Demo Key capabiities to look for in a firewall change management solution Your workflow system must be firewall- and network-aware. This allows the system to gather the proper intelligence by pulling the configuration information from the firewalls to understand the current policies. Ultimately, this reduces the time it takes to complete many of the steps within the change process. In contrast, a general change management system will not have this integration and thus will provide no domain-specific expertise when it comes to making firewall rule changes. Your solution must support all of the firewalls and routers used within your organization. With the evolution of next-generation firewalls and new cloud devices, you should also consider how your plans fit into your firewall change-management decisions. In larger organizations, there are typically many firewalls from different vendors. If your solution cannot support all the devices in the environment (current and future), then this isn’t the solution for you! Your solution must be topology-aware. The solution must:Understand how the network is laid out Comprehend how the devices fit and interact Provide the necessary visibility of how traffic is flowing through the network Your solution must integrate with the existing general change management systems. This is important so that you can maximize the return on previously made investments. You don’t want to undergo a massive retraining on processes and systems simply because you have introduced a new solution. This integration allows users to continue using their familiar systems, but with the added intelligence from having that firewall-aware visibility and understanding that the new solution delivers. Your solution must provide out-of-the-box change workflows to streamline change-management processes as well as be highly customizable since no two organizations’ network and change processes are exactly the same. Key workflow capabilities to look for in a solution:Provide out-of-the-box change workflows to help you quickly tackle common change-request scenarios Offer the ability to tailor the change process to your unique business needs by: Creating request templates that define the information required to start a change process and pre-populate information where possible Enabling parallel approval steps within the workflow — ideal when multiple approvals are required to process a change Influencing the workflow according to dynamic information obtained during ticket processing (e.g., risk level, affected firewalls, urgency, ) Ensuring accountability and increasing corporate governance with logic that routes change requests to specific roles throughout the workflow Identify which firewalls and rules block requested traffic Detect and filter unneeded/redundant requests for traffic that is already permitted Provide “what-if” risk-analysis to ensure compliance with regulations and policies Automatically produce detailed work orders, indicating which new or existing rules to add or edit and which objects to create or reuse Prevent unauthorized changes by automatically matching detected policy changes with request tickets and reporting on mismatches Ensure that change requests have actually been implemented on the network, preventing premature closing of tickets Schedule a Demo Out-of-the-box workflow examples The best solutions allow for: Adding new rules via a wizard-driven request process and flow that includes impact analysis, change validation and audit Changing rules and objects by easily defining the requests for creation, modification and deletion, and identifying rules affected by suggested object modifications for best impact analysis Removing rules by automatically retrieving a list of change requests related to the rule-removal request, notifying all requestors of the impending change, managing the approval process, documenting and validating removal Recertifying rules by automatically presenting all tickets with deadlines to the responsible party for recertification or rejection and maintaining a full audit trail with actionable reporting Quantifying the ROI on firewall change-control automation Schedule a Demo Cut your costs Manual firewall change management is a time-consuming and error-prone process. Consider a typical change order that requires a total of four hours of work by several team members during the change lifecycle, including communication, validation, risk assessment, planning and design, execution, verification, documentation, auditing and measurement. Based on these assumptions, AlgoSec customers have reported significant cost savings (as much as 60%) achieved through: Reduction of 50% in processing time using automation Elimination of 30% of unnecessary changes Elimination of 8% of changes that are reopened due to incorrect implementation Schedule a Demo Summary While change management is complex stuff, the decision for your business is actually simple. You can continue to slowly chug along with manual change management processes that drain your IT resources and impede agility. Or you can accelerate your processes with an automated network change- management workflow solution that aligns the different stakeholders involved in the process (network operations, network security, compliance, business owners, etc.) and helps the business run more smoothly. Think of your change process as a key component of the engine of an expensive car (in this case, your organization). Would you drive your car at high speed if you didn’t have tested, dependable brakes or a steering wheel? Hopefully, the answer is no! The brakes and steering wheel are analogous to change controls and processes. Rather than slowing you down, they actually make you go faster, securely! Power steering and power brakes (in this case, firewall-aware integration and automation) help you zoom to success.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 9/29/21 Published Tsippi Dach, Director of Communications at AlgoSec, explores what happened during this past summer’s Fastly outage, and explores how your business can protect itself in the future. The odds are that before June 8th you probably hadn’t heard of Fastly unless you were a customer. It was only when swathes of the internet went down with the 503: Service Unavailable error message that the edge cloud provider started to make headlines . For almost an hour, sites like Amazon and eBay were inaccessible, costing millions of dollars’ worth of revenue. PayPal, which processed roughly $106 million worth of transactions per hour throughout 2020, was also impacted, and disruption at Shopify left thousands of online retail businesses unable to serve customers. While the true cost of losing a significant portion of the internet for almost one hour is yet to be tallied, we do know what caused it. What is Fastly and why did it break the internet? Fastly is a US-based content distribution network (CDN), sometimes referred to as an ‘edge cloud provider.’ CDNs relieve the load on a website’s servers and ostensibly improve performance for end-users by caching copies of web pages on a distributed network of servers that are geographically closer to them. The downside is that when a CDN goes down – due to a configuration error in Fastly’s case – it reveals just how vulnerable businesses are to forces outside of their control. Many websites, perhaps even yours, are heavily dependent on a handful of cloud-based providers. When these providers experience difficulties, the consequences for your business are amplified ten-fold. Not only do you run the risk of long-term and costly disruption, but these weak links can also provide a golden opportunity for bad actors to target your business with malicious software that can move laterally across your network and cause untold damage. How micro-segmentation can help The security and operational risks caused by these outages can be easily mitigated by implementing plans that should already be part of an organization’s cyber resilience strategy. One aspect of this is micro-segmentation , which is regarded as one of the most effective methods to limit the damage of an intrusion or attack and therefore limit large-scale downtime from configuration misfires and cyberattacks. Micro-segmentation is the act of creating secure “zones” in data centers and cloud deployments that allow your company to isolate workloads from one another. In effect, this makes your network security more compartmentalized, so that if a bad actor takes advantage of an outage in order to breach your organization’s network, or user error causes a system malfunction, you can isolate the incident and prevent lateral impact. Simplifying micro-segmentation with AlgoSec Security Management Suite The AlgoSec Security Management Suite employs the power of automation to make it easy for businesses to define and enforce their micro-segmentation strategy, ensuring that it does not block critical business services, and also meets compliance requirements. AlgoSec supports micro-segmentation by: Mapping the applications and traffic flows across your hybrid network Identifying unprotected network flows that do not cross any firewall and are not filtered for an application Automatically identifying changes that will violate the micro-segmentation strategy Ensuring easy management of network security policies across your hybrid network Automatically implementing network security policy changes Automatically validating changes Generating a custom report on compliance with the micro-segmentation policy Find out more about how micro-segmentation can help you boost your security posture, or request your personal demo .

Learn from expert-crafted firewall ruleset examples and best practices. Optimize your security posture with actionable guidance and improve your firewall configurations. Firewall ruleset examples & policy best practices Securing your network: guide to firewall rules examples Cyberattacks continue to rise globally as malicious actors tirelessly develop sophisticated tools and techniques to break through networks and security systems. With the digitalization of operations today and the increasing adoption of remote working, crucial business activities such as communication, data storage, and data transmission are now primarily done digitally. While this brings numerous advantages – allowing easy usability and scalability, enhancing collaboration, and reducing the risks of data loss – businesses have to deal with various security risks, such as data breaches and cyberattacks from hackers. Organizations must provide adequate network security to keep sensitive data safe and ensure their network is usable, trustworthy, and optimized for maximum productivity across all channels. Schedule a Demo Firewalls and your network Your network and systems (software and hardware) comprise the IT infrastructure through which you operate and manage your enterprise’s IT services. Every IT system regularly receives and transmits internet traffic, and businesses must ensure that only trusted and authorized traffic penetrates their network to maintain security. All unwanted traffic must be prevented from accessing your operating system as it poses a huge risk to network security. Malicious actors attempting to penetrate your system often send virus-carrying inbound traffic to your network. However, with an effective firewall, you can filter all traffic and block unwanted and harmful traffic from penetrating your network. A firewall serves as a barrier between computers, networks, and other systems in your IT landscape, preventing unauthorized traffic from penetrating. Schedule a Demo What are firewall rules? The firewall is your first line of defense in network security against hackers, malware, and other threats. Firewall rules refer to access control mechanisms that stipulate how a firewall device should handle incoming and outgoing traffic in your network. They are instructions given to firewalls to help them know when to block or allow communication in your network. These instructions include destination or source IP addresses, protocols, port numbers, and services. A firewall ruleset is formed from a set of rules and it defines a unit of execution and sharing for the rules. Firewall rulesets typically include: A source address A source port A destination address A destination port A decision on whether to block or permit network traffic meeting those address and port criteria Schedule a Demo What are the most common firewall ruleset examples? There are thousands of rulesets that can be used to control how a firewall deals with network traffic. Some firewall rules are more common than others, as they tend to be fundamental when building a secure network. Here are some examples of firewall rules for common use cases: Enable internet access for only one computer in the local network and block access for all others This rule gives only one computer in the local network access to the internet, and blocks all others from accessing the internet. This example requires obtaining the IP address of the computer being granted access (i.e., source IP address) and the TCP protocol type. Two rules will be created: a Permit rule and a Deny rule. The permit rule allows the chosen computer the required access, while the deny rule blocks all other computers in the local network from internet access. Prevent direct access from the public network to the firewall This rule blocks access to your firewall from any public network, to protect it from hackers who can modify or delete your rules if they access your firewall directly. Once hackers manipulate your rules, unwanted traffic will penetrate your network, leading to data breaches or an interruption in operation. A Deny rule for any attempt to access the firewall from public networks will be created and enabled. Block internet access for only one computer in the local network This rule comes in handy if you do not want a specific computer in the local network to access the internet. You will need to create a Deny rule in which you set the IP address of the computer you wish to block from the internet, and the TCP protocol type. Block access to a specific website from a local network In this scenario we want to configure our firewall to deny access to a particular website from a local network. We first obtain the IP address or addresses of the website we wish to deny access to, and then create a Deny rule. One way to obtain a website’s IP address is by running the special command ‘nslookup ’ in your operating system’s command line (Windows, Linux, or others). Since websites can run on HTTP and HTTPS, we must create a Deny rule for each protocol type and indicate the destination IP address(es). Thus, the local network will be unable to access both the HTTP and HTTPS versions of the website. Allow a particular LAN computer to access only one specific website This example gives a local computer access to only one specified website. We obtain the IP address of the destination website and the source IP address (of the local computer). We create a Permit rule for the source IP address and the destination website, and a Deny rule for the source IP address and other websites, taking the TCP protocol types into account. Allow internet access to and from the local network using specific protocols (services) only This example allows your LAN computer to access the internet using specific protocols, such as SMTP, FTP, IPv6, SSH, IPv4, POP3, DNS, and IMAP; and blocks all other traffic Here we first create an “Allow” rule for the “Home segment,” where we use the value “Any” for the Source and Destination IP addresses. In the Protocol field provided, we choose the protocols through which our local computer can access the internet. Lastly, we create Deny rules where we enter the value “Any” for the Source and Destination IP addresses. In the Protocol field, we set the values TCP and UDP, thus blocking internet access for unspecified protocols. Allow remote control of your router This rule enables you to access, view, or change your Router Settings remotely (over the internet). Typically, access to routers from the internet is blocked by default. To set this rule, you need specific data such as your router username, WAN IP address, and password. It is crucial to note that this setting is unsafe for individuals who use public IP addresses. A similar use case is a rule enabling users to check a device’s availability on their network by allowing ICMP ping requests. Block access from a defined internet subnet or an external network You can set a rule that blocks access to your network from a defined internet subnet or an external network. This rule is especially important if you observed repeated attempts to access your router from unknown IP addresses within the same subnet. In this case, set a Deny rule for IP addresses of the subnet attempting to access your WAN port. Schedule a Demo What are examples of best practices for setting up firewall rules? It is expedient to follow best practices during firewall configuration to protect your network from intruders and hackers. Deploying industry-standard rules when setting up firewalls can improve the security of your network and system components. Below are examples of the best practices for setting up firewall rules. Document firewall rules across multiple devices Documenting all firewall rule configurations and updating them frequently across various devices is one of the best practices for staying ahead of attacks. New rules should be included based on security needs, and irrelevant rules should be deactivated to reduce the possibility of a loophole in your network. With documentation, administrators can review the rules frequently and make any required changes whenever a vulnerability is detected. Configure your firewall to block traffic by default Using a block or deny-by-default policy is the safest way to deal with suspicious traffic. Enterprises must be sure that all types of traffic entering their network are identified and trusted to avoid security threats. In addition, whenever a vulnerability arises in the system, blocking by default helps prevent hackers from taking advantage of loopholes before administrators can respond. Monitor firewall logs Monitoring firewall logs on a regular basis helps maintain network security. Administrators can quickly and easily track traffic flow across your network, identify suspicious activity, and implement effective solutions in a timely manner. Organizations with highly sophisticated infrastructure can aggregate logs from routers, servers, switches, and other components to a centralized platform for monitoring. Group firewall rules to minimize complexity and enhance performance Depending on the complexity of your network, you may need thousands of rules to achieve effective network security. This complicates your firewall rules and can be a huge challenge for administrators. However, by grouping rules based on similar characteristics like protocols, TCP ports, IP addresses, etc., you simplify them and boost overall performance. Implement least-privileged access In any organization, employees have various roles and may require different data to execute their tasks efficiently. As part of network security practices, it’s important to ensure each employee’s access to the network is restricted to the minimum privileges needed to execute their tasks. Only users who require access to a particular service or resource should have it, thus preventing unnecessary exposure of data. This practice significantly minimizes the risk of intentional and accidental unauthorized access to sensitive data. Schedule a Demo How do firewall policies differ from a network security policy? A network security policy outlines the overall rules, principles, and procedures for maintaining security on a computer network. The policy sets out the basic architecture of an organization’s network security environment, including details of how the security policies are implemented. The overall objective of network security policy is to protect a computer network against internal and external threats. Firewall policies are a sub-group of network security policies, and refer to policies that relate specifically to firewalls. Firewall policies have to do with rules for how firewalls should handle inbound and outbound traffic to ensure that malicious actors do not penetrate the network. A firewall policy determines the types of traffic that should flow through your network based on your organization’s network and information security policies. Schedule a Demo How can AlgoSec help with managing your firewall rules? Proper firewall configuration with effective rules and practices is crucial to building a formidable network security policy. Organizations must follow industry standards in configuring firewall rules and protecting their IT landscape from intruders and malicious actors.

Tags Share this article 3/19/23 Published As organizations respond to an ever-evolving set of security threats, network teams are scrambling to find new ways to keep up with numerous standards and regulations to dodge their next compliance audit violation. Can this nightmare be avoided? Yes, and it’s not as complex as one might think if you take a “compliance first” approach . It may not come as a surprise to many, but the number of cyber attacks is increasing every year and with it the risk to companies’ financial, organizational, and reputational standing. What’s at stake? The stakes are high when it comes to cyber security compliance. A single data breach can result in massive financial losses, damage to a company’s reputation, and even jail time for executives. Data breaches: Data breaches are expensive and becoming even more so by the day. According to the Ponemon Institute’s 2022 Cost of a Data Breach Report , the average cost of a data breach is $4.35 million. Fraud: Identity fraud is one of the most pressing cybersecurity threats today. In large organizations, the scale of fraud is also usually large, resulting in huge losses causing depletion of profitability. In a recent survey done by PwC, nearly one in five organizations said that their most disruptive incident cost over $50 million*. Theft: Identity theft is on the rise and can be the first step towards compromising a business. According a study from Javelin Strategy & Research found that identity fraud costs US businesses an estimated total of $56 billion* in 2021. What’s the potential impact? The potential impact of non-compliance can be devastating to an organization. Financial penalties, loss of customers, and damage to reputation are just a few of the possible consequences. To avoid these risks, organizations must make compliance a priority and take steps to ensure that they are meeting all relevant requirements. Legal impact:  Regulatory or legal action brought against the organization or its employees that could result in fines, penalties, imprisonment, product seizures, or debarment.  Financial impact:  Negative impacts with regard to the organization’s bottom line, share price, potential future earnings, or loss of investor confidence.  Business impact:  Adverse events, such as embargos or plant shutdowns, could significantly disrupt the organization’s ability to operate.  Reputational impact:  Damage to the organization’s reputation or brand—for example, bad press or social-media discussion, loss of customer trust, or decreased employee morale.  How can this be avoided? In order to stay ahead of the ever-expanding regulatory requirements, organizations must adopt a “compliance first” approach to cyber security. This means enforcing strict compliance criteria and taking immediate action to address any violations to ensure data is protected. Some of these measures include the following: Risk assessment: Conduct ongoing monitoring of compliance posture (risk assessment) and conduct regular internal audits (ensuring adherence with regulatory and legislative requirements (HIPAA, GDPR, PCI DSS, SOX, etc.) Documentation: Enforce continuous tracking of changes and intent Annual audits: Commission 3rd party annual audits to ensure adherence with regulatory and legislative requirements (HIPAA, GDPR, PCI DSS, SOX, etc.) Conclusion and next steps Compliance violations are no laughing matter. They can result in fines, business loss, and even jail time in extreme cases. They can be difficult to avoid unless you take the right steps to avoid them. You have a complex set of rules and regulations to follow as well as numerous procedures, processes, and policies. And if you don’t stay on top of things, you can end up with a compliance violation mess that is difficult to untangle. Fortunately, there are ways to reduce the risk of being blindsided by a compliance violation mess with your organization. Now that you know the risks and what needs to be done, here are six best practices for achieving it.

Level Up Your Security Game: Time for a Mindset Reset! Hey everyone, and welcome! If you're involved in keeping your organization safe online these days, you're in the right place. For years, security felt like building a super strong castle with thick walls and a deep moat, hoping the bad guys would just stay outside. But let's be real, in our multi-cloud world, that castle is starting to look a little... outdated.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/9/25 Published Level Up Your Security Game: Time for a Mindset Reset! Hey everyone, and welcome! If you're involved in keeping your organization safe online these days, you're in the right place. For years, security felt like building a super strong castle with thick walls and a deep moat, hoping the bad guys would just stay outside. But let's be real, in our multi-cloud world, that castle is starting to look a little... outdated. Think about it: your apps and data aren't neatly tucked away in one place anymore. They're bouncing around on AWS, Azure, GCP, all sorts of platforms – practically everywhere! Trying to handle that with old-school security is like trying to catch smoke with a fishing net. Not gonna work, right? That's why we're chatting today. Gal Yosef, Head of Product Management in the U.S., gets it. He's helped us dive into some crucial mindset shifts – basically, new ways of thinking – that are essential for navigating the craziness of modern security. We gotta ditch the old ways and get ready to be more agile, work together better, and ultimately, be way more effective. Mindset Shift #1: From "Our Stuff is Safe Inside This Box" to "Trust Nothing, Verify Everything" Remember the good old days? We built a perimeter – firewalls, VPNs – thinking that everything inside was safe and sound (danger!). Security was all about guarding that edge. The Problem: Well, guess what? That world is gone! Multi-cloud environments have totally shattered that perimeter. Trying to just secure the network edge leaves your real treasures – your applications, users, and data – vulnerable as they roam across different clouds. It's like locking the front door but leaving all the windows wide open! The New Way: Distributed Trust. Security needs to follow your assets, wherever they go. Instead of just focusing on the infrastructure (the pipes and wires), we need to embrace Zero-Trust principles . Think of it like this: never assume anyone or anything is trustworthy, even if they're "inside." We need identity-based, adaptive security policies that constantly validate trust, rather than just assuming it based on location. Security becomes built into applications and workloads, not just bolted onto the network. Think of it this way: Instead of one big, guarded gate, you have individual, smart locks on every valuable asset. You're constantly checking who's accessing what, no matter where they are. It's like having a personal bodyguard for each of your important things, always making sure they have the right ID. Mindset Shift #2: From "My Team Handles Network Security, Their Team Handles Cloud Security" to "Let's All Be Security Buddies!" Ever feel like your network security team speaks a different language than your cloud security team? You're not alone! Traditionally, these have been separate worlds, with network teams focused on firewalls and cloud teams on security groups. The Problem: These separate silos are a recipe for confusion and fragmented security policies. Attackers? They love this! It's like having cracks in your armor. They aren't always going to bash down the front door; they're often slipping through the gaps created by this lack of communication. The New Way: Cross-functional collaboration. We need to tear down those walls! Network and cloud security teams need to work together, speaking a shared security language. Unified visibility and consistent policies across all your environments are key. Think of it like a superhero team – everyone has their own skills, but they work together seamlessly to fight the bad guys. Regular communication, shared tools, and a common understanding of the risks are crucial. Mindset Shift #3: From "Reacting When Something Breaks" to "Always Watching and Fixing Things Before They Do" Remember the old days of waiting for an alert to pop up saying something was wrong? That's like waiting for your car to break down before you even think about checking the oil. Not the smartest move, right? The Problem: In the fast-paced world of the cloud, waiting for things to go wrong is a recipe for disaster. Attacks can happen super quickly, and by the time you react, the damage might already be done. Plus, manually checking everything all the time? Forget about it – it's just not scalable when you've got stuff spread across multiple clouds. The New Way: Continuous & Automated Enforcement. We need to shift to a mindset of constant monitoring and automated security actions. Think of it like having a security system that's always on, always learning, and can automatically respond to threats in real-time. This means using tools and processes that continuously check for vulnerabilities, enforce security policies automatically, and even predict potential problems before they happen. It's like having a proactive security guard who not only watches for trouble but can also automatically lock doors and sound alarms the moment something looks fishy. Mindset Shift #4: From "Locking Everything Down Tight" to "Finding the Right Balance with Flexible Rules" We used to think the best security was the strictest security – lock everything down, say "no" to everything. But let's be honest, that can make it super hard for people to actually do their jobs! It's like putting so many locks on a door that nobody can actually get through it. The Problem: Overly restrictive security can stifle innovation and slow things down. Developers can get frustrated, and the business can't move as quickly as it needs to. Plus, sometimes those super strict rules can even create workarounds that actually make things less secure in the long run. The New Way: Flexible Guardrails. We need to move towards security that provides clear boundaries (the "guardrails") but also allows for agility and flexibility. Think of it like setting clear traffic laws – you know what's allowed and what's not, but you can still drive where you need to go. This means defining security policies that are adaptable to different cloud environments and business needs. It's about enabling secure innovation, not blocking it. We need to find that sweet spot where security empowers the business instead of hindering it. Mindset Shift #5: From "Security is a Cost Center" to "Security is a Business Enabler" Sometimes, security gets seen as just an expense, something we have to do but doesn't really add value. It's like thinking of insurance as just another bill. The Problem: When security is viewed as just a cost, it often gets underfunded or seen as a roadblock. This can lead to cutting corners and ultimately increasing risk. It's like trying to save money by neglecting the brakes on your car – it might seem cheaper in the short term, but it can have disastrous consequences later. The New Way: Security as a Business Enabler. We need to flip this thinking! Strong security isn't just about preventing bad things from happening; it's about building trust with customers, enabling new business opportunities, and ensuring the long-term resilience of the organization. Think of it like a strong foundation for a building – without it, you can't build anything lasting. By building security into our processes and products from the start, we can actually accelerate innovation and gain a competitive advantage. It's about showing our customers that we take their data seriously and that they can trust us. Wrapping Up: Moving to a multi-cloud world is exciting, but it definitely throws some curveballs at how we think about security. By adopting these five new mindsets, we can ditch the outdated castle mentality and build a more agile, collaborative, and ultimately more secure future for our organizations. It's not about being perfect overnight, but about starting to shift our thinking and embracing these new approaches. So, let's level up our security game together!

Tags Share this article 1/2/24 Published Jeremiah Cornelius, Technical Lead for Alliances and Partners at AlgoSec, discusses how Cisco Nexus Dashboard Orchestrator (NDO) users can achieve policy-driven application-centric security management with AlgoSec. Leading Edge of the Data Center with AlgoSec and Cisco NDO AlgoSec ASMS A32.6 is our latest release to feature a major technology integration, built upon our well-established collaboration with Cisco — bringing this partnership to the front of the Cisco innovation cycle with support for Nexus Dashboard Orchestrator (NDO) . NDO allows Cisco ACI – and legacy-style Data Center Network Management – to operate at scale in a global context, across data center and cloud regions. The AlgoSec solution with NDO brings the power of our intelligent automation and software-defined security features for ACI, including planning, change management, and microsegmentation, to this global scope. I urge you to see what AlgoSec delivers for ACI with multiple use cases, enabling application-mode operation and microsegmentation, and delivering integrated security operations workflows. AlgoSec now brings support for Shadow EPG and Inter-Site Contracts with NDO, to our existing ACI strength. Let’s Change the World by Intent I had my first encounter with Cisco Application Centric Infrastructure in 2014 at a Symantec Vision conference. The original Senior Product Manager and Technical Marketing lead were hosting a discussion about the new results from their recent Insieme acquisition and were eager to onboard new partners with security cases and added operations value. At the time I was promoting the security ecosystem of a different platform vendor, and I have to admit that I didn’t fully understand the tremendous changes that ACI was bringing to security for enterprise connectivity. It’s hard to believe that it’s now seven years since then and that Cisco ACI has mainstreamed software-defined networking — changing the way that network teams had grown used to running their networks and devices since at least the mid-’90s. Since that 2014 introduction, Cisco’s ACI changed the landscape of data center networking by introducing an intent-based approach, over earlier configuration-centric architecture models. This opened the way for accelerated movement by enterprise data centers to meet their requirements for internal cloud deployments, new DevOps and serverless application models, and the extension of these to public clouds for hybrid operation – all within a single networking technology that uses familiar switching elements. Two new, software-defined artifacts make this possible in ACI: End-Point Groups (EPG) and Contracts – individual rules that define characteristics and behavior for an allowed network connection. ACI Is Great, NDO Is Global That’s really where NDO comes into the picture. By now, we have an ACI-driven data center networking infrastructure, with management redundancy for the availability of applications and preserving their intent characteristics. Through the use of an infrastructure built on EPGs and contracts, we can reach from the mobile and desktop to the datacenter and the cloud. This means our next barrier is the sharing of intent-based objects and management operations, beyond the confines of a single data center. We want to do this without clustering types, that depend on the availability risk of individual controllers, and hit other limits for availability and oversight. Instead of labor-intensive and error-prone duplication of data center networks and security in different regions, and for different zones of cloud operation, NDO introduces “stretched” shadow EPGs, and inter-site contracts, for application-centric and intent-based, secure traffic which is agnostic to global topologies – wherever your users and applications need to be. NDO Deployment Topology – Image: Cisco Getting NDO Together with AlgoSec: Policy-Driven, App-Centric Security Management  Having added NDO capability to the formidable shared platform of AlgoSec and Cisco ACI, regional-wide and global policy operations can be executed in confidence with intelligent automation. AlgoSec makes it possible to plan for operations of the Cisco NDO scope of connected fabrics in application-centric mode, unlocking the ACI super-powers for micro-segmentation. This enables a shared model between networking and security teams for zero-trust and defense-in-depth, with accelerated, global-scope, secure application changes at the speed of business demand — within minutes, rather than days or weeks. Change management : For security policy change management this means that workloads may be securely re-located from on-premises to public cloud, under a single and uniform network model and change-management framework — ensuring consistency across multiple clouds and hybrid environments. Visibility : With an NDO-enabled ACI networking infrastructure and AlgoSec’s ASMS, all connectivity can be visualized at multiple levels of detail, across an entire multi-vendor, multi-cloud network. This means that individual security risks can be directly correlated to the assets that are impacted, and a full understanding of the impact by security controls on an application’s availability. Risk and Compliance : It’s possible across all the NDO connected fabrics to identify risk on-premises and through the connected ACI cloud networks, including additional cloud-provider security controls. The AlgoSec solution makes this a self-documenting system for NDO, with detailed reporting and an audit trail of network security changes, related to original business and application requests. This means that you can generate automated compliance reports, supporting a wide range of global regulations, and your own, self-tailored policies. The Road Ahead Cisco NDO is a major technology and AlgoSec is in the early days with our feature introduction, nonetheless, we are delighted and enthusiastic about our early adoption customers. Based on early reports with our Cisco partners, needs will arise for more automation, which would include the “zero-touch” push for policy changes – committing Shadow EPG and Inter-site Contract changes to the orchestrator, as we currently do for ACI APIC. Feedback will also shape a need for automation playbooks and workflows that are most useful in the NDO context, and that we can realize with a full committable policy by the ASMS Firewall Analyzer. Contact Us! I encourage anyone interested in NDO and enhancing their operational maturity in aligned network and security operation, to talk to us about our joint solution. We work together with Cisco teams and resellers and will be glad to share more.

Top 10 cloud security tips and best practices for 2025 Select a size Which network Can AlgoSec be used for continuous compliance monitoring? Yes, AlgoSec supports continuous compliance monitoring. As organizations adapt their security policies to meet emerging threats and address new vulnerabilities, they must constantly verify these changes against the compliance frameworks they subscribe to. AlgoSec can generate risk assessment reports and conduct internal audits on-demand, allowing compliance officers to monitor compliance performance in real-time. Security professionals can also use AlgoSec to preview and simulate proposed changes to the organization’s security policies. This gives compliance officers a valuable degree of lead-time before planned changes impact regulatory guidelines and allows for continuous real-time monitoring. Top 10 cloud security tips & best practices for 2025 This year’s cloud security recommendations look slightly different from previous years. There are two key reasons for this: New technologies like GenAI and agentic apps have emerged. Attackers are using more sophisticated techniques to exploit cloud assets and evade detection. For example, what used to be basic, easy-to-spot phishing has now become extensive vishing and deep-fake campaigns that even technical experts fall for. To stay ahead of 2025’s threats, the following cloud security best practices are essential. Quick review: What is cloud security and why are cloud security best practices important? Cloud security consists of the controls, policies, and technologies implemented for protecting cloud environments from threats. This includes data, services, applications, configurations, and GenAI models in the cloud. As access to technology has democratized how threat actors launch attacks, cloud security has taken on new meaning and is no longer solely about defense. With cutting-edge tools that often rival many organizations’ defenses at attackers’ disposal, proactive prevention is a must. 10 tips for cloud security Implementing the following recommendations will increase the security of your cloud assets and enhance your overall security posture. 1. Understand the shared responsibility model Traditionally, CSPs (e.g., AWS, Azure, GCP) handle securing your underlying cloud infrastructure and managed services. You, as the customer, need to secure everything running in the cloud (data, applications, configurations, etc.). However, with the arrival of GenAI, companies now also have to worry about safeguarding AI data and AI models. Tips: Understand and embrace your roles as specified by your provider. Establish explicit agreements with providers and supply chain vendors to ensure the integrity of third-party assets. Facilitate shared accountability. 2. Prioritize AI security New technologies come with unknown risks, and adopting them without proper safeguards is an invitation to attack. Tips: Use software composition analysis (SCA) to detect and block vulnerable AI packages to eliminate backdoors that hackers could exploit to attack your cloud environment. Protect your AI training data, model tuning pipelines, and inference endpoints with encryption, strict access controls, and AI-specific guardrails (e.g., model drift detection). Verify provider-enforced tenant isolation to safeguard your AI workloads from multi-tenant risks like data leakage and unauthorized access. Continuously monitor model behavior to spot common AI risks such as model poisoning and compromised AI APIs. Implement input/output validation using dedicated filtering tools (e.g., NVIDIA NeMo Guardrails) to block prompt injection, data exfiltration, and similar attacks. 3. Adopt shift-left security Shift-left security is the practice of securing cloud-native applications and APIs from the development phase. This dramatically reduces your threat footprint and remediation costs. Tips: Embrace secure coding ; integrate automated security and compliance checks (triggered at every pull request or commit) into the CI pipeline; this instantly flags and resolves vulnerable or non-compliant code before it goes live. Use secure container images from trusted sources; scanning for vulnerabilities enhances runtime security and minimizes potential attacker entry points. Store secrets securely (e.g., in HashiCorp Vault) and embed secret detection into developer workflows to uncover hardcoded secrets; this prevents threat actors from gaining a foothold in your cloud environment via exposed secrets. Shield-right as you shift-left, e.g., by enforcing real-time monitoring to detect any blind spots early; this helps deter hackers, who thrive on missed vulnerabilities. 4. Manage identity and access with least privilege and zero trust Embrace centralized identity and access management (IAM), defining policies that govern who can access what. Tips: Implement least privilege (e.g., via RBAC and ABAC), ensuring only essential human and machine identities can access cloud and AI workloads. Adopt a zero trust architecture, segmenting workloads and continuously verifying access rights with MFA, within and outside your network perimeter. Regularly review access rights to revoke unnecessary permissions. 5. Harden configurations Cloud assets, AI workloads, networks, and identities are all pretty easy to misconfigure—making them top causes of breaches. Tips: Validate IaC templates to eliminate security risks before code is shipped. Continuously assess cloud configurations to resolve publicly exposed assets fast. Autonomously enforce security policies with PaC for consistent security and compliance across hybrid and multi-cloud workloads. Enforce timely patching with automated patch management tools to fix vulnerabilities before they become attack vectors. Regularly audit firewall rules to spot misconfigurations that could compromise your cloud resources and networks. 6. Address shadow IT Shadow IT elements (e.g., unsanctioned VMs, data, APIs, and GPUs) are top security risks because they evade centralized governance and monitoring. Tips: Establish policies that balance security with productivity to eliminate the need to bypass centralized security. Automatically block unauthorized deployments from the source, using policies that require resources to be provisioned solely through approved templates. Continuously monitor data flows to discover and resolve shadow IT. 7. Embrace real-time monitoring, detection, and response Continuous monitoring spots threats and anomalies, such as unusual login patterns or configuration changes, before full-blown attacks occur. Tips: Track user behavior in real time to spot lateral movement, model misuse, and other early warning signs of attacks. Predict and prevent potential threats by using AI-powered analytics. Map external exposures to real-world attacker tactics, techniques, and procedures (TTPs) using frameworks like MITRE. 8. Encrypt data Encrypting data and storing encryption keys securely keeps data undecipherable in the event of a breach. However, with the rise of AI and edge computing, you need more than encryption in transit (TLS) and at rest (AES). Tips: Leverage confidential computing techniques like hardware-enforced trusted execution environments (TEEs) for encryption in use (during processing, e.g., for AI model training). Future-proof your data with quantum-resistant cryptography, like hash or code-based cryptography. 9. Automate compliance management Regulatory standards change frequently as technologies and security risks evolve. Companies must stay on top of their compliance posture . Tips: Use automated compliance management tools that keep up with evolving frameworks, including AI-specific standards like the NIST AI RMF and EU AI Act, as well as new policies from PCI DSS, NIST, etc. Maintain regular audit trails to provide audit-ready proof demonstrating your compliance with regulatory bodies and customers. 10. Incident management Having incident management procedures, including prevention and response playbooks, means teams are not left scrambling when incidents happen, i.e., when tensions are usually high and mistakes costly. Tips: Automate incident response with tools that offer autonomous context-based remediation and AI-augmented playbooks; this shortens the compromise-to-containment window.
