Tags Share this article 3/31/21 Published Attacks on water treatment plants show just how vulnerable critical infrastructure is to hacking – here’s how these vital services should be protected. Criminals plotting to poison a city’s water supply is a recurring theme in TV and movie thrillers, such as 2005’s Batman Begins. But as we’ve seen recently, it’s more than just a plot device: it’s a cyber-threat which is all too real. During the past 12 months, there have been two high-profile attacks on water treatment systems that serve local populations, both with the aim of causing harm to citizens. The first was in April 2020, targeting a plant in Israel . Intelligence sources said that hackers gained access to the plant and tried altering the chlorine levels in drinking water – but luckily the attack was detected and stopped. And in early February, a hacker gained access to the water system of Oldsmar, Florida and tried to pump in a dangerous amount of sodium hydroxide. The hacker succeeded in starting to add the chemical, but luckily a worker spotted what was happening and reversed the action. But what could have happened if those timely interventions had not been made? These incidents are a clear reminder that critical national infrastructure is vulnerable to attacks – and that those attacks will keep on happening, with the potential to impact the lives of millions of people.  And of course, the Covid-19 pandemic has further highlighted how essential critical infrastructure is to our daily lives. So how can better security be built into critical infrastructure systems, to stop attackers being able to breach them and disrupt day-to-day operations?  It’s a huge challenge, because of the variety and complexity of the networks and systems in use across different industry sectors worldwide. Different systems but common security problems For example, in water and power utilities, there are large numbers of cyber-physical systems consisting of industrial equipment such as turbines, pumps and switches, which in turn are managed by a range of different industrial control systems (ICS). These were not designed with security in mind:  they are simply machines with computerized controllers that enact the instructions they receive from operators.  The communications between the operator and the controllers are done via IP-based networks – which, without proper network defenses, means they can be accessed over the Internet – which is the vector that hackers exploit. As such, irrespective of the differences between ICS controls, the security challenges for all critical infrastructure organizations are similar:  hackers must be stopped from being able to infiltrate networks; if they do succeed in breaching the organization’s defenses, they must be prevented from being able to move laterally across networks and gain access to critical systems. This means  network segmentation  is one of the core strategies for securing critical infrastructure, to keep operational systems separate from other networks in the organization and from the public Internet and surround them with security gateways so that they cannot be accessed by unauthorized people. In the attack examples we mentioned earlier, properly implemented segmentation would prevent a hacker from being able to access the PC which controls the water plant’s pumps and valves. With damaging ransomware attacks increasing over the past year, which also exploit internal network connections and pathways to spread rapidly and cause maximum disruption,  organizations should also employ security best-practices to block or limit the impact of ransomware attacks  on their critical systems. These best practices have not changed significantly since 2017’s massive WannaCry and NotPetya attacks, so organizations would be wise to check and ensure they are employing them on their own networks. Protecting critical infrastructure against cyber-attacks is a complex challenge because of the sheer diversity of systems in each sector.  However, the established security measures we’ve outlined here are extremely effective in protecting these vital systems – and in turn, protecting all of us.

Cyber Attacks & Incident Response Checking the cybersecurity pulse of medical devices Prof. Avishai Wool 2 min read Prof. Avishai Wool Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 6/14/16 Published Hospitals are increasingly becoming a favored target of cyber criminals. Yet if you think about medical equipment that is vulnerable to being hacked at a hospital, you might not immediately think of high-end, critical equipment such as MRI and X-ray scanners, and nuclear medicine devices. After all, these devices go through rigorous approval processes by the US Food & Drug Administration (FDA) before they are approved for safe use on patients. Yet today many, if not most, medical devices, have computers embedded in them, are connected to the hospital network, and often to the internet as well, so they provide a potential attack vector for cyber criminals. In late 2015 security researchers found that thousands of medical devices were vulnerable to attack and exposed to the public Internet. Interestingly, these researchers also found that many of the devices in question were running Windows XP – which is no longer supported or updated by Microsoft – and did not run antivirus software to protect them against malware. This combination raises an obvious security red flag. Ironically, these security vulnerabilities were further exacerbated because of the very FDA approvals process that certifies the devices. The approval process is, quite rightly, extremely rigorous. It is also lengthy and expensive. And if a manufacturer or vendor makes a change to a device, it needed to be re-certified. Until very recently, a ‘change’ to a medical device meant any sort of change – including patching devices’ operating systems and firmware to close off potential network security vulnerabilities. You can see where this is going: making simple updates to medical equipment to improve its defenses against cyberattacks was made that much more difficult and complex for the device manufacturers, because of the need for FDA re-certification every time a change was made. And of course, this potential delay in patching vulnerabilities made it easy for a hacker to try and ‘update’ the device in his own way, for criminal purposes. Hackers are usually not too concerned about getting FDA approval for their work. Fortunately, the FDA released new guidelines last year that allowed equipment manufacturers to patch software as required without undergoing re-certification—provided the change or modification does not ‘significantly affect the safety or effectiveness of the medical device’. That’s good news – but it’s not quite the end of the story. The FDA’s guidelines are only a partial panacea to the overall problem. They overlook the fact that many medical devices are running obsolete operating systems like Windows XP. What’s more, the actual process of applying patches to the computers in medical devices can vary enormously from manufacturer to manufacturer, with some patches needing to be downloaded and applied manually, while others may be pushed automatically. In either case, there could still be a window of weeks, months or even years before the device’s vendor issues a patch for a given vulnerability – a window that a hacker could exploit before the hospital’s IT team becomes aware that the vulnerability exists. This means that hospitals need to take great care when it comes to structuring and segmenting their network . It is vital that connected medical devices – particularly those where the internal OS may be out of date – are placed within defined, segregated segments of the network, and robustly protected with next-generation firewalls, web proxies and other filters. While network segmentation and filtering will not protect unpatched or obsolete operating system, they will ensure that the hospital’s network is secured to the best of its ability .

Cloud Security Understanding Security Considerations in IaaS/PaaS/SaaS Deployments Rony Moshkovich 2 min read Rony Moshkovich Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/24/22 Published Knowing how to select and position security capabilities in different cloud deployment models is critical to comprehensive security across your organization. Implementing the right pattern allows you to protect the confidentiality, integrity, and availability of cloud data assets. It can also improve incident response to security threats. Additionally, security teams and cloud security architects no longer have to rely on pre-set security templates or approaches built for on-premises environments. Instead, they must adapt to the specific security demands of the cloud and integrate them with the overall cloud strategy. This can be accomplished by re-evaluating defense mechanisms and combining cloud-native security and vendor tools. Here, we’ll break down the security requirements and best practices for cloud service models like IaaS, PaaS, and SaaS. Do you have cloud security architects on board? We’ll also cover their roles and the importance of leveraging native security tools specific to each model. Managing Separation of Responsibilities with the Cloud Service Provider Secure cloud deployments start with understanding responsibilities. Where do you stand, and what is expected of you? There are certain security responsibilities the cloud security provider takes care of and those that the customer handles. This division of responsibilities means adjusting focus and using different measures to ensure security is necessary. Therefore, organizations must consider implementing compensating controls and alternative security measures to make up for any limitations in the cloud service provider’s security offerings. Security Considerations for SaaS (Software-as-a-Service) Deployments The specific security requirements in SaaS deployments may vary between services. However, it’s important to consider the following areas: Data protection During cloud deployments, protecting data assets is a tough nut to crack for many organizations. As a SaaS provider, ensuring data protection is crucial because you handle and store sensitive customer data. Encryption must be implemented for data in transit and at rest. Protecting data at rest is the cloud provider’s responsibility, whereas you are responsible for data in transit. The cloud provider implements security measures like encryption, access controls, and physical security to protect the data stored in their infrastructure. On the other hand, it’s your responsibility to implement secure communication protocols like encryption, ensuring data remains protected when it moves between your SaaS application. Additionally, best practice solutions may offer you the option of managing your encryption keys so that cloud operations staff cannot decrypt customer data. Interfacing with the Cloud Service There are a number of security considerations to keep in mind when interacting with a SaaS deployment. These include validating data inputs, implementing secure APIs, and securing communication channels. It’s crucial to use secure protocols like HTTPS and to ensure that the necessary authentication and authorization mechanisms are in place. You may also want to review and monitor access logs frequently to spot and address any suspicious activity. Application Security in SaaS During SaaS deployments, it’s essential to ensure application security. For instance, secure coding practices, continuous vulnerability assessments, and comprehensive application testing all contribute to effective SaaS application security. Cross-site scripting (XSS) and SQL injection are some of the common web application cyber-attacks today. You can improve the application’s security posture by implementing the right input validation, regular security patches from the SaaS provider, and web application firewalls (WAFs). Cloud Identity and Access Controls Here, you must define how cloud services will integrate and federate with existing enterprise identity and access management (IAM) systems. This ensures a consistent and secure access control framework. Implementing strong authentication mechanisms like multifactor authentication (MFA) and enforcing proper access controls based on roles and responsibilities are necessary security requirements. You should also consider using Cloud Access Security Broker (CASB) tools to provide adaptive and risk-based access controls. Regulatory Compliance Using a cloud service doesn’t exempt one from regulatory compliance, and cloud architects must design the SaaS architecture to align with these requirements. But why are these stringent requirements there in the first place? The purpose of these regulations is to protect consumer privacy by enforcing confidentiality, integrity, availability, and accountability. So, achieving compliance means you meet these regulations. It demonstrates that your applications and tech stack maintain secure privacy levels. Failure to comply could cost money in the form of fines, legal action, and a damaged reputation. You don’t want that. Security Considerations for PaaS (Platform-as-a-Service) Deployments PaaS security considerations during deployments will address all the SaaS areas. But as a PaaS customer, there are slight differences you should know. For example, more options exist to configure how data is protected and who can do what with it. As such, the responsibility of user permissions may be given to you. On the other hand, some PaaS providers may have built-in tools and mechanisms for managing user permissions. So, what are the other key areas you want to address to ensure a secure environment for PaaS deployments? We’ll start with the application security. Application Security The customer is responsible for securing the applications they build and deploy on the PaaS platform. Securing application platforms is necessary, and cloud architects must ensure this from the design and development stage. So, what do you do to ensure application security? It all starts from the onset. From secure coding practices, addressing application vulnerabilities, and conducting regular security testing. You’ll often find that most security vulnerabilities are introduced from the early stages of software development. If you can identify and fix potential flaws using penetration testing and threat modeling practices, you’re on your way to successful deployment. Data Security PaaS cloud security deployments offer more flexibility and allow customers control over their data and user entitlements. What this means is you can build and deploy your own applications on the platform. You can configure security measures and controls within your applications by defining who has access to applications, what they can do, and how data is protected. Here, cloud security architects and security teams can ensure data classification and access controls, determining appropriate encryption keys management practices, secure data integration and APIs, and data governance. Ultimately, configuring data protection mechanisms and user permissions provides customers with greater customization and control. Platform Security The platform itself, including the operating system, underlying infrastructure, data centers, and middleware, need to be protected. This is the responsibility of the PaaS provider. They must ensure that the components that keep the platform up are functional at all times. Network Security In PaaS environments, identity and roles are primarily used for network security to determine access to resources and data in the PaaS platform. As such, the most important factor to consider in this case is verifying the user identity and managing access based on their roles and permissions. Rather than relying on traditional network security measures like perimeter controls, IDS/IPS, and traffic monitoring, there is a shift to user-centric access controls. Security Considerations for IaaS (Infrastructure-as-a-Service) Cloud Deployments When it comes to application and software security, IaaS security during cloud deployment is similar. If you’re an IaaS customer, there are slight differences in how IaaS cloud deployment is handled. For example, while the cloud provider handles the hypervisor or virtualized layer, everything else is the customers’ responsibility. So, you must secure the cloud deployment by implementing appropriate security measures to safeguard their applications and data. Due to different deployment patterns, some security tools that work well for SaaS may not be suitable for IaaS. For example, we discussed how CASB could be excellent for cloud identity, data, and access controls in SaaS applications. However, this may not be effective in IaaS environments. Your cloud architects and security teams must understand these differences when deploying IaaS. They should consider alternative or additional security measures in certain areas to ensure more robust security during cloud deployments. These areas are: Access Management IaaS deployment requires you to consider several identity and access management (IAM) dimensions. For example, cloud architects must consider access to the operating system, including applications and middleware installed on them. Additionally, they must also consider privileged access, such as root or administrative access at the OS level. Keep in mind that IaaS has additional access layers. These consist of access to the IaaS console and other cloud provider features that may offer insights about or impact the operation of cloud resources. For example, key management and auditing and resource configuration and hardening. It’s important to clarify who has access to these areas and what they can do. Regular Patching There are more responsibilities for you. The IaaS customer is responsible for keeping workloads updated and maintained. This typically includes the OS itself and any additional software installed on the virtual machines. Therefore, cloud architects must apply the same vigilance to cloud workloads as they would to on-premises servers regarding patching and maintenance. This ensures proactive, consistent, and timely updates that ensure the security and stability of cloud workloads. Network Security IaaS customers must configure and manage security mechanisms within their virtual networks. This includes setting firewalls, using intrusion detection and intrusion prevention systems (IDS/IPS), establishing secure connections (VPN), and network monitoring. On the other hand, the cloud provider ensures network security for the underlying network infrastructure, like routers and switches. They also ensure physical security by protecting network infrastructure from unauthorized access. Data Protection While IaaS providers ensure the physical security of data centers, IaaS customers must secure their own data in the IaaS environment. They need to protect data stored in databases, virtual machines (VMs), and any other storage system provisioned by the IaaS provider. Some IaaS providers, especially large ones, offer encryption capabilities for the VMs created on their platform. This feature is typically free or low-priced. It’s up to you to decide whether managing your own encryption keys is more effective or to choose the provider’s offerings. If you decide to go for this feature, it’s important to clarify how encrypting data at rest may affect other services from the IaaS provider, such as backup and recovery. Leveraging Native Cloud Security Tools Just like the encryption feature, some cloud service providers offer a range of native tools to help customers enforce effective security. These tools are available for IaaS, PaaS, and SaaS cloud services. While customers may decide not to use them, the low financial and operational impact of native cloud security tools on businesses makes them a smart decision. It allows you to address several security requirements quickly and easily due to seamless control integration. However, it’s still important to decide which controls are useful and where they are needed. Conclusion Cloud security architecture is always evolving. And this continuous change makes cloud environments more complex and dynamic. From misconfigurations to data loss, many challenges can make secure cloud deployments for IaaS, PaaS, and SaaS services more challenging.

Hybrid Cloud Security Management Deconstructing the Complexity of Managing Hybrid Cloud Security Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/4/22 Published The move from traditional data centers to a hybrid cloud network environment has revolutionized the way enterprises construct their networks, allowing them to reduce hardware and operational costs, scale per business needs and be more agile. When enterprises choose to implement a hybrid cloud model, security is often one of the primary concerns. The additional complexity associated with a hybrid cloud environment can, in turn, make securing resources to a single standard extremely challenging. This is especially true when it comes to managing the behavioral and policy nuances of business applications . Moreover, hybrid cloud security presents an even greater challenge when organizations are unable to fully control the lifecycle of the public cloud services they are using. For instance, when an organization is only responsible for hosting a portion of its business-critical workloads on the public cloud and has little to no control over the hosting provider, it is unlikely to be able to enforce consistent security standards across both environments. Managing hybrid cloud security Hybrid cloud security requires an extended period of planning and investment for enterprises to become secure. This is because hybrid cloud environments are inherently complex and typically involve multiple providers. To effectively manage these complex environments, organizations will require a comprehensive approach to security that addresses each of the following challenges: Strategic planning and oversight : Policy design and enforcement across hybrid clouds Managing multiple vendor relationships and third-party security controls : Cloud infrastructure security controls, security products provided by cloud and third-party providers and third-party on-premise security vendor products. Managing security-enabling technologies in multiple environments : on-premise, public cloud and private cloud. Managing multiple stakeholders : CISO, IT/Network Security, SecOps, DevOps and Cloud teams. Workflow automation : Auto responding to changing business demands requiring provisioning of policy changes automatically and securely across the hybrid cloud estate. Optimizing security and agility : Aligning risk tolerance with the DevOps teams to manage business application security and connectivity. With these challenges in mind, here are 5 steps you can take to effectively address hybrid cloud security challenges. Step 1. Define the security objectives A holistic approach to high availability is focused on the two critical elements of any hybrid cloud environment: technology and processes. Defining a holistic strategy in a hybrid cloud environment has these advantages: Improved operational availability : Ensure continuous application connectivity, data, and system availability across the hybrid estate. Reduced risk : Understand threats to business continuity from natural disasters or facility disruptions. Better recovery : Maintain data consistency by mirroring critical data between primary locations in case of failure at one site through multiple backup sites. Step 2. Visualize the entire network topology The biggest potential point of failure for hybrid cloud deployment is where the public cloud and private environment offerings meet. This can result in a visual gap often due to disparities between in-house security protocols and third-party security standards, precluding SecOps teams from securing the connectivity of business applications. The solution lies in gaining complete visibility across the entire hybrid cloud estate. This requires having the right solution in place that can help SecOps teams discover, track and migrate application connectivity without regard for the underlying infrastructure. Step 3. Use automation for adaptability and scalability The ability to adapt and scale on demand is one of the most significant advantages of a hybrid cloud environment. Invariably, when considering the range of benefits of a hybrid cloud, it is difficult to conceptualize the power of scaling on demand. Still, enterprises can enjoy tremendous benefits when they correctly implement automation that can respond on-demand to necessary changes. With the right change automation solution, change requests can be easily defined and pushed through the workflow without disrupting the existing network security policy rules or introducing new potential risks. Step 4. Minimize the learning curb According to a 2021 Global Knowledge and IT Skills report , 76% of IT decision-makers experience critical skills gaps in their teams. Hybrid cloud deployment is a complicated process, with the largest potential point of failure being where in-house security protocols and third-party standards interact. If this gap is not closed, malicious actors or malware could slip through it. Meeting this challenge requires a unification of all provisions made to policy changes so that SecOps teams can become familiar with them, regardless of any new device additions to the network security infrastructure. This would be applicable to provisions associated with policy changes across all firewalls, segments, zones, micro‐segments, security groups and zones, and within each business application. Step 5. Get compliant Compliance cannot be guaranteed when the enterprise cannot monitor all vendors and platforms or enforce their policies in a standard manner. This can be especially challenging when attempting to apply compliance standardizations across an infrastructure that consists of a multi-vendor hybrid network environment. To address this issue, enterprises must get their SecOps teams to shift their focus away from pure technology management and toward a larger scale view that ensures that their network security policies consistently comply with regulatory requirements across the entire hybrid cloud estate. Summary Hybrid cloud security presents a significant—and often overlooked—challenge for enterprises. This is because hybrid cloud environments are inherently complex, involving multiple providers, and impact how enterprises manage their business applications and overall IT assets.

Network Segmentation Host-based firewalls vs. network-based firewalls for network security?

Duis mattis velit sit leo diam. Tags Share this article 8/28/23 Published Before your organization can move business applications to the cloud, it must deploy network security solutions that can reliably block cybercrime and malware. Firewalls are essential cybersecurity tools that protect network traffic against threat actors. There are many different types of firewalls available, but put the same basic principles in action. Before finding out which types of firewalls offer the best security performance for your cloud implementation, it’s important to cover how firewalls work and what characteristics set them apart. How firewalls work: Different types of firewalls explained Firewalls are best explained through analogy. Think of firewalls as 24/7 security guards with deep knowledge of millions of criminals. Whenever the security guard sees a criminal approaching an access point, they block access and turn the criminal away. This kind of access control is accomplished in a few different ways. Some firewalls inspect packets for suspicious characteristics. Others use stateful inspection to identify malicious traffic. Some incorporate contextual awareness to tell the difference between harmless traffic and cyberattacks . Here are some of the major types of firewalls and how they work: Packet filtering firewalls inspect data traveling through inline junction points like routers and switches. They don’t route data packets themselves, but compare them to a list of firewall rules. For example, they may filter packets that are traveling to untrusted IP addresses and drop them. Circuit-level gateways monitor TCP handshake data and other protocol messages for signs of unauthorized access. These firewalls don’t inspect individual packets or application layer monitoring, though. Proxy firewalls apply application layer filtering that filters data according to a wide range of characteristics. This category includes web application firewalls, which are a type of reverse proxy firewall – they protect the server from malicious traffic by filtering clients before they reach the server. Stateful inspection firewalls examine and compare multiple packets to find out if they are part of an established network session. This offers a high degree of control over incoming and outgoing traffic while providing comprehensive logs on network connections. Next-generation firewalls combine packet inspection, stateful inspection, antivirus, and additional technologies to protect organizations against unknown threats and vulnerabilities. These firewalls are expensive and have high bandwidth requirements, but they also offer a high level of protection. All of these firewalls exist in different forms. Traditional hardware firewalls are physical devices that sit between network devices and the internet. Network-based firewalls are software-defined apps designed to do the same thing. Hardware, software, or cloud? firewall deployment methods compared Organizations have multiple options when deciding to host firewalls on their private networks. The market offers a vast number of security devices and firewall providers, ranging from Cisco hardware to software solutions like Microsoft’s Windows firewall. Large enterprises use a combination of firewall solutions to adopt a multi-layered security posture. This allows them to achieve network scalability and segmentation while offering different levels of protection to data centers, individual devices, and user endpoints. As firewall technology becomes more accessible, smaller organizations are following suit. Here are some of the delivery formats that firewall solutions commonly come in: Network-based Firewalls are self-contained hardware appliances. They typically run custom operating systems using Linux distributions designed for secure computer networking. They can be challenging to configure and deploy, but are appropriate for a wide range of use cases. Host-based Firewalls run as software on a server or other device. You can run host-based firewalls on individual computers, or at the host level of a cloud environment. The firewalls offer granular control over security rules and individual hosts, but consume resources in the process. Cloud Hosted Firewalls are provided by third-party security partners as a service. These firewalls may be entirely managed by a third-party partner, making them ideal for small organizations that can’t afford building their own security infrastructure from the ground up. How to select an optimal firewall solution for your organization Every organization has a unique security risk profile. Finding the right firewall deployment for your organization requires in-depth knowledge of your network’s security vulnerabilities and potential for long-term growth. Some of the issues you have to consider include: Identifying technical objectives for individual firewalls. There are no one-size-fits-all firewall solutions. One solution may match a particular use case that another does not. Both stateless packet inspection firewalls and sophisticated next-generation solutions operate at different levels of the OSI model, which means each device should serve a well-defined purpose. Selecting firewall solutions that match your team’s expertise. Consider your IT team’s technical qualifications. If configuring a sophisticated next-generation firewall requires adding talent with specialized certifications to your team, the cost of that deployment will rise considerably. Deploying firewalls in ways that improve security performance while reducing waste. Optimal firewall architecture requires effective network segmentation and good security policies. Deploying a secure local area network (LAN) and using virtual private networks (VPNs) can help optimize firewall placement throughout the organization. Determining which kinds of traffic inspection are necessary. Different types of network connections require different levels of security. For example, a public-facing Wi-Fi router is far more likely to encounter malicious traffic than an internal virtual local area network (VLAN) that only authenticated employees can access. How to choose between host-based firewalls and network-based firewalls when moving to the cloud Organizations that are transitioning to cloud infrastructure need to completely rethink their firewall deployment strategy. Firewalls are the cornerstone of access control, and cloud-hosted infrastructure comes with the shared responsibility model that puts pressure on security leaders to carefully deploy security resources. In many cases, you’ll face tough decisions concerning which type of firewall to deploy at particular points in your network. Building an optimal deployment means working through the pros and cons of each option on a case-by-case basis. Host-based firewalls and network-based firewalls are the two main options you’ll encounter for most use cases. Let’s look at what each of those options look like from a complete network security perspective . 1. Host-based firewalls offer flexibility but may introduce vulnerabilities A cloud-native organization that exclusively uses host-based firewalls will have a cloud environment filled with virtual machines that take the place of servers and individual computers. To protect those devices, the organization will implement host-based firewalls on every virtual machine and configure them accordingly. This provides the organization with a great deal of flexibility. IT team members can clone virtual machines and move them within the cloud on demand. The host-based firewalls that protect these machines can move right alongside them, ensuring consistent security policies are enforced without painstaking manual configuration. It’s even possible to move virtual machines between cloud environments – like moving a virtual server from Amazon AWS to Microsoft Azure – without having to create completely new security policies in the process. This makes it easy for IT teams to work securely without introducing friction. However, if attackers gain privileged access to host-based firewalls, they gain the same level of control. They may switch off the firewall or install malicious code in ways that other security technologies cannot detect. Even highly secure organizations are subject to this kind of risk. Imagine an attacker compromises the credentials of a system administrator with firewall configuration privileges. Very few obstacles stand between an insider threat and the sensitive data they wish to exfiltrate. Network-based firewalls offer independent security Compared to host-based firewall products, it’s much harder for a malicious insider to compromise a network-based firewall solution managed by a cloud provider. That’s because the physical hardware is operating on a completely separate system from the host. In a cloud-native environment, the network-based firewall would be a fully hardened device managed by a third-party provider running their own intrusion detection systems. This makes it much harder for attackers to successfully infiltrate and compromise systems without being noticed. At the same time, independent network-based firewall architecture means that the attacker would have to compromise both your network and the cloud provider’s network without triggering security alerts from either. This adds a great deal of complexity to any attack, and significantly increases the chance it will be detected. However, few organizations can afford to exclusively deploy hardware firewalls at every layer of their network. Even those that can afford it will run into significant challenges when planning for growth and scalability. Segment your network for optimal protection While they offer increased security, hardware firewalls are costly to deploy and maintain. Most organizations segment their networks in ways that offer extensive multi-layered protection to their most sensitive data while allowing more flexible host-based firewalls to protect less critical assets. Every organization has a unique balance between optimal network-based firewall and host-based firewall deployment. This depends heavily on the volume of sensitive data the organization regularly accesses, and the security of its connections with users and third-party service providers. Proper network segmentation helps reduce the organization’s attack surface and decrease the risk of business disruption.

Cloud Security A secure VPC as the main pillar of cloud security Asher Benbenisty 2 min read Asher Benbenisty Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/11/24 Published Secure VPC as the main pillar of cloud security Remember the Capital One breach back in 2019 ? 100 million customers' data exposed, over $270 million in fines – all because of a misconfigured WAF. Ouch! A brutal reminder that cloud security is no joke. And with cloud spending skyrocketing to a whopping $675.4 billion this year, the bad guys are licking their chops. The stakes? Higher than ever. The cloud's a dynamic beast, constantly evolving, with an attack surface that's expanding faster than a pufferfish in a staring contest. To stay ahead of those crafty cybercriminals, you need a security strategy that's as agile as a ninja warrior. That means a multi-layered approach, with network security as the bedrock. Think of it as the backbone of your cloud fortress, ensuring all your communication channels – internal and external – are locked down tighter than Fort Knox. In this post, we're shining the spotlight on Virtual Private Clouds (VPCs) – the cornerstone of your cloud network security. But here's the kicker: native cloud tools alone won't cut it. They're like a bicycle in a Formula 1 race – good for a leisurely ride, but not built for high-speed security. We'll delve into why and introduce you to AlgoSec, the solution that turbocharges your VPC security and puts you in the driver's seat. The 5 Pillars of Cloud Security: A Quick Pit Stop Before we hit the gas on VPCs, let's do a quick pit stop to recap the five foundational pillars of a rock-solid cloud security strategy: Identity and Access Management (IAM): Control who gets access to what with the principle of least privilege and role-based access control. Basically, don't give the keys to the kingdom to just anyone! Keep a watchful eye with continuous monitoring and logging of access patterns. Integrate with SIEM systems to boost your threat detection and response capabilities. Think of it as having a security guard with night vision goggles patrolling your cloud castle 24/7. Data Encryption: Protect your sensitive data throughout its lifecycle – whether it's chilling in your cloud servers or traveling across networks. Think of it as wrapping your crown jewels in multiple layers of security, making them impenetrable to those data-hungry thieves. Network Security: This is where VPCs take center stage! But it's more than just VPCs – you also need firewalls, security groups, and constant vigilance to keep your network fortress impenetrable. It's like having a multi-layered defense system with moats, drawbridges, and archers ready to defend your cloud kingdom. Compliance and Governance: Don't forget those pesky regulations and internal policies! Use audit trails, resource tagging, and Infrastructure as Code (IaC) to stay on the right side of the law. It's like having a compliance officer who keeps you in check and ensures you're always playing by the rules. Incident Response and Recovery: Even with the best defenses, breaches can happen. It's like a flat tire on your cloud journey – annoying, but manageable with the right tools. Be prepared with real-time threat detection, automated response, and recovery plans that'll get you back on your feet faster than a cheetah on Red Bull. Why Network Security is Your First Line of Defense Network security is like the moat around your cloud castle, the first line of defense against those pesky attackers. Breaches can cost you a fortune, ruin your reputation faster than a bad Yelp review, and send your customers running for the hills. Remember when Equifax suffered a massive data breach in 2017 due to an unpatched vulnerability? Or the ChatGPT breach in 2023 where a misconfigured database exposed sensitive user data? These incidents are stark reminders that even a small slip-up can have massive consequences. VPCs: Building Your Secure Cloud Fortress VPCs are like creating your own private kingdom within the vast public cloud. You get to set the rules, control access, and keep those unwanted visitors out. This isolation is crucial for preventing those sneaky attackers from gaining a foothold and wreaking havoc. With VPCs, you have granular control over your network traffic – think of it as directing the flow of chariots within your kingdom. You can define routing tables, create custom IP address ranges, and isolate different sections of your cloud environment. But here's the thing: VPCs alone aren't enough. You still need to connect to the outside world, and that's where secure options like VPNs and dedicated interconnects come in. Think of them as secure tunnels and bridges that allow safe passage in and out of your kingdom. Native Cloud Tools: Good, But Not Good Enough The cloud providers offer their own security tools – think AWS CloudTrail, Azure Security Center, and Google Cloud's Security Command Center. They're a good starting point, like a basic toolkit for your cloud security needs. But they often fall short when it comes to dealing with the complexities of today's cloud environments. Here's why: Lack of Customization: They're like one-size-fits-all suits – they might kinda fit, but they're not tailored to your specific needs. You need a custom-made suit of armor for your cloud kingdom, not something off the rack. Blind Spots in Multi-Cloud Environments: If you're juggling multiple cloud platforms, these tools can leave you with blind spots, making it harder to keep an eye on everything. It's like trying to guard a castle with multiple entrances and only having one guard. Configuration Nightmares: Misconfigurations are like leaving the back door to your castle wide open. Native tools often lack the robust detection and prevention mechanisms you need to avoid these costly mistakes. You need a security system with motion sensors, alarms, and maybe even a moat with crocodiles to keep those intruders out. Integration Headaches: Trying to integrate these tools with other security solutions can be like fitting a square peg into a round hole. This can leave gaps in your security posture, making you vulnerable to attacks. You need a security system that works seamlessly with all your other defenses, not one that creates more problems than it solves.

What is endpoint security and its functionality? Endpoint security tools protect individual devices like desktop workstations, laptop computers, and mobile phones from cyber attacks. This usually means installing an endpoint security client on the device which regularly scans for malware and inspects user behaviors to detect signs of unauthorized access. Mobile devices are particularly important to endpoint security because they can change location or get lost or stolen. Many advanced endpoint security tools offer additional features to detect malicious insiders who may have gained access to a legitimate user’s mobile device. What are firewalls in network security? Firewalls are devices that inspect network traffic. They typically sit at the edge of the network, protecting internal network assets from receiving malicious content from outside the network. Traditional firewalls look for packet and port data that indicates unauthorized activity and filter out connections that don’t appear legitimate. Next-generation firewalls offer a much wider range of capabilities to security teams. They can conduct deep packet inspection and identify traffic that belongs to particular apps or users. Some NGFW devices can even detect when sensitive data is being sent out of the network and block the attempt. What is Network Access Control (NAC)? Network access control solutions provide visibility into the actions users take on a network. They enable security teams to enforce access management policies on devices throughout the network. Without an NAC solution in place, security tools would have a much harder time recognizing users and devices based on their usage profiles, or managing permissions and authentication policies without using a separate access control solution. What is Zero Trust Network Access (ZTNA)? Zero Trust Network Access provides secure remote access to the data, applications, and service hosted on a network. It does this through a set of strictly defined access control policies that do not extend trust to users based on their previous behaviors. With a ZTNA policy in place, a malicious user who impersonates an employee and gains access to one segment of the network would not necessarily be able to move onto another segment of the network. How does Zero Trust secure cloud environments within enterprise networks? Cloud-enabled network infrastructure provides a more complex security profile than simple on-premises infrastructure. This is because the organization may not control the entire network, and it may not be able to establish boundaries for that network on its own. Security leaders need to deploy a more complex set of firewalls, proxies, and threat detection solutions to securely access cloud-hosted assets while still complying with Zero Trust. What is the Role of Network Segmentation in Reducing Attack Surface? Network segmentation puts obstacles up between different parts of the network. If attackers compromise one segment of the network, they will be unable to gain instant access to the rest of the network. Instead, they will have to spend additional time and resources breaking into other network segments. This increases the chance that security teams can detect the intruder and remediate the attack before catastrophic damage is done. What is Secure Access Service Edge (SASE)? SASE is an emerging concept that provides a level of security appropriate to complex cloud-enabled enterprises with distributed remote users. It combines wide area network (WAN) with network security services like CASB, firewall-as-a-service, and Zero Trust into a unified service delivered through the cloud. This gives security leaders real-time data on their cloud security posture and allows them to accurately assess network risks continuously. What is threat detection and threat intelligence? Threat detection tools include Intrusion Prevention Systems (IPS), sandboxes, and Security Information and Event Management platforms: Intrusion Prevention Systems (IPS) identify and block unauthorized network activity, often in conjunction with firewalls and other security tools. Sandboxing allows users to download and open suspicious files in a simulated IT environment. If the file launches malware, the sandbox application will close and delete the file without allowing it to harm the system. Security Information and Event Management (SIEM) platforms allow security operations personnel to conduct real-time monitoring and respond to threats as soon as they occur. How do network security solutions help with data loss prevention? (DLP) Network security tools prevent hackers from interacting with sensitive data and block attempts to exfiltrate that data and use it to extort users. DLP solutions help security teams identify and classify sensitive information so that they can put the appropriate security controls in place to protect it. Without this step, it would be very difficult to tell when data breaches result in the loss of protected data because security teams would not have a clear idea of where that data is. In addition to network security, many organizations are also relying on enterprise data backup and recovery solutions in the event of a disaster, their cloud data is preserved and easily retrievable. Can network security solutions help with email security? Some network security tools include valuable email security and anti-phishing features. For example, some next-generation firewalls can detect when authorized users attempt to input their login credentials on spoofed websites. They prevent the data from leaving the network and warn the user that they have been targeted by a phishing attack. Multi-layered security solutions are crucial to establishing secure workflows. What is the role of Virtual Private Networks (VPN) in Network Security? VPNs allow users to encrypt their traffic and interact with protected information even when they don’t trust their own internet connection. This is important for employees interacting with remote records while traveling, where hackers can easily create fake Wi-Fi hotspots designed to look like well-known public networks. Some VPNs also anonymize user identities, allowing them to access content they would not otherwise be able to. What is IoT’s impact on Network Security? The Internet of Things presents many challenges to operational security, especially for large enterprises and industrial organizations. IoT devices rarely benefit from the kind of built-in security protections that desktop workstations and mobile phones have, making them an easy target for hackers. Security leaders need to group IoT devices together and protect them with strict security policies enforced by high quality firewalls and other tools. Mitigating Distributed Denial of Service (DDoS Attacks) Hackers may attack organizations by preventing other users from accessing their services. They may even use these attacks to disrupt firewalls and create an opening through which they can launch additional attacks. Protecting network assets from DDoS attacks requires implementing firewalls that can detect these attacks and drop the malicious connections hackers are trying to make. Next-generation firewalls have additional resources available for doing this, and can even defend against complex multi-session attacks. What are network security best practices? Network security policies and firewall rules must balance the need for security with the need for easy and accessible workflows. If security tools prevent legitimate users from accessing the assets they need, it may impact production. Similarly, security leaders need to deploy limited resources efficiently. Automation helps ensure security team members can dedicate their time to important strategic initiatives instead of high-volume, low-impact tasks. What is the role of Managed Security Service Providers (MSSPs)? MSSPs help growing organizations enhance operational security without requiring them to build, deploy, and staff their own security operations center. This allows them to save a great deal of money compared to the cost of building in-house security capabilities. It also grants organizations access to specialist security talent they might not otherwise be able to afford. Instead of paying for unpredictable security expenditures, organizations can pay a consistent monthly fee according to the services they actually use.

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 Horizon Security 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. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?

Tags Share this article 7/15/14 Published Insecure Service Protocols and Ports Okay, we all have them… they’re everyone’s dirty little network security secrets that we try not to talk about. They’re the protocols that we don’t mention in a security audit or to other people in the industry for fear that we’ll be publicly embarrassed. Yes, I’m talking about cleartext protocols which are running rampant across many networks. They’re in place because they work, and they work well, so no one has had a reason to upgrade them. Why upgrade something if it’s working right? Wrong. These protocols need to go the way of records, 8-tracks and cassettes (many of these protocols were fittingly developed during the same era). You’re putting your business and data at serious risk by running these insecure protocols. There are many insecure protocols that are exposing your data in cleartext, but let’s focus on the three most widely used ones: FTP, Telnet and SNMP. FTP (File Transfer Protocol) This is by far the most popular of the insecure protocols in use today. It’s the king of all cleartext protocols and one that needs to be smitten from your network before it’s too late. The problem with FTP is that all authentication is done in cleartext which leaves little room for the security of your data. To put things into perspective, FTP was first released in 1971, almost 45 years ago. In 1971 the price of gas was 40 cents a gallon, Disneyland had just opened and a company called FedEx was established. People, this was a long time ago. You need to migrate from FTP and start using an updated and more secure method for file transfers, such as HTTPS, SFTP or FTPS. These three protocols use encryption on the wire and during authentication to secure the transfer of files and login. Telnet If FTP is the king of all insecure file transfer protocols then telnet is supreme ruler of all cleartext network terminal protocols. Just like FTP, telnet was one of the first protocols that allowed you to remotely administer equipment. It became the defacto standard until it was discovered that it passes authentication using cleartext. At this point you need to hunt down all equipment that is still running telnet and replace it with SSH, which uses encryption to protect authentication and data transfer. This shouldn’t be a huge change unless your gear cannot support SSH. Many appliances or networking gear running telnet will either need the service enabled or the OS upgraded. If both of these options are not appropriate, you need to get new equipment, case closed. I know money is an issue at times, but if you’re running a 45 year old protocol on your network with the inability to update it, you need to rethink your priorities. The last thing you want is an attacker gaining control of your network via telnet. Its game over at this point. SNMP (Simple Network Management Protocol) This is one of those sneaky protocols that you don’t think is going to rear its ugly head and bite you, but it can! escortdate escorts . There are multiple versions of SNMP, and you need to be particularly careful with versions 1 and 2. For those not familiar with SNMP, it’s a protocol that enables the management and monitoring of remote systems. Once again, the strings can be sent via cleartext, and if you have access to these credentials you can connect to the system and start gaining a foothold on the network, including managing, applying new configurations or gaining in-depth monitoring details of the network. In short, it a great help for attackers if they can get hold of these credentials. Luckily version 3.0 of SNMP has enhanced security that protects you from these types of attacks. So you must review your network and make sure that SNMP v1 and v2 are not being used. These are just three of the more popular but insecure protocols that are still in heavy use across many networks today. By performing an audit of your firewalls and systems to identify these protocols, preferably using an automated tool such as AlgoSec Firewall Analyzer , you should be able to pretty quickly create a list of these protocols in use across your network. It’s also important to proactively analyze every change to your firewall policy (again preferably with an automated tool for security change management ) to make sure no one introduces insecure protocol access without proper visibility and approval. Finally, don’t feel bad telling a vendor or client that you won’t send data using these protocols. If they’re making you use them, there’s a good chance that there are other security issues going on in their network that you should be concerned about. It’s time to get rid of these protocols. They’ve had their usefulness, but the time has come for them to be sunset for good. Schedule a demo Related Articles Q1 at AlgoSec: What innovations and milestones defined our start to 2026?
