Webinars Horizon AppViz Ablaze? Ablaze? Put Out Network Security Audit & Compliance Fires The growing body of regulations and standards forces enterprises to put considerable emphasis on compliance verified by ad hoc and regular auditing of security policies and controls. While regulatory and internal audits entail a wide range of security checks, network firewalls are featured prominently as they are the first line of defense of the enterprise network. Typical networks might include tens or hundreds of firewalls from multiple vendors running thousands of rules. Auditing firewalls for compliance is becoming more complex and demanding all the time. Documentation of current rules and their evolution of changes is lacking Time and resources required to find, organize and inspect all the firewall rules to determine the level of compliance is exorbitant and growing It’s time to adopt auditing’s best practices to maintain continuous compliance. Join us in this webinar to discover the Firewall Audit Checklist, the 6 best practices that will ensure successful audits and full compliance.

In the context of the Zero Trust vs. least privilege debate, this post explores the difference between Zero Trust and least privilege, how the Zero Trust security model and least privilege access control work together, and where each fits in a modern security program. Organizations need both Zero Trust and least privilege. These two fundamental security approaches verify all requests and restrict all permissions. This article explains the operation of each security method as well as their distinct approaches to defense. It also provides guidance on their combined use for enhanced security. Zero trust vs least privilege 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. Zero Trust vs. Least Privilege: What's the Difference and How Do They Work Together? In the context of the Zero Trust vs. least privilege debate, this post explores the difference between Zero Trust and least privilege, how the Zero Trust security model and least privilege access control work together, and where each fits in a modern security program. Organizations need both Zero Trust and least privilege. These two fundamental security approaches verify all requests and restrict all permissions. This article explains the operation of each security method as well as their distinct approaches to defense. It also provides guidance on their combined use for enhanced security. Zero Trust vs. Traditional Security Security operations previously focused on creating an unbreakable defensive boundary. The rule was: Trust the people and devices inside the network. Be suspicious of everything on the outside. This "castle-and-moat" security model proved effective when technology systems were run from restricted server rooms. But cloud computing, SaaS solutions, and hybrid work environments have resulted in traditional system perimeters dissolving. Cloud, SaaS, and remote endpoints now make up a fragmented and complex “frontline,” with inconsistent controls that create gaps attackers can exploit. Malicious actors know that if they find one unlocked door—usually a stolen password—they can often wander freely through the entire network. This is precisely what the Zero Trust security model was designed to prevent. What Is the Zero Trust Security Model? The Zero Trust security model follows a single core belief surrounding verification. The new rule is: All users and systems must require verification before being granted access. Under this model, there is no free pass. Every single time someone or something tries to access a resource, they must authenticate their identity and prove they have access rights to the resources they seek. What Are the Building Blocks of Zero Trust Access Management? Making a Zero Trust architecture work requires a few key components: Policy decision point (PDP): The PDP operates as the central regulatory system of the entire network. It's where you define and store all the rules about who has access to what. Policy enforcement point (PEP): This is your security guard. The system functions as a security checkpoint that protects all resources while implementing the policies defined by the PDP. Trust algorithm: This evaluates various real-time indicators (e.g., user identity, device health status, location data, and data sensitivity) to generate a trust score for each request. Zero Trust Architecture in Practice Implementing Zero Trust requires organizations to establish ongoing verification processes for all identity and device access, as well as network, workload, and data security: Devices: Companies must verify the security posture of all laptops and phones through software updates and security tool verification. The testing process identifies non-compliant devices, which are placed in a digital waiting area until they achieve safety standards. Networks: Micro-segmentation is the main player here. By dividing your network into tiny, isolated zones, you prevent an intruder from moving around freely. All traffic between servers (east-west) needs to be encrypted and pass through a PEP checkpoint. Applications & workloads: Applications, together with services, require robust identity systems. This can be done using methods like mTLS to ensure services are securely talking to each other, and by enforcing strict authorization checks at the front door (gateways) of every application. Data : Are you fully aware of what your data cons ists of and its level of sensitivity? The process of classification and labeling enables organizations to develop smart policies that implement least privilege access controls, preventing sensitive information from leaving the organization. The Least Privilege Principle and Least Privilege Access Control Following the least privilege principle, least privilege access control requires that all users and non-human identities receive permissions that exactly match their required tasks and only remain active during the time needed to complete those tasks. Limiting permissions to specific times and tasks: Minimizes system vulnerabilities Restricts damage from compromised credentials Prevents unauthorized system access Makes audit processes easier and regulatory requirements more achievable Provides clear visibility into all access elevation activities Teams use three main operational controls to implement least privilege in their daily operations: RBAC/ABAC function together to restrict resource access based on job titles and user characteristics ; RBAC handles basic access control, while ABAC offers detailed context-based authorization checks. Just-in-time (JIT) allows a user to ask for special permissions for a short period to perform a specific task, with any rights granted terminated when the work is complete. Time-boxed tokens grant access credentials with an expiration date, so even if a token is stolen, exposure is short‑lived and any impact contain ed. How Do You Implement Least Privilege Access Control? The implementation of least privilege access control requires a methodical approach to provide each identity with the smallest set of permissions needed to perform its duties for a limited duration. These are the essential steps for successful implementation: Inventory and map privileges: You cannot protect what you do not even know is yours. This step demands complete identification of human and machine identities to establish their current permissions and necessary access permissions. Shrink service account scopes: After creating a map, you can begin to limit the permissions of accounts that have excessive access. Credential rotation and exceptions: Organizations need to adopt credential rotation and temporary identity systems for automated operations while also making just-in-time access their default security approach. The Difference Between Zero Trust and Least Privilege The discussion of Zero Trust vs. least privilege comes down to the two concepts dealing with different security issues. Zero Trust vs. Least Privilege The table below presents a clear comparison. Feature Zero Trust Least Privilege Scope & Purpose The overall game plan for securing the entire organization A core access‑management principle limiting each identity to the minimum permissions required for specific tasks/resources Decision Focus Evaluation of whether to trust the present request Stopping users from getting unintended and extra access Primary Goal To get rid of assumed trust and verify everything, always To limit the damage if an account or system gets compromised Ownership Usually driven by the security and platform architecture teams Put into practice by the people who own the data and applications Conclusion Zero Trust and least privilege security solutions deliver a major security improvement when deployed together, despite their distinct implementation methods. Their combination significantly reduces the potential damage from a breach, makes it much harder for attackers to move around, and delivers a crystal-clear record of who is accessing what and why. If you’re evaluating platforms to operationalize these practices, AlgoSec can help by: Modeling application connectivity Orchestrating network security policy changes Supporting micro-segmentation Maintaining continuous compliance across hybrid and multi‑cloud environments All these capabilities reinforce both Zero Trust and least privilege.

Overcome hybrid and multi-cloud security challenges with strategies to enhance visibility, enforce policies, and protect data across diverse cloud environments. Hybrid & multi-cloud Security challenges Overview Cloud computing provides improved security, agility, and flexibility. However, integrating this new service into legacy IT environments comes with some great concerns. In a recent survey conducted by the Cloud Security Alliance (CSA) and AlgoSec, security, data loss and compliance were identified as the top 3 concerns when moving to the cloud. Schedule a Demo Survey creation and methodology The Cloud Security Alliance is a not-for-profit organization with a mission to widely promote best practices for ensuring cyber security in cloud computing and IT technologies. CSA is also tasked with educating various stakeholders within these industries about security concerns in all other forms of computing. CSA’s membership is comprised of a broad coalition of industry practitioners, corporations, and professional associations. One of CSA’s primary goals is to conduct surveys that assess information security trends. These surveys help gauge the maturity of information security technology at various points in the industry, as well as the rate of adoption of security best practices. AlgoSec, a leading network security solution provider, commissioned CSA to develop a survey to add to the industry’s knowledge about hybrid-cloud and multi-cloud security, and to prepare this report of the survey’s findings. Algosec financed the project and co-developed the initiative by participating with CSA in the development of survey questions addressing hybrid cloud security. The survey was conducted online by CSA, from December 2018 to February 2019, and was submitted to nearly 700 IT and security professionals from a variety of organization sizes and locations. Approximately 500 organizations answered the majority of the 20-question survey. The data analysis presented here was performed by CSA’s research team. Schedule a Demo Introduction Year after year, the adoption of cloud technologies continues to increase. Companies of all sizes are taking advantage of the value in cloud computing with its improved security, agility, and flexibility all of which are crucial for success in today’s market. However, like any technology, cloud computing comes with particular concerns and complications, especially when integrating multiple different cloud services with legacy IT environments. To complicate things further, cloud platforms include ecosystems of services that aren’t always fully compatible with each other, causing data ownership and interoperability issues. Today’s cloud adoption requires focused attention on data migration, expert levels of knowledge per service, and an understanding of vendor security and responsibility. One of the challenges of this multi-cloud integration is assigning assets to different types of cloud environments, including public and private cloud services, as well as multiple cloud public platforms and services. The various cloud options must also be integrated with on-premise networks and other third-party services. To top it all off, the final computing environment your organization achieves, regardless of its complexity, must be able to remain secure and stay current with regulatory compliance protocols. To gain a better understanding of information security concerns in this complex environment, the Cloud Security Alliance (CSA), in cooperation with AlgoSec, surveyed 700 IT professionals on the following topics related to cloud usage within their enterprises: Types of cloud platforms in use Proportion of workloads actively in the cloud New workloads expected to be moved into the cloud Anticipated risks and concerns about potential migrations to the cloud Challenges managing security after adopting cloud technologies Methods for addressing these security challenges Challenges related to network or application outages Methods for and results of addressing outages and security incidents Schedule a Demo Key findings This survey demonstrated the complex nature of today’s cloud computing environment, and its attendant concerns regarding the management of security risks. The survey also identified potential disconnects and misinformation in the industry related to the importance of visibility into critical cloud resources and the professional security expertise necessary when using cloud services. The survey illustrates the need within our industry to better address these issues before adopting cloud technologies in order to create practical and manageable network environments–rather than simply putting out fires as they arise after deploying new technologies. It also highlighted the need to maintain cloud service specific knowledge during the growth of the service in order to stay current with new features and functionality. Lack of visibility into cloud resources Organizations adopting new technologies in the public cloud may not be considering the potential risks related to visibility until they eventually encounter security problems in practice. A third of respondents (39%) identified visibility as a concern that had arisen when their organization considered adopting a public cloud. However, more than three-quarters of respondents rated visibility as a challenge related to managing their security once in the public cloud. When asked about the level of challenge presented by lack of visibility into the entire cloud estate, 44% reported this issue to be a moderate security challenge, and 36% reported it as a maximum challenge. Cloud computing complexity More than half of survey respondents operate within a complex cloud computing environment, including multiple clouds (66% of respondents) and hybrid clouds (55%). Many also rely on a combination of hybrid and multi-cloud technologies (36%). Of the nearly 700 people who were given the survey, less than 10% of the enterprises reported that they do not use any public cloud services. Meanwhile, many respondents expect to increase their use of cloud computing technologies by 2020. The number of enterprises that host more than 40% of their total workloads in a public cloud should double within one year according to their reports. Lack of security expertise While a third of respondents reported lack of expertise as a concern when considering moving to the public cloud, nearly three-quarters of respondents already using the cloud cited this same concern as a challenge for security management. When asked to rate the level of challenge to managing security that is posed by a lack of expertise in cloud-native security constructs, 43% of respondents rated it a moderate challenge, and 30% a maximum challenge. The importance of staff having security expertise is emphasized once again with regards to network and application outages. More than 200 survey respondents indicated their organization had experienced an outage in the previous year. When surveyed about the causes, most respondents reported they did not know its cause (potentially a visibility issue). Another 20% identified the cause as operational human errors and mismanagement of devices. Together, these findings indicate that adequate security expertise may often be an afterthought. Regulatory compliance and legal concerns When enterprises are deciding whether to move their critical resources into a public cloud platform, one of the top three concerns they report is regulatory compliance, with legal concerns following closely behind. More than half of survey respondents (57%) reported these concerns about regulatory compliance, and nearly half indicated a similar unease regarding legal concerns (44%) when adopting public cloud services. These issues remain at the forefront of an organization’s security posture after cloud computing services are adopted. More than three-quarters of respondents found compliance and preparing for audits to be a challenging aspect of managing the security of their public cloud resources (with 45% reporting this to be a moderate challenge and 31% reporting maximum challenge). Schedule a Demo Background on the cloud today In order to reduce costs, increase scalability, and avoid relying on a single provider for all network needs, many organizations use multiple different cloud providers. Most survey respondents (66%) use multiple clouds (defined as a multi-cloud environment). In fact, more than a third (35%) of respondents using cloud leverage 3+ cloud platform vendors*. In addition to this complexity, organizations may use both public and private clouds. More than half (55%) operate in a hybrid-cloud environment (using at a minimum at least one public and at least one private cloud service)**. More than a third (36%) have a combination of multi-cloud and hybrid-cloud environment***. This trend of using both a hybrid cloud and multi-cloud strategy continues to rise and is predicted to increase significantly in the next three years. * Data was obtained by identifying the percentage of respondents who selected more than one provider on either of the questions: Which public cloud platforms does your organization use? or Which private cloud platforms does your organization use? ** Data was obtained by identifying the percentage of respondents who selected at least one public and one private cloud provider from the questions: Which public cloud platforms does your organization use? and Which private cloud platforms does your organization use? *** Data was obtained by identifying the percentage of respondents who selected at least one public and at least one private cloud provider, and also selected more than one public or private cloud provider for the questions: Which public cloud platforms does your organization use? and Which private cloud platforms does your organization use? Over the past decade, enterprises have made plans to move their workloads from data centers to the cloud, and the past two years were no exception. The percentage of enterprises with a majority of their workload in the public cloud (61-100% of workload) has doubled from a survey conducted in 2017 to 14% today. When asked what percentage of workloads an organization is operating in the public cloud, 0- 20% was the most commonly selected response (38% of respondents). About a quarter of respondents (21%) reported hosting between 20 and 40% of their workload in the public cloud, while another quarter (25%) reported already having more than 40% of their total workload in the public cloud. A small sample of highly regulated industries like healthcare and financial services more frequently reported having less of their information (up to 20% of workload) in the cloud, when compared with other industries*. Respondents were also asked to predict the percentage of workload their organization plans to move to the public cloud by the end of 2020. Respondents indicated they expect these workloads to increase, with an approximate doubling of the number of organizations who would likely be hosting more than 40% of their total workloads in the public cloud. While 9% of respondents reported currently not using the cloud for any workload at all, that percentage dropped to 4% in their projections for 2020. Those in the IT industry were more likely to select 81-100% of workload in the cloud (20%) than those in regulated industries like healthcare (7%) and financial services (8%). * The sample size for healthcare was 35 respondents, and finance was 74 respondents Schedule a Demo Concerns and challenges: ensuring security and compliance With easy accessibility to cloud services, each separate business department in an organization has more control and ownership over the services they use. With this increased use, organizations must identify which department(s) will be responsible for security. Most survey respondents (79%) indicated that their IT department held this jurisdiction. Of those responses, just 15% had nominated a dedicated cloud security team within their IT department. Meanwhile, the remaining respondents relied on other security services, such as DevOps or a managed service provider. As easily available as cloud services are and the speed in which they are being adopted, responsibility for security should be considered shared throughout the organization with each business unit understanding the security issues around each service they are using. The vast majority of respondents (81%) expressed concerns about security when considering moving data to the cloud. Respondents’ concerns about data loss and leakage risks were also high (62% of respondents) when considering moving to the public cloud. Companies already face security issues with on-premise solutions. Moving to the cloud can further expose these vulnerabilities, making the need to protect data before migration an important task. The majority of respondents had high levels of concern for security when adopting public cloud platforms, however, more research needs to be conducted to better understand how these concerned users are using their cloud platforms. Using cloud platforms as a hosted service can amplify existing vulnerabilities when directly migrating enterprise applications. Building or re-building within the cloud platform allows enterprise applications to take advantage of cloud native features including security. In addition to common compliance frameworks (e.g. ISO 27001, PCI-DSS, HIPAA, SOX, NIST 800-53), cloud providers are continuously upgrading services and platforms to be compliant with new regulatory policies and industry standards, such as the new European General Data Protection Regulation (GDPR) and CSA Security, Trust, Assurance, Risk (STAR). In recent years, we have seen increased enforcement and greater penalties for security violations. Meanwhile, customers using cloud services may be uncertain about who is liable for any such security violations. More than half of survey respondents (57%) reported concerns about regulatory compliance, and nearly half indicated unease over legal concerns (44%) when adopting public cloud services. There is still ambiguity on how customers leverage these platforms for compliance and who is liable for regulatory violations. Many respondents (39%) indicated that one of the items of concern when moving towards public cloud adoption is visibility into resources in the cloud environment. In a 2017 survey , this concern was significant enough to keep organizations from adopting the public cloud. The need for cloud visibility has given rise to new security tools and vendor solutions to add to the cloud platforms and services that are already being utilized. Leveraging existing standards and open tools can guide organizations in measuring the security, transparency, assurance, and risk of each service. Even with the rise in available security tools, consumers will likely need to push their cloud service providers (CSPs) for higher transparency and accountability. Organizations may also be scrambling to train and acquire talent to manage security skills gaps related to the use of public clouds. These concerns need to be addressed by customers and cloud service providers equally, if the industry hopes to achieve robust security and transparency as a whole. About a third of respondents reported a lack of expertise and a quarter reported lack of staff to manage their cloud environments. Half of this survey’s respondents expressed concern about integrating the public cloud with their current IT infrastructure. Additionally, the above-mentioned 2017 survey found that 61% of respondents already using a hybrid cloud reported that consistent management of security across the hybrid environment is one of their organization’s greatest challenges. With the apparent rise in multi-cloud platform usage and the move to public cloud environments, the skills gap concern will need to address management guidelines for their programs, which includes proper use of provider security tools and default configurations. Less than 2% of respondents mentioned vendor lock-in as a major concern. This correlates to the rise and practice of hybrid cloud and multi-cloud environments, as indicated from earlier analysis. Other interesting findings: Respondents who reported experiencing a cloud-related security incident in the past 12 months were more likely to report lack of staff to manage the cloud environment as a concern (44%) when compared with those who had not experienced a security incident (17%). Of the 58 respondents that recorded experiencing a cloud-related security incident in the past 12 months, 25 reported lack of staff to manage the cloud environment as a concern. Of the 461 respondents that did not record having experiencing a security incident in the past 12 months, 56 reported lack of staff to manage the cloud environment as a concern. Respondents were asked to rate the level of challenge several different issues posed to managing security in the public cloud (no challenge, minimum challenge, moderate challenge, maximum challenge). The issue found most frequently to be a maximum challenge was proactively detecting misconfigurations and security risks, and was followed by a lack of visibility into the entire cloud estate. These challenges, if not managed correctly, can lead to many important security problems. When asked to rate security concerns related to running applications in the public cloud, the highest rated concerns were sensitive customer/personal data leakage, unauthorized access, and infiltration in more sensitive areas in the network (in the cloud or on-prem). Security in the public cloud remains a shared responsibility of providers and end users. To ensure adequate management of security, providers must continue to implement secure default configurations for their customers and alert customers systematically and reliably when these configurations are altered. Meanwhile, when organizations adopt cloud services, it will likely be necessary to acquire tools and staff to manage security properly in these new environments. Schedule a Demo Security management: tools and countermeasues While the use of multi-cloud and hybrid cloud environments can provide many benefits, it also increases the complexity of securing these environments. To better understand how organizations are navigating these complexities, survey respondents were asked what network security controls they use to secure their public cloud deployments. The majority of the respondents reported using more than one security control to manage their public cloud deployments, with the most popular choice being cloud-native security controls (70%). In a similar study performed in 2017, only about a quarter of respondents were using their cloud providers’ native security tools. This indicates a significant increase in the use of CSP native security controls. There was also a significant number of respondents who reported using cloud providers’ additional security controls (58%) and virtual editions of traditional firewalls (45%). Far fewer, reported the utilization of host based enforcement (32%). Security management can take many forms within security application orchestration. Respondents were asked whether they currently manage security as part of their application orchestration process, and the majority (59%) reported yes. To follow up, respondents were then asked what they use to manage security as part of their application orchestration process in public cloud. The responses were mixed. The most common response was orchestration and configuration management tools (33%). Other common responses included cloud native tools (29%). Less common was the use of home-grown scripts leveraging cloud vendors’ APIs (13%). Early detection of potential security risks continues to be an important aspect of security management. The tools utilized to detect and manage these risks or vulnerabilities are vital to early detection. In this survey, about a third of respondents use their cloud providers’ risk assessment service to detect and manage vulnerabilities, while close to a quarter use designated third-party security tools. Another fifth of respondents use generic risk or vulnerability assessment tools. This indicates that less than half are utilizing tools above and beyond what is provided by the CSP. By doing this, organizations’ trust is heavily placed in CSPs’ assessment services without validation and could leave the organization vulnerable. Schedule a Demo Security incidents and cloud outages: preparation and recovery When asked about security concerns related to applications in the public cloud, nearly 90% of this survey’s participants reported moderate or high concern regarding data leakage; unauthorized access; and infiltration of sensitive network areas. About two-thirds reported the same levels of concern about outages due to DoS attacks; data corruption; and resource abuse. Many enterprises are ill-prepared for security incidents, such as breaches and outages. When asked whether their organization had experienced a cloud-related security incident in the last 12 months, 11% reported definitively having had a security incident, and another 30% were either unsure or could not disclose. In the last year, 43% of respondents’ organizations have experienced a network or application outage. Other interesting findings: Respondents from Asia were more likely to report experiencing a cloud-related security incident in the past year (17%) than were respondents from the EU (5%) or the US (8%). Other interesting findings: Respondents in a small sample of regulated industries like healthcare (53%) and financial services (52%) were more likely to report having experienced a network or application outage than those in other industries (33%). The contributors to these outages included both human error and numerous technical problems, such as power outages and hardware failures. When asked to identify the primary contributor to one recent outage, most respondents were unsure of its cause (which may indicate a problem related to visibility). The next most popular answers were operational human errors and mismanagement of devices (20%) and device configuration changes (15%). For over 25% of respondents, it took over 3 hours to restore normal operation. Significant delays could lead to significant revenue loss for an organization through operational inefficiency, lack of productivity, and leaving the organization vulnerable. Other interesting findings: Those who reported having experienced a network or application outage were less likely to have had their outage resolved within an hour (10%), when compared with those who reported having an application outage but no security incidents (42%). Ninety-seven percent of respondents reported their outages were resolved within one working day. Schedule a Demo Conclusions and recommendations Many organizations are migrating more and more of their workloads to cloud-based resources, including hybrid environments, multi-cloud environments, and combinations of the two. These organizations also are working to integrate various applications from public and private cloud providers with their own on-premise resources. As cloud computing environments become even more complex, it is critical for IT professionals to have visibility into their cloud-based resources and to be able to trust the expertise of their own security staff and their cloud provider’s staff. These concerns are underscored by the many new regulatory compliance and legal obligations, making it absolutely necessary for these responsibilities and liabilities to be clearly designated. Build in security and compliance The use of multiple cloud platforms and services offers best in breed capabilities and reduces the reliance on a single vendor. The added need for visibility of data across multiple services has given rise to even more security tools and vendor solutions. This increased adoption of services, combining traditional on-prem and multiple cloud offerings, adds to an already complex environment. This complexity in a cloud environment increases the level of expertise needed to manage and secure these services. Organizations will need to understand how to leverage cloud platforms and use provider tools in order to maximize the full benefits of the cloud. Cloud providers continue to offer native tooling with added visibility and security, often meeting or exceeding other traditional (on-premise and third-party) security controls. Cloud provider platforms and services meet some of the more strict compliance requirements for industry and government regulations. Architecting your IT environment to the services and platforms that are being used allows cloud customers to use cloud native tools for improved security and built-in compliance across complex environments. “ Take responsibility for security internally The cloud service provider and customer IT management teams should be able to articulate their security objectives and establish a baseline level of security requirements that can be measured and shared by both. This shared responsibility approach can go a long way in bolstering transparency and assisting with additional adherence to security regulations and best practices. It is essential for customers to build trust with cloud service providers before migrating any of your organization’s vital resources to the provider’s cloud. Today’s cloud adoption model doesn’t always allow a procurement team to stand between the company data and cloud services being used. The easy adoption and accessibility to cloud services leads to business units throughout organizations using services that are unknown and often undiscovered by IT management and cloud procurement teams. In addition to establishing shared security responsibility with cloud providers, each separate business unit should have a level of awareness of the security objectives established by their organization. Identifying a department responsible for cloud security, establishing cloud security policies across business units, and raising the level of education and awareness for all employees completes the modernized shared responsibility model. The data owner can take responsibility for data security that includes external business partners and internal business units. “ While many capabilities expand in the cloud, existing and future security risks and vulnerabilities unfortunately may also expand. Cloud providers continue to offer more security features and end users are working to increase staff and expertise to manage these tools. Detecting misconfigurations and security risks Training and acquiring staff to manage security remains a challenge for properly implementing cloud services. In addition to staying up-to-date on security best practices, cloud customers struggle to keep up with the rapid advancement of features constantly being added to the cloud services. The cloud providers need to play a role in both securing the cloud services and ensuring that customers are using the services securely. As cloud services evolve, new features are added to improve functionality and security of cloud services. Customer awareness of these features and the training of secure operation should be a priority for the cloud provider upon releasing updates to their services. Additionally, safe and secure default configurations should be implemented to ensure exposed features aren’t turned on without the acknowledgement or understanding of the customers. Finally, customer notification of misconfigurations of publicly exposed services, insufficient credentials, and misuse of any features should be a built-in part of the service. Cloud customers and providers need to work together to improve the overall operation, management, and security of cloud services.“ When to automate The increased adoption of cloud services and features must be met with a skill set that matches the complex cloud environment. The skills to increase visibility and security in cloud service operations involves the training of people toward the management of each service and the ability to automate features when possible. Automating components of your security aids in the lack of expertise and staff to manage a complex cloud environment. Log activity, data aggregation, threat detection, and security policy management are just a few pieces of where automation can help more quickly and accurately identify security gaps, compliance violations, service misconfigurations, service outages, and other anomalous behaviors. As we look to accelerate the use of new technologies, devices, and users in the cloud environment, automation promises to help organizations and their staff keep up with the security and operational demands of tomorrow’s cloud.” Organizations are continuing to migrate more of their workload into complex cloud environments such as hybrid, multi-cloud, and a combination of the two. These environments are the new reality for organizations and addressing security concerns and challenges, discovered through this survey, is of the utmost importance. Security challenges arise in these complex environments due to several factors including lack of visibility, regulatory compliance and legal concerns, and lack of staff expertise. Organizations are able to remedy the situation by building in security and compliance, proactively taking responsibility of security, establishing safe and secure default configurations, and utilizing automation.

Tags Share this article 8/10/15 Published Last week our CTO, Professor Avishai Wool, presented a technical webinar on the do’s and don’ts for managing external connectivity to and from your network . We kicked off our webinar by polling the audience (186 people) on how many external permanent connections into their enterprise network they have. 40% have less than 50 external connections 31% have 50-250 external connections 24% have more than 250 external connections 5% wish they knew how many external connections they have! Clearly this is a very relevant issue for many enterprises, and one which can have a profound effect on security. The webinar covered a wide range of best practices for managing the external connectivity lifecycle and I highly recommend that you view the full presentation. But in the meantime, here are a few key issues that you should be mindful of when considering how to manage external connectivity to and from your network: Network Segmentation While there has to be an element of trust when you let an external partner into your network, you must do all you can to protect your organization from attacks through these connections. These include placing your servers in a demilitarized zone (DMZ), segregating them by firewalls, restricting traffic in both directions from the DMZ as well as using additional controls such as web application firewalls, data leak prevention and intrusion detection. Regulatory Compliance Bear in mind that if the data being accessed over the external connection is regulated, both your systems and the related peer’s systems are now subject t. So if the network connection touches credit card data, both sides of the connection are in scope, and outsourcing the processing and management of regulated data to a partner does not let you off the hook. Maintenance Sometimes you will have to make changes to your external connections, either due to planned maintenance work by your IT team or the peer’s team, or as a result of unplanned outages. Dealing with changes that affect external connections is more complicated than internal maintenance, as it will probably require coordinating with people outside your organisation and tweaking existing workflows, while adhering to any contractual or SLA obligations. As part of this process, remember that you’ll need to ensure that your information systems allow your IT teams to recognize external connections and provide access to the relevant technical information in the contract, while supporting the amended workflows. Contracts In most cases there is a contract that governs all aspects of the external connection – including technical and business issues. The technical points will include issues such as IP addresses and ports, technical contact points, SLAs, testing procedures and the physical location of servers. It’s important, therefore, that this contract is adhered to whenever dealing with technical issues related to external connections. These are just a few tips and issues to be aware of.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 11/25/21 Published Nick Ellsmore is an Australian cybersecurity professional whose thoughts on the future of cybersecurity are always insightful. Having a deep respect for Nick, I really enjoyed listening to his latest podcast “Episode 79 Making the cyber sector redundant with Nick Ellsmore” . As Nick opened the door to debate on “all the mildly controversial views” he has put forward in the podcast, I decided to take a stab at a couple of points made by Nick. For some mysterious reason, these points have touched my nerve. So, here we go. Nick: The cybersecurity industry, we spent so long trying to get people to listen to us and take the issue seriously, you know, we’re now getting that, you know. Are the businesses really responding because we were trying to get people to listen to us? Let me rephrase this question. Are the businesses really spending more on cybersecurity because we were trying to get people to listen to us? The “cynical me” tells me No. Businesses are spending more on cybersecurity because they are losing more due to cyber incidents. It’s not the number of incidents; it’s their impact that is increasingly becoming devastating. Over the last ten years, there were plenty of front-page headliners that shattered even seemingly unshakable businesses and government bodies. Think of Target attack in 2013, the Bank of Bangladesh heist in 2016, Equifax breach in 2017, SolarWinds hack in 2020 .. the list goes on. We all know how Uber tried to bribe attackers to sweep the stolen customer data under the rug. But how many companies have succeeded in doing so without being caught? How many cyber incidents have never been disclosed? These headliners don’t stop. Each of them is another reputational blow, impacted stock options, rolled heads, stressed-out PR teams trying to play down the issue, knee-jerk reaction to acquire snake-oil-selling startups, etc. We’re not even talking about skewed election results (a topic for another discussion). Each one of them comes at a considerable cost. So no wonder many geniuses now realise that spending on cybersecurity can actually mitigate those risks. It’s not our perseverance that finally started paying off. It’s their pockets that started hurting. Nick: I think it’s important that we don’t lose sight of the fact that this is actually a bad thing to have to spend money on. Like, the reason that we’re doing this is not healthy. .. no one gets up in the morning and says, wow, I can’t wait to, you know, put better locks on my doors. It’s not the locks we sell. We sell gym membership. We want people to do something now to stop bad things from happening in the future. It’s a concept of hygiene, insurance, prevention, health checks. People are free not to pursue these steps, and run their business the way they used to .. until they get hacked, get into the front page, wondering first “Why me?” and then appointing a scapegoat. Nick: And so I think we need to remember that, in a sense, our job is to create the entire redundancy of this sector. Like, if we actually do our job, well, then we all have to go and do something else, because security is no longer an issue. It won’t happen due to 2 main reasons. Émile Durkheim believed in a “society of saints”. Unfortunately, it is a utopia. Greed, hunger, jealousy, poverty are the never-ending satellites of the human race that will constantly fuel crime. Some of them are induced by wars, some — by corrupt regimes, some — by sanctions, some — by imperfect laws. But in the end — there will always be Haves and Have Nots, and therefore, fundamental inequality. And that will feed crime. “Errare humanum est” , Seneca. To err is human. Because of human errors, there will always be vulnerabilities in code. Because of human nature (and as its derivative, geopolitical or religious tension, domination, competition, nationalism, fight for resources), there will always be people willing to and capable of exploiting those vulnerabilities. Mix those two ingredients — and you get a perfect recipe for cybercrime. Multiply that with never-ending computerisation, automation, digital transformation, and you get a constantly growing attack surface. No matter how well we do our job, we can only control cybercrime and keep the lid on it, but we can’t eradicate it. Thinking we could would be utopic. Another important consideration here is budget constraints. Building proper security is never fun — it’s a tedious process that burns cash but produces no tangible outcome. Imagine a project with an allocated budget B to build a product P with a feature set F, in a timeframe T. Quite often, such a project will be underfinanced, potentially leading to a poor choice of coders, overcommitted promises, unrealistic expectations. Eventually leading to this (oldie, but goldie): Add cybersecurity to this picture, and you’ll get an extra step that seemingly complicates everything even further: The project investors will undoubtedly question why that extra step was needed. Is there a new feature that no one else has? Is there a unique solution to an old problem? None of that? Then what’s the justification for such over-complication? Planning for proper cybersecurity built-in is often perceived as FUD. If it’s not tangible, why do we need it? Customers won’t see it. No one will see it. Scary stories in the press? Nah, that’ll never happen to us. In some way, extra budgeting for cybersecurity is anti-capitalistic in nature. It increases the product cost and, therefore, its price, making it less competitive. It defeats the purpose of outsourcing product development, often making outsourcing impossible. From the business point of view, putting “Sec” into “DevOps” does not make sense. That’s Ok. No need. .. until it all gloriously hits the fan, and then we go back to STEP 1. Then, maybe, just maybe, the customer will say, “If we have budgeted for that extra step, then maybe we would have been better off”.

Learn how firewall rules secure your network from cyber threats. Explore types, best practices, and management strategies to optimize your firewall security. Firewall rules & requirements (inbound vs. outbound) How to secure your network from threats? The cybersecurity landscape is increasingly volatile, with a massive rise in cyberattacks. Malicious cyber actors are relentlessly scouring the internet for vulnerable networks. Any company that wants to keep its network secure must implement a network security solution – a firewall. Cyber attackers keep evolving and finding ways to compromise security systems. As a result, companies need to implement and maintain security best practices. Installing a firewall is not enough; you have to take a step further to ensure the firewall rules are up-to-date and properly managed. If you want to learn how firewall rules work and secure your network from threats, keep reading! This article covers everything you need to know, including types of firewall rules, examples of firewall rules, and firewall rule best practices. Schedule a Demo What are firewall rules? Firewall rules are the major components of firewall policies that determine which types of traffic your firewall allows in and out of your network, and which are blocked. They are access control mechanisms that firewalls use to protect your network from being infiltrated by malicious or unauthorized traffic. Firewall rules examine the control information in individual packets, and either block or allow them based on a set of rules or predetermined criteria. These predetermined criteria or rule components include a source IP address, a destination IP address, ports, protocol type (TCP, UDP, or ICMP), and services. Firewall rules control how the firewalls prevent malicious programs and unauthorized traffic from compromising your network. So properly managing your firewall rules across your infrastructures is instrumental to securing your network from threats. Schedule a Demo How do firewall rules work? A firewall examines each incoming and outgoing data packet and matches it against the firewall rules. A packet is allowed to go through to its destination if it matches one of the rules that allow traffic. If a packet matches none of the rulesor hit a rule with deny, it is rejected. The rejection or mismatch is reported if the firewall is configured to do so. Firewalls are programmed to work with access control lists (ACLs). ACLs contain lists of permissions that determine network traffic that is allowed or blocked. An access control list details the conditions a data packet must meet before the ACL action (allow, deny, or reject) can be executed. To help you understand how firewall rules work, here’s a practical example: if a firewall rule states that traffic to destination N should be allowed only if it is from IP address M, the firewall will check the packet source and destination of incoming packets, and allow packets that meet the M & N rule to go through. If its packet’s destination is N but its source is unidentified or different from M, it is blocked. Packets are checked against firewall rules from top to bottom, and the first rule that matches the packet overrides the other rules below. The last rule is Deny Rest. This means that all packets not expressly permitted by the rules are blocked. You can create a firewall rule in pfSense. pfSense is an open-source firewall and router with unified threat management, load balancing, multi-WAN, a DNS Resolver, and a VPN. It supports a wide range of network technologies, including IPv4 & IPv6 addresses and pfBlockerNG. Other firewalls you can use to create firewall rules include Zenarmor, Windows Defender, and iptables. Schedule a Demo Why are firewall rules important? Firewall rules help network administrators to regulate access to networks. With firewall rules, you can determine what is allowed in and out of your network. For example, they prevent dangerous files like worms and viruses from accessing your network and consuming bandwidth. When it comes to protecting devices that operate within your network, firewall rules establish an essential line of defense. Firewalls (and other security measures like endpoint protection and security certifications) prevent malicious actors from accessing and compromising devices connected to your network or operating inside your network’s environment. Firewall rules help you comply with regulatory standards. Depending on your industry, relevant regulatory agencies expect your company to maintain a certain level of security. For example, if your business is located in the EU region or collects personal data of EU citizens, it is mandated to comply with GDPR. Schedule a Demo What are the main types of firewall rules? There are various types of firewall rules. They are categorized based on the type of security architecture under consideration. That being said, here are some of the major types of firewall rules: 1. Access rule As the name implies, this firewall rule blocks or grants access to inbound and outbound traffic based on certain conditions. The source address, destination address, port number, and protocol are key information that the access rule evaluates to determine whether access should be given or denied. 2. Network address translation (NAT) rule NAT helps you hide the original IP address of a private network – enabling you to protect your network. It makes traffic routing easier and smoothens the inflow & outflow of traffic to and from your network. 3. Application level gateways This type of firewall rule enables network administrators to implement policies that protect your internal network. Application-level gateways function as shields or gatekeepers between your internal network and the public internet. Administrators use them to regulate access to public networks, block some sites, limit access to certain content, and regulate devices allowed to access your network. 4. Stateful packet filtering This rule evaluates data packets and filters them against preset conditions. The traffic is denied access if it fails to meet the requirements outlined by the predetermined security criteria. 5. Circle-level gateways Circle-level gateways do not filter individual packets but rather monitor TCP handshakes to determine whether a session is legitimate and the remote system is considered trusted. Consequently, these gateways provide anonymity to your internal network. Schedule a Demo What is an example of a firewall rule? Firewall rules frequently consist of a source address, source port, destination address, destination port, and an action that determines whether to Allow or Deny the packet. In the following firewall ruleset example, the firewall is never directly accessed from the public network. This is because hackers who can directly access the firewall, can modify or delete rules and allow unwanted travel. Source addressSource portDestination addressDestination portAction AnyAny10.10.10.1AnyDenyAnyAny10.10.10.2AnyDeny10.10.10.1AnyAnyAnyDeny10.10.10.2AnyAnyAnyDeny In the following firewall ruleset example, all traffic from the trusted network is allowed out. This ruleset should be placed below the ruleset above. Since firewall rules are checked from top to bottom, specific rules should be placed before rules that are more general. Source addressSource portDestination addressDestination portAction 10.10.10.0AnyAnyAnyAllow Schedule a Demo What are the best ways to manage firewall rules? Effective management of firewall rules is necessary to avoid conflicting configurations and ensure your security infrastructure is powerful enough to ward off malicious attacks. To manage firewall rules better, do the following: ● Maintain proper documentation Properly document policies, rules, and workflows. It’s difficult for your network administrators to stay organized and manage firewall rules without proper documentation. Implement a strict documentation policy that mandates administrators to document policies and configuration changes. This improves visibility and ensures seamless continuity even if a key network operator leaves the company. ● Assign tasks with caution Ensure that only well-trained network operators have the privilege to assign and alter firewall rules. Allowing everyone on your security team to assign and change firewall rules increases the chances of misconfiguration. Giving such a privilege to a select few does the opposite and makes containing mismanagement easier. ● Use a standardized naming convention It’s easy to get confused about which configuration does what. This is more likely to happen where there is no naming convention. To avoid conflicting configurations, name each rule to clarify its purpose. By clearly defining the rules, conflicts can be easily resolved. ● Flag temporary rules Some rules are created to function just for a while – temporary rules. To keep things simple and ‘neat,’ flag temporary rules so they can be eliminated when they are no longer required. ● Order your rules Order rules in a specific pattern. For example, begin with global rules and narrow down to user-specific rules. ● Use a firewall management solution Many administrators use a firewall management and orchestration solution to streamline the firewall rule management process. The solution integrates with your firewall and uses built-in automation for managing firewall settings and configurations from a single dashboard. A firewall management tool helps you automate activities, gain visibility on all firewall rules, optimize firewall rules, remove rule anomalies, generate reports, etc. Schedule a Demo What are the best practices for firewall rules? To ensure your firewall works properly and offers the best security possible, there are some key best practices you have to follow when configuring and managing firewall rules: Review the firewall rules regularly The cyber threat landscape is always changing. Therefore, you must regularly review the firewall rules to ensure they provide optimal security against threats. Reviewing firewall rules helps you to be several steps ahead of malicious cyber actors, remove rule anomalies, and maintain compliance. Cyber attackers are relentlessly devising new ways to compromise security systems, infiltrate networks & subnets, and wreak havoc. You need to update the firewall rules regularly to counter new attacks. Obsolete rules can be maneuvered and the firewall compromised. You have to keep evolving the rules to stay ahead of malicious actors. Remove ineffective, redundant firewall rules. Are there rules that are no longer needed? Are there overlapping rules that are taking up space and confusing your network administrators? Look out for unnecessary configurations and remove them to free up the system and avoid confusion. In addition to helping you keep your network safe, reviewing firewall rules regularly also allows you to maintain compliance with regulatory standards such as HIPAA and GDPR. Keep tabs on firewall logs Keeping an eye on the firewall log helps administrators to monitor traffic flow, identify suspicious activities, and proactively fix challenges. Monitoring firewall logs gives you visibility into your infrastructure, enabling you to get to know your network users and the nature of their activities. Reduce complexity by categorizing firewall rules Make firewall rule structure simple and easy to manage by grouping rules with similar characteristics. This approach reduces configuration complexity, improves ease of administration, and optimizes firewall performance. Implement least-privileged access Do not grant users more privileges than necessary to perform their tasks. This ensures that only an authorized user can create a new rule, change a security policy, or gain access to specific resources. Block high-risk ports Blocking some ports can significantly decrease the risk of a network breach. The following table outlines the ports you should block as recommended by the SANS Institute . The table features services, TCP port, UDP port, port number, and port range.

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.
