Tags Share this article 8/28/23 Published Like all modern cloud providers, Amazon adopts the shared responsibility model for cloud security. Amazon guarantees secure infrastructure for Amazon Web Services, while AWS users are responsible for maintaining secure configurations. That requires using multiple AWS services and tools to manage traffic. You’ll need to develop a set of inbound rules for incoming connections between your Amazon Virtual Private Cloud (VPC) and all of its Elastic Compute (EC2) instances and the rest of the Internet. You’ll also need to manage outbound traffic with a series of outbound rules. Your Amazon VPC provides you with several tools to do this. The two most important ones are security groups and Network Access Control Lists (NACLs). Security groups are stateful firewalls that secure inbound traffic for individual EC2 instances. Network ACLs are stateless firewalls that secure inbound and outbound traffic for VPC subnets. Managing AWS VPC security requires configuring both of these tools appropriately for your unique security risk profile. This means planning your security architecture carefully to align it the rest of your security framework. For example, your firewall rules impact the way Amazon Identity Access Management (IAM) handles user permissions. Some (but not all) IAM features can be implemented at the network firewall layer of security. Before you can manage AWS network security effectively , you must familiarize yourself with how AWS security tools work and what sets them apart. Everything you need to know about security groups vs NACLs AWS security groups explained: Every AWS account has a single default security group assigned to the default VPC in every Region. It is configured to allow inbound traffic from network interfaces assigned to the same group, using any protocol and any port. It also allows all outbound traffic using any protocol and any port. Your default security group will also allow all outbound IPv6 traffic once your VPC is associated with an IPv6 CIDR block. You can’t delete the default security group, but you can create new security groups and assign them to AWS EC2 instances. Each security group can only contain up to 60 rules, but you can set up to 2500 security groups per Region. You can associate many different security groups to a single instance, potentially combining hundreds of rules. These are all allow rules that allow traffic to flow according the ports and protocols specified. For example, you might set up a rule that authorizes inbound traffic over IPv6 for linux SSH commands and sends it to a specific destination. This could be different from the destination you set for other TCP traffic. Security groups are stateful, which means that requests sent from your instance will be allowed to flow regardless of inbound traffic rules. Similarly, VPC security groups automatically responses to inbound traffic to flow out regardless of outbound rules. However, since security groups do not support deny rules, you can’t use them to block a specific IP address from connecting with your EC2 instance. Be aware that Amazon EC2 automatically blocks email traffic on port 25 by default – but this is not included as a specific rule in your default security group. AWS NACLs explained: Your VPC comes with a default NACL configured to automatically allow all inbound and outbound network traffic. Unlike security groups, NACLs filter traffic at the subnet level. That means that Network ACL rules apply to every EC2 instance in the subnet, allowing users to manage AWS resources more efficiently. Every subnet in your VPC must be associated with a Network ACL. Any single Network ACL can be associated with multiple subnets, but each subnet can only be assigned to one Network ACL at a time. Every rule has its own rule number, and Amazon evaluates rules in ascending order. The most important characteristic of NACL rules is that they can deny traffic. Amazon evaluates these rules when traffic enters or leaves the subnet – not while it moves within the subnet. You can access more granular data on data flows using VPC flow logs. Since Amazon evaluates NACL rules in ascending order, make sure that you place deny rules earlier in the table than rules that allow traffic to multiple ports. You will also have to create specific rules for IPv4 and IPv6 traffic – AWS treats these as two distinct types of traffic, so rules that apply to one do not automatically apply to the other. Once you start customizing NACLs, you will have to take into account the way they interact with other AWS services. For example, Elastic Load Balancing won’t work if your NACL contains a deny rule excluding traffic from 0.0.0.0/0 or the subnet’s CIDR. You should create specific inclusions for services like Elastic Load Balancing, AWS Lambda, and AWS CloudWatch. You may need to set up specific inclusions for third-party APIs, as well. You can create these inclusions by specifying ephemeral port ranges that correspond to the services you want to allow. For example, NAT gateways use ports 1024 to 65535. This is the same range covered by AWS Lambda functions, but it’s different than the range used by Windows operating systems. When creating these rules, remember that unlike security groups, NACLs are stateless. That means that when responses to allowed traffic are generated, those responses are subject to NACL rules. Misconfigured NACLs deny traffic responses that should be allowed, leading to errors, reduced visibility, and potential security vulnerabilities . How to configure and map NACL associations A major part of optimizing NACL architecture involves mapping the associations between security groups and NACLs. Ideally, you want to enforce a specific set of rules at the subnet level using NACLs, and a different set of instance-specific rules at the security group level. Keeping these rulesets separate will prevent you from setting inconsistent rules and accidentally causing unpredictable performance problems. The first step in mapping NACL associations is using the Amazon VPC console to find out which NACL is associated with a particular subnet. Since NACLs can be associated with multiple subnets, you will want to create a comprehensive list of every association and the rules they contain. To find out which NACL is associated with a subnet: Open the Amazon VPC console . Select Subnets in the navigation pane. Select the subnet you want to inspect. The Network ACL tab will display the ID of the ACL associated with that network, and the rules it contains. To find out which subnets are associated with a NACL: Open the Amazon VPC console . Select Network ACLS in the navigation pane. Click over to the column entitled Associated With. Select a Network ACL from the list. Look for Subnet associations on the details pane and click on it. The pane will show you all subnets associated with the selected Network ACL. Now that you know how the difference between security groups and NACLs and you can map the associations between your subnets and NACLs, you’re ready to implement some security best practices that will help you strengthen and simplify your network architecture. 5 best practices for AWS NACL management Pay close attention to default NACLs, especially at the beginning Since every VPC comes with a default NACL, many AWS users jump straight into configuring their VPC and creating subnets, leaving NACL configuration for later. The problem here is that every subnet associated with your VPC will inherit the default NACL. This allows all traffic to flow into and out of the network. Going back and building a working security policy framework will be difficult and complicated – especially if adjustments are still being made to your subnet-level architecture. Taking time to create custom NACLs and assign them to the appropriate subnets as you go will make it much easier to keep track of changes to your security posture as you modify your VPC moving forward. Implement a two-tiered system where NACLs and security groups complement one another Security groups and NACLs are designed to complement one another, yet not every AWS VPC user configures their security policies accordingly. Mapping out your assets can help you identify exactly what kind of rules need to be put in place, and may help you determine which tool is the best one for each particular case. For example, imagine you have a two-tiered web application with web servers in one security group and a database in another. You could establish inbound NACL rules that allow external connections to your web servers from anywhere in the world (enabling port 443 connections) while strictly limiting access to your database (by only allowing port 3306 connections for MySQL). Look out for ineffective, redundant, and misconfigured deny rules Amazon recommends placing deny rules first in the sequential list of rules that your NACL enforces. Since you’re likely to enforce multiple deny rules per NACL (and multiple NACLs throughout your VPC), you’ll want to pay close attention to the order of those rules, looking for conflicts and misconfigurations that will impact your security posture. Similarly, you should pay close attention to the way security group rules interact with your NACLs. Even misconfigurations that are harmless from a security perspective may end up impacting the performance of your instance, or causing other problems. Regularly reviewing your rules is a good way to prevent these mistakes from occurring. Limit outbound traffic to the required ports or port ranges When creating a new NACL, you have the ability to apply inbound or outbound restrictions. There may be cases where you want to set outbound rules that allow traffic from all ports. Be careful, though. This may introduce vulnerabilities into your security posture. It’s better to limit access to the required ports, or to specify the corresponding port range for outbound rules. This establishes the principle of least privilege to outbound traffic and limits the risk of unauthorized access that may occur at the subnet level. Test your security posture frequently and verify the results How do you know if your particular combination of security groups and NACLs is optimal? Testing your architecture is a vital step towards making sure you haven’t left out any glaring vulnerabilities. It also gives you a good opportunity to address misconfiguration risks. This doesn’t always mean actively running penetration tests with experienced red team consultants, although that’s a valuable way to ensure best-in-class security. It also means taking time to validate your rules by running small tests with an external device. Consider using AWS flow logs to trace the way your rules direct traffic and using that data to improve your work. How to diagnose security group rules and NACL rules with flow logs Flow logs allow you to verify whether your firewall rules follow security best practices effectively. You can follow data ingress and egress and observe how data interacts with your AWS security rule architecture at each step along the way. This gives you clear visibility into how efficient your route tables are, and may help you configure your internet gateways for optimal performance. Before you can use the Flow Log CLI, you will need to create an IAM role that includes a policy granting users the permission to create, configure, and delete flow logs. Flow logs are available at three distinct levels, each accessible through its own console: Network interfaces VPCs Subnets You can use the ping command from an external device to test the way your instance’s security group and NACLs interact. Your security group rules (which are stateful) will allow the response ping from your instance to go through. Your NACL rules (which are stateless) will not allow the outbound ping response to travel back to your device. You can look for this activity through a flow log query. Here is a quick tutorial on how to create a flow log query to check your AWS security policies. First you’ll need to create a flow log in the AWS CLI. This is an example of a flow log query that captures all rejected traffic for a specified network interface. It delivers the flow logs to a CloudWatch log group with permissions specified in the IAM role: aws ec2 create-flow-logs \ –resource-type NetworkInterface \ –resource-ids eni-1235b8ca123456789 \ –traffic-type ALL \ –log-group-name my-flow-logs \ –deliver-logs-permission-arn arn:aws:iam::123456789101:role/publishFlowLogs Assuming your test pings represent the only traffic flowing between your external device and EC2 instance, you’ll get two records that look like this: 2 123456789010 eni-1235b8ca123456789 203.0.113.12 172.31.16.139 0 0 1 4 336 1432917027 1432917142 ACCEPT OK 2 123456789010 eni-1235b8ca123456789 172.31.16.139 203.0.113.12 0 0 1 4 336 1432917094 1432917142 REJECT OK To parse this data, you’ll need to familiarize yourself with flow log syntax. Default flow log records contain 14 arguments, although you can also expand custom queries to return more than double that number: Version tells you the version currently in use. Default flow logs requests use Version 2. Expanded custom requests may use Version 3 or 4. Account-id tells you the account ID of the owner of the network interface that traffic is traveling through. The record may display as unknown if the network interface is part of an AWS service like a Network Load Balancer. Interface-id shows the unique ID of the network interface for the traffic currently under inspection. Srcaddr shows the source of incoming traffic, or the address of the network interface for outgoing traffic. In the case of IPv4 addresses for network interfaces, it is always its private IPv4 address. Dstaddr shows the destination of outgoing traffic, or the address of the network interface for incoming traffic. In the case of IPv4 addresses for network interfaces, it is always its private IPv4 address. Srcport is the source port for the traffic under inspection. Dstport is the destination port for the traffic under inspection. Protocol refers to the corresponding IANA traffic protocol number . Packets describes the number of packets transferred. Bytes describes the number of bytes transferred. Start shows the start time when the first data packet was received. This could be up to one minute after the network interface transmitted or received the packet. End shows the time when the last data packet was received. This can be up to one minutes after the network interface transmitted or received the data packet. Action describes what happened to the traffic under inspection: ACCEPT means that traffic was allowed to pass. REJECT means the traffic was blocked, typically by security groups or NACLs. Log-status confirms the status of the flow log: OK means data is logging normally. NODATA means no network traffic to or from the network interface was detected during the specified interval. SKIPDATA means some flow log records are missing, usually due to internal capacity restraints or other errors. Going back to the example above, the flow log output shows that a user sent a command from a device with the IP address 203.0.113.12 to the network interface’s private IP address, which is 172.31.16.139. The security group’s inbound rules allowed the ICMP traffic to travel through, producing an ACCEPT record. However, the NACL did not let the ping response go through, because it is stateless. This generated the REJECT record that followed immediately after. If you configure your NACL to permit output ICMP traffic and run this test again, the second flow log record will change to ACCEPT. azon Web Services (AWS) is one of the most popular options for organizations looking to migrate their business applications to the cloud. It’s easy to see why: AWS offers high capacity, scalable and cost-effective storage, and a flexible, shared responsibility approach to security. Essentially, AWS secures the infrastructure, and you secure whatever you run on that infrastructure. However, this model does throw up some challenges. What exactly do you have control over? How can you customize your AWS infrastructure so that it isn’t just secure today, but will continue delivering robust, easily managed security in the future? The basics: security groups AWS offers virtual firewalls to organizations, for filtering traffic that crosses their cloud network segments. The AWS firewalls are managed using a concept called Security Groups. These are the policies, or lists of security rules, applied to an instance – a virtualized computer in the AWS estate. AWS Security Groups are not identical to traditional firewalls, and they have some unique characteristics and functionality that you should be aware of, and we’ve discussed them in detail in video lesson 1: the fundamentals of AWS Security Groups , but the crucial points to be aware of are as follows. First, security groups do not deny traffic – that is, all the rules in security groups are positive, and allow traffic. Second, while security group rules can be set to specify a traffic source, or a destination, they cannot specify both on the same rule. This is because AWS always sets the unspecified side (source or destination) as the instance to which the group is applied. Finally, single security groups can be applied to multiple instances, or multiple security groups can be applied to a single instance: AWS is very flexible. This flexibility is one of the unique benefits of AWS, allowing organizations to build bespoke security policies across different functions and even operating systems, mixing and matching them to suit their needs. Adding Network ACLs into the mix To further enhance and enrich its security filtering capabilities AWS also offers a feature called Network Access Control Lists (NACLs). Like security groups, each NACL is a list of rules, but there are two important differences between NACLs and security groups. The first difference is that NACLs are not directly tied to instances, but are tied with the subnet within your AWS virtual private cloud that contains the relevant instance. This means that the rules in a NACL apply to all of the instances within the subnet, in addition to all the rules from the security groups. So a specific instance inherits all the rules from the security groups associated with it, plus the rules associated with a NACL which is optionally associated with a subnet containing that instance. As a result NACLs have a broader reach, and affect more instances than a security group does. The second difference is that NACLs can be written to include an explicit action, so you can write ‘deny’ rules – for example to block traffic from a particular set of IP addresses which are known to be compromised. The ability to write ‘deny’ actions is a crucial part of NACL functionality. It’s all about the order As a consequence, when you have the ability to write both ‘allow’ rules and ‘deny’ rules, the order of the rules now becomes important. If you switch the order of the rules between a ‘deny’ and ‘allow’ rule, then you’re potentially changing your filtering policy quite dramatically. To manage this, AWS uses the concept of a ‘rule number’ within each NACL. By specifying the rule number, you can identify the correct order of the rules for your needs. You can choose which traffic you deny at the outset, and which you then actively allow. As such, with NACLs you can manage security tasks in a way that you cannot do with security groups alone. However, we did point out earlier that an instance inherits security rules from both the security groups, and from the NACLs – so how do these interact? The order by which rules are evaluated is this; For inbound traffic, AWS’s infrastructure first assesses the NACL rules. If traffic gets through the NACL, then all the security groups that are associated with that specific instance are evaluated, and the order in which this happens within and among the security groups is unimportant because they are all ‘allow’ rules. For outbound traffic, this order is reversed: the traffic is first evaluated against the security groups, and then finally against the NACL that is associated with the relevant subnet.

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.

Cloud environments are complex and dynamic. Due to the complexity and multifacetedness of cloud technologies, cloud-native applications... Cloud Security What is a Cloud-Native Application Protection Platform (CNAPP) Ava Chawla 2 min read Ava Chawla 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 Cloud environments are complex and dynamic. Due to the complexity and multifacetedness of cloud technologies, cloud-native applications are challenging to safeguard. As a result, security teams use multiple security solutions, like CWPP and CSPM, to protect applications. The problem with this approach is that handling multiple security tools is laborious, time-consuming, and inefficient. Cloud-native application protection platform (CNAPP) is a new cloud security solution that promises to solve this problem. What is CNAPP? A cloud-native application protection platform (CNAPP) is an all-in-one tool with the capabilities of different cloud-native security tools. It combines the security features of multiple tools and provides comprehensive protection – from the development and configuration stages to deployment and runtime. Container security is here to stay A CNAPP combines CSPM, CIEM, IAM, CWPP, and more in one tool. It streamlines cloud security monitoring, threat detection, and remediation processes. The all-in-one platform gives organizations better visibility into threats and vulnerabilities. Instead of using multiple tools to receive alerts and formulate a remediation plan, a CNAPP minimizes complexity and enables security teams to monitor and draw insights from a single platform. How Does CNAPP Work and Why is it So Important to Have? This new cloud security approach offers the capabilities of multiple security tools in one software. Some of these security functions include Cloud Security Posture Management (CSPM), Infrastructure-as-Code (IaC) Scanning, Cloud Workload Protection Platform (CWPP), Cloud Network Security Connectivity (CNSC), and Kubernetes Security Posture Management (CIEM). The all-in-one platform centralizes insights, enabling security professionals to monitor and analyze data from the same space. A CNAPP identifies risks with strong context, provides detailed alerts, and offers automation features to fix vulnerabilities and misconfigurations. A CNAPP is essential because it reduces complexity and minimizes overhead. Given how complex and dynamic the cloud environments are, organizations are faced with enormous security threats. Enterprises deploy applications on multiple private and public clouds leveraging various dynamic, mixed technologies. This makes securing cloud assets significantly challenging. To cope with the complexity, security operations teams rely on multiple cloud security solutions. SecOps use various solutions to protect modern development practices, such as containers, Kubernetes, serverless functions, CI/CD pipelines, and infrastructure as code (IaC). This approach has been helpful. That said, it’s laborious and inefficient. In addition to not providing a broad view of security risks, dealing with multiple tools negatively impacts accuracy and decreases productivity. Having to correlate data from several platforms leads to errors and delayed responses. A CNAPP takes care of these problems by combining the functionalities of multiple tools in one software. It protects every stage of the cloud application lifecycle, from development to runtime. Leveraging advanced analytics and remediation automation, CNAPPs help organizations address cloud-native risks, harden applications, and institute security best practices. What Problems Does a CNAPP Solve? This new category of cloud application security tool is revolutionizing the cybersecurity landscape. It solves major challenges DevSecOps have been dealing with. That said, a CNAPP helps security teams to solve the following problems. 1. Enhancing Visibility and Quantifying Risks A CNAPP offers a broader visibility of security risks. It leverages multiple security capabilities to enable DevOps and DevSecOps to spot and fix potential security issues throughout the entire application lifecycle. The all-in-one security platform enables teams to keep tabs on all cloud infrastructures ( like apps, APIs, and classified data) and cloud services (like AWS, Azure, and Google Cloud). In addition, it provides insights that help security teams to quantify risks and formulate data-driven remediation strategies. 2. Combined Cloud Security Solution A CNAPP eliminates the need to use multiple cloud-native application protection solutions. It provides all the features needed to detect and solve security issues. Scanning, detection, notification, and reporting are consolidated in one software. This reduces human error, shortens response time, and minimizes the cost of operation. 3. Secure Software Development It reinforces security at every stage of the application lifecycle. The tool helps DevOps teams to shift left, thus minimizing the incidence of vulnerabilities or security issues at runtime. 4. Team Collaboration Collaboration is difficult and error-prone when teams are using multiple tools. Data correlation and analysis take more time since team members have more than one tool to deal with. A CNAPP is a game-changer! It has advanced workflows, data correlation, analytics, and remediation features. These functionalities enhance team collaboration and increase productivity. What are CNAPP Features and Capabilities/Key Components of CNAPP? Even though the features and capabilities of CNAPPs differ (based on vendors), there are key components an effective CNAPP should have. That being said, here are the seven key components: Cloud Security Posture Management (CSPM) A CSPM solution focuses on maintaining proper cloud configuration. It monitors, detects, and fixes misconfigurations & compliance violations. CSPM monitors cloud resources and alerts security teams when a non-compliant resource is identified. Infrastructure-as-Code (IaC) Scanning IaC Scanning enables the early detection of errors (misconfigurations) in code. Spotting misconfigurations before deployment helps to avoid vulnerabilities at runtime. This tool is used to carry out some kind of code review. The purpose is to ensure code quality by scanning for vulnerable points, compliance issues, and violations of policies. Cloud Workload Protection Platform (CWPP) Cloud workload protection platform (CSPM) secures cloud workloads, shielding your resources from security threats. CSPM protects various workloads, from virtual machines (VMs) and databases to Kubernetes and containers. A CWPP monitors and provides insights to help security teams prevent security breaches. Cloud Network Security Connectivity (CNSC) Cloud Network Security Connectivity (CNSC) provides complete real-time visibility and access to risks across all your cloud resources and accounts. This cloud security solution allows you to explore the risks, activate security rules, and suppress whole risks or risk triggers, export risk trigger details, access all network rules in the context of their policy sets and create risk reports. Kubernetes Security Posture Management (KSPM) Kubernetes security posture management (KSPM) capability enables organizations to maintain standard security posture by preventing Kubernetes misconfigurations and compliance violations. KSPM solution, similar to Cloud Security Posture Management (CSPM), automates Kubernetes security, reinforces compliance, identifies misconfigurations, and monitors Kubernetes clusters to ensure maximum security. Cloud Infrastructure Entitlement Management (CIEM) A Cloud Infrastructure Entitlement Management (CIEM) tool is used to administer permissions and access policies. To maintain the integrity of cloud and multi-cloud environments, identities and access privileges must be regulated. This is where CIEM comes in! CIEM solutions, also known as Cloud permissions Management Solutions, help organizations prevent data breaches by enforcing the principle of least privileges. Integration to Software Development Activities This component of CNAPP focuses on integrating cloud-native application protection solutions into the development phase to improve reliability and robustness in the CI/CD pipeline stage. What are the Benefits of CNAPP? Transitioning from using multiple cloud security tools to implementing a CNAPP solution can benefit your company in many ways. Some benefits include: 1. Streamlines Security Operations Managing multiple security tools decreases efficiency and leads to employee burnout. Correlating data from different software is laborious and error-prone. It prolongs response time. A CNAPP streamlines activities by giving security teams broad visibility from a single tool. This makes monitoring and remediation easier than ever – making security teams more efficient and productive. 2. Better Visibility into Risks A CNAPP provides better visibility into security risks associated with your cloud infrastructure. It covers all aspects of cloud-native application protection, providing security teams with the necessary insights to close security gaps, harden applications, and ward off threats. 3. Improves Security With Automation Risk detection and vulnerability management are automated.

Horizon Horizon FireFlow zero-touch change management integrates strategy, planning and design, implementing proactive risk analysis, validation and auditing to prevent errors and save time. How can I manage my firewall security policy? Firewall change requests are requests for a firewall configuration change which result in a change to the network security infrastructure. Firewall change requests must be monitored to prevent unintentional errors that violate compliance standards or increase vulnerabilities to the network. What are firewall change requests? Firewall policy rules determine what traffic your firewall allows and what is blocked. Firewall rules examine the control information in individual packets, and either block or allow them according to the criteria that you define. Firewall rules control how the firewalls protect your network from malicious programs and unauthorized access. What are firewall policy rules? When making changes to firewall rules, be aware of any potential security risks. Firewall rules should always be documented, with the creation and expiration date, the name of the person who added the rule and clarification of the rule’s purpose and what applications, services, devices, users and data it affects.
