Firewalls Ablaze? Put Out Network Security Audit & Compliance Fires

Tal Dayan
Product Manager

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. By adopting these best practices, security teams will significantly improve their network’s security posture and reduce the pain of ensuring compliance with regulations, industry standards and corporate policies.

AlgoSec AppViz - Application Visibility For AlgoSec Firewall Analyzer

On any given day, new business applications are added, changed or removed, which requires the implementation of complex, time-consuming network security changes. Migrating business applications to the cloud adds additional complexities, such as understanding the network connectivity of each application prior to deployment, provisioning the relevant firewalls and routers in the cloud, and then migrating and adjusting existing network connectivity to support them. Moreover, for each business application to run smoothly, all teams within the IT organization need to collaborate, align, and communicate their needs in a common language. To achieve this, an application-centric approach to security policy management is needed.

It provides full visibility of your network security environment, including firewalls and the firewall rules that determine network traffic. This facilitates a deep understanding of the implications of any planned changes to application connectivity and how to configure the firewalls appropriately with these changes.

Enhance Compliance

Having full knowledge of all business applications aids the company in their adherence to different compliance requirements. For example, PCI DSS requires customers to audit all the applications that fall within the scope of the regulation. This informa- tion is easy to determine through application network connectivity mapping.

Accelerate Troubleshooting

Application network connectivity mapping can reveal whether an application outage is due to issues with the network. For example, an employee opens a support ticket when he’s not able to connect to the CRM application. Typically, the ticket will first go to the network team to determine if the problem is network related. Using the application-centric approach with its associated mapping, it is immediately clear whether the issue is network- related. If it is, it can be easily dealt with. If not, it can be sent to the appropriate department, thus saving time and resources

Impact Analysis

Application network connectivity mapping provides a clear picture of the impact on business applications, of any planned changes to the network. This includes firewall changes, or other changes that may cause network downtime. Mapping will enable the implications of the changes to be fully understood and consequently downtime, for example, can be scheduled when it will have minimum impact on customers, partners, or employees.
