About Firewall Auditing

A firewall is an integrated collection of security measures designed to prevent unauthorized electronic access to a networked computer system. It is also a device or set of devices configured to permit, deny, encrypt, decrypt, or proxy all computer traffic between different security domains based upon a set of rules and other criteria.
Without proper configuration, a firewall can often become worthless. Standard security practices dictate a “default-deny” firewall ruleset, in which the only network connections which are allowed are the ones that have been explicitly allowed. Unfortunately, such a configuration requires detailed understanding of the network applications and endpoints required for the organization’s day-to-day operation. Many businesses lack such understanding, and therefore implement a “default-allow” ruleset, in which all traffic is allowed unless it has been specifically blocked. This configuration makes inadvertent network connections and system compromise much more likely.

Many organizations implement firewalls without understanding the underlying technology or realizing the need for architecting a comprehensive policy for such firewalls. This leads to a false sense of complacency and security. Firewalls are used to prevent unauthorized persons from accessing private networks connected to the Internet. Data entering or leaving the Intranet passes through the firewall, which examines the data and blocks data that does not meet the specified security criteria.
Through the Firewall Auditing Service, Infysec carries out a detailed review of the firewall configuration, either on-site or remotely, for secure practices, optimal organization of rules, etc. Our consultants analyses and rectify configurations, simplify the organization’s rule-sets and related objects, and fine-tune the performance of the firewall and set appropriate operating system parameters. They also review random samples of log-files for suspicious activity. As a result of a firewall audit, an organization obtains a firewall that is optimized for security and performance. A summary of findings that includes remedial needs and suggestions for improvement of security and management is also provided.
A detailed firewall audit provides a certain level of comfort that all possible security and continuity risks are being adequately addressed and also ensures that an adequate level of network integrity and security is achieved and maintained. Areas that are covered under a firewall audit are:

Firewall Management and Administration
Firewall Policies and Procedures
Firewall Configuration
Firewall Logical Access
Operating System Logs
Firewall Test
Physical Security
Continuity of Operations

Firewall audit service can simplify management of your back-end Web applications.You can use it to virtualize the endpoint address, handle rate limit requests, and enforce access control. You can configure these items using the firewall audit service without writing any custom code.
