What do you understand by Firewall auditing?

Having a firewall audit has become a necessity in the modern world to maintain the firewall security measures and the standards set in the office networks. Considering the huge amount of security measures taken, it can be quite difficult to process a proper audit on the firewall manually.

This step aims at ensuring the fact that the changes that were requested are approved in a proper way with documentation and implementation. This action can be performed in various ways but the same is dependent on how you do it – manual or with help of tools. To audit, the process change one needs to pull data of a minimum of 10 process changes that took place in the previous audit. Of course, there are some questions that assist in preparing your audit data. Check if the documented requester was authorized to place the request for firewall changes. Check for the date of expiry applicable for the change. Ensure a risk analysis is done before the audit change is processed. In case this is performed manually then it is very important to match the policy and each of the firewall changes.

Rule base of the firewall is a technical term used for the policy of firewall. Audit of the policies is the second phase. This audit is highly dependent on technology and hence the process of audit varies to a great extent among different auditors. Doing it manually is traditionally an impossible matter.
