Firewall plays a key role in providing the best protection to organizational networks. They are always monitored and managed by administrators. Their duty is to observe the traffic on the network and avoid data breaches by allowing just authorized users to access the data. They also avoid misconfiguration of the devices which is the primary cause of data breaches.
Organizations that are maintaining confidential data of users carry out certain procedures to overcome the chances of a data breach. From firewall migration to management and maintenance, every activity of the administrator is to overcome the challenges to protect a network. Following are some of the recommended practices everyone must know.
Keep Security Policy Manager In The Loop From Changes:
Organizational security policies are arranged by security managers. They stay in charge to ensure that these policies are followed thoroughly. Beside that fact that they are not operational employees, the administrators must keep them in the loop when deploying rules. Both of them must work together so that none of a corporate policy rules can be violated.
Clean Up Unused Rules:
Among thousands of organizational rules, there must be some out-of-date rules that need to be clean up. Connections are often left unclosed even for a long time that can be noticed by hackers. One must close similar connections that no more serve any business purpose. Such a clean-up improves firewall performance and organizational security.
Conflicting Rules Elimination:
When implementing new rules, the administrator must have an in-depth idea of the existing ones. They must do not implement rules that can conflict with those that are existing. The new rules stay dysfunctional if they are implemented on existing ones. The administrator must have a policy for cleaning up the existing rules when implementing new rules.
Follow A Consistent Work flow Changes Implementation:
Every rule must be properly documentations so that they can help in demonstrating that who owns it. The organizational security managers need to define a business process needs so that a particular workflow can be followed when a rule is required. A better firewall management would be the one where such a workflow covers everything ranging from an access request from the owner to analyzing it and making the changes by the administrator.
Have Developers And Firewall Administrators On The Same Page:
Both the application developers and firewall administrators must have mutual understanding when requesting changes to an already implemented firewall. Using a technical translator is recommended in this regard to avoid misconfiguration and waste of time. The use of higher level language by developers is recommended that can be translated into details of technical implementation by technical translator.
