This checklist ensures the proper configuration of firewalls to protect the network from unauthorized access and potential threats. It provides a step-by-step process to verify settings and rules associated with the firewall.
Identify the specific network segments that require firewall protection and the types of traffic that need to be allowed or blocked.
Create a list of rules that specify which types of traffic are allowed and which are denied, based on the assessment performed.
Access the firewall's management console and apply the defined rules. Ensure that all settings are configured as per the security policy.
Conduct tests to verify that the firewall is correctly blocking/allowing traffic as per the defined rules. Use tools to simulate various traffic scenarios.
Maintain documentation of the firewall rules, configurations, and any changes made. This documentation should be stored in a secure, accessible location.
Establish a timeline for periodic review of the firewall settings and rules to ensure that they remain effective and relevant to current security needs.
