1. Overview
COS-03.05B
At specified intervals, the business justification for using all services, protocols, and ports is reviewed. The review also includes the justifications for compensatory measures for the use of protocols that are considered insecure.
The review of the security requirements depends on the measures implemented to design the networks, e.g. monitoring and reviewing firewall rules or log files for abnormalities as well as visual inspections of physical network components for changes.
