Allow access only to the necessary ports

Allow access only to the necessary ports

Summary

Network segments and servers with applications or content must allow access only to the necessary ports.

Description

Unnecessary open ports increase the likelihood of exposure to exploits and attacks targeting specific services or applications. Closing unused ports mitigates the risk of exploitation and limits the potential impact of security vulnerabilities.
Additionally, proper segmentation of network resources and restriction of ports contribute are important parts of a secure network architecture.
