Network Service Scanning Mitigation

Use network intrusion detection/prevention systems to detect and prevent remote service scans. Ensure that unnecessary ports and services are closed and proper network segmentation is followed to protect critical servers and devices.

Identify unnecessary system utilities or potentially malicious software that may be used to acquire information about services running on remote systems, and audit and/or block them by using whitelisting^[1] tools, like AppLocker,^[2],[3] or Software Restriction Policies^[4] where appropriate.^[5]
