There are some essential regions of network security offerings to don’t forget, as follows:
Firewall configuration evaluate, to check that the guidelines currently followed via the firewall, and the kind of firewall used, are suitable to the given state of affairs.

Network vulnerability evaluation, to check previously-addressed vulnerabilities to ensure that they are nonetheless blanketed with the aid of powerful countermeasures.
Penetration trying out, to probe the defences actively for brand new vulnerabilities.

Protocols and ports supported: If the network supports services and open ports (including “Telnet” on port 23) that are not certainly required through your agency, then they must be disabled for safety motives.
Auditing and tracking centers: Are there logs of network interest and are they in a shape that can without difficulty be scanned by means of a human?
