Internal Penetration Testing network security firewall computer security Ne

An internal penetration test is usually done after completing an external penetration test.

 This will imitate an insider threat and also identify how an attacker with internal access may compromise or damage the network, systems or data.

  Most organizations focus on external security threats. Yet internal threats coming from malicious insiders, employees, insecure third-party vendors and even clients or customers are equally (if not more) serious than external threats.  

As such, it is highly recommended to conduct an internal pentest at least once a year or following any major changes to the infrastructure to ensure that the enterprise stays on top of the latest hacking methods for penetration.
