Analysis: Perimeter exploit exposure

Powered by SC Magazine
 

Vulnerability and patch management is key.

What is it?

Perimeter Exploit Exposure occurs when organisations aren't properly filtering enterprise network services at the network egress points. This allows attackers to remotely exploit services that should not be exposed. Although basic security practice, it is easy to forget what's exposed on an internet perimeter.

How does it work?

An attacker can easily use network mapping and vulnerability scanners to discover exposed services available at the perimeter.

Should I be worried?

Yes. We tend to lose focus when a new attack vector is introduced and forget to consider basic principles. However, it is covering the basics that can lower an attack surface.

How can I prevent it?

Vulnerability and patch management is the cornerstone. Organisations can restrict services available at the perimeter, while scanning for exposures and, when necessary, securing and patching those services. Open ports should also be removed when they are no longer needed.
