The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). Since 2000, secure networks have been built by segmenting traffic at the switch port level from server to server, radically limiting east-west traffic. Microsegmentation will fix this.

As we continue down the path to successfully securing our infrastructure, we come to vulnerability scanning. A vulnerability scan simply scans for security flaws in systems and devices known as vulnerabilities and reports them. For internal vulnerability scanning, you can set up an OpenVAS server running on Linux.
