check Assessing security with a network analyzer

check Preventing denial of service and infrastructure vulnerabilities

To have secure operating systems and applications, you need a secure network. Devices such as routers, firewalls, and even generic network hosts (including servers and workstations) must be assessed as part of the security testing process.

Thousands of possible network vulnerabilities exist, along with equally many tools and even more testing techniques.

Instead, you need to focus on tests that produce a good overall assessment of your network. The tests I describe in...
