Attacking Linux Servers

In a networked world where even refrigerators are given IP addresses, network security becomes ever more important.

Focussing on the technical aspects of network security, convenient and easy-to-use scanners are available that check for vulnerabilities and misconfiguration. (Other important matters such as policies and user awareness, will not be addressed by this short talk.)

These integrated tools are quite popular for penetration testing, but they lack many of the options that a truly-dedicated attacker would have at his hands.

We will therefore present a top ten list of basic utilities which, supported by the powerful system commands in a Linux distribution, form a toolbox that lets you find out the security level of your network before the bad guys.

We will explain the objective and functionality of each tool and demonstrate its usage with live examples. Armed with knowledge of potential threats, you can prepare countermeasures.
