There are lots of scanning and cracking tools available that know how to find and exploit known weaknesses on most computer systems. Your best defense against this kind of threat is to understand the basics of system security. This will enable you to implement the necessary defenses against potential crackers. This will also give you the tools you need to monitor your system's security on an ongoing basis. Luckily, a vast number of tools exist to aid you in this pursuit.
