IntroductionIn order to utilize the most effective tools for breaking into their own site, IT administrators must fully review and evaluate the siteÃÂs issues of vulnerability. This requires gathering as much information as possible about the site as if you where an intruder. For this to be successful, an IT administrator must now consider his or her site to be the ÃÂtarget hostÃÂ. Here the administrators have at their disposal such services as finger, showmount and rpcinfo to initially aid in this effort. In addition, using some of the many other available security tools such as the remote probing SATAN (Security Analysis Tool for Auditing Networks) will give the administrator factual details on the siteÃÂs various bugs and inherent weaknesses.
The article "Improving the Security of Your Site by Breaking Into it" allows IT administrators to look at their own network security through the eyes of an intruder. By utilizing the same tools as potential intruders, not only can administrators identify potential security holes in their existing network, but they can also raise the level of awareness and preparedness when it comes to intrusions.
