Simple intrusion detection

Simple intrusion detection

As we all know, the majority of intrusions occur from inside a company's infrastructure. But all too likely is the fact that little is done to detect these intrusions. The reasons vary from lack of funding to introduce intrusion-detection tools, to lack of personnel to install, manage and monitor these tools. For a company to start gaining an understanding of the issue of internal intrusions, I recommend that they purchase and install a personal firewall product on a system or systems to actually see what is happening. These tools require little up-front configuration and are very inexpensive. So for a little time and cost, companies can start the process of understanding the level of intrusion issues they probably have internally.
