22.2 Keeping Current

Security tools and vulnerabilities change every day. Each day new exploits are published and new tools and scripts posted or updated. Since the field changes so quickly, you need to develop ways to keep current. Here we describe some of the methods we use. We monitor key Web sites that provide security and vulnerability information, subscribe to security-related mailing lists, and read trade magazines and white papers. These sources provide information on new developments and exploits. By constantly monitoring these sources of information, we can incorporate new findings into our testing procedures. Organizations can use the information to safeguard their systems against the latest vulnerabilities, obtain new testing tools, and develop new procedures for security testing. Below we list some of the sites and mailing lists we have found useful.

22.2.1 Web Sites

One of the keys to keeping current is to find the sites and lists where the best players in the industry discuss and publish the latest tools and techniques. There are many security sites on the Internet. Listed below are some of the sites we have found helpful.

22.2.2 Mailing Lists

In addition to Web sites, mailing lists can provide useful information. Many of these lists provide insight into the latest trends and developments in the security arena. There are many excellent mailing lists available today. Below we highlight some of the lists we have found helpful.
