Large quantities of computer code are written, debugged, published, and sold before all their bugs are detected and resolved. Sometimes, combinations of certain software and hardware reveal new bugs. These failures range from bugs to untested failure conditions. Sometimes these bugs are not errors, but rather purposeful shortcuts left by programmers for benign or malign reasons. Collectively, shortcut access routes into programs that bypass security checks are called trap doors and can cause serious security breaches. Software bugs are so commonplace that entire Web sites are dedicated to documenting them. Among the most often used is Bugtraq, found at www.securityfocus.com, which provides up-to-the-minute information on the latest security vulnerabilities, as well as a very thorough archive of past bugs.
