ABSTRACT
Many of the tools described in this entry have dual personalities; they can be used for good or evil. When used by malicious individuals, the tools allow a motivated attacker to gain access to a network, mask the fact that a compromise occurred, or even bring down service, thereby impacting large masses of users. When used by security practitioners with proper authorization, some tools can be used to measure the security stance of their own organizations, by conducting ethical hacking tests to find vulnerabilities before attackers do.
