One the types of attacks to breach the security of systems is to attempt to guess the access passwords of the system users. Usually, the attacker resorts to dictionaries of common passwords that users tend to use, and try them all until one succeeds. This brute force attack method is usually known as dictionary attack. This class provides a solution to protect against dictionary attacks a site that require the users to authenticate to have access to restricted pages. It keeps track of login attempts to the same account, disabling access to that account for a given period after a few consecutive failed attempts. This way, dictionary attack attempts are discouraged as they may take a very very long to be successful. Manuel Lemos
