Abstract
Methods and apparatus are provided for detecting unwanted traffic in one or more packet networks utilizing string analysis. Unwanted traffic received by a target victim, such as a malicious attack, is detected by maintaining a rule base identifying one or more string expressions; analyzing one or more error entries in a log file, the log file comprising one or more requests received by the target victim; determining if the one or more requests include a string that matches one or more of the string expressions in the rule base; and sending a denunciation message to a central filter if the one or more requests include a string that matches one or more of the string expressions in the rule base. The string expressions may comprise, for example, a string or a regular expression and can represent one or more resources that an attacker may attempt to access.
