Signature-based IDPS uses a database that contains known attack patterns or signatures. Each signature is associated with a particular type of attack and the IDPS will look for those patterns in order to identify malicious activity. For example, if the signature in the database is associated with a buffer overflow attack, the IDPS will look for that particular pattern of attack in order to detect the attack.

A Denial of Service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. DoS attacks typically flood a network with excessive requests, overwhelming the network and preventing legitimate users from accessing IT resources or services. This type of attack does not compromise user accounts, hijack privileges, or duplicate user credentials, but it does effectively deny service to legitimate users.
