Intrusion Prevention protects you from attacks when you are online. It scans network traffic for attack signatures, such as social threats and outbound attacks, that identify attempts to exploit vulnerabilities in your operating system or in a program that you use. To keep you secure, Intrusion Prevention discards packets from computers that try to send data with known attack signatures. It blocks connections to those computers.
By default, Intrusion Prevention is turned on. It must be on in order to customize the settings below.
When Intrusion Prevention is turned off, your computer is not adequately protected from Internet threats and security risks.

In some cases, benign network activity may be identified as suspicious, because it has a similar attack signature.
