The SonicWall application signature databases are part of the application control feature, allowing very granular control over policy configuration and actions relating to them. These signature databases are used to protect users from application vulnerabilities as well as worms, Trojans, peer-to-peer transfers, spyware and backdoor exploits. The extensible signature language used in the SonicWall Reassembly-Free Deep Packet Inspection engine also provides proactive defense against newly discovered application and protocol vulnerabilities.
