Application Signatures
Applications are networked services that run in the internal network or on the internet. Application definitions are a way to attach a business relevancy to all traffic that goes through your network. A separate application definition allows you to configure multiple rules using the same application.
Application definitions also let you group applications, so that you can configure and reuse a single rule for multiple applications with similar characteristics and requirements. Using an application group means that you don’t have to repeat the application definition for each rule, which can reduce the number of rules significantly.
You can regulate access to applications using policy rules; for details, see the “Policy controls” section in the SteelConnect Manager User Guide.
Some applications can be detected on the first packet; these applications are identified in the application catalog with “1st packet.” Other applications can only be detected after some data have been exchanged, usually on the fourth or fifth packet.
