A custom application allows you to customize
the definition of the internal application—its characteristics, category
and sub-category, risk, port, and timeout—and to exercise granular
policy control and help eliminate unidentified traffic on your network.
Creating a custom application also allows you to correctly identify
the application in the
ACC
and traffic logs,
and is useful in auditing/reporting on the applications on your
network. To create a custom application, specify a signature and
a pattern that uniquely identifies the application and attach it
to a Security policy rule that allows or denies the application.
