Explanation:

This is the default signature. You can create multiple security policies and apply them to individual
virtual sensors. A security policy is made up of a signature definition policy, an event action rules
policy, and an anomaly detection policy. Cisco IPS contains a default signature definition policy
called sig0, a default event action rules policy called rules0, and a default anomaly detection policy
called ad0. You can assign the default policies to a virtual sensor or you can create new policies.
