Configuring Protocols and Maps for Inspection
Configuring SIP Maps
Use the Add and Edit SIP Map dialog boxes to configure values used for SIP application inspection. A
SIP inspection map lets you change the default configuration values used for SIP application inspection.
SIP is a widely used protocol for Internet conferencing, telephony, presence, events notification, and
instant messaging. Partially because of its text-based nature and partially because of its flexibility, SIP
networks are subject to a large number of security threats.
SIP application inspection provides address translation in message header and body, dynamic opening
of ports and basic sanity checks. It also supports application security and protocol conformance, which
enforce the sanity of the SIP messages, as well as detect SIP-based attacks.
Navigation Path
Select Manage > Policy Objects, then select Maps > Policy Maps > Inspect > SIP (ASA/PIX/FWSM)
from the Object Type selector. Right-click inside the work area, then select New Object or right-click a
row and select Edit Object.
