Introduction to the Cisco ASA 5500 Series
Adaptive Security Appliance
The adaptive security appliance combines advanced stateful firewall and VPN concentrator functionality
in one device, and for some models, an integrated intrusion prevention module called the AIP SSM/SSC
or an integrated content security and control module called the CSC SSM. The adaptive security
appliance includes many advanced features, such as multiple security contexts (similar to virtualized
firewalls), transparent (Layer 2) firewall or routed (Layer 3) firewall operation, advanced inspection
engines, IPSec VPN, SSL VPN, and clientless SSL VPN support, and many more features.
Although ASDM 6.3 supports many ASA versions, the ASDM 6.3 documentation and online help only
Note
include features for ASA 8.3. For older ASA versions, you might find that using the ASDM 6.3
documentation is inaccurate for your older feature set. Instead, refer to the ASDM guide in which
support for your platform version was added (see
Appliance Hardware and Software Compatibility
ASA version). Although the specific information about the ASDM GUI might be inaccurate in that
guide, the platform feature set is documented correctly.
