Complete Definition

ASA in Cisco ASA stands for Adaptive Security Appliance.

In brief, Cisco ASA is a  security device that combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities.  It provides proactive threat defense that stops attacks before they spread through the network.

An ASA is valuable and flexible in that it can be used as a security solution for both small and large networks.

The Cisco ASA 5500 series is Cisco’s follow up of the Cisco PIX 500 series firewall.  However, the ASA is not just a pure hardware firewall. In brief, the Cisco ASA is a  security device that combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities.  It provides proactive threat defense that stops attacks before they spread through the network. Indeed, it’s the whole package, so to speak.

Beyond being a firewall, the Cisco ASA can do the following and more:

  • antivirus
  • antispam
  • IDS/IPS engine
  • VPN device
  • SSL device
  • content inspection

If it is new deployment, you need to create SSH key by using command “crypto key generate rsa mod 2048”.
