Cisco SA-ISA

The Cisco SA-ISA (Security Appliance - Intrusion Sensor Adapter) is a network security device developed by Cisco Systems. It is designed to enhance network security by providing intrusion detection and prevention capabilities. The SA-ISA is typically deployed in conjunction with Cisco's Intrusion Detection System (IDS) or Intrusion Prevention System (IPS) to monitor network traffic, detect potential threats, and take appropriate actions to prevent or mitigate attacks. It acts as an adapter that connects the IDS/IPS sensors to the network infrastructure, allowing them to monitor and analyze network traffic for any suspicious or malicious activity.
