Introduction to ASA-RESTAPI-7161-LFBFF-K8.SPA Software

The ASA-RESTAPI-7161-LFBFF-K8.SPA is Cisco’s official REST API agent for Adaptive Security Appliance (ASA) firewalls, designed to enable programmatic management of security policies, monitoring, and configuration workflows. This plugin extends ASA’s capabilities by exposing over 200+ API endpoints for HTTP/HTTPS-based interactions, aligning with modern DevOps practices for network automation.

Compatible with Cisco ASAv (Adaptive Security Virtual Appliance) and select physical ASA 5500-X series models, this version (7161-LFBFF-K8) was released in Q3 2023 to support ASA OS versions 9.16(4) and later. It replaces legacy ASDM management with JSON-native operations, reducing CLI dependency by 40% in typical deployment scenarios.
