Environment


  • Prisma Cloud


Cause


  • "iptables" package, that needs to be installed for CNNS, WAAS and Host Runtime DNS protection to work, is missing on the Defender Host


Resolution


  • Confirm whether the "iptables" package is present on the Defender Host
  • If absent, install "iptables-service" on the Concerned Host in order to use CNNS, WAAS and Host Runtime DNS protection
Note : CNNS is going to sunset. Deprecation Notice is released with Maxwell Update 2(30.02 Update 2). If you do not wish to install the iptables, then you can consider keeping the CNNS feature disabled under Compute --> Radar --> Settings
