 +======2.2.3 Ensure Avahi Server is not enabled (Scored)======
 +=====Profile Applicability=====  ​
 +<​code>​
 +Level 1 - Server
 +Level 1 - Workstation ​
 +</​code>​
  
 +=====Description=====
 +Avahi is a free zeroconf implementation,​ including a system for multicast DNS/DNS-SD service discovery. Avahi allows programs to publish and discover services and hosts running on a local network with no specific configuration. For example, a user can plug a computer into a network and Avahi automatically finds printers to print to, files to look at and people to talk to, as well as network services running on the machine.
 +
 +=====Rationale=====
 +Automatic discovery of network services is not normally required for system functionality. It is recommended to disable the service to reduce the potential attach surface.
 +
 +=====Audit===== ​
 +Run the following command to verify ''​avahi-daemon''​ is not enabled:
 +<​Code:​bash>​
 +# systemctl is-enabled avahi-daemon ​
 +disabled
 +</​Code>​
 +Verify result is not "​enabled"​.
 +
 +=====Remediation===== ​
 +Run the following command to disable ''​avahi-daemon'':​
 +<​Code:​bash>​
 +systemctl disable avahi-daemon
 +</​Code>​
