Log Watch/Ban Service

This feature allows the PBX to monitor the SIP registration traffic and ban any IP address that makes 3 failed registration attempts. The IP address will be banned for either 3 days or until the service is restarted. Configuration settings allow you to ignore (not monitor) IP addresses that are communicating from the LocalNet, as well as allowing you to manually add addresses you want the system to ignore. If you set up an Admin Email Address under PBX Setup=>General and have Unified Messaging configured, the PBX will send you an email any time an IP address is banned via this feature. Follow this link to see what a Ban Email will look like.

Disable Log Set Security Setting

STEPS:

  1. From the PBX Setup=>General System Setup page, locate the Security Settings panel.
  2. Disable the security setting by selecting “No” from the drop-down list for the Log Watch Ban Service.

It should be noted that the Log Watch is not intended to be the only line of defense for security. It is best practice that if you are being attacked by a intruder, that you permanently ban at the router/firewall level. This keeps the offending traffic off your LAN.
