Sophos Clientless SSO Authentication

Sophos Clientless SSO is in the form of Sophos Transparent Authentication Suite (STAS). The STA Suite consists of:

Sophos Xg Active Directory Authentication

  • The STA Agent: monitors user authentication requests and sends information to the STA Collector for authentication.
  • The STA Collector: collects the user authentication requests from the STA agent, processes the request, and then sends them to the XG Firewall for authentication.

Configuration

  • ADS Configuration:

  • Go to Start > Administrative Tools > Local Security Policy to view Security Settings. Browse to Security Settings > Local Policies > Audit Policy and double click on Audit account logon events to view the Audit account logon events Properties window.
  • Select both the Success and Failure options and click OK to close the window.
  • While still in the Local Security Policy, browse to Security Settings > Local Policies > User RightsAssignment and double click on Log on as a service to view the Log on as a service Properties.

    • AD Server: Inbound UDP 6677, Outbound UDP 6060, Outbound TCP 135 & 445 (if using Workstation Polling Method WMI or Registry Read Access), Outbound ICMP (if using Logoff Detection Ping), Inbound/Outbound UDP 50001 (collector test), Inbound/Outbound TCP 27015 (config sync).

  • STAS Configuration

    • Log in to your AD Server using an Administrator account and follow the steps below to install and configure STAS
    • Download STAS from the graphical user interface (GUI) of the XG Firewall, go to Authentication > … (click on the … symbol at the far right of the authentication menu) > Client Downloads and install it on the AD Server.
    • You can also download STAS from the Download Clients page in the User Portal while logged in as an Administrator.
