Deploying Sophos Enterprise Anti-Virus for Mac OS X 9.x

September 2, 2014 27 comments

For the past few major releases, Sophos used a standard installer package to install both their free and paid antivirus solution. With the release of Sophos Anti-Virus 9.x though, Sophos changed how their antivirus solution for Macs was installed. Sophos has now switched to using an application to install their antivirus. However, for their customers using Sophos Enterprise Console, Sophos still provides an installer metapackage. This is good news for Mac admins, but the configuration and login credentials that used to be stored in /Library/Preferences/com.sophos.sau.plist in Sophos 8.x has been overhauled in Sophos 9.x. /Library/Preferences/com.sophos.sau.plist in Sophos 9.x now no longer contains login information, only server locations.

The login credentials no longer being available in /Library/Preferences/com.sophos.sau.plist meant that the Sophos Anti-Virus client was not able to connect back to the Sophos enterprise console and receive either management or updates. Since those login credentials were working in my shop for machines in Active Directory OUs that the Sophos enterprise console was managing, that meant that those credentials were available somewhere on the system. After working on the problem in his own shop, Tim Kimpton figured out that both of the following files were needed:

/Library/Preferences/com.sophos.sau.plist

/Library/Sophos Anti-Virus/Sophos.keychain

Once I had this information and understood what was going on, I was able to build and deploy a Sophos Enterprise Anti-Virus for Mac OS X 9.x installer that was able to install a pre-configured set of auto-update settings. For more details, see below the jump.
