Apart from File AV, how did OneCare for Server work together with other technologies on Windows SBS 2008 to provide defense in depth?
While OneCare for Server and other alternative file AV solutions add file level virus and malware protection, the server is also secured by other layers of protection. This is necessary, for example, in the event a server administrator uses an internet browser from the server itself. This presents a potential risk for infection. Windows SBS 2008 ships with a depth of layers for file and network security. Forefront Security for Exchange (when installed as a 120-day trial with the option to subscribe) will help prevent entrance of viruses into the company via email. Windows Firewall provides protection upon server deployment that is designed to keep network aware viruses from entering the LAN from the server or connecting unauthorized to the server. Another level of protection that comes with Windows SBS 2008 is Windows Server Update Services (WSUS) which provides automatic updates to both the server and client computers joined to the network. Windows Small Business Server during setup automates the configuration of many of these services meaning that tasks sometimes overlooked are in fact automated by SBS.
There are also the other ways to protect your server and client machines. It is possible that client machines can infect the server. Having a separate Domain Admin account that is not used on a daily basis, separates access to the server system from the clients through domain policies. Properly defined and in place ACLs (Access Control List) adds security that helps prevent users from passing data between each other’s private files and the server operating system. This will help keep the server virus free even if clients do get infected. Windows Defender on all newer clients is designed to remove malware, from running on the client, helping prevent the spread of anything to the server. And, Windows SBS 2008 has a built in back-up solution engineered to help protect the server by doing a recovery from a backup copy of the server. The Administrator can, via a (USB 2.0) restore process, roll the server back in time to a point prior to the virus entry into the system, and then take measures to prevent the access of the virus to the clean system.
