Microsoft Windows SharePoint Services Technical security measures provide firewall protection,
intrusion detection, and web-publishing rules. The Microsoft operation center team tests and
deploys software updates in order to maintain the highest level of security and software reliability.
Software hot-fixes and service packs are tested and deployed based on their priority and level of

threats. A comprehensive software validation activity ensures software stability through regression
testing prior to deployment.
