About overrides in policies
Policies in Deep Security are intended to be created in a hierarchical structure. As an administrator you begin with one or more base policies from create multiple levels of child policies which get progressively more granular in their detail. You can assign broadly applicable rules and other configuration settings at the top level policies and then get more targeted and specific as you go down through levels of child policies, eventually arriving at rule and configuration assignments at the individual computer level.
As well as assigning more granular settings as you move down through the policy tree, you can also override settings from higher up the policy tree. This Overrides page shows you whether and how many settings have been overridden at this policy or specific computer level. To undo the overrides at this level, click the Remove button.
