What are the main stages of a policy installation?

The main stages of a policy installation are Verification, Compilation, Transfer, and Commit. Verification is the stage where the policy is checked for syntax errors and conflicts. Compilation is the stage where the policy is translated into a binary format that can be executed by the Security Gateway. Transfer is the stage where the policy is sent from the Security Management Server to the Security Gateway. Commit is the stage where the policy is activated on the Security Gateway3.
