Step 3

Enter a unique Name and, optionally, a Description.

Step 4

Choose the Inspection Mode.

The selected action determines whether intrusion rules block and alert (Prevention mode) or only alert (Detection mode).

Note	Before selecting the prevention mode, you might want block rules to alert only so you can identify rules that cause a lot of false positives.

You can use either a system-provided policy or an existing policy as your base policy.

Step 6

Click Save.

The new policy has the same settings as its base policy.
