The Security profile that should be applied in order to protect against illegal code execution is the Vulnerability Protection profile on allowed traffic. The Vulnerability Protection profile defines the actions that the firewall takes to protect against exploits and vulnerabilities in applications and protocols. The firewall can block or alert on traffic that matches a specific threat signature or a group of threats. The Vulnerability Protection profile can prevent illegal code execution by detecting and blocking attempts to exploit buffer overflows, format string vulnerabilities, or other code injection techniques1. To apply the Vulnerability Protection profile on allowed traffic, you need to:
* Create or modify a Vulnerability Protection profile on the firewall or Panorama and configure the rules and exceptions for the threats that you want to protect against2.
* Attach the Vulnerability Protection profile to a Security policy rule that allows traffic that you want to scan for vulnerabilities3.
* Commit the changes to the firewall or Panorama and the managed firewalls.

A user can assign a tag group to a policy rule in the policy creation window by selecting the General tab. A tag group is a collection of tags that can be used to identify and filter policy rules based on different criteria, such as function, location, or priority. A user can create a tag group on Panorama and assign it to a policy rule to apply the same set of tags to multiple firewalls or device groups1. To assign a tag group to a policy rule, the user needs to:
Select the General tab in the policy creation window.
Click the Tag Group drop-down menu and select the tag group that the user wants to assign to the policy rule.
Click OK to save the changes. The policy rule will inherit the tags from the tag group and display them in the Tag column.
