The alignment of a particular prevention policy to one or more host groups can be completed in each policy in the "Assigned Host Groups" tab. This tab allows the administrator to select which host groups will use the policy, as well as view the number of hosts and sensors assigned to each group. The other options are either incorrect or not available.

The scenario that best describes when you would add IP addresses to the containment policy is that your organization has resources that need to be accessible when hosts are network contained. As explained in the previous question, adding IP addresses to the containment policy allows you to create an allowlist of trusted IP addresses that can communicate with your contained hosts. This can be useful when you need to isolate a host from the network due to a potential compromise or investigation, but still want to allow it to access certain resources or services that are essential for your organization's operations or security.

The best approach to updating the Containment Policy to allow a new patch server that should be reachable while hosts in your environment are network contained is to add an allowlist entry for the individual server's IP address. An allowlist entry allows you to define a list of trusted IP addresses that can communicate with your contained hosts. This way, you can isolate a host from the network while still allowing it to access essential resources or services, such as a patch server. If the server's IP address is static and does not change, adding an individual IP address is more precise and secure than adding a host group or a network range.
