A security profile group is a set of security profiles
that can be treated as a unit and then easily added to security
policies. Profiles that are often assigned together can be added
to profile groups to simplify the creation of security policies.
You can also setup a default security profile group—new security
policies will use the settings defined in the default profile group
to check and control traffic that matches the security policy. Name
a security profile group default to allow the profiles in that group
to be added to new security policies by default. This allows you
to consistently include your organization’s preferred profile settings
in new policies automatically, without having to manually add security
profiles each time you create new rules.
