Which firewall implementation creates a buffer network that can be used to host email or web servers?
While security policy rules enable you to allow or block traffic on your network, security profiles help you define an allow but scan rule, which scans allowed applications for threats, such as viruses, malware, spyware, and DDOS attacks. When traffic matches the allow rule defined in the security policy, the security profile(s) that are attached to the rule are applied for further content inspection rules such as antivirus checks and data filtering.

Security profiles are not used in the match criteria of a traffic flow. The security profile is applied to scan traffic after the application or category is allowed by the security policy. You can add security profiles that are commonly applied together to Create a Security Profile Group; this set of profiles can be treated as a unit and added to security policies in one step (or included in security policies by default, if you choose to set up a default security profile group).
