Implicit policy of ACL

Hi - What is the implicit policy for NGAF 8.0.47 either "permit any any" or "deny any any" on firewall ?

HiHi,

As far as I know, the firewall follows a top-down approach when prioritizing policies. To block or deny specific elements, position them at the top & consider that the default policy already allows all traffic.

Hi, the purpose to set a policy deny any is to catch all traffic that you want to block (unwanted traffic) and log it. This policy must stand down all the other policies that permit the traffic you wnat to allow. The policy allow all i use only for test purpose, as i recommed to create specific firewall rules to match properly the allowed traffic.

Best Practice is implicit deny, the advantages is you can added an object and services/apps then allow them using specific permission but you must remember the firewall read the policy from top to bottom.

This means that by default, if there are no explicit firewall rules defined to permit traffic, all traffic is denied. This ensures a default stance of security where traffic must be explicitly allowed by firewall rules to pass through the firewall.

The purpose of setting a policy to Deny Any is to block all unwanted traffic that passes the Firewall, it's a best practice of the Firewall. The NGAF's default policy are set to Deny Any Any, users must configure a policy that allows necessary traffic through the NGAF to ensure all approved traffic is permitted.

The matching mechanism of the NGAF's Application Control Policy is from Top to Bottom, normally allowing policies to be on top and the Default Policy at on bottom.

The implicit policy for NGAF 8.0.47 is "deny any any." This means that by default, all traffic is blocked unless explicitly allowed.

By default no rule is applied , all traffice are in deny mode . we create the rules as per requirement.

The implicit policy for NGAF 8.0.47 firewall is typically "deny any any." This means that by default, all traffic is blocked unless explicitly permitted by firewall rules. This approach enhances security by preventing unauthorized access, but requires administrators to configure specific allowances for desired traffic to flow through the firewall.

Implicit policy of all version on NGAF is "Deny ALL-> Source ANY -> Destination ANY"
