Firewall security level is the degree to which a firewall blocks unauthorized access to a computer system. There are four different firewall security levels:

1. Protected: This is the default security level and it blocks all incoming and outgoing traffic.

2. Permissive: This security level allows some incoming and outgoing traffic, but blocks most other traffic.

3. Enhanced: This security level allows more incoming and outgoing traffic, but still blocks most other traffic.

4. Insulated: This security level allows no incoming or outgoing traffic.
