Cisco Firewall
Cisco ASA firewall security:- ASA Security Levels are used to define how traffic initiated from one interface is allowed to return from another interface. Higher level security interfaces can initiate traffic to a lower level without an access list. Any traffic returning from a higher level initiated communications are allowed to pass thru from lower to higher security levels. The higher the security level setting on an interface, the more trusted it is.When configuring an ASA, no access lists are required for traffic from a high security level interface to go thru a low security level interface. And return traffic for the high level to the low level is allowed to passed based on it meeting expected criteria in the ASA translation tables.The ASA allows traffic to pass from trusted network to untrusted network, but not the reverse. Each interface must have a security
