tricky but will better for security for the network. There are three different types of ACLs‚ Dynamic ACL‚ Reflexive ACL‚ and Time Based ACL. Each ACL is unique to the type of network we have. Dynamic are also called lock-and-key ACLs which only allow IP traffic only. Also the lock-and-key authenticates the user and permits limited access through the firewall router for a host for a time. Time Based ACLs are a specific time that traffic is allowed on the network. When the device determines that an ACL
