The use of access control lists is specified by the range of numbers, 1000~1999 is an interface-based access control list, 2000~2999-scoped access control lists are basic access control lists, and 3000~3999-scoped access control lists are advanced access control lists. There are two matching sequences: Configuration order, auto sort: ACL number Acl-number [match-order {config | auto}] Several commands that the H3C ACL applies to an interface: I. Packet-filter inbound Ip-group acl-number (versi

That kind man can send me a copy of the Auth and ACLs on the Zend Framework in the practice project. Now we are studying ZF. There are two open-source blogs on the web that look at the code. Not too hard. There is no example where the key is. As I said above. Authentication and access control. I've studied thinkphp. In real-world projects, user groups and access control nodes can be dynamically added! A few things are confusing! 1 ZF put the resources

One method that attackers often use to obtain network information is to impersonate a trusted member of a network. The attacker cheats the source IP address in the packet and sends it to the internal network. An attacker would only need to change

Network designers use firewalls to protect networks from unauthorized use. Consider a lock on a door to a class inside a building. The lock allows only authorized users with a key or access card to pass through the door. Similarly, a firewall filters unauthorized or potentially dangerous packets from entering the network. On a Cisco router, you can configure a simple firewall that provides basic traffic filtering capabilities using ACLs. Administrator
