Configuring the User Security of Huawei MA5631
Background Information
The user security mechanism includes:
1 PITP: The purpose of the PITP feature is to provide the user physical location information for the upper-layer authentication server. After the BRAS obtains the user physical location information, the BRAS binds the information to the user account for authentication, thus protecting the user account against theft and roaming.
2 DHCP option82: The user physical location information is added to the option82 field in the DHCP request sent by the user. The information is used by the upper-layer
authentication server for authenticating the user, thus protecting the user account against theft and roaming.
3 IP address binding: The IP address of the user is bound to the corresponding service port for authenticating the user, thus ensuring the security of the authentication.
4 MAC address binding: The MAC address is bound to the service port, thus preventing the access of illegal users.
5 Anti-MAC spoofing: It is a countermeasure taken by the system to prevent a user from attacking the system with a forged MAC address.
6 Anti-IP spoofing: It is a countermeasure taken by the system to prevent a user from attacking the system with a forged IP address.
