Method and system for virtual dial-up safe access

Abstract

The invention discloses a method and a system for virtual dial-up safe access. The method comprises the following steps that: a user terminal sends an internet accessed authentication request; after the authentication request of a user reaches a broadband access server (BAS) in an access network, the BAS sends the authentication request to an authentication, authorization and accounting (AAA) system, the AAA system selects a corresponding access mode according to the corresponding relation between a domain name inquired and saved by a domain name in the authentication request of the user and the access mode, and if the access mode is a common broadband access mode, the access network normally processes user traffic in a common broadband access mode after the authentication passes; and if the access mode is a safe broadband access mode, the access network draws and converges the user traffic which uses safe access service to a safe access service center after the authentication passes. The method and the system can provide full network safety protection service for broadband users and protect network and data safety of the users.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a virtual dialing security access method and system based on metropolitan area network traffic diversion and on-demand protection. Background technique [0002] UTM (United Threat Management, Unified Threat Management) is a special-purpose device composed of hardware, software and network technology. It mainly provides one or more security functions. It integrates multiple security features into one hardware device to form a A standard unified management platform. A typical UTM product integrates many commonly used security functions such as firewall, anti-virus, IPS, and anti-spam. Users can choose a UTM device with comprehensive functions, or select certain functions according to their own needs. UTM products provide users with a more flexible and manageable choice. Users can build their own security infrastructure on a more unified architecture, and problems such as the...
