Description

technical field [0001] The invention belongs to the field of network communication, in particular to a network security service expansion system. Background technique [0002] With the rapid development and wide application of computer network technology, network security has become a crucial issue affecting the development and application of computer network technology. Therefore, various network security devices have emerged and have been widely used. Simple security devices can only implement basic packet filtering and state filtering functions, while complex security devices integrate virtual private network (Virtual Private Network, VPN), network address translation (Network Address Translation) and other functions. To meet the needs of the Internet, units such as content filtering, anti-virus, and intrusion detection system (Invasion Detection System, IDS) can also be embedded in the device. [0003] As shown in Figure 1, in the field of network information security ...
