Problems solved by technology

[0004] The packet filtering firewall adopts passive isolation control technology to check the data packets at the network layer. The advantages are simple and practical, and the speed is fast. The disadvantage is that it cannot meet the high security requirements of the working network.
The proxy firewall uses active detection and scanning technology to monitor data packets at the application layer. The advantage is that it is more effective in preventing known viruses and attack intrusions, and the security is high. The disadvantage is that the management is complicated, the speed is slow, and it cannot defend against unknown features. Viruses and intrusion attacks

Embodiment Construction

[0024] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0025] Such as figure 1 As shown, the working network behavior firewall of the present invention consists of a behavior rule base 10 , a behavior manager 20 and a behavior filter 00 . in:

[0026] The behavior rule library 10 consists of task filtering whitelist 11 and its corresponding process filtering whitelist 12 . Task filtering white list 11 is used to classify and define the work tasks of file processing, and the attributes of work tasks are composed of triplets (staff 13, work target 14 and work authority 15. Process filtering white list 12 is used to define corresponding file processing The workflow, the attribute of the workflow is composed of four tuples (communication port 16, transmission protocol 17, storage data 18 and file format 19).

[0027] The behavior manager 20 is composed of a behavior auditing module 21 , a behavior reporti...

Abstract

The invention discloses a behavior filtering method of a job network behavior fire wall, which comprises the following steps of: receiving a login request of a login user, wherein the login request comprises a required job task; carrying out task filtration on the job task according to a task filtering white list; judging whether the job task subjected to the task filtration is a legal job task or not; carrying out process filtration on the legal job task; judging whether the legal job task subjected to the process filtration is a legal process or not; and providing network services for the job task with legal process so as to avoid all nonstandard network jobs and file processing behaviors and meet the requirements for high safety and high reliability of the job network.

Description

technical field [0001] The invention belongs to the firewall (Fire Wall) technology in the field of information network security, in particular to a behavior filtering method of a working network behavior firewall. Background technique [0002] The network has become the infrastructure for the operation and work of government agencies, enterprises and institutions, and network-based work is becoming the norm. Corresponding to the network of government agencies and units with first-level security protection capabilities (national standard GB17859-1999), only work-related online behaviors are allowed. We call this a work network. The characteristics of the work network are centered on the data flow management of the file as the carrier, and the corresponding workflow is established around the file processing and management to standardize the user's online work behavior, eliminate illegal network work behavior, and ensure the network security and information security of the wor...
