Description
Technical field
The present invention relates to industry control security technology areas, more particularly to the defence of the industry control Environmental security based on service order model
Method and system.
Background technology
Industrial control system is widely used in China's electric power, water conservancy, sewage disposal, petrochemical industry, metallurgy, automobile, aviation
Many modern industries such as space flight, since the importance of industrial control system has become many targets of attack for not sending out molecule.Such as
Ukraine's power events, hacker obtain operating personnel's account access right, power supply system are remotely closed by legal means,
Cause heavy losses.
The defence difficult point that industrial control computer terminal security faces at present is as follows:
1. equipment is numerous, model is complicated, it is difficult to which unified install anti-malicious code software;
2. traditional anti-virus mode is not appropriate for industrial control equipment, it be easy to cause and manslaughters, influences business stabilization;
3. equipment mostly uses greatly isolation network, system vulnerability quantity is more;
4. hacker in order to attack industrial control system, can use protracted war mode, leaky can may be hacked if even if taking precautions against tight again
Visitor utilizes;
5. internal control is not stringent, huge security risk can be become because operating personnel's misoperation or malice use etc..
In general, hacker can obtain the control ability of industry control host computer with this by being implanted into malicious file to net, then to
Execution machine issues malicious instructions(Such as it closes, heavy-duty service etc.)Industry control network environment is destroyed with this.And it is issued for hacker
Instruction, although malicious instructions, system, which will be considered that, to be normal instructions and is executed, therefore for industry control safety, is needed
A set of method analyzed and judged that can send instructions under, prevents issuing for malicious instructions.
