Abstract


With the rapid development of Internet, information technology has become more and more important in our daily life. The information technology turns into an important productivity to symbolize the comprehensive national power and social progress nowadays. In recent years, information construction in China has made a great progress, and so does the information systems. Along with the rapid development of information construction, the big challenge of the safety of information system goes along, which can not be neglected. The current threats to the information network are as follows: network attacks, virus attacks and man-made destruction, and so on. How protect the data security and make sure a safe operation of the network equipment, so as to prevent the vocational college information network system from unauthorized intrusion.This paper studies the security risks related to information systems theory, risk analysis of existing advantages and disadvantages of a variety of analysis and comparison of information systems for vocational colleges, a new ternary proposed integrated approach will improve the OCTAVE, and AHP, FTA as comprehensive integration of three basic elements to complete the evaluation from qualitative to quantitative calculations, a comprehensive analysis of information security risk higher vocational colleges. In the new three integrated method based on the combination of higher vocational colleges characteristics of information systems, information systems risk assets from the risk source derived, according to the source of the risk out of the system vulnerabilities, and vulnerabilities for the risk probability and risk of loss assessment, the last use of new three integrated approach to achieve information system security risk assessment.According to this method of risk assessment risk assessment information system built software platform, the application of this platform to establish an information database of risky assets and the corresponding vulnerability for risk assets, libraries, according to the risk of vulnerability to establish the corresponding basic probability and risk loss of data, the use of The new algorithm based on data for system risk assessment of risk assets, obtained results of the evaluation of the risk assets. As the environmental conditions change, vulnerability data can be adjusted for risk, the risk of re-evaluation of the system. Vocational ultimately risk analysis of information system security risk assessment of information provided an excellent solution for real-time monitoring assessment for the College to provide a good means of information risk.
