Abstract


Along with the rapid development of the computer and network technology, information systems have been gradually into professions, and the information system security has become the focus of people. People enjoy the convenience and opportunities brought by information technology. How to ensure the security of information systems is a serious problem to be solved. As network attacks and development of technology continuously updated, a number of previous attacks against the network security defense measures have been powerless, the pre-recognition systems are very important to the security situation, which objectively call for the need to strengthen information system security assessment studies. The aim of safety assessment is that before the attack on the entire network system, we make the system an accurate assessment of security conditions, and then give the results to the system security administrator, who can take corresponding security measures in time.This article proposes an information security assessment method based on AHP, through deep research and analysis on the theories and methods of the existing safety assessment. The method includes establish of the evaluation index system, determination of the index-weight and experts-weight, and determination of the security level of target system. The purpose of the evaluation method is used to conduct comprehensive assessment of the security situation by single-assessment and many-assessment of the network and determine the security level of network system. At last, the system generates a security assessment report, which can reflect more directly the situations of the current system security configuration.This article also designs and implements a safety assessment prototype system which is based on the evaluation method. The system can extract evaluation index, classify the experts, determine experts-weight and evaluation index-weights. It can also make comprehensive assessment for the target system, get the goal system security level and will output the assessment results. Through the single-assessment and many-assessment test of the system, it can verify the feasibility of the evaluation method.
