Abstract


Vulnerability refers to computer systems , hardware , software and protocol specific or safety defects exist on the system security policy , so the attacker may be illegal intrusion system or unauthorized access to , or destruction of the system . According to the Computer Emergency Response Team (CERT) report , 99% of network intrusion security events around the world report are based on known vulnerabilities occur , detect and repair system known security vulnerabilities very important to ensure network security significance , but due to various reasons (such as not familiar ) is often difficult to timely and fully test the security of the system . This paper first gives the definition of vulnerability , analysis of causes , characteristics, properties, and probing methods , and discusses the relationship between vulnerability scan . Subsequent analysis of network vulnerability scanning technology used to key technologies , such as port scanning , remote operating system identification , vulnerability scanning and plug-in technology , and knowledge of network programming . Network vulnerability scanning also works more effectively use were introduced . Based on the above basic technology , the article goes on to describe this paper the design and implementation of network security vulnerability scanning system . The system is oriented network vulnerability scanning system , able to collect the remote host and network vulnerability information after the completion of the scanning of the target host , gives a detailed scan report and specific solutions to network security management personnel to maintain the network has brought a lot of convenience . This paper analyzes the features and components of the system , described by some of the key features of the implementation details of the system implementation techniques , and emphatically describes the validation of improved OVAL vulnerability detection techniques , based on the CVE database design , simulate hacker attacks program of technology as well as bug fixes .
