Design of Vulnerability Scanner Based on a UNIX Host

Faced with more network security problems, the paper analyzes the inevitability of the existence of security vulnerabilities in UNIX host systems and presents the design goal of security vulnerability scanner based on a UNIX host. A vulnerability scanner is designed based on a UNIX host system and its system constitution and implement principle analyzed. This scanner can scan the destination server from inside and outside. Experiments show that users can find security vulnerabilities of a local or remote server using this scanner.
