Research of Security Vulnerability in the Computer Network

In order to solve the problem of security vulnerability in the computer network radically, it was studied for the cause of vulnerability. Solving scheme was put forward aim at one kind of vulnerability, that is, by the special scan and encryption techniques, it makes attacker can't bypass its access control. In this way, it can avoid the vulnerability caused by the error of access verification. Finally, it pointed out that the method solving vulnerability problem according to the cause of vulnerability will be the development trend to study the vulnerability.
