The Relation Between Bug and System Attack

System security vulnerabilities in the system to achieve concrete and specific errors in use, but not the existence of the error system are security vulnerabilities. Can only pose a threat to system security vulnerability is an error. Many errors in normal circumstances will not jeopardize system security, only to be deliberately under certain conditions that can affect the use of system security.

System suppliers will release as soon as possible to address the vulnerability patch to correct this error. This is the system security vulnerability was found to be from the general process of correcting.
System to attack the security vulnerabilities are often the discoverers and users, it is necessary to attack a system, if the system can not be found and the use of existing security vulnerabilities is not possible to succeed. For a higher security level, especially in the system. Bug and System Attack
System vulnerabilities to attack and system activities are closely related. Attack and therefore should not be divorced from the activities of the system to talk about the issue of security vulnerabilities. Common understanding of system attack, targeted for the understanding of system vulnerabilities, as well as to find the appropriate remedy is necessary .
