What Is Security Vulnerability?

Home | Computers-and-Technology | Mobil-Computing

Security vulnerability is the bug appearing during the concrete function of the hardware, software and Agreement, or in the system security policy, which enable the attackers to unauthorizedly access or damage the system. Let"??s take some examples, such as the logic errors existing in Intel Pentium chip, the programming errors in the earlier version of Sendmail, the weaknesses in the authentication way of NFS Agreement, the problem of Unix system administrator setting anonymous FTP service without correct configuration, etc. All these errors or problems are likely taken advantage by attackers and threaten the system security, so that they can be considered as system security vulnerability.

Relation and time-related features between security vulnerability and specific system environment:

1.Vulnerability may have impact on a large number of software or hardware devices, including the system itself and its built-in software, Network client and server software, network routers, and security firewall, etc. In other words, between different versions of different software and hardware devices or the same device, different systems composed by different devices, as well as different configurations in the same system, various security vulnerability problems exist.

2.The security vulnerability problem is closely connected with time. A system from the day of release, as it is used in depth, will have vulnerabilities exposed gradually. The previous found vulnerabilities can be repaired constantly by the patches released by the system suppliers, or will be corrected in the new version of the system released later. However, a new version of the system that has corrected the vulnerabilities in the old system will also bring in some new security vulnerabilities and errors. Therefore, as time goes by, the old vulnerabilities continue to disappear, and the new will continue to appear. The vulnerabilities will exist for a long term.
