Common Vulnerability Scoring System (CVSS)

​It is common for a vulnerability to get CVSS (CVSS stands for Common Vulnerability Scoring System) rating. CVSS score will tell how bad such a vulnerability is. CVSS has a numerical value associated with a vulnerability, the score ranges from 0 to 10. 0 means minimal impact and 10 means maximum impact.

CVSS is the way vulnerabilities can be prioritized. A person that is fixing issues needed to focus on higher CVSS scores first, because such vulnerabilities have potential to cause more harm.

It doesn’t mean that vulnerabilities with lower score can be disregarded, they just represent less harm. For example a version of web server maybe known. By itself such information can not be exploited, however knowing a version of a we server can be combined with other vulnerabilities, such as how such a web server can be exploited.

Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...
