A preliminary study on time-dependency of cyber security vulnerability assessment

Abstract (in Japanese) (See Japanese page) 
(in English) Information system administrators must pay attention to system vulnerability information and take appropriate measures against security attacks on the systems they manage. However,
as the number of security vulnerability reports increases, the time required to implement vulnerability remediation also increases,
therefore vulnerability risks must be assessed and prioritized. Especially in the early stages of vulnerability discovery, such as zero-day attacks, the risk assessment must consider changes over time，since it takes time for the attack and countermeasures to spread.

The Common Vulnerability Scoring System (CVSS) is used widely for vulnerability risk assessment, but it cannot be said that it can sufficiently cope with temporal changes of risk of attaks.
In this paper, we report a preliminary study on the time dependency model for vulnerability risk assessment.
