Publication of Security Bulletins and Warnings
The main task in providing this service is to announce in a timely manner and distribute appropriately the information concerning the cyber security at the national and international level.
SK-CERT unit for this purpose performs filtration and evaluation of information being gathered from more information sources.
In evaluation of vulnerabilities CVSS v 3.0 metrics is used. The CVSS calculator v 3.0 can be found on FIRST webpage here.
| Score | Severity |
| 0.1 – 3.9 | Low |
| 4.0 – 6.9 | Medium |
| 7.0 – 8.9 | High |
| 9.0 – 10.0 | Critical |
If it is not possible to evaluate the information by CVSS v 3.0 metrics, other metrics for information evaluation are used (for example NCISS metrics) which are internationally recognized and used in evaluation of cyber-relevant information
We can divide the respective information in order of their importance into four categories according to which the respective documents with the warning content are published:
| Severity | CVSS Score (if applicable) | Warning Form |
| Low | 0.1 – 3.9 | Announcement on Webpage |
| Medium | 4.0 – 6.9 | Weekly Security Bulletin |
| High | 7.0 – 8.9 | Weekly Security Bulletin |
| Critical | 9.0 – 10.0 | Prompt Security Warning |
Announcement on Webpage contains the information with low importance which does not fundamentally affect the cyber security; anyway it is important to inform of such information.
Weekly Security Bulletin contains a set of warnings and alerts which may have an impact on the status of cyber security. The bulletin is published once a week and contains a set of information with medium and high importance from the previous week. The archive of security bulletins can be found on SK-CERT webpage.
Security Warning contains a specific warning with a critical importance which may have a fundamental impact on the status of cyber security at the national and also international level. It is issued, if necessary, in order to ensure an early warning of SK-CERT constituency as well as other potentially attacked entities. The security warning is immediately published on the SK-CERT website in the relevant section.
