Ensure time synchronization is in use

СредњаНиво 1Ручни прегледcos

Опис

System time should be synchronized between all systems in an environment. This is typically done by establishing an authoritative time server or set of servers and having all systems synchronize their clocks to them. Time synchronization is important to support time sensitive security mechanisms like Kerberos and also ensures log files have consistent time records across the enterprise, which aids in forensic investigations.

Ова препорука се не може проверити аутоматски. Скенирање је наводи са овим упутствима када проследите --include-manual.

On physical systems or virtual systems where host based time synchronization is not available verify that chrony is installed with the following command: # grep '\"name\": \"chrony\"' /etc/cos-package-info.json "name": "chrony", On virtual systems where host based time synchronization is available consult your virtualization software documentation and verify that host based synchronization is in use.

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

On physical systems or virtual systems where host based time synchronization is not available update to an image that comes with chrony package installed. On virtual systems where host based time synchronization is available consult your virtualization software documentation and setup host based synchronization.
