Network Time Protocol (NTP) is the specification that computers use to ensure accuracy of their internal clocks. Hackers can exploit the NTP to perform man-in-the-middle attacks that reset clocks to times that are months or years in the past.
Commvault automatically tracks the system time, and detects clock resets and time changes on the CommServe server. When such a change is detected, the system temporarily stops data aging jobs. The system then asks the user to confirm the time change via email, or via an alert in the Process Manager.
Note
If the CommServe server is powered off for a prolonged period of time, the system may send emails and alerts.
Procedure
-
If you receive an email that alerts you that a time change is detected, check the system time and then restart services using the Process Manager.
-
If you receive an alert in the Process Manager, follow the instructions that appear on the screen to confirm that the system time is correct.
