Hi Miran,
Do you mean the security log in Event Viewer?
System restore will not revert any logs to previous point, also it would cause risk for security if it is possible to revert to previous point.
I tested on my side after system restore on virtual device, it move on as before without revert back. The system restore action will be recorded in Event Viewer\Windows logs\Application.
If my information is useful for you, please mark it as answer.
Bests,
