Best Practices with TimeKeeper® SourceCheck (2016)
The TimeKeeper ‘SourceCheck’ feature is an analytics and automated threat detection tool that allows TimeKeeper to detect bad time sources and switch away from them. Bad time can come from misconfiguration, equipment and software failures or intentional time based attacks. SourceCheck can detect and defeat them.
SourceCheck combines a multi-source stochastic analysis, protocol verification, and source voting to detect outlier time sources. Each time source gets a vote for the correct time. TimeKeeper then looks for patterns over an interval to see if a second source is more in sync with a critical mass of sources.
