Frequently Asked Questions
What is NTP?
Network Time Protocol keeps device clocks synchronised using a hierarchy of time sources called strata. Accurate time is needed for logging, authentication and correlating events.
Why does time synchronisation matter for security?
Consistent timestamps let you correlate logs across systems and keep protocols like Kerberos working. Unsynchronised clocks make incident investigation unreliable.
What is an NTP amplification attack?
Attackers abuse exposed NTP servers with spoofed requests so large responses flood a victim. This free beginner Codelivly room covers the attack and how to secure NTP.
