How to Protect NTP Servers from Cyberattacks? [closed]
I am a beginner in cyber security and they asked me to build a secure architecture for time servers. I have 3 three NTP servers on Ubuntu, each configured with chrony, nptd, NTP (In order to test them and find out which of them is the fastest and more secure).
Any recommendations about a secure NTP architecture?
