A county IT team needs device clocks to agree so syslog and AAA records correlate, and they want protection against rogue time sources. Which practice best meets both goals?
Select an answer to reveal the explanation.
Short Explanation
Logs without matching clocks are like police reports with three different time zones. Point everyone at a trusted NTP source and authenticate it so a prank time server cannot rewrite your timeline. That is how county-wide correlation actually works.
Full Explanation
NTP synchronizes device clocks for coherent logging, certificates, and AAA timelines. Authentication (or equivalent trust controls) reduces risk from spoofed time servers. Manual annual sets and disabled timestamps defeat correlation. Blindly trusting arbitrary public pools without organizational trust controls weakens the civic time domain.
