Beaconing
The regular check-in traffic a compromised machine sends to its command and control server.
Implants call home on a schedule, often with deliberate randomness added so the pattern is less obvious. Even so, the rhythm is unlike human browsing, which is bursty and stops overnight.
Because the traffic is usually encrypted, detection focuses on timing, destination reputation, and volume rather than content. It is one of the few reliable ways to spot a quiet intruder before they act.
Where this comes up
Beaconing sits inside our cybersecurity and threats work. If you are trying to work out what this means for your own environment rather than in the abstract, that is the page worth reading next, and a short call will get you a straight answer faster than either.
