Two Hosts, One Problem

Two workstations were flagged by a weekly review for unusual DNS volume. Only one of them is actually a problem. You have the DNS records for both. Decide which host needs a ticket, and be able to say why the other does not.

What you will be able to do

  • Apply the DNS tunnelling signals to two candidates and eliminate one.
  • Justify clearing a host as firmly as escalating one.
  • Recommend a next step proportionate to the finding.
