Defensive Alignment: Familiarity with MITRE ATT&CK, threat detection engineering, SIEM/EDR rule development, or SOC operations.
Low-Level Knowledge: Coursework or practical experience in reverse engineering, assembly, or binary analysis.
Defense / Government Experience: Prior experience supporting DoD or government systems and working with classified data handling procedures.
