Episode 49 — A.7.5–7.6 — Environmental threats; Working in secure areas
A.7.5 addresses protection against environmental threats—natural, accidental, or man-made—that could disrupt facilities or damage information assets. For the exam, focus on risk-based safeguards such as fire detection and suppression appropriate to equipment, water leak detection, surge protection, redundant power paths, and climate control to maintain temperature and humidity within safe ranges. Site selection should account for flood plains, seismic zones, and proximity to external hazards, with documented justifications and compensating measures where relocation is impractical. Candidates must connect environmental protection to business continuity dependencies: generators and fuel logistics, maintenance schedules, and periodic tests with records to show readiness and reliability over time.
A.7.6 governs working in secure areas, ensuring that activities conducted within restricted zones do not compromise controls. Expectations include enforced access rules, prohibition of recording devices where appropriate, supervised contractors, and clear desk/screen behavior even inside the perimeter. Procedures should cover visitor escorting, tool and media control, and background checks for staff assigned to these areas. Pitfalls include complacency—assuming the perimeter alone is sufficient—and ad hoc exceptions for convenience. Effective programs use check-in/check-out logs for tools and media, random spot checks, and camera-informed patrols; they also brief personnel on scenario-specific etiquette, such as shielding console outputs or masking indicators during maintenance. Candidates should be ready to cite evidence such as maintenance tickets with escort records, secure area SOPs, and environmental system test logs, demonstrating that resilience and discipline extend beyond walls and locks to daily behavior and preventive maintenance.
