When you protect something valuable—your house, your phone, or your company’s data—you rely on three broad kinds of safeguards. In cybersecurity (and general risk management), we call them Administrative, Technical, and Physical controls. Think of them as the policy-makers, the tech wizards, and the muscle:
| Category | “Plain-Speak” Role | Simple Examples |
|---|---|---|
| Administrative (a.k.a. Managerial) | Set the rules. These are policies, procedures, and people-based processes that tell everyone what to do and how. | • Security awareness training • Hiring background checks • Password policy that says “change every 90 days” |
| Technical (a.k.a. Logical) | Work the gadgets. Software or hardware that automatically enforces the rules. | • Firewalls that block risky traffic • Multi-factor authentication (codes, biometrics) • Disk encryption |
| Physical | Guard the doors. Tangible barriers that keep intruders or accidents from harming your assets. | • Locks, fences, and badge readers • Surveillance cameras and motion sensors • Fire-suppression systems |
How They Work Together
- Administrative sets expectations “Employees must wear badges at all times.”
- Physical enforces access at the door A security guard and turnstile check for that badge.
- Technical watches the network once you’re inside If someone plugs in an unauthorized USB drive, endpoint protection blocks it.
Real-Life Snapshot: A Company Laptop
- Administrative – Policy says: “Encrypt laptops, and report loss within one hour.”
- Technical – Full-disk encryption and remote-wipe software stand ready.
- Physical – You carry the laptop in a lockable bag; the office has CCTV and keyed doors.
Each layer covers gaps the others can’t. Lose the laptop? Encryption (technical) keeps data secret, and the loss-report rule (administrative) triggers a quick response.
Why This Matters
- Compliance: Regulations like HIPAA or PCI-DSS expect you to address all three areas, not just install fancy software.
- Defense-in-Depth: Attackers often chain weaknesses—a stolen badge (physical) plus a reused password (technical) plus lax off-boarding procedures (administrative). Covering all pillars shrinks their options.
- Balanced Budget: Throwing money only at tech tools ignores cheaper wins like employee training (administrative) or better locks (physical).
Bottom line:
To build real security, stack rules, technology, and tangible barriers together. Leave one pillar out, and you’ll feel it the next time a bad actor—or just plain bad luck—comes knocking.
