ISC2 CC Practice Question: Which TWO are examples of technical access…
Which TWO are examples of technical access controls?
⚠ Common exam trap
ISC2 often tests the distinction between administrative, physical, and technical controls, and the trap here is that candidates confuse 'security awareness training' or 'security policies' as technical controls because they are part of a security program, but they are not implemented through technology or code.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Encryption
Encryption (C) is a technical access control because it uses cryptographic algorithms (e.g., AES-256, RSA) to transform data into an unreadable format, ensuring that only authorized entities with the correct decryption key can access the original information. This enforces confidentiality and access restrictions at the data level, independent of user behavior or administrative policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Security awareness training
Why it's wrong here
Training is an administrative control.
- ✗
Security policies
Why it's wrong here
Policies are administrative controls.
- ✓
Encryption
Why this is correct
Encryption is a technical control that protects data confidentiality.
- ✗
ID badges
Why it's wrong here
ID badges are physical controls.
- ✓
Access control lists
Why this is correct
ACLs are a technical mechanism to enforce permissions.

Symmetric Encryption Algorithm Comparison
| Algorithm | Key Size | Block Size | Status | Notes |
|---|---|---|---|---|
| AES-128 | 128-bit | 128-bit | Current standard | NIST approved; WPA3, TLS |
| AES-256 | 256-bit | 128-bit | Current standard | Preferred for sensitive / govt data |
| 3DES | 112-bit effective | 64-bit | Deprecated (2023) | Replaced by AES |
| DES | 56-bit | 64-bit | Broken | Cracked in < 24 h; never deploy |
| ChaCha20 | 256-bit | Stream cipher | Current | TLS 1.3, WireGuard |
