CND Endpoint Protection Practice Question
A security architect is designing a Linux endpoint hardening baseline. Which THREE of the following configurations help enforce Mandatory Access Control (MAC) and restrict process privileges? (Choose THREE)
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
✓
Enforcing SELinux in targeted or multi-category security (MLS) mode
Mandatory Access Control frameworks like SELinux and AppArmor, combined with proper kernel parameter tuning (sysctl), enforce least privilege.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enforcing SELinux in targeted or multi-category security (MLS) mode
Why this is correct
SELinux enforces granular least-privilege security policies at the kernel level.
- ✗
Setting all user home directory permissions to world-writable (chmod 777)
Why it's wrong here
World-writable home directories allow any local user to tamper with others' files and scripts.
- ✗
Disabling all audit logging and accounting daemons
Why it's wrong here
Disabling audit mechanisms removes visibility into security policy violations.
- ✓
Enforcing AppArmor profiles for critical network-facing daemons
Why this is correct
AppArmor confines applications to restricted sets of system resources and files.
- ✓
Configuring kernel sysctl parameters to restrict core dumps and kernel pointer leaks (e.g., kptr_restrict=2)
Why this is correct
Tuning sysctl parameters hardens the kernel against memory disclosure and crash analysis exploitation.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
