✓
Enabling automated vulnerability scanning upon image push
Securing container registries involves implementing role-based access control, enabling vulnerability scanning on push, and enforcing image signing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enabling automated vulnerability scanning upon image push
Why this is correct
Scanning images immediately upon upload ensures vulnerabilities are identified before distribution.
- ✓
Enforcing role-based access control (RBAC) on registry repositories
Why this is correct
Restricting who can push and pull images prevents unauthorized code injection into registries.
- ✗
Storing registry admin credentials in plaintext inside Dockerfiles
Why it's wrong here
Hardcoding credentials in Dockerfiles exposes sensitive keys in image layers.
- ✗
Allowing anonymous write access to public repositories
Why it's wrong here
Allowing anonymous write access permits anyone to tamper with or replace container images.
- ✓
Using image signing and verification (e.g., Notary or Cosign) to guarantee artifact integrity
Why this is correct
Image signatures verify that images have not been tampered with since being built and signed.

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 |
