- Patterns and frequencies of API calls
3. Custom Code Elements
Review any customisations, including theme changes, custom checkout processes, unique features, and JavaScript implementations.
Security Check Review
Evaluate your current security measures to identify any gaps. Here’s a quick comparison:
| Security Measure | Current Status | Required Level |
|---|---|---|
| Two-factor Authentication | Mandatory/Optional | Mandatory for all admin users |
| Password Policies | Basic/Advanced | Advanced with regular updates |
| API Access Controls | Limited/Full | Limited with regular reviews |
| Session Management | Standard/Enhanced | Enhanced with session timeout rules |
| Data Encryption | Transport/Storage | Both during transport and storage |
Identify where your current measures fall short of the required levels. These findings will shape your testing strategy, guiding both automated scans and manual testing to ensure your security approach stays on track.
