ISC Systems Security Engineering Foundations Practice Question
During the 'Engineering Process Integration' phase, an ISSE identifies that the legacy system lacks support for modern TLS 1.3 encryption. What is the most appropriate engineering response?
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
✓
Document the risk and implement compensating controls
The ISSE should perform a gap analysis to determine if a compensating control can mitigate the risk until the legacy system can be upgraded or replaced.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Forcibly inject TLS 1.3 into the binary
Why it's wrong here
This is dangerous and likely to cause system instability.
- ✗
Ignore the finding because it is a legacy system
Why it's wrong here
Legacy status does not exempt a system from risk management requirements.
- ✓
Document the risk and implement compensating controls
Why this is correct
Compensating controls provide necessary security when native support is missing.
- ✗
Immediately shut down the system
Why it's wrong here
Shutting down may cause excessive operational disruption; risk management is preferred.
