SDSI Risk Events And Requirements Practice Question
Following a ransomware incident, an architect must modify the network segmentation strategy. What is the most effective approach to mitigate lateral movement using Cisco TrustSec?
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
✓
Implement SGT-based micro-segmentation at the access layer to enforce policies based on identity rather than IP.
TrustSec SGTs (Scalable Group Tags) allow for dynamic policy enforcement regardless of IP address, making it ideal for mitigating lateral movement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy extended ACLs on every core switch port to block peer-to-peer traffic.
Why it's wrong here
Static ACLs are operationally expensive and difficult to maintain in dynamic environments.
- ✗
Configure static port-security across the entire enterprise to prevent unauthorized devices.
Why it's wrong here
Port security prevents unauthorized access but does not address lateral movement between authorized segments.
- ✓
Implement SGT-based micro-segmentation at the access layer to enforce policies based on identity rather than IP.
Why this is correct
SGTs provide identity-based access control, effectively restricting lateral movement.
- ✗
Transition all physical cabling to private VLANs without leveraging SGTs.
Why it's wrong here
Private VLANs provide L2 isolation but lack the granular policy capabilities of SGTs.
