R11 — Lateral Movement

Q: How do security teams mitigate Lateral Movement?

In CISO Game, Lateral Movement is reduced by Detection (40%), Prevention (30%), Identity (30%) subscores. Real-world programs use the same control families, with category investments such as Mid-Tier EDR (industry standard), Premium XDR (full endpoint+identity), Open-Source SIEM (self-hosted).

Q: Why does Lateral Movement matter to a CISO?

Severity 8 (Major). Lateral movement is what turns a single compromised endpoint into an enterprise-wide incident. Network segmentation, micro-segmentation (Zero Trust), and credential hygiene (no shared local admin passwords, LAPS, no domain admin reuse) are the structural mitigations. EDR with strong behavioral detection is the alarm system that catches it in flight.
