Adopting least-privilege access is becoming a standard requirement under cybersecurity frameworks like NIST 800‑171 and CMMC. It means giving users the minimum permissions needed to do their jobs—but many organizations implement it unevenly, decreasing its effectiveness.
Common Shortfalls:
Users granted broad access "just in case"
Admin accounts used for routine work
Permissions not regularly reviewed or revoked
These gaps increase risk, especially when handling sensitive data like Controlled Unclassified Information (CUI). They also complicate compliance audits, as assumptions about who had access—and when—can lead to findings.
One viable strategy is to combine least-privilege with system segmentation. For example, isolating CUI processes into a CMMC enclave ensures that high-security controls go only where needed. Access to the enclave can be strictly controlled, logging can be detailed, and permissions managed tightly—while the rest of the environment stays more flexible.
Applying least-privilege in context, using tools and architecture to reinforce it, helps contractors reduce overall risk and simplify compliance efforts. It’s not just about policy—it’s about embedding the right access controls into your systems’ design.
