Access control is a fundamental principle in cybersecurity, ensuring that only authorized individuals can view or manipulate specific systems or data. It limits risk by reducing the number of people with access to sensitive information.
There are different types of access control models: discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC). Each has strengths depending on the organization’s needs. RBAC, for example, grants permissions based on a person’s role rather than individual assignments, streamlining management.
Access control isn’t just about passwords. It includes multifactor authentication (MFA), smart cards, biometric verification, and system-level permissions. Monitoring and regularly reviewing user privileges is also essential to ensure they align with job responsibilities.
In regulated industries, strict access control is often a requirement. For organizations handling Controlled Unclassified Information (CUI), implementing secure environments with tailored permissions is a common best practice.
One solution many turn to is a CMMC enclave. These environments are purpose-built to isolate CUI and apply strict access controls, making it easier to comply with security standards and frameworks like the Cybersecurity Maturity Model Certification (CMMC).
Effective access control reduces internal threats, limits the impact of compromised accounts, and protects valuable digital assets.
