What is Access Control Standards?
Access control standards are formalized guidelines and technical specifications that define how organizations should manage, restrict, and monitor user access to systems, applications, and data. These standards outline best practices for authentication, authorization, role assignment, session management, and auditability to ensure that only authorized individuals can perform specific actions on protected resources. Common access control standards include frameworks such as NIST SP 800-53, IEC 62443, NERC CIP, ISO/IEC 27001, and TSA Security Directives.
Why are Access Control Standards Important?
Access control is a foundational element of cybersecurity. Without it, organizations cannot ensure that users have only the minimum access required to perform their roles, a concept known as least privilege access. In critical infrastructure sectors, where unauthorized access can lead to physical disruption or regulatory penalties, adherence to standardized access control practices is essential.
Access control standards provide a common language and measurable criteria for implementing access policies across complex environments. They address key security principles such as identity-based access, role-based access control (RBAC), multi-factor authentication (MFA), and auditable session management. These standards are also embedded in major regulatory frameworks, including IEC 62443-3-3 SR 1.1–1.3, NERC CIP-004, TSA SD02E, and NIS2, making them critical for compliance.
Following access control standards helps organizations reduce risk, enforce accountability, and demonstrate due diligence during audits or incident investigations.
How Does Xona Help with Access Control Standards
Xona supports compliance with leading access control standards by enforcing secure, policy-driven access to critical systems through its hardened access gateway. It integrates with enterprise identity providers to apply role-based, time-bound, and protocol-specific access controls in line with regulatory requirements.
Xona also provides built-in support for multi-factor authentication, credential vaulting and injection, session recording, and real-time oversight, aligning with technical controls outlined in IEC 62443, NERC CIP, and other frameworks. By isolating user access at the session level and removing the need for direct network connectivity, Xona helps organizations meet access control standards while minimizing attack surface and operational complexity.
