Session Management is the process of initiating, maintaining, controlling, and terminating an interaction between a user and a system over a defined period. It governs how access is maintained after a user is authenticated and ensures that sessions are monitored, time-bound, and secured against misuse. Effective session management includes functions such as timeouts, re-authentication, activity logging, and the ability to supervise or terminate sessions in real time, all essential for maintaining secure, auditable user activity across IT and OT systems.
Once a user gains access to a system, their session becomes a potential point of vulnerability. Poorly managed sessions can lead to unauthorized access, session hijacking, lateral movement, and data exposure, especially in critical infrastructure environments where high-privilege users may interact with sensitive industrial systems.
Effective session management enforces least privilege, ensures traceability, and limits the duration and scope of access. It supports operational oversight by enabling organizations to record activity, monitor behavior, and detect anomalies during live sessions. This visibility is essential not only for incident response but also for meeting compliance mandates such as NERC CIP, IEC 62443, TSA SD02E, NIS2, and OTCC-1:2022, all of which require organizations to track and control privileged sessions.
In OT environments, where third-party access is common and cyber-physical systems are highly sensitive, session management becomes a frontline defense ensuring that all interactions are authorized, monitored, and terminated when no longer needed.
Xona delivers robust session management capabilities purpose-built for critical infrastructure environments. All sessions initiated through Xona’s disconnected access platform are proxied, isolated, and fully auditable. This architecture ensures that users, whether internal staff or third-party vendors, can interact with OT systems without direct network connectivity, minimizing risk.
Xona provides real-time session monitoring, allowing administrators to observe, intervene, or terminate sessions on demand. This includes the ability to moderate access, require dual approvals, or enable session takeover in emergency situations. Each session is also recorded with full video and metadata, enabling post-session review for compliance, incident analysis, and training.
Time-based controls, automatic session expiration, and integration with identity providers (e.g., SAML, LDAP, AD) further ensure that sessions are only active when needed, by authorized users, under approved conditions. Whether managing access during a scheduled update or responding to a system alert, Xona empowers organizations with real-time control, visibility, and compliance readiness.
