Session Management

Identity Access Management

What is Session Management?


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.


Why is Session Management Important?


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.


How Does Xona Help with Session Management?


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.

Frequently Asked Questions

What is the purpose of session management in secure access environments?

Session management helps control how authenticated users maintain access to systems, ensuring sessions are monitored, limited in duration, and terminated when no longer needed to prevent misuse.

What security risks can arise from poor session management?

Improper session management can lead to unauthorized access, session hijacking, privilege escalation, and lateral movement, especially if sessions remain open or unmonitored.

What features are typically included in a secure session management solution?

Key features include session timeout, re-authentication, activity logging, real-time monitoring, session recording, and administrative controls for session intervention or termination.

How does session management support compliance in critical infrastructure sectors?

Standards like NERC CIP, IEC 62443, TSA SD02E, and OTCC-1:2022 require organizations to log and control privileged sessions, enforce time limits, and maintain visibility into user activity for audit and response purposes.

How does Xona enable secure session management in OT environments?

Xona proxies all user sessions through its access gateway, applying time-based controls, real-time monitoring, and video recording to ensure sessions are secure, observable, and fully auditable.

Can administrators intervene during active user sessions with Xona?

Yes, Xona supports real-time session supervision, allowing authorized personnel to monitor, pause, take over, or terminate sessions as needed to maintain operational and security control.
