# Limit guest's active session life span

Use the **glide.guest.active.session.life\_span** property to control the duration of an active guest's HTTP sessions.

The **glide.guest.active.session.life\_span** system property enforces a maximum lifespan on active guest HTTP sessions, regardless of session inactivity. The configured value is in minutes. A value of `0` disables the lifespan limit entirely, allowing sessions to persist until the inactive timeout fires. Guest users are unauthenticated users who access the instance without logging in.

Set the **glide.guest.active.session.life\_span** system property to `720`.

Security risk

</td><td>

-   Severity score: 4.2
-   CVSS score: Medium
-   Security risk details: A larger maximum lifespan could allow an attacker to persist a stolen session for longer, increasing the scope of a security incident.

</td></tr><tr><td>

Functional impact

</td><td>

This configuration enforces max life-span on active guest HTTP sessions irrespective of inactive timeout. The configured value is in minutes. A value of zero disables the lifespan limit entirely. The max life-span should be more than the inactive timeout **glide.ui.session\_timeout** \(default 30 minutes\).
