To mitigate the risk posed by long-running Google Cloud CLI sessions, it is essential to enforce a reauthentication frequency. This ensures that users must periodically reauthenticate, reducing the window of opportunity for an attacker to exploit an open session. Setting the reauthentication frequency to one hour forces users to reauthenticate after this period, thereby limiting the duration an attacker can use a compromised session.
* Access Google Cloud Console: Log in to your Google Cloud Console using your admin credentials.
* Navigate to Security Settings: Go to the "Security" section of the Cloud Console.
* Set Session Control: Under the session management settings, locate the "Reauthentication frequency" setting. This controls how often users must reauthenticate.
* Configure Reauthentication Frequency: Set the reauthentication frequency to "1 hour". This configuration will force users to reauthenticate every hour, thus limiting the duration of each session.
* Save Changes: Confirm and save your changes. This setting will now apply to all users, ensuring that open sessions are minimized to a duration of one hour.
