While Teramind provides security updates for its server and web interface, you may wish to keep it up to date with the rest of the underlying Operating System (Debian Linux). To do so, you can run the following commands, as the root user. Contact Teramind support for root access to your server.
As a user, you are responsible for applying updates and patches to the underlying Debian OS of your Teramind server. Regularly updating your OS is crucial for maintaining system security and performance.

Running your Teramind appliance on an outdated OS, such as Debian 8, exposes your system to potential vulnerabilities. To mitigate these risks, upgrading your platform is strongly advised, with a preference for deploying a new server.
Best Practices for Maintaining and Upgrading the Teramind Appliance's Operating System
Connect to your Debian system via SSH or the hypervisor console, and escalate to root privileges. Once you are in the terminal, enter the following commands:
If your Teramind appliance is running on an outdated OS, such as an older version of Debian, we recommend deploying a new Teramind server and migrating your data instead of performing an in-place OS upgrade. This approach ensures a cleaner deployment and minimizes compatibility risks.
grep security /etc/apt/sources.list | tee /etc/apt/security.sources.list
apt-get update
apt-get upgrade -o Dir::Etc::SourceList=/etc/apt/security.sources.list
Press “Y” and “Enter”. Security updates will be installed and your system will be up to date.
To check and apply updates at a later stage do this:
apt-get update
apt-get upgrade -o Dir::Etc::SourceList=/etc/apt/security.sources.list
Recommended Practices for Deployment and Upgrades
Deploy a New Server: For outdated systems, set up a new Teramind server and migrate your data to ensure a clean and secure environment.
Regularly Apply Updates: Stay proactive by applying Debian OS updates and patches as they become available.
Leverage Support Resources: Use Teramind's documentation and remote assistance services to address any challenges during the update or migration process.
Monitor System Security: Regularly review your system's security posture and address any vulnerabilities promptly.
