Security updates for Call Recorder Apresa

The Apresa recording solution is built on top of the Debian Linux distribution. The security of the system depends on the security of both Debian and Apresa.

Debian Security Updates

To install security updates for the Debian OS, it is needed that Apresa has outbound internet access. Debian security updates can be installed automatically. This can be configured in the web interface since version 10.1.0 of Apresa.

• Log in as administrator (admin) in the web interface
• Open the Tools menu, select System
• Click the Software update button
• Next to Automatic security updates, click on Configure.
• Click to Install the prerequisites (if not installed yet), and set the frequency of update checks
Note: If the prerequisites fail to install, check if Apresa has outbound internet access, and if the Server for installing Debian software is configured correctly.

Apresa will try to send an email to the configured admin email address about the security updates that were performed or are pending (requiring reboot). Kernel updates will require a reboot.
Note: If you are using Synway cards (for recording analog, digital TDM, etc.), then updating the kernel might cause the driver to no longer to load, and will require an updated driver.
Alternatively, security updates can be installed manually on the command line (using apt-get).
