9.8.3 Network and Security
For maximum security, Asymptote recommends that you connect the system to your
intranet only, not exposing it to the Internet. This minimises the small risk that the Linux
OS could present a security vulnerability to your network. If the system is connected with
direct access to the Internet, regular maintenance of the OS software packages will
ensure that any vulnerabilities discovered by the Linux community are patched.
9.8.4 Software maintenance
If connected with direct access to the internet, we recommend that the Linux OS is kept
up to date monthly with the:
$sudo apt-get update
$sudo apt-get upgrade
standard package manager commands to maintain security of the system.
The VIA Freeze ™ software is maintained by Asymptote. As new VIA Freeze ™ software is
released, Asymptote will contact you by email to make you aware of the new software.
The update process requires a user to load the patch onto a USB device, connect it to
the system, and to log in as an admin user and access the software update page.
