Introduction to system security
--------------------------------

The platform is installed without antivirus software or an index of whitelisted applications. 
The functionality provided by these anti-malware measures is implemented by means of an extensive number of
measures to lock down and harden the operating system, platform system and network.

Security covers areas such as application and operating system security updates, operating system hardening, 
file and application encryption, jailed environments for applications, firewalls, and user security. This 
locked down system ensures that platform users can't install their own packages, binaries, or applications 
on the system to perform any malicious actions or allow the exploitation of vulnerabilities 
(such as Meltdown/Spectre).  


.. note::

   Since the application runs in a virtual environment it is important
   that the underlying VM infrastructure stays up to date to be protected against
   any vulnerabilities that may compromise the Virtual Machine on the infrastructure.
