<title>Spectrum, a step towards usable secure computing</title>

<body>

<h1>Spectrum — a step towards <em>usable</em> secure computing</h1>

<p>
Spectrum is a project that aims to create a computer operating system,
based on the principle of security by compartmentalization, that has a
lower barrier to entry and is easier to use and maintain than other
such systems.

<p>
User data and application state will be managed centrally, while
remaining isolated, meaning that the system can be backed up and
managed as a whole, rather than mixed up in several dozen virtual
machines.

<p>
The host system and isolated environments will all be managed
declaratively and reproducibly
using <a href="https://nixos.org/nix/">Nix</a>, a purely functional
package manager. This will save the user the burden of maintaining
many different virtual computers, allowing finer-grained resource
access controls and making it possible to verify the software running
across all environments.

<p>
Spectrum is free software, currently under active development.  If you
are interested in <a href="participating.html">participating</a>, we'd
love to have you.

<p>
Funding for Spectrum is provided
by <a href="https://www.ngi.eu/about/ngi-zero/">NGI Zero</a>, an
initiative by the Digital Single Market of the European
Commission.
