+<title>Security</title>
+
+<para>Nix has two basic security models.  First, it can be used in
+“single-user mode”, which is similar to what most other package
+management tools do: there is a single user (typically <systemitem
+class="username">root</systemitem>) who performs all package
+management operations.  All other users can then use the installed
+packages, but they cannot perform package management operations
+themselves.</para>
+
+<para>Alternatively, you can configure Nix in “multi-user mode”.  In
+this model, all users can perform package management operations — for
+instance, every user can install software without requiring root
+privileges.  Nix ensures that this is secure.  For instance, it’s not
+possible for one user to overwrite a package used by another user with
+a Trojan horse.</para>
