These are security elements that are core features of using Nix(OS).

~~=== Obscurity of Nix store ===~~

In a vanilla NixOS system, the typical [https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard Linux filesystem hierarchy] is, in large part, replaced with the Nix store's [[User Environment|user environments]]. This means that some malware which might rely on finding system tools in particular places might fail. This is a form of [https://en.wikipedia.org/wiki/Security_through_obscurity security through obscurity] and is only a minor layer of protection.

=== Effort to isolate runtime search paths ===

In general, there is an effort to avoid [~~https~~:~~//en.wikipedia.org/wiki/~~Rpath rpath] collisions across users [https://github.com/NixOS/nix/commit/eba840c8a13b465ace90172ff76a0db2899ab11b].

=== Data integrity and authenticity ===

The core installation resources for Nix(OS) have [~~https~~:~~//en.wikipedia.org/wiki/~~SHA-2 SHA256] checksums which are [~~https~~:~~//en.wikipedia.org/wiki/~~GNU_Privacy_Guard GPG] signed by the [https://nixos.org/download.html#nix-verify-installation Nix team] for authenticity. Within the installation data are all the SHA256 checksums for packages that were available within Nixpkgs at build time.

The core installation resources for Nix(OS) have [[wikipedia:SHA-2|SHA256]] checksums which are [[wikipedia:GNU_Privacy_Guard|GPG]] signed by the [https://nixos.org/download.html#nix-verify-installation Nix team] for authenticity. Within the installation data are all the SHA256 checksums for packages that were available within Nixpkgs at build time.

All packages which are pulled into your Nix system via Nixpkgs derivation builds are checked against SHA256 checksums which are already available on your local system (and should be traceable to the signed core Nix install materials).
