Fortify
=======
[](https://pkg.go.dev/git.ophivana.moe/security/fortify)
[](https://goreportcard.com/report/git.ophivana.moe/security/fortify)
Lets you run graphical applications as another user in a confined environment with a nice NixOS
module to configure target users and provide launchers and desktop files for your privileged user.
Why would you want this?
- It protects the desktop environment from applications.
- It protects applications from each other.
- It provides UID isolation on top of the standard application sandbox.
There are a few different things to set up for this to work:
- A set of users, each for a group of applications that should be allowed access to each other
- A tool to switch users, currently sudo and machinectl are supported.
- If you are running NixOS, the module in this repository can take care of launchers and desktop files in the privileged
user's environment, as well as packages and extra home-manager configuration for target users.
If you have a flakes-enabled nix environment, you can try out the tool by running:
```shell
nix run git+https://git.ophivana.moe/security/fortify -- -h
```
## Module usage
The NixOS module currently requires home-manager and impermanence to function correctly.
To use the module, import it into your configuration with
```nix
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.05";
fortify = {
url = "git+https://git.ophivana.moe/security/fortify";
# Optional but recommended to limit the size of your system closure.
inputs.nixpkgs.follows = "nixpkgs";
};
};
outputs = { self, nixpkgs, fortify, ... }:
{
nixosConfigurations.fortify = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
fortify.nixosModules.fortify
];
};
};
}
```
This adds the `environment.fortify` option:
```nix
{ pkgs, ... }:
{
environment.fortify = {
enable = true;
stateDir = "/var/lib/persist/module/fortify";
users = {
alice = 0;
nixos = 10;
};
apps = [
{
name = "chromium";
id = "org.chromium.Chromium";
packages = [ pkgs.chromium ];
userns = true;
mapRealUid = true;
dbus = {
system = {
filter = true;
talk = [
"org.bluez"
"org.freedesktop.Avahi"
"org.freedesktop.UPower"
];
};
session =
f:
f {
talk = [
"org.freedesktop.DBus"
"org.freedesktop.FileManager1"
"org.freedesktop.Notifications"
"org.freedesktop.ScreenSaver"
"org.freedesktop.secrets"
"org.kde.kwalletd5"
"org.kde.kwalletd6"
];
own = [
"org.chromium.Chromium.*"
"org.mpris.MediaPlayer2.org.chromium.Chromium.*"
"org.mpris.MediaPlayer2.chromium.*"
];
call = { };
broadcast = { };
};
};
}
{
name = "claws-mail";
id = "org.claws_mail.Claws-Mail";
packages = [ pkgs.claws-mail ];
gpu = false;
capability.pulse = false;
}
{
name = "weechat";
packages = [ pkgs.weechat ];
capability = {
wayland = false;
x11 = false;
dbus = true;
pulse = false;
};
}
{
name = "discord";
id = "dev.vencord.Vesktop";
packages = [ pkgs.vesktop ];
share = pkgs.vesktop;
command = "vesktop --ozone-platform-hint=wayland";
userns = true;
mapRealUid = true;
capability.x11 = true;
dbus = {
session =
f:
f {
talk = [ "org.kde.StatusNotifierWatcher" ];
own = [ ];
call = { };
broadcast = { };
};
system.filter = true;
};
}
{
name = "looking-glass-client";
groups = [ "plugdev" ];
extraPaths = [
{
src = "/dev/shm/looking-glass";
write = true;
}
];
extraConfig = {
programs.looking-glass-client.enable = true;
};
}
];
};
}
```
