# Security
|
|||
|
|
|
|||
|
|
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 root) who performs all package
|
|||
|
|
management operations. All other users can then use the installed
|
|||
|
|
packages, but they cannot perform package management operations
|
|||
|
|
themselves.
|
|||
|
|
|
|||
|
|
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.
