andlock’s goal is to make it possible for Linux applications to sandbox themselves. On Linux, many traditional access control mech- anisms are only available to the system administrator, which do not follow the principle of least privilege. As a result, sandboxing policies were created independently of an actual program execution, leading to unnecessarily broad policies. With Landlock, unprivileged processes can safely create sandboxing policies well-tailored to the expected needs of a running application. Landlock also solves the organizational aspect of keeping policy and software in sync with each other, by putting the policy definition and maintenance in the developer’s hands.
