‘Landrun’: Lightweight Linux Sandboxing With Landlock, No Root Required
Landrun is a new command-line tool designed to enhance the security of unprivileged processes on Linux using Landlock technology. Created by user Zoup, the tool enables users to run potentially risky binaries in a restricted environment without requiring root access or complex setups.
Key Points
- Landrun leverages Landlock, a kernel feature available since version 5.13, to enable sandboxing without root privileges.
- It simplifies restrictions on file and TCP port access using easy command-line flags.
- The tool is inspired by existing solutions like firejail, but promises to offer a more minimalistic and kernel-native approach.
- Landrun is MIT-licensed, making it easy to audit and integrate into systems.
- Its use cases include safely executing untrusted binaries and preventing malicious access to system resources.
