Landlock Restricts App Access (28 chars)
Summary
These security mechanisms enhance system integrity by allowing granular control over application behavior and enabling resilient off-grid communication.
- LSM Introduced Landlock LSM, active since Linux 5.13, enables explicit runtime policies restricting application resource access 1.
- Mesh Networking Meshtastic utilizes LoRa radios to build decentralized, private mesh networks using a three-step device setup process 2.
- Policy Enforcement The core function of Landlock is to allow processes to self-limit system call access before execution 1.
- 5.13 - Minimum Linux kernel version required for Landlock LSM support 1.
- Three - The number of distinct steps required for a user to configure a Meshtastic device 2.
Key Moments
