Smack (full name: Simplified Mandatory Access Control Kernel) is a Linux kernel security module that protects data and process interaction from malicious manipulation using a set of custom mandatory access control (MAC) rules, with simplicity as its main design goal.[1] It has been officially merged since the Linux 2.6.25 release,[2] it was the main access control mechanism for the MeeGo mobile Operating System.[3][4] It is also used to sandbox HTML5 web applications in the Tizen architecture,[5] in the commercial Wind River Linux solutions for embedded device development,[6][7] in Philips Digital TV products.,[8] and in Intel's Ostro OS for IoT devices.[9]

Between 2016-2021, Smack was required in Automotive Grade Linux (AGL) where it provided in association with other Linux facilities the base for the AGL security framework. [10] [11] Since then the Project migrated to SELinux.
