In Samsung GALAXY S4, Samsung KNOX provides container management and policies compliant with the U.S. Department of Defense (DOD) mobile OS security requirements guide (SRG). Offering SRG-compliant, robust security, Samsung KNOX protects your mobile device at the operating system level through a three-pronged approach:
Customizable Secure Boot (CSB)* is the first line of defense, ensuring that only verified operating systems and software load during the start-up process.
TrustZone-based Integrity Measurement Architecture (TIMA) protects, monitors and verifies the integrity states of the kernel with policy driven actions in response to kernel or boot loader violations.
Security Enhancements for Android (SE for Android) is an NSA-developed security technology integrated in Android to isolate applications and data in different domains based on confidentiality.
