V2 adds several new important Trojan Detection features with a big reduction in the overall impact on a running kernel. 1.Cryptographic hash checking and filtering all files loaded through the memory map call mmap which covers: -Shared libraries -Loadable kernel modules 2.Activation very early in the boot cycle to provide warnings against Trojan files waiting to execute at boot time before the secure level is raised. 3.Improved efficiency in terms of system rescues used, providing very affordable increased security capabilities. 4.Cryptographic hash checking and filtering the Execve call including script files and an associated interpreter as the original reference version did yet utilizing the more efficient techniques from the V2 code.
