DSX Dynamic Security Extension

A proprietary technology that is patented and works in the following way. The operating system has a system call (or vector) table that contains memory address pointers for each system call. These pointers point to a location in memory where the actual kernel code of the system calls resides. DSX stores the address pointers for the security-sensitive system calls and then redirects these pointers to the corresponding SECURED system call code, which is located elsewhere in memory.
