Techniques for validation and controlled execution of processes, codes and data: A survey

Various security mechanisms are available to validate, authenticate and permit codes, data and scripts for executing in a computing device. Accordingly, different techniques and tools have been developed to preserve integrity and confidentiality at the process, protocol, system and communication levels. For example, Trusted Platform Module, Intel Trusted Execution Technology and Windows Vista Kernel Mode security ensure system level integrity and security, whereas, Digital Signature, Code Signing, Watermarking, Integrity Checker and Magic Cookies address integrity of data and executables in transit. A brief survey of these techniques is described here with how these techniques help to secure computing environment.
