A graphical representation of the onion mannequin of Defense in Depth, an idea in Info Security. The author compiles his publications utilizing one in every of two algorithms: the LPC parameters substitution for secret speech data hiding based on filter similarity (LPC-IH-FS) 24, and knowledge extraction with blind detection-based mostly minimum mean square error (MES-BD) 25. The proposed algorithm adopts the speech synthesizer in the speech coder. Speech embedding and coding are synchronous; that’s, the fusion of secret speech info knowledge and speech coding. It will possibly embed dynamic secret speech information information bits into unique carrier speech information, with good efficiency in steganography and good high quality in output speech. It’s sensible and effective in contrast with the prevailing strategies, thus real-time communication requirements might be met.
Protection in depth is an idea utilized in Info safety wherein multiple layers of safety controls are placed throughout an info expertise system. Its intent is to provide redundancy within the occasion a safety control fails or a vulnerability is exploited that may cover points of personnel, procedural, technical and physical security all through the system’s life cycle.
While protection in depth is still a crucial component of effective security, the approach and methods have changed. It is nonetheless true that no single measure can shield a company however assuming for a second that it does exist, would we wish to use it? The reply is absolutely not. If there was one single system that made you safe, what number of gadgets would an attacker have to defeat to be successful. The proper answer is one. technology information Therefore we want a number of levels of safety out of necessity, figuring out that any single measure might be compromised. While we hope we never get compromised, if some of our safety is compromised, it should be designed in a method that we can detect it before it gets to our vital info.
