CISSP Fix

This centaury stands on the edge of new modern methods of attacks and advancement in the speed of computation, which taken over the best known secure secret-key algorithm such as DES, Digital Encryption Standard conquered the world of cryptography for centuries. A 40 bit version of the DES algorithm can be easily cracked by any modern computer and a 56 bit can be broken by any cheaply available Super Computer or by a simple beo-wulf cluster. That poses a security threat and people have developed, developing various other algorithms like 3DES also known as Triple DES etc, The NIST and NSA plays an important role in deciding the algorithms. They analyze and recommend the algorithm for usage.

“Necessity is the Mother of all Inventions”, sophistication of digital environment lead to the discovery of Computer Forensics. Computer Forensics is an investigative process of collecting and examining of electronic evidence to form a structured report which can be produced in a court as a evidence. Computer Forensic is introduced when crime is facilitated either by using computer or on Computer or Network itself. Computer Forensic also deals with the issue, such as Privacy, Copy Infringement, and Software ownership. For the collection of Electronic Evidence, it is required to follow certain pre-established procedure and steps, which ensures the identity of culprit. By following such methodologies, computer crime investigation can be done effectively and efficiently.
