Using Mono-Alphabetic Substitution to Secure Against Threats and Risk in Information Technology
G. I. Ighalo · IOSR Journal of Electronics and Communication Engineering · 2013
The awareness the world over on information technology (IT) is a welcome development but calls for great care and concern.This is so as there are out there, many people with evil minds who see nothing good that they would not capitalize on.There are persons who would want to create problems to make systems not workable while there are others who would want to steal or destroy such systems.This write-up therefore tries to analyse information technology systems, looking at all possible threats and risks and how to combat or make such systems secure.In doing this, very simple yet difficult to guess systems software are designed to check evil practices such that would-be risk or threat persons would find it difficult to use.Encryption methods that use either the substitution or transposition principles are designed to protect such threats or risk.The written program will encipher and decipher information such that the integrity of the information is protected.This method chooses this enciphering and deciphering such that any user can easily learn and design his/her own keys which are not stored in the system.Other measures that will check threats and risks are proposed and counter measures that are involved with access control are provided.A better risk management and training are proposed.
