What is the reasoning behind the need for cryptography within an organization? First, explain why cryptography is needed based on the potential vulnerabilities present in the absence of an encrypted network. Solution Need for cryptography: The most basic and foremost reason for the need of cryptography is security! a.) cryptography ensures that the data remains confidential-the data which is not meant for the public eye is kept hidden. b.) And it allows authorization for those users who have the permission to perform a function. Does not allow any unauthorised users to enter. c.) It makes sure that the information which is being transmitted is authenticated /original andfree of all manipulations/changes. d.) assures against a party that denies data or comunicationnwhich was started by them -this is nonr repudiation. In the absence of an encrypted network,crptography is used to remove the vulnerabilities which can a weakness in technology or security policy or the configuration.When all others fail to provide to the required level of security then cryptography steps in to handle these vulnerabilties. .
