Secure input and output handling is a type of what, which protects computers from theft or damage?
Secure input and output handling Secure input and output handling are secure programming techniques designed to prevent security bugs and the exploitation thereof.
Secure communication Secure communication is when two entities are communicating and do not want a third party to listen in. For that they need to communicate in a way not susceptible to eavesdropping or interception. While standard secrecy methods such as cryptography protect the contents of the message from being accessed by unauthorized users, covert communication conceals the existence of the communication to prevent unauthorized users to detect the communication. Secure communication includes means by which people can share information with varying degrees of certainty that third parties cannot intercept what was said. Other than spoken face-to-face communication with no possible eavesdropper, it is probably safe to say that no communication is guaranteed secure in this sense, although practical obstacles such as legislation, resources, technical issues (interception and encryption), and the sheer volume of communication serve to limit surveillance.
