Explanation:

In Information System Security maintaining integrity means that information gets to the intended recipient complete with no alterations. Once information is altered it loses its value, to ensure availability information is available and easily accessible as and when it is needed. Some causes for unavailability my include unintentional hardware failures and also malicious activities that deny authorized users access. Confidentiality means that only the intended recipient will have access to the data and removes the risk of misuse when the information falls in the wrong hands. Most organisations ensure confidentiality through access control and the use of passwords to protect information.
