Confidentiality In information security, confidentiality "is the property, that information is not made available or disclosed to unauthorized individuals, entities, or processes" Integrity In information security, data integrity means maintaining and assuring the accuracy and completeness of data over its entire life-cycle. This means that data cannot be modified in an unauthorized or undetected manner. This can be also used to validate databases to make sure none of the data is cor...

Confidentiality Information is not made available or disclosed to unauthorized individuals, entities, or processes. Ensures unauthorized persons are not able to read private and sensitive data. It is achieved through cryptography. Integrity Ensures unauthorized persons or channels are not able to modify the data. It is accomplished through the use of a message digest or digital signatures. Availability The computing systems used to store and process information, the security con...
