The most important protection goals of information security are Confidentiality, integrity and availability of information. Data is considered confidential if only authorised persons have access to this information. It must be possible to identify all persons who access the data. This protection goal can be achieved, for example, by means of 2-fold authentication, passwords or encryption. The integrity of data describes that data is kept in its correct and complete state and that it is protected against intended/accidental changes. This includes that unauthorised persons, such as hackers, have no access and thus no possibility to change the data. Availability of information means the guarantee of access to the information in an assured manner for users with the appropriate authorisation.
