1.2 Security
Security refers to the protection of hardware, software, machines and networks from unauthorized access.
Security measures include restricted access to machines and networks for certain employees or to prevent
access by hackers. The degree of security of information systems largely determines society’s confidence in
the information contained in the systems.
1.5 Authenticity
Authenticity means establishing a user’s identity beyond reasonable doubt. Authenticating the user is
crucial in many scenarios, particularly in business and legal matters. A simple example of authentication is
a user login to a network. A more advanced example would be the use of encrypted digital signatures in a
business transaction or the use of watermarking on digital photographs.Network administration
