Definition of security
Generic term for all the measures taken to protect against:
•
Loss of confidentiality due to unauthorized access to data
•
Loss of integrity due to manipulation of data
•
Loss of availability due to destruction of data, for example, through faulty configuration
and denial-of-service attacks
Threats
Threats can arise from external and internal manipulation. The loss of data security is not
always caused by intentional actions.
Internal threats can arise due to:
•
Technical errors
•
Operator errors
•
Defective programs
Added to these internal threats there are also external ones. The external threats are not
really any different to the known threats in the office environment:
•
Software viruses and worms
•
Trojans
•
Man-in-the-middle attacks
•
Password Phishing
•
Denial of Service
