- ITSEC
In May 1990,
France ,Germany , theNetherlands and theUnited Kingdom published the Information Technology Security Evaluation Criteria (ITSEC) based on existing work in their respective countries. Following extensive international review, Version 1.2 was subsequently published in June 1991 by theCommission of the European Communities for operational use within evaluation and certification schemes.The ITSEC is a structured set of criteria for evaluating computer security within products and systems. The product or system being evaluated, called the "target of evaluation", is subjected to a detailed examination of its security features culminating in comprehensive and informed functional and penetration testing.
The degree of examination depends upon the level of confidence desired in the target. To provide different levels of confidence, the ITSEC defines "evaluation levels", denoted E0 through E6. Higher evaluation levels involve more extensive examination and testing of the target.
Unlike earlier criteria, notably the
TCSEC developed by the US defense establishment, the ITSEC did not require evaluated targets to contain specific technical features in order to achieve a particular assurance level. For example, an ITSEC target might provide authentication or integrity features without providing confidentiality or availability. A given target's security features were documented in a "Security Target" document, whose contents had to be evaluated and approved before the target itself was evaluated. Each ITSEC evaluation was based exclusively on verifying the security features identified in the Security Target.Since the launch of the ITSEC in 1990, a number of other European countries have agreed to recognise the validity of ITSEC evaluations.
The ITSEC has been largely replaced by
Common Criteria , which provides similarly-defined evaluation levels and implements the target of evaluation concept and the Security Target document.External links
