[CCCure CISSP] Q15April-13 Some cccure Quiz question doubts

Amlan Deb
Hello everyone,
 
I have some doubts regarding some cccure Quiz questions and concepts mentioned below. Would really appreciate it if you
could take out some time and help me with them. Request you to please provide a quick reply as I need to appear for the
exam in the month of July.
 
Thanks,

1.     Question: 1336 | Difficulty: 5/5 | Relevancy: 3/3

What can best be defined as the detailed examination and testing of the security features of an IT system or product to ensure that they work correctly and effectively and do not show any logical vulnerabilities, such as evaluation criteria?

o      Acceptance testing

o     Evaluation

o      Certification

o      Accreditation

You did not provide any answer to this question. Please review details below.

The correct answer is:  Evaluation

Evaluation as a general term is described as the process of independently assessing a system against a standard of comparison, such as evaluation criteria.  Evaluation criterias are defined as a benchmark, standard, or yardstick against which accomplishment, conformance, performance, and suitability of an individual, hardware, software, product, or plan, as well as of risk-reward ratio is measured.

What is computer security evaluation?

Computer security evaluation is the detailed examination and testing of the security features of an IT system or product to ensure that they work correctly and effectively and do not show any logical vulnerabilities. The Security Target determines the scope of the evaluation. It includes a claimed level of Assurance that determines how rigorous the evaluation is.

Criteria

Criteria are the "standards" against which security evaluation is carried out. They define several degrees of rigour for the testing and the levels of assurance that each confers. They also define the formal requirements needed for a product (or system) to meet each Assurance level.

TCSEC
The US Department of Defense published the first criteria in 1983 as the Trusted Computer Security Evaluation Criteria (TCSEC), more popularly known as the "Orange Book". The current issue is dated 1985. The US Federal Criteria were drafted in the early 1990s as a possible replacement but were never formally adopted.

ITSEC
During the 1980s, the United Kingdom, Germany, France and the Netherlands produced versions of their own national criteria. These were harmonised and published as the Information Technology Security Evaluation Criteria (ITSEC). The current issue, Version 1.2, was published by the European Commission in June 1991. In September 1993, it was followed by the IT Security Evaluation Manual (ITSEM) which specifies the methodology to be followed when carrying out ITSEC evaluations.

Common Criteria
The Common Criteria represents the outcome of international efforts to align and develop the existing European and North American criteria. The Common Criteria project harmonises ITSEC, CTCPEC (Canadian Criteria) and US Federal Criteria (FC) into the Common Criteria for Information Technology Security Evaluation (CC) for use in evaluating products and systems and for stating security requirements in a standardised way. Increasingly it is replacing national and regional criteria with a worldwide set accepted by the International Standards Organisation (ISO15408).

The following answer were not applicable:

Certification is the process of performing a comprehensive analysis of the security features and safeguards of a system to establish the extent to which the security requirements are satisfied.  Shon Harris states in her book that Certification is the comprehensive technical evaluation of the security components and their compliance for the purpose of accreditation.

Wikipedia describes it as:  Certification is a comprehensive evaluation of the technical and non-technical security controls (safeguards) of an information system to support the accreditation process that establishes the extent to which a particular design and implementation meets a set of specified security requirements

Accreditation is the official management decision to operate a system.  Accreditation is the formal declaration by a senior agency official (Designated Accrediting Authority (DAA) or Principal Accrediting Authority (PAA)) that an information system is approved to operate at an acceptable level of risk, based on the implementation of an approved set of technical, managerial, and procedural security controls (safeguards).

Acceptance testing refers to user testing of a system before accepting delivery.

My doubt:   I often get confused differentiating Evaluation, Certification, Testing, Verification, Validation. Are there any tips to differentiate them?
