ISO/IEC – Evaluation Criteria for Information Technology Security represents the The acceptance by ISO will ensure that CC rapidly becomes the world. ISO/IEC establishes the general concepts and principles of IT security evaluation and specifies the general model of evaluation given by various. COMMON CRITERIA ISO/IEC SECURITY 2. The term Common Criteria ( or CC) refers to the “Common Criteria for Information Technology Security.

Evaluations at EAL5 and above tend to involve the security requirements of the host nation's government. In September , a majority of members of the CCRA produced a vision statement whereby mutual recognition of CC evaluated products will be lowered to EAL 2 Including augmentation with flaw remediation. Further, this vision indicates a move away from assurance levels altogether and evaluations will be confined to conformance with Protection Profiles that have no stated assurance level.

This will be achieved through technical working groups developing worldwide PPs, and as yet a transition period has not been fully determined. The emergence of international Technical Communities iTC , groups of technical experts charged with the creation of cPPs.

A transition plan from the previous CCRA, including recognition of certificates issued under the previous version of the Arrangement. Requirements[ edit ] Common Criteria is very generic; it does not directly provide a list of product security requirements or features for specific classes of products: this follows the approach taken by ITSEC , but has been a source of debate to those used to the more prescriptive approach of other earlier standards such as TCSEC and FIPS Value of certification[ edit ] Common Criteria certification cannot guarantee security, but it can ensure that claims about the security attributes of the evaluated product were independently verified.

In other words, products evaluated against a Common Criteria standard exhibit a clear chain of evidence that the process of specification, implementation, and evaluation has been conducted in a rigorous and standard manner. Various Microsoft Windows versions, including Windows Server and Windows XP , have been certified , but security patches to address security vulnerabilities are still getting published by Microsoft for these Windows systems.

This is possible because the process of obtaining a Common Criteria certification allows a vendor to restrict the analysis to certain security features and to make certain assumptions about the operating environment and the strength of threats faced by the product in that environment.

Additionally, the CC recognizes a need to limit the scope of evaluation in order to provide cost-effective and useful security certifications, such that evaluated products are examined to a level of detail specified by the assurance level or PP.

Of course, the TOE is intended to be a specific system or collection of components that can be evaluated. Finally, the evaluated and accepted system should support consistency of the outputs of the previous three rows.

From the point of view of a model, this provides a series of representations that can be checked and compared to one another. This sort of example of consistency suggests broad application of the Common Criteria, particularly to critical infrastructure systems.

Specific requirements were derived from and linked to the CC components. A set of eight example requirements is provided [ Abrams 00 ]. This is followed by a discussion of system integration and acceptance test considerations that result from application of the CC. As a result of several reviews, by a wide spectrum of FAA staff members, the NIMS protection profile was broadly accepted by the community it served.

Recent studies [Keblawi 06] suggest that a more unified approach to security requirements engineering is needed if use of the Common Criteria and its system-level protection profiles SLPPs is to be successful. FTI provides integrated voice, data, and video telecommunications services in the continental U. FTI requirements are expressed in terms of service classes and service interfaces. In this particular case, the vendor is required to demonstrate EAL3.

The authors discuss the meaning of an EAL in the context of a services contract, and also the effort involved in maintaining an EAL during the entire systems life cycle, after systems development. Both the Common Criteria and process assessments were used to maintain a balanced security assurance program. Another example, the PalME project, an electronic purse application for Palm handhelds, provides a case study for application of the Common Criteria [ Vetterling 02 ].

It was felt that there was some documentation overhead associated with use of the CC, but nevertheless using the CC for this project was practical. Recent experience [Barnes 06] indicates that achievement of higher EAL levels is feasible and cost-effective.

In other words, products evaluated against a Common Criteria standard exhibit a clear chain of evidence that the process of specification, implementation, and evaluation has been conducted in a rigorous and standard manner. Various Microsoft Windows versions, including Windows Server and Windows XP , have been certified , but security patches to address security vulnerabilities are still getting published by Microsoft for these Windows systems.

This is possible because the process of obtaining a Common Criteria certification allows a vendor to restrict the analysis to certain security features and to make certain assumptions about the operating environment and the strength of threats faced by the product in that environment.

Additionally, the CC recognizes a need to limit the scope of evaluation in order to provide cost-effective and useful security certifications, such that evaluated products are examined to a level of detail specified by the assurance level or PP. Evaluations activities are therefore only performed to a certain depth, use of time, and resources and offer reasonable assurance for the intended environment.

The TOE is applicable to networked or distributed environments only if the entire network operates under the same constraints and resides within a single management domain.

There are no security requirements that address the need to trust external systems or the communications links to such systems. Based on this and other assumptions, which may not be realistic for the common use of general-purpose operating systems, the claimed security functions of the Windows products are evaluated. Thus they should only be considered secure in the assumed, specified circumstances, also known as the evaluated configuration.

Whether you run Microsoft Windows in the precise evaluated configuration or not, you should apply Microsoft's security patches for the vulnerabilities in Windows as they continue to appear. If any of these security vulnerabilities are exploitable in the product's evaluated configuration, the product's Common Criteria certification should be voluntarily withdrawn by the vendor.

Alternatively, the vendor should re-evaluate the product to include the application of patches to fix the security vulnerabilities within the evaluated configuration.

Failure by the vendor to take either of these steps would result in involuntary withdrawal of the product's certification by the certification body of the country in which the product was evaluated. This shows both the limitation and strength of an evaluated configuration. Objections outlined in the article include:.

Common Criteria

Wheeler suggested that the Common Criteria process discriminates against free and open-source software FOSS -centric organizations and development models. In contrast, much FOSS software is produced using modern agile paradigms.

Although some have argued that both paradigms do not align well, [6] others have attempted to reconcile both paradigms. The UK has also produced a number of alternative schemes when the timescales, costs and overheads of mutual recognition have been found to be impeding the operation of the market:.Such consistency would presumably result in more consistency in applying the Common Criteria to various TOEs.

Based on revised and , British Standard Part 2. This grouping allows specific classes of requirements to be evaluated in a standard way in order to arrive at an Evaluation Assurance Level. Part 3 catalogues the set of assurance components, families and classes.

This provides benefits when implementing a family of related products or a product line.
