National bodies t

15、hat are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other inter

16、national organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its

17、 further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted.

22、ir information at the application level. A systematic approach towards increasing the level of application security provides an organization with evidence that information being used or stored by its applications is being adequately protected. ISO/IEC 27034 (all parts) provides concepts, principles,

23、 frameworks, components and processes to assist organizations in integrating security seamlessly throughout the life cycle of their applications. The application security control (ASC) is one of the key components of this document. To facilitate the implementation of ISO/IEC 27034 (all parts) applic

24、ation security framework and the communication and exchange of ASCs, a formal structure should be defined for representing ASCs and certain other components of the framework. 0.2 Purpose The purpose of this document is to provide examples of security guidance for organizations to acquire, develop, o

25、utsource and manage security for their specific applications through their life cycle. 0.3 Targeted Audiences 0.3.1 General The following audiences will find values and benefits when carrying their designated organizational roles: a) domain experts. 0.3.2 Domain experts Domain experts contributing k

26、nowledge in application provisioning, operating or auditing, who need to a) participate in ASC development, validation and verification, b) participate in ASC implementation and maintenance, by proposing strategies, components and implementation processes for adapting ASCs to the organizations conte

27、xt, and c) validate that ASCs are useable and useful in application projects.

31、panies trying to implement any best practice or ISO standard because they instruct how to institutionalize the practices or rules and, sometimes, the guidance is based on common examples. Companies benefit from this guidance as it demonstrates, as a practical example, how to structure ASCs for speci

32、fic applications using the recommended XML data structure defined in ISO/IEC 27034-5-1 and for the implementation of the Organizational Normative Framework.

33、le: Java code revision for mobile applications 5.2.1 General Code review seams trivial but when an application is built from thousands of lines of code, it may be unproductive and/or too expensive to revise everything. This example presents an ASC designed by a fictive organization called ORGANIsati

34、on Inc. This ASC implements the security activity of code review. 5.2.2 Purpose The purpose of 5.2 is to provide an intuitive description of an example ASC named “Code Review” for an organization developing Java mobile applications. For the sake of brevity and readability, a simplified subset of the

35、 ASC is presented in English only (language=”EN”), but the ASC requirements defined in ISO/IEC 27034-5 allows any object in an ASC to be described in any characters sets, as presented by the Table A.1. 5.2.3 Context ORGANIsation Inc. is an international organization developing Java mobile applicatio

36、ns for its own use and on behalf of its clients. ORGANIsation software development offices are located in Montreal, Vancouver and Moscow. For this reason, ORGANIsations policy is that any development documentation, guideline or training should be available in English, French and Russian languages. O

37、RGANIsations implementation strategy for ISO/IEC 27034 (all parts) prioritizes the design of ASCs for reducing security vulnerabilities in Java mobile code. The ORGANIsation ONF committee mandates the Application Security Department (ASD) to design and submit Java code review ASCs. 5.2.4 OR G ANIsat

38、ion Information classification gu idelines ORGANIsation utilizes approved internal classification guidelines for classifying the information into four levels: a) restricted; b) confidential; c) secret; d) top secret. 5.2.5 Levels of trust included in the ORGANIsation ASC Library ORGANIsation had pre

39、viously conducted an organization-wide security risk assessment, for the purpose of which it divided its applications into six categories according to their impact on organizational risk. Following this, domain experts mandated by the ONF committee decided to use those six categories as a template f

40、or defining ORGANIsations application levels of trust. An informal definition along with a descriptive label for each level of trust is given in Table 1.2 ISO/IEC 2016 All rights reserved BS ISO/IEC 270346:2016 ISO/IEC 27034-6:2016(E) Table 1 ORGANIsations application levels of trust Level of trust

After analysis of vendor propositions, the department selected a tool named “Efficient-Reviewer version 2.2”. At the end of this project, version 1.0
