National bodies that are members of ISO or IEC participate in the

12、 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 international organizations, governmental and non-gov

13、ernmental, 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task

14、 of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a v

The audience for this

17、standard includes consumers, developers, vendors, and evaluators of secure IT products. The following audiences may use this standard: developers and vendors, when responding to reported actual or potential vulnerabilities; evaluators, when assessing the security assurance afforded by vendors and de

18、velopers vulnerability handling processes and the associated products and services; consumers, when selecting product and online service vendors to express best practice assurance requirements to developers, vendors and integrators. This International Standard is related to ISO/IEC 29147. 5It interf

19、aces with elements described in ISO/IEC 29147 at the point of receiving potential vulnerability reports, and at the point of distributing vulnerability resolution information. This International Standard takes into consideration the relevant elements of ISO/IEC 15408-3, 113.5 Flaw remediation (ALC_F

32、IEC 29147 5- Vulnerability disclosure and ISO/IEC 30111 - Vulnerability handling processes are related standards, as Figure 1 shows. ISO/IEC 29147 provides a guideline for vendors to include in their normal business processes on receiving information about potential vulnerabilities from people or or

33、ganizations externally and distributing vulnerability resolution information to affected users. ISO/IEC 30111 gives guidelines for how to process and resolve potential vulnerability information reported by individuals or organizations that find a potential vulnerability in a product or online servic

34、e. While ISO/IEC 29147 deals with the interface between vendors and those who find and report potential vulnerabilities, ISO/IEC 30111 deals with the investigation, triage, and resolution of vulnerabilities, regardless if the source of the potential vulnerability was external to the vendor, or from

35、within the vendors own organization, typically security, development, or testing teams.2 ISO/IEC 2013 All rights reservedBS ISO/IEC 30111:2013ISO/IEC 30111:2013(E) Figure 1 A model of the Interface between ISO/IEC 29147 and ISO/IEC 30111 6 Policy and Organizational Framework for Vulnerability Handli

36、ng Processes 6.1 General Vendors should create a vulnerability handling process in accordance with this International Standard in order to prepare for investigating and resolving potential vulnerabilities. The creation of a vulnerability handling process is a task that is performed by a vendor, and

37、should be periodically assessed to facilitate process improvement opportunities and ensure that the process performs as expected. Vendors should document their vulnerability handling procedure in order to ensure that it is repeatable. The documentation should describe the procedures and methods used

38、 to track all reported vulnerabilities. ISO/IEC 2013 All rights reserved 3BS ISO/IEC 30111:2013ISO/IEC 30111:2013(E) See ISO/IEC 27034 3for information on how identification of the root cause of a vulnerability, which is a step in the process of vulnerability handling, can help improve secure softwa

39、re development lifecycles and result in an outcome of more secure product development. The following clause describes the elements that vendors should consider included in their vulnerability handling processes. 6.2 Vulnerability Handling Policy Development A vendor should develop and maintain a vul

40、nerability handling policy to define and clarify its intentions when investigating and remediating vulnerabilities for the development of a vulnerability handling process. The policy should consist of two parts: an internal-only portion and a public portion. The internal-only part of the policy is i

41、ntended for the vendors staff and defines who is responsible in each stage of the vulnerability handling process and how they should handle information on potential vulnerabilities. It should include the following items: a) basic guidance, principles, and responsibilities for handling potential vuln

42、erabilities in products or online services; b) a list of departments and roles responsible for handling potential vulnerabilities; c) safeguards to prevent premature disclosure of information about potential vulnerabilities before they are fixed. The audience for the public part of the vulnerability

43、 handling policy is internal and external stakeholders, including finders who wish to report potential vulnerabilities, and users of the vendors products or online services. It informs the audience of how the vendor is willing to interact with them when a potential vulnerability is found in the vend

44、ors product or online services. Guidance, details and examples of public vulnerability handling policies are described in the sections describing vulnerability disclosure processes in ISO/IEC 29147. 5 6.3 Development of an Organizational Framework to Support the Vulnerability Han- dling Process 6.3.

45、1 General Handling vulnerabilities has several additional aspects than just engineering and technology (for example, customer service and public relations). An organizational framework should be designed, recognized, and supported by the stakeholder divisions of the vendor responsible for each area.

46、 An organization should have a role or capability that is responsible for and has authority to make decisions on vulnerability handling, preferably at a management level. This role or capability must understand the responsibility toward the vendors users, the internal processes, and the organization

47、al framework for vulnerability handling. An organization should have a role or capability that is a point of contact for handling potential vulnerabilities. This point of contact should be identified for each division or department within a vendor that provides products or online services to custome

48、rs. An organization should establish a point of contact for external parties to reach and communicate with about vulnerabilities. The point of contact may be part of a vendor computer security incident response team (vendor CSIRT) or a product security incident response team (PSIRT). Its details are

49、 discussed in 6.4. Since customers and members of the media may contact the vendor with questions or requests for additional information after a vulnerability is disclosed, divisions responsible for customer and public relations should be prepared so that they can respond.4 ISO/IEC 2013 All rights reservedBS ISO/IEC 30111:2013ISO/IEC 30111:2013(E) 6.4 Vendor CSIRT or PSIRT 6.4.1 General A vendor CSIRT or PSIRT is responsible for coordinating vulnerability reports from external finders of vulnerabilit
