20、tion The Critical Security Controls (“the Controls“) exist within a larger cyber security ecosystem that relies on the Controls as critically important defensive measures. There are a variety of facilitation mechanisms that facilitate and encourage their use. This document provides a placeholder for

21、 such mechanisms, and initially includes four of them: Privacy Impact Assessment, Mapping to Well-Known Cyber Security Frameworks, Cyber Hygiene Programs, Management Governance.

35、hould not compromise individual privacy. Many laws, regulations, guidelines, and recommendations exist to safeguard privacy, and enterprises will, in many cases, adapt their existing policies on privacy as they apply the Controls. ETSI ETSI TR 103 305-4 V1.1.1 (2016-08)7 At a minimum, use of the Con

36、trols should conform to the general principles embodied in the Fair Information Practice principles (FIPs) i.3 and in Privacy by Design i.4. All enterprises that apply the Controls should undertake - and make available to stakeholders - privacy impact assessments of relevant systems to ensure that a

37、ppropriate protections are in place as the Controls are implemented. Every enterprise should also regularly review these assessments as material changes to its cybersecurity posture are adopted. The aim is to assess and mitigate the major potential privacy risks associated with implementing specific

38、 Controls as well as evaluate the overall impact of the Controls on individual privacy. To assist enterprises in efforts to conduct a privacy impact assessment when implementing the Controls and to contribute to the establishment of a more general reference standard for privacy and the Controls, the

39、 CIS convenes technical and privacy experts to review each Control and offer recommendations for best practice. The following framework guides this efforts and provides an outline for a Privacy Impact Assessment. 4.1 Privacy Impact Assessment of the Critical Security Controls 4.1.1 Overview Outline

40、the purpose of each Control and provide justification for any actual or potential intersection with privacy-sensitive information: Where possible, identify how technologies, procedures, and data flows are used to implement the Control. Provide a brief description of how the Control generally collect

41、s and stores information. Identify the type of data collected by the Control and the kinds of information that can be derived from this data. In discussing how the Control might collect and use PII, include a typical transaction that details the life cycle of that PII from collection to disposal. De

42、scribe the measures necessary to protect privacy data and mitigate any risks of unauthorized access or inadvertent disclosure of the data. The aim here is not to list every possible risk to privacy, but rather, to provide a holistic view of the risks to privacy that could arise from implementation o

43、f the Control. Describe any potential ad-hoc or routine information sharing that will result from the implementation of the Control both within the enterprise and with external sharing partners. Also describe how such external sharing is compatible with the original collection of the information, an

44、d what agreements would need to be in place to support this sharing. 4.1.2 Authorities Identify the legal authorities or enterprise policies that would permit or, conversely, limit or prohibit the collection or use of information by the Control: List the statutory and regulatory authorities that wou

45、ld govern operation of the Control, including the authorities to collect the information identified above. Explain how the statutory and regulatory authorities permit or would limit collection and use of the information or govern geographic storage requirements. If the Control would conceivably coll

46、ect Personally Identifiable Information (PII), also identify the specific statutory authority that would permit such collection. Would the responsible office of an enterprise be able to rely on authorities of another parent organization, subsidiary, partner or agency? Might the information collected

47、 by the Control be received from a foreign user, organization or government? If so, do any international agreement, contract, privacy policy or memorandum of understanding exist to support or otherwise govern this collection? ETSI ETSI TR 103 305-4 V1.1.1 (2016-08)8 4.1.3 Characterizing Control-Rela

48、ted Information Identify the type of data the Control collects, uses, disseminates, or maintains: For each Control, identify both the categories of technology sources, logs, or individuals from whom information would be collected, and, for each category, list any potential PII, that might be gathere

49、d, used, or stored to support the Control: - Relevant information here includes (but is not limited to): name; date of birth; mailing address; telephone numbers; social security number; e-mail address; mothers maiden name; medical records locators; bank account numbers; health plan beneficiaries; any other account numbers; certificates or other license numbers; vehicle identifiers, including license plates; marriage records; civil or criminal history information; medical records; device identifiers and serial numbers; education reco
