The metrics associated with privacy data breaches are astounding. In 2016, 554,454,942 records were breached from 974 reported incidents.1 To break down the type of data affected, 48 percent of data breach incidents were for personally identifiable information (PII), 27 percent were for credit and debit card data, and 11 percent were for physical health information (PHI).2

The root causes of privacy incidents include the outsourcing of data, malicious insiders, system glitches, cyberattacks, and the failure to shred or dispose of privacy data properly. The human element of data breaches is the result of social engineering, financial pretexting (the practice of obtaining personal information under false pretenses), digital extortion, insider threat and partner misuse.3 Conduit devices used include Universal Serial Bus (USB) infection, rogue network connections, manipulation of account balances and backdoor access accounts. Configuration exploitation and malicious software are also causes of data compromises.

This article will review many aspects of privacy and is intended as a primer for information privacy. Topics to be reviewed are categories of privacy, privacy officer (PO) concerns, governance strategy, privacy controls and the privacy plan.

Categories of Privacy

ISACA has identified seven categories of privacy that every enterprise must address, as shown in figure 1.4

Figure 1

Privacy Information Concerns

To address the personal and organizational concerns of data privacy, the position of PO was created. Figure 25 shows data concerns, areas of risk and questions the PO must ask.

All of these concerns help to identify the scope and complexity of the work. Data governance methods and techniques that need to be employed include data identification, protective measures, intrusion detection monitoring and reporting, responding to privacy events and incidents, and recovery of the organization to normalcy (when possible).

Governance Activities

Governance of privacy-related information requires that a custom strategy be developed for any organization. Governance activities should include:

  • Identifying the stakeholders and internal partnerships.
  • Developing vision, mission and value statements with goals and objectives. This information would be a reference and resource for a privacy charter that can be used throughout the course of the privacy policy development effort.
  • Establishing connections within the organization to ensure cooperation and efficiency.
  • Writing a privacy policy (described in a following section) to address warning banners; system compromise alerts; key persons to contact; and response, containment, and recovery processes and procedures.
  • Developing a data governance strategy that includes data collection, authorized use, access controls, information security and destruction of the data/information. The key functional aspects are assessment, protection, sustaining privacy operations and responding to compromises.
  • Establishing a privacy budget that includes outreach activities and a contingency reserve for recovery and emergency expenditures. The expenditures would include forensic investigations, victim notification, call center support, outside counsel (e.g., litigation costs), security enhancements, lost revenue and stock value, insurance, remediation actions, punitive costs (e.g., civil penalties and fines), customer retention, card replacement, victim damages, and opportunity costs.
  • Performing impact assessments/audits. A privacy impact assessment (PIA) questionnaire should be used to inform the PO of possible concerns and potential problems when a computer system is developed or changed. The PIA should identify the types of data, the scope of people affected, the type of information, any new information obtained and the other concerns described previously.
    Privacy audits can measure effectiveness, demonstrate compliance, increase awareness, reveal gaps, and provide a basis for remediation and improvement plans. PIAs can be at all levels, e.g., department, system and process.
  • Establishing a continuous monitoring program. Does the PO receive system monitoring and network access tracking information? Is the PO informed of the results of independent and/or internal systems assessments? Does the assessment cover all of the necessary privacy controls (which are mentioned in the following section)? Have all remedial actions been performed to limit the possibility of a privacy incident? Noncompliance reports should answer the questions what, where, when, why, who and how.
  • Instituting metrics. Metrics should be specific/simple, manageable, actionable, relevant/results-oriented and timely (SMART). Examples of privacy metrics include number of privacy data systems, percentage of data lost, number of privacy incidents, number of systems affected, average time between incidents and average time to recover. Privacy events may not always be large or computer-oriented in nature, but might occur on a small scale, e.g., identity theft.
  • Implementing a privacy incident response plan (PIRP). To quickly respond to data breaches, the PO must be informed of all breaches and have information about the data and systems compromised. The breach plan should include a questionnaire/form, roles and responsibilities, points of contact information (e.g., security, management, legal, public relations, governing organizations), and communication procedures.
  • Providing an information privacy awareness and training program. This could include developing awareness brochures and flyers for internal staff and contractors. All employees, business partners and contractors need to be trained on the privacy policy and procedures.
  • Developing a public privacy website to explain the program and display whom to contact with questions. It could also include frequently asked questions.
  • Ensure that the contingency and disaster recovery plans can recover the data.

Privacy Controls

There are four types of privacy controls: management, computer operations, business operations and technical. Implementing the controls is critical to a successful privacy program. If time permits, they should be implemented in the following order: identify areas of concern, implement protective measures, install detection mechanisms and employ response management techniques.

The four types of privacy controls are described as follows.6

1. Management controls

  • Identification—Responsibilities include documenting legal authority, scrutinizing the new uses of PII, and having an inventory of PII programs and systems.
  • Protective measures—Management must monitor laws for changes; appoint the PO; provide funding; update procedures and tools; explain the privacy program; assign roles and responsibilities; define privacy statements on contracts, acquisition documents and websites; issue privacy notices, policies and procedures; develop a strategic privacy plan; identify and explain why PII is collected; limit the collection and retention of PII; design systems to support privacy (e.g., data minimization); issue data integrity guidance; have external sharing agreements; and appoint a data integrity board and retain PII.
  • Detection—This activity includes conducting PIAs, assessing risk and tracking incidents.
  • Response management—This activity includes reporting incidents to management and governing bodies according to the law.

2. Computer operations controls

  • Identification—Identify systems and files affected.
  • Protective measures—Responsibilities include implementing and maintaining data protection and spillage prevention systems; protect PII in testing, training and research; developing and maintaining a PIRP; and training and monitoring staff.
  • Detection—Operations needs to write incident and activity reports for management.
  • Response management—Responsibilities include training for and providing forensic support; issuing spillage and data breach alerts; and using approved methods to delete or destroy PII as prescribed by management.

3. Business operations controls

  • Identification—Identify what business operations are affected.
  • Protective measures—Measures include approving website content, explaining the consent and information usage program, and obtaining consent of the affected party when applicable.
  • Detection—This activity includes monitoring business practices for fraud, identity theft and data misuse.
  • Response management—This area covers data spillage-handling activities, tracking and retaining records of disclosure, notifying those affected, supplying information to requestors, correcting erroneous PII, explaining individual rights, managing complaints, and responding to privacy spillage incidents.

4. Technical controls

  • Identification—This activity includes reviewing and assessing security tools and determining if other tools need to be acquired and implemented.
  • Protective measures—Measures include account authentication (e.g., account with a password); providing user access cards; using multifactor authentication, automatic time-out and external/remote access controls; data encryption in transit and at rest, network protective devices and software; software updates and patches; data integrity controls; technical control testing; and sanitizing and destroying data in compliance with government regulations.
  • Detection—This category includes the use of data mining software and cyberdetection techniques. It could also include the use of surveillance software in the systems infrastructure and devices in the building, as well as system and application transaction audit controls
  • Response management—Computer forensic analysis techniques and software are needed.

Privacy Plan

A privacy plan must include information for management, data handling operations (e.g., the data center or service provider), business operations and technical controls. The plan content should include the following:

  • List of authorities—This list identifies who is dictating the compliance and reporting requirements and could also include the source of guidance and standards.
  • Definitions—The types of privacy data must be defined to support the information contained in the plan.
  • Scope and purpose—The plan should state who is affected by the plan, a general description of the plan and why it was written.
  • Roles and responsibilities—The roles of various enterprise areas, including the PO, the office of information security, legal department, human resources, public relations, marketing, business development, finance and customer care need to be listed in the privacy plan. It is important for each area to know what needs to be communicated and what needs to be done, in what order and in what time frame. This should be supplemented by training and periodic tabletop exercises.
  • Privacy controls—The plan should describe the requirements of the four categories of controls (previously described) and how the controls are to be implemented.
  • Other considerations—This part of the plan would address areas of the governance strategy not covered and could be oriented to the industry or area of personal concern (e.g., financial, medical). A list of acronyms may also be needed.

Conclusion

The PO must identify the data, understand the business use of the data, protect the data, detect when the data are in jeopardy or have been exposed, and know how and what to do about it. Joining privacy associations, subscribing to privacy-related journals, following best practices from privacy organizations and having a comprehensive privacy plan will help to protect the data and everyone involved.
