Data Privacy Versus Data Security  Organizations commonly believe that keeping sensitive data secure from hackers means they’re automatically compliant with data privacy regulations  Data privacy and data security are often used interchangeably, but there are distinct differences, although sometimes difficult to distinguish between. Whereas security controls can be met without also satisfying privacy considerations, privacy concerns are impossible to address without first employing effective security practices. In other words, security protects data, and privacy protects the identity  Privacy and security come down to which data is being protected, how it’s being protected, from whom it’s being protected, and who is responsible for that protection. Security is about protecting data from malicious threats, whereas privacy is about using data responsibly.  Data privacy is a part of the data protection area that deals with the proper handling of data, with the focus on compliance with data protection regulations.  Data privacy focuses on the rights of individuals, the purpose of Figure 1.

It focuses on how to collect, process, share, archive, and delete the data under the law. 01 Handout 1 *Property of STI  [email protected] Page 1 of 3  IT2028  CIA Triad is a model designed to guide an organization’s Aspect of Privacy policies on information security.

Most websites publish a privacy policy that details the website's intended use of collected online and/or offline collected data. o Financial privacy: Financial information is particularly sensitive, as it may easily use to commit online and/or offline fraud. o Medical privacy: All medical records are subject to stringent laws that address user access privileges.

Privacy by Design Principles Privacy by Design  A useful guide to developing a PbD approach is the set of  In dealing with the privacy of PII, two (2) new concepts have foundational principles for PbD first proposed by Ann Cavoukian, emerged: privacy by design (PbD) and privacy engineering. as shown in Figure 2. These principles were later widely adopted  The goal of privacy by design is to take privacy requirements into as a resolution by other prominent policymakers at the 32nd account throughout the system development process, from the Annual International Conference of Data Protection and Privacy conception of a new IT system through detailed system design, Commissioners meeting. implementation, and operation. o Privacy requirements: These are system requirements that have privacy relevance. System privacy requirements define the protection capabilities provided by the system, the performance and behavioral characteristics exhibited by the system, and the evidence used to determine that the system privacy requirements have been satisfied. Privacy requirements are derived from various sources, including laws, regulations, standards, and stakeholder expectations.  Figure 1 provides an overview of the major activities and tasks involved in integrating information privacy protection into any information system developed by an organization. The upper part of the figure encompasses design activities that determine what is needed and how to satisfy requirements. The lower part of the figure deals with the implementation and operation of privacy features as part of the overall system. Figure 2.
