What is Privacy Engineering in Cybersecurity?

Privacy engineering, which focuses on building privacy into technology from the beginning, is becoming very important for protecting personal information and obeying privacy laws. There’s a lot more demand for people who know how to do this—about 67% more in the last decade. This means that people understand that it’s better to plan for privacy early in the creation of new tech. In this article, we are going to discuss privacy engineering.

What is Privacy Engineering?

Privacy Engineering ensures that privacy is considered in developing and managing IT systems at every stage. It utilizes various methods, tools, and procedures to implement Privacy by Design (PbD) effectively. PbD focuses on integrating privacy protections into systems from the beginning. The increased reliance on digital technology during the pandemic highlights the importance of PbD. The ultimate aim of privacy engineering is to establish PbD as the standard approach for constructing IT systems.

Meaning of Privacy Engineering

Privacy engineering is all about making sure that privacy is part of how technology and products are made. Privacy engineers are the ones who work this into the design process. Different people might have other ideas about what privacy engineering includes like it being a special set of skills or about managing the process. But both ideas are right and play a role. Privacy engineers have jobs in many different areas, like making products, designing, managing information technology, ensuring security, and even in legal and compliance departments. Experts believe that the field needs people who have technology and can combine ideas from making products, developing software, cybersecurity, how people interact with computers, and business and legal stuff. No matter where privacy engineers work, they have to talk to all these different teams and make sure that the products meet privacy rules and standards in a technical sense.

Importance of Privacy Engineering in Cybersecurity

1. Legal Requirements

• Privacy laws mandate privacy engineering practices to ensure compliance and protection of individuals’ rights.
• The EU General Data Protection Regulation (GDPR) emphasizes “Privacy by design and by default,” necessitating companies to integrate privacy into their systems and processes.
• The California Consumer Privacy Act (CCPA) calls for a deeper understanding of vendors’ handling of personal information and necessitates technical knowledge to classify service providers versus third parties.

2. Regulatory Enforcement

• Regulators, like the U.S. Federal Trade Commission (FTC), are increasingly enforcing privacy regulations, as demonstrated by the $5 billion settlement with Facebook.
• Regulatory bodies worldwide are investing in understanding privacy engineering to enhance their regulatory measures, such as through regulatory sandboxes and dedicated technology units.

3. Automation Needs

• Automation is becoming crucial for privacy compliance, particularly in light of the GDPR and CCPA requirements.
• Privacy experts predict 2019 to be the year of automation, highlighting the inadequacy of manual methods and the necessity of automation tools for tasks like access requests, data mapping, and incident response.
• As more than 200 privacy tech companies emerge, businesses must invest wisely in automation tools that align with their privacy laws, business processes, and technological needs.

Implementation Steps of Privacy Engineering

• Assess Privacy Risks: Perform a complete privacy risk assessment to discover potential privacy threats and weaknesses in your organization’s data processing activities. This could involve analyzing data flows, data collection techniques, data storage and processing technologies, and third-party data sharing agreements.
• Develop Privacy Policies and Procedures: Create and execute clear and comprehensive privacy policies and processes that agree with all applicable laws, regulations, and industry standards.
• Implement Privacy By Design: Integrate privacy principles and measures into the design and development of technological systems, processes, and activities from the beginning.
• Provide Privacy Training and Awareness: Inform employees and stakeholders about privacy best practices, data protection principles, and their roles and responsibilities in protecting personal information.

Role of Privacy Engineers 

Privacy engineers work to create ways to keep personal information safe and reduce the chances of mistakes by people, without making the technology harder to use or causing problems for businesses. They have to think about laws, being responsible, and new things happening like using multiple cloud services, people working from home, and businesses growing quickly. Since most data leaks happen because of errors, privacy engineering mainly focuses on the tech side but also a little bit on social issues like teaching staff. It’s also helpful for figuring out the best ways to train employees and spot risks that come from human behavior.

Benefits of Privacy Engineering in Cybersecurity

• Less reliance on third-party security enforcement.
• Privacy is a default feature, providing preventative protection.
• Offers complete security across the system’s entire lifecycle.
• Protects user privacy by design.
• Helps companies gain customer trust and avoid future penalties.

Limitations of Privacy Engineering in Cybersecurity

• Requires legislation and policies, many of which are still being made.
• Possible violations from design errors, bad actors, or new technology.
• Implementation can be expensive due to the need for expert engineers

Privacy Engineering vs Privacy-by-Design

• Focus: Privacy engineering focus on the technical aspects of ensuring privacy within systems. It involves implementing technical measures and mechanisms to protect users’ privacy, such as encryption, access controls, data minimization, and anonymization techniques. While Privacy-by-Design is a broader concept that focus not only technical aspects but also organizational, legal, and user-centric considerations. It emphasizes embedding privacy principles and practices into the entire design and development process.
• Process: Privacy engineering involves methodologies and practices to systematically identify, assess, and mitigate privacy risks throughout the lifecycle of a product or system. This may include privacy impact assessments, threat modeling, and privacy-enhancing technologies (PETs). While Privacy-by-Design is guided by principles such as proactive rather than reactive measures, privacy as the default setting, end-to-end security, user-centric design, transparency, and respect for user privacy.
• Goal: The primary goal of privacy engineering is to develop systems that provide strong privacy protections while still delivering the intended functionality and user experience. While the primary goal of Privacy-by-design is embed privacy into the entire design and development.

Globally recognized privacy engineering standards

• General Data Protection Regulation (GDPR): The General Data Protection Regulation (GDPR) is a law made by the European Union (EU) that governs how personally identifiable information is collected, processed, and eventually deleted from a computer system. 
• ISO/IEC 27001: The ISO/IEC 27001 standard is a globally recognized certifications developed by the International Organization for Standardization. It is a standard for validating a cybersecurity program. It is used internationally.
• NIST Privacy Framework: Established in response to the order of Obama, the former president of The United States, the NIST framework is a pathway between public and private sectors to collaborate and work together in order to fight against cyber risks.
• Privacy by Design (PbD): Privacy-by-Design is a broader concept that focus not only technical aspects but also organizational, legal, and user-centric considerations. It emphasizes embedding privacy principles and practices into the entire design and development process.

Conclusion 

Privacy engineering is always evolving, just like the concept of privacy. It’s a key way to protect privacy by making sure it’s included right from the start when new technologies and systems are being made. When companies put privacy protections in from the beginning, they can keep personal data safer and follow the law more easily. Doing this also helps gain users’ trust and reduces the chance of data being stolen or privacy rules being broken.
