Data privacy vs. data protection

Data privacy focuses on individual rights and preferences about how personal information should be collected and used. Data protection involves the actual methods and policies organizations implement to meet those privacy expectations. Simply put, data privacy is the demand for protection, while data protection is how that demand gets fulfilled.

Data protection vs. data security

Data security focuses on the technical tools and practices that prevent unauthorized access, breaches, and cyberattacks. Data protection focuses more on the policies, procedures and legal frameworks organizations use to guide data management and ensure personal information is handled responsibly. In short, data protection is about compliance and proper handling, while data security is about defending against threats and securing systems.

What is data protection?

Data protection is the process of preventing sensitive information from corruption and loss. It aims to keep data available and within the compliance guidelines set by regulators. When done correctly, data protection can stop unauthorized users from disclosing, changing, or destroying data. Data protection applies to the entire data lifecycle, from when it’s created to when it’s deleted. Within that cycle, data protection keeps the data immutable and accessible for those authorized to access it.

Businesses employ several different data protection technologies, including the following:

• Data backups: This practice creates a system of continuous data protection by ensuring that a secondary copy of the data always exists. Businesses can quickly recover and restore the missing information in case of data loss.

• Encryption: Data encryption protects sensitive data from exposure if it is improperly stored or shared. It is a key part of ensuring a business complies with regulatory requirements.

• Firewalls: Firewalls monitor and control incoming and outgoing network traffic, preventing unauthorized users from gaining access to data they shouldn’t.

What is data protection used for?

Data protection plays a key role in ensuring any data being preserved for use complies with regulatory requirements. Governments set forward legislation that outlines both the types of data businesses have permission to collect and how professionals must protect and store data for future use. Data protection strategies typically involve implementing policies and practices that ensure professionals use data legally and ethically. It details the technical components of how and why data storage and utilization occurs.

Companies use various data protection techniques to keep sensitive customer information out of the wrong hands. Data protection methods include: 

• Encryption: This is a technique whereby sensitive information is “scrambled” into a secret code that another end-user can only unlock if they possess a unique digital key.

• Data masking: This is a way of hiding sensitive information by modifying it with structurally similar data. The original data would then be untrackable. 

• File redaction: This involves removing information from files to help hackers identify customers or their sensitive information. The idea is the same as that of paper redaction of government files. 

• Automated reporting involves installing an always-on cybersecurity framework that constantly scans your business’s data for threats. Theoretically, this allows for faster threat detection and response. 

Advantages of data protection

Data protection provides many advantages to businesses, including the assurance that important data stays available to streamline operations and improve customer experiences. It can also prevent businesses from paying massive fines for not complying with governments’ regulatory requirements. So, if a data breach or hack does happen, data protection measures help reduce downtime and minimize data loss.

Data protection challenges

Meeting data protection requirements can be complex and resource-intensive for organizations. Due to the complicated requirements set forth by governments, such as the General Data Protection Regulation (GDPR), Health Insurance Portability and Accountability Act (HIPAA), and Children's Online Privacy Protection Act (COPPA), it can be expensive and time-consuming to consistently ensure that your data frameworks comply with the newest legislation, which tends to change quite frequently. These aren't optional considerations but necessary investments to avoid legal consequences and maintain consumer trust.

What is data security?

Data security mainly focuses on preserving data integrity. This includes ensuring data stays confidential using systems that prevent breaches or hacks resulting in data theft or destruction. Data security is a subset of data protection, but instead of encompassing the broader issue of data availability, it focuses on who can access data and prevent theft. Data security involves the physical security of items such as storage devices or hardware and the logical security of software and organizational policies and procedures.

What is data security used for?

Data security protects data, networks, and devices from unapproved access, unauthorized users, and cyberattacks or threats. It involves implementing technology, policies, techniques, and procedures that work together to prevent data loss.

Data security uses a wide range of tools, including the following:

• Data erasure: Data erasure allows for overwriting data on any storage device, which is much more secure than the standard deletion of data.

• Access management: Access management ensures that only authorized users can access certain data types.

• Activity monitoring: This process monitors data and file activity to look for suspicious activity, alerting a data security management team to hacking or breach attempts.

Advantages of data security

Data security has many advantages, including keeping a business’s data safe from hackers, maintaining customer trust in your brand since you protect their data, and preventing financial losses from cyberattacks. 

Data security challenges

Implementing effective data security comes with significant operational hurdles. The tools, technologies, and ongoing maintenance required to secure systems can be costly and resource-intensive. Additionally, even the best security measures can be undermined by human error, such as employees clicking malicious links, using weak passwords, or failing to follow security protocols. This means organizations must invest not only in technical solutions but also in continuous training and security awareness programs to minimize these vulnerabilities.

What is data privacy?

Data privacy is the right individuals have to control how their personal information is collected, used, and shared by organizations. This includes highly sensitive data such as contact information, credit card numbers, and biometric data that companies routinely collect during everyday interactions. While businesses rely on user data for research, targeted advertising, and operational purposes, individuals have concerns about how this information might be misused. Poor data handling can lead to identity theft, financial fraud, and other serious harms when cybercriminals gain access to inadequately protected personal information.

What is data privacy used for?

Data privacy is used to establish individual rights and expectations around personal information. People use data privacy principles to set boundaries on what information they're willing to share, with whom, and under what circumstances. It gives individuals control over their digital footprint and allows them to make informed decisions about consent when companies request access to their personal data. Data privacy also serves as the foundation for building trust between individuals and organizations, ensuring that people can participate in the digital economy without surrendering all control over their personal information. Essentially, data privacy empowers individuals to maintain autonomy over their most sensitive details in an increasingly connected world.

Advantages of data privacy

Data privacy benefits both individuals and organizations in significant ways. For individuals, strong privacy protections provide peace of mind, reduce risk of identity theft and fraud, and give people control over their personal information. Organizations that prioritize data privacy often gain competitive advantages through increased customer trust and loyalty, as people are more willing to share information with companies they trust to handle it responsibly. Additionally, compliance with privacy regulations helps businesses avoid costly fines and legal penalties, while also encouraging innovation in privacy-preserving technologies. Strong data privacy practices also create a healthier digital ecosystem where people feel safer participating online, ultimately benefiting the broader economy and society.

Data privacy challenges

For everyday users, privacy policies are often confusing and difficult to understand, making it hard to make informed choices about sharing personal information. Additionally, balancing privacy with functionality can be tricky, as stronger privacy protections sometimes mean less convenience or personalized services. As new technologies like AI continue to emerge, privacy frameworks need updating to address fresh risks and challenges. Organizations must comply with different regional regulations like GDPR and CCPA, which requires significant resources to implement properly. Managing data across multiple systems while maintaining privacy protections demands technical expertise and ongoing investment.
