The terms data protection and data privacy are often used interchangeably, but there is an important difference between the two. Data privacy defines who has access to data, while data protection provides tools and policies to actually restrict access to the data. Compliance regulations help ensure that user’s privacy requests are carried out by companies, and companies are responsible to take measures to protect private user data. Show
Data protection and privacy is typically applied to personal health information (PHI) and personally identifiable information (PII). It plays a vital role in business operations, development, and finances. By protecting data, companies can prevent data breaches, damage to reputation, and can better meet regulatory requirements. Data protection solutions rely on technologies such as data loss prevention (DLP), storage with built-in data protection, firewalls, encryption, and endpoint protection. In this article:
What Is Data Protection and Why Is It Important?Data protection is a set of strategies and processes you can use to secure the privacy, availability, and integrity of your data. It is sometimes also called data security. A data protection strategy is vital for any organization that collects, handles, or stores sensitive data. A successful strategy can help prevent data loss, theft, or corruption and can help minimize damage caused in the event of a breach or disaster. What Are Data Protection Principles?Data protection principles help protect data and make it available under any circumstances. It covers operational data backup and business continuity/disaster recovery (BCDR) and involves implementing aspects of data management and data availability. Here are key data management aspects relevant to data protection:
Related content: Read our guide to data protection principles What Is Data Privacy and Why Is it Important?Data privacy is a guideline for how data should be collected or handled, based on its sensitivity and importance. Data privacy is typically applied to personal health information (PHI) and personally identifiable information (PII). This includes financial information, medical records, social security or ID numbers, names, birthdates, and contact information. Data privacy concerns apply to all sensitive information that organizations handle, including that of customers, shareholders, and employees. Often, this information plays a vital role in business operations, development, and finances. Data privacy helps ensure that sensitive data is only accessible to approved parties. It prevents criminals from being able to maliciously use data and helps ensure that organizations meet regulatory requirements. What Are Data Protection Regulations?Data protection regulations govern how certain data types are collected, transmitted, and used. Personal data includes various types of information, including names, photos, email addresses, bank account details, IP addresses of personal computers, and biometric data. Data protection and privacy regulations vary between countries, states, and industries. For example, China has created a data privacy law that went into effect on June 1, 2017, and the European Union’s (EU) General Data Protection Regulation (GDPR) went into effect during 2018. Non-compliance may result in reputation damages and monetary fines, depending on the violation as instructed by each law and governing entity. Compliance with one set of regulations does not guarantee compliance with all laws. Additionally, each law contains numerous clauses that may apply to one case but not another, and all regulations are subject to changes. This level of complexity makes it difficult to implement compliance consistently and appropriately. Learn more in our detailed guides to:
Data Protection vs Data PrivacyAlthough both data protection and privacy are important and the two often come together, these terms do not represent the same thing. One addresses policies, the other mechanisms Data privacy is focused on defining who has access to data while data protection focuses on applying those restrictions. Data privacy defines the policies that data protection tools and processes employ. Creating data privacy guidelines does not ensure that unauthorized users don’t have access. Likewise, you can restrict access with data protections while still leaving sensitive data vulnerable. Both are needed to ensure that data remains secure. Users control privacy, companies ensure protection Another important distinction between privacy and protection is who is typically in control. For privacy, users can often control how much of their data is shared and with whom. For protection, it is up to the companies handling data to ensure that it remains private. Compliance regulations reflect this difference and are created to help ensure that users’ privacy requests are enacted by companies. Learn more in our detailed guides to:
12 Data Protection Technologies and Practices to Protect Your DataWhen it comes to protecting your data, there are many storage and management options you can choose from. Solutions can help you restrict access, monitor activity, and respond to threats. Here are some of the most commonly used practices and technologies:
Related content: Read our guide to continuous data protection Critical Best Practices for Ensuring Data PrivacyCreating policies for data privacy can be challenging but it’s not impossible. The following best practices can help you ensure that the policies you create are as effective as possible. Inventory Your DataPart of ensuring data privacy is understanding what data you have, how it is handled, and where it is stored. Your policies should define how this information is collected and acted upon. For example, you need to define how frequently data is scanned for and how it is classified once located. Your privacy policies should clearly outline what protections are needed for your various data privacy levels. Policies should also include processes for auditing protections to ensure that solutions are applied correctly. Related content: Read our guide to data protection impact assessment Minimize Data CollectionEnsure that your policies dictate that only necessary data is collected. If you collect more than what you need, you increase your liability and can create an undue burden on your security teams. Minimizing your data collection can also help you save on bandwidth and storage. One way of achieving this is to use “verify not store” frameworks. These systems use third-party data to verify users and eliminate the need to store or transfer user data to your systems. Be Open with Your UsersMany users are aware of privacy concerns and are likely to appreciate transparency when it comes to how you’re using and storing data. Reflecting this, GDPR has made user consent a key aspect of data use and collection. You can be sure to include users and their consent in your processes by designing privacy concerns into your interfaces. For example, having clear user notifications outlining when data is collected and why. You should also include options for users to modify or opt-out of data collection. Data Protection TrendsHere are some important trends driving the evolution of data protection. Data Portability and Data SovereigntyData portability is an important requirement for many modern IT organizations. It means the ability to move data between different environments and software applications. Very often, data portability means the ability to move data between on-premises data centers and the public cloud, and between different cloud providers. Data portability also has legal implications—when data is stored in different countries, it is subject to different laws and regulations. This is known as data sovereignty. Related content: Read our guide to Data sovereignty Traditionally, data was not portable and it required huge efforts to migrate large datasets to another environment. Cloud data migration was also extremely difficult, in the early days of cloud computing. New technical methods are developing to make migration easier, and thus make data more portable. A related issue is portability of data within clouds. Cloud service providers tend to have proprietary data formats, templates, and storage engines. This makes it difficult to move data from one cloud to another, and creates vendor lock in. Increasingly, organizations are looking for standardized ways of storing and managing data, to make it portable across clouds. Learn more in our detailed guides about:
Mobile Data ProtectionMobile device protection refers to measures designed to protect sensitive information stored on laptops, smartphones, tablets, wearables and other portable devices. A fundamental aspect of mobile device security is preventing unauthorized users from accessing your corporate network. In the modern IT environment, this is a critical aspect of network security. There are many mobile data security tools, designed to protect mobile devices and data by identifying threats, creating backups, and preventing threats on the endpoint from reaching the corporate network. IT staff use mobile data security software to enable secure mobile access to networks and systems. Common capabilities of mobile data security solutions include:
RansomwareRansomware is a rising cybersecurity threat, which is a top security priority for almost all organizations. Ransomware is a type of malware that encrypts user data and demands a ransom in order to release it. New types of ransomware send the data to attackers before encrypting it, allowing the attackers to extort the organization, threatening to make its sensitive information public. Backups are an effective defense against ransomware—if an organization has a recent copy of its data, it can restore it and regain access to the data. However, ransomware can spread across a network over a long period of time, without encrypting files yet. At this stage ransomware can infect any connected system, including backups. When ransomware spreads to backups, it is “game over” for data protection strategies, because it becomes impossible to restore the encrypted data. There are multiple strategies for preventing ransomware and in particular, preventing it from spreading to backups:

Duplicate data creates multiple problems—it increases storage costs, creates inconsistencies and operational issues, and can also result in security and compliance challenges. Typically, not all copies of the data will be secured in the same way. It is no use securing a dataset and ensuring it is compliant, when the data is duplicated in another unknown location. CDM is a type of solution that detects duplicate data and helps manage it, comparing similar data and allowing administrators to delete unused copies. Disaster Recovery as a ServiceDisaster recovery as a service (DRaaS) is a managed service that gives an organization a cloud-based remote disaster recovery site. Traditionally, setting up a secondary data center was extremely complex and involved massive costs, and was only relevant for large enterprises. With DRaaS, any size organization can replicate its local systems to the cloud, and easily restore operations in case of a disaster. DRaaS services leverage public cloud infrastructure, making it possible to store multiple copies of infrastructure and data across multiple geographical locations, to increase resiliency.
