- Data privacy focuses on controlling who has access to personal information, ensuring legal and ethical handling of data, particularly Personally Identifiable Information (PII) and Personal Health Information (PHI)
- Data protection vs. privacy – While both aim to safeguard information, data protection focuses on security measures. In contrast, privacy emphasizes legal and ethical data handling and individual rights.
- Data protection principles include encryption, network, and physical security, ensuring data remains safe, accessible, and unaltered.
Have you ever filled out an online form and wondered who would see your details or where your information would end up in storage?
In the digital economy, data is a precious commodity. For instance, the FTC received over 330,000 reports of business impersonation scams and approximately 160,000 reports of government impersonation scams in 2023. All these scams were possible because user data was compromised.
With social, governmental, and economic activities increasingly taking place online, the flow of personal data is expanding beyond its perceived limits. The dissemination of user data brings up concerns regarding storage, protection, and permitted use, leading to data protection discussions.
This article explores data security and privacy, providing insights into data security and highlighting tips that help safeguard user data in the expanding digital sphere.
What Is Data Security?
Data security is the password on your PC, the biometric authentication on your phone, and the secret handshake in your alma mater. To give data security a proper definition, it is safeguarding digital data from unauthorized access, use, or disclosure in a manner that violates user privacy or an organization’s standings. Protecting user data from destruction, alteration, or disruptions is also integral to data security.
What Are Data Protection Principles?
Data protection principles include broad measures and tools that protect data and make it available without alteration under any circumstance. They involve stakeholders providing data protection guidelines and technologies that actualize these principles.
Below, we highlight five data protection principles.
1. Encryption
To protect data, we must first encode it. Encryption makes this possible. It transforms readable plain text or data into an unreadable form. Even if an unauthorized party accesses the data, encryption obscures the content. Through special keys known as encryption keys, the data remains in the unreadable or encrypted form, known as a cipher text. Only the owner of the special keys can decipher the data back to its readable form.
Among encryption’s benefits is its powerful ability to protect data, even if a cyber attack occurs. When encrypted data falls into the wrong hands, it becomes unreadable gibberish, rendering it useless to the attacker. Furthermore, encryption helps businesses adhere to strict data privacy laws and data compliance like PCI DSS, which protects card transactions.
However, it’s important to remember that encryption isn’t a magic shield. It’s only as strong as its implementation. Should the encryption key be lost or compromised, not even the rightful owner will access the data. It’s also possible to crack encryption algorithms if they are not up to date as cyber threats evolve daily.
2. Backup and Recovery
Data protection and security also means making copies of your information and storing them somewhere secure. If any unfortunate incident occurs to your data, such as loss or corruption, you can readily restore it. Many companies use cloud storage services to keep their data safe and easy to find.
A strategic way to back up your data is to use the 3-2-1 method. It means having three copies of your information on two storage devices, like your computer and an external hard drive, and one copy somewhere else, like in the cloud.
Backing up your data can be a lifesaver in case of a mishap. You can quickly return to your normal state without losing everything. Plus, it can help protect your data from hackers who might try to alter or destroy your data.
Remember to keep your backups safe. Don’t just leave them lying around. Store them somewhere secure, like a different location. And remember to check your backups periodically to make sure they work.
3. Access Control
Data access requires careful management to protect sensitive information. Access control is a mechanism that limits access to authorized individuals. Methods such as passwords, multi-factor authentication, and role-based access control help restrict data to specific groups.
Access control also helps organizations hold people accountable. Tracking individual access and recording their actions makes it possible to identify potential insider threats. Additionally, managing access permissions becomes more efficient, saving time and resources, especially when dealing with many users.
Effective access control requires proper implementation. Strong, unique passwords, coupled with multi-factor authentication, provide robust protection. More recently, blockchain technology is also providing solutions, with token gating a popular way of tailoring data access to individual users.
Whatever solution you’re using, regular system updates and testing are essential to maintaining data security and preventing unauthorized access.
4. Network Security
Data stored on computer networks faces constant threats. Network security safeguards the data from theft, damage, or misuse. Think of it as a shield protecting your information while operating within a network.
Network security involves using several layers of protection.
- Firewalls act like gatekeepers, blocking unwanted visitors.
- Intrusion detection systems watch for suspicious activity, like someone trying to break in.
- Encryption scrambles sensitive information, making network data unreadable to outsiders.
Combining technology and human resources creates the best security. Network security needs skilled IT experts. These systems are complex and require special knowledge to set up and maintain. As threats change, security measures must also adapt. Keeping software updated and training employees about online safety also strengthens network defenses.
5. Physical Security
Preventative physical security safeguards a company’s valuable assets, like servers, networks, and hardware, from threats like theft, damage, and natural disasters. To achieve physical security, you require multiple resources:
- First, people are the foundation of physical security. Security staff watch entry points, regularly patrol the area, and respond to emergencies. Ensure your staff undergo training on identifying potential data security threats.
- Technology adds another layer. Cameras, motion sensors, and alarms deter unwanted visitors and monitor critical areas. Biometrics or cards to unlock doors, combined with secure entry systems, restrict access to sensitive data zones.
- Consider environmental control as well. Fire protection systems, climate regulation to prevent equipment from overheating, and backup power sources like generators keep operations running.
- Establish clear rules for entering buildings, managing visitors, and handling emergencies. Regularly check for weaknesses in physical security and assess risks to help identify potential problems.
While physical security provides peace of mind about data safety and availability, human error remains a significant challenge, as revealed in Thales’ 2023 Data Threat Report. Most data breaches happen because of mistakes, like misplacing or leaving backup media unprotected. Carefully tracking and securing backup storage is vital.
What Is Data Privacy and Why Is it Important?
Data privacy is all about respecting and protecting the information that identifies who you are. It’s like the rulebook for handling, storing, and using personal data such as your name, address, or medical records.
Data privacy often refers to two main types of information: Personally Identifiable Information (PII) and Personal Health Information (PHI).
- PII includes information such as your social security number, email address, or phone number—anything that could identify you.
- PHI covers your health-related details, like the treatments you’ve received or your insurance information.
Why is data privacy so essential?
It ensures individuals have control over their personal information to prevent misuse. Imagine the chaos if someone got hold of your personal details and stole your identity—data privacy helps prevent that.
Data privacy is also essential for business success. Non-compliance with data privacy regulations can result in severe reputational damage and hefty fines. Ultimately, respecting customer privacy builds client trust.
What Are Data Protection Regulations?
Data protection regulations are essential laws that govern how organizations manage and protect personal information. These regulations ensure that individuals’ data remains safe by dictating how organizations collect, store, and process it. The most prominent example is the GDPR by the EU.
The European Union introduced the GDPR in 2018, establishing the most comprehensive data protection laws. Although not flawless, the GDPR imposes detailed data privacy regulations on all businesses serving EU customers. Among the main stipulations of the framework is that businesses must delete your data after a given period. This rule ensures regular people don’t permanently cede their data to companies.
Transparency, consent, and purpose limitation form the core principles of data protection. All data handlers must inform individuals about their data usage and obtain explicit permission before processing it. Additionally, data handling entities should collect and use data solely for legitimate purposes, minimizing unnecessary data collection.
Data Protection vs Data Privacy
Data protection and privacy often get confused, but they’re quite different. It’s like comparing apples and oranges: privacy is about user control, while protection is about company responsibility. Users decide how their data is shared, while companies must safeguard it from harm.
Below are the zones of interaction where companies and users coexist as data stakeholders:
- Area of Focus
- Legal Frameworks
- Data Handling and Management
- User Rights and Control
- Technical Measures
Area of Focus
The main goal of data protection is to protect information from unauthorized access, breaches, and cyber threats. It guarantees data security through methods like encryption and firewalls. By contrast, data privacy refers to the ethical and legal considerations surrounding data collection, utilization, and sharing. It’s more about individual rights and the responsible handling of personal information.
Legal Frameworks
Laws such as the EU’s General Data Protection Regulation (GDPR) typically regulate data protection, requiring specific security measures to prevent data breaches. These frameworks focus on the technical measures that need to be in place.
Conversely, legal standards that define personal data collection, use, and sharing inform data privacy. Laws like the California Consumer Privacy Act (CCPA) ensure that individuals have control over their personal information, emphasizing consent and transparency.
Data Handling and Management
Data protection focuses on implementing security measures such as encryption, firewalls, and access controls to ensure data safety. It’s about maintaining data integrity and confidentiality. Data privacy, however, ensures that data handling respects individuals’ privacy rights.
User Rights and Control
While data protection ensures data safety, it may not grant users complete control over their own information. Under data privacy regulations, users may access, correct, or delete their personal information. This puts the power in the hands of the individuals to decide how their data is used and shared.
Technical Measures
Data protection relies heavily on technical solutions like encryption and multi-factor authentication to shield data from breaches. Data privacy employs technical and organizational measures to ensure that personal data handling follows privacy principles, such as anonymization and data masking.
Data Protection Technologies and Practices to Protect Your Data
Data protection requires companies to adopt a comprehensive approach, incorporating various technologies and practices to safeguard data.
Data Inventory and Classification
Imagine trying to organize your room without first knowing what’s in it. The same goes for data protection. Before securing your data, you need to know what you have.
A data inventory is like a list showing all the data in your organization. It may handle everything from customer contact details to employee records and financial transactions. Knowing what data you have and its storage location is the first step in keeping it safe.
You can find out more about data inventory in the article by Relyanceai.
It is equally crucial to comprehend how data moves within your business operations – data mapping. For instance, knowing how customer data moves from a website form to your internal database helps you identify potential vulnerabilities and protect the data as it moves. Data mapping helps visualize where data originates, its use, and where it ends up.
Data Loss Prevention (DLP)
Now that you’ve identified your data and where it’s going, the next step is to prevent data loss or misuse.
Think of data loss prevention as your data’s bodyguard. It’s a set of tools and policies that prevent unauthorized access, leaks, or the loss of sensitive information. DLP tools constantly monitor your data, looking for signs of trouble. If something suspicious happens, like an employee trying to download a large amount of sensitive data, the DLP system will trigger an alert. The alerts allow you to investigate and take action before any data damage occurs.
When a potential threat is detected, DLP systems can take steps to mitigate the risk. The protection methods may include encrypting the data, restricting access, or blocking the action altogether.
Organizations may also set DLP policies, defining sensitive data so that employees know how to treat such data. They could also train employees on data handling to reinforce the policies put in place. For example, a policy might require that all customer credit card information be encrypted before it’s stored. Employees would then undergo training on the best data encryption methods for credit cards.
Secure Data Storage
Once you’ve inventoried your data and set up DLP measures, ensure your data storage is secure. Part of safeguarding your data storage is preserving multiple copies of your data, a method called redundancy.
Redundancy involves duplicating your data in multiple locations to prevent loss if one storage system fails. For example, if a server crashes, your data will be safe and accessible from a backup location.
Your data must also be free from errors in storage or during data transfer. Error correction techniques identify and fix any errors that may occur because of noise, signal interference, hardware or software issues, or human error.
Finally, secure devices that access your data. Any computer, smartphone, or other hardware devices connected to your network requires protection. Use antivirus software, firewalls, and encryption to guard your data from hackers or malware.
Backup
A backup is a copy of your data stored separately from the original. It acts as a safety measure, safeguarding your data in case the original files are damaged.
There are different types of backups:
- Full Backup: It involves copying all your data every time you back up your data. While it’s the most comprehensive, it requires the most storage space and time.
- Incremental Backup: This only backs up the data that has changed since the last backup. It’s quicker and takes up less space, but can be more complex to restore.
- Differential Backup: It’s like a middle ground, backing up all the data that has changed since the last full backup. It’s faster than a full backup and easier to restore than an incremental one.

Snapshots
While backups are essential, they are only sometimes enough on their own. A snapshot is like a freeze-frame of your data at a specific point in time. It allows you to return to that exact moment if something goes wrong, like spawning from the last save point in a game.
Snapshots offer several advantages:
- Instant Recovery: If you experience data corruption or accidentally delete your data, you can roll back to a previous snapshot, minimizing downtime and data loss.
- Versioning: Snapshots allow you to keep multiple versions of your data. You can track these changes or recover an earlier version of your data through versioning.
- Storage Efficiency: Snapshots only save the changes made since the last snapshot, not the entire dataset, making them faster in data recovery and more storage-efficient.
Replication
Replication is creating copies of your data, storing them, and efficiently handling them across different locations. For example, if your primary data center is in New York, you might replicate your data to another center in California or Dublin. This way, if one location is affected by a disaster, your data is still safe and accessible from another. Many organizations use cloud-based replication, which offers the benefit of cloud providers’ security features.
Firewalls
A firewall is a security system for computer networks that controls and limits internet traffic entering, exiting, or circulating within a private network. They inspect data packets flowing in and out of your network, checking them against your data protection rules. Its primary purpose is to prevent malicious activity and unauthorized web activities by anyone, whether inside or outside a private network.
There are different firewalls to consider:
- Network Firewalls: These sit at the edge of your network, filtering traffic based on IP addresses, ports, and protocols.
- Host-Based Firewalls: These are like personal bodyguards for each device, installed directly on laptops, servers, or other devices.
Firewalls aren’t a set-it-and-forget-it solution. Regular updates and monitoring will help you keep up with emerging threats.
Authentication and Authorization
Authentication and authorization safeguard automated data systems. These critical components protect data by verifying user identities and controlling access permissions. Think about a hospital or a data center. Authentication is like checking someone’s ID at the entrance, while authorization decides what parts of the building they can enter.
Authentication verifies a user’s identity through credentials like usernames and passwords or biometric data, such as fingerprints or facial recognition. This critical step safeguards systems, programs, and sensitive information from unauthorized access.
Multi-factor authentication (MFA) enhances security by demanding multiple forms of identification. To gain access, users must provide something they know (password), something they have (smartphone), and something they are (fingerprint). This layered approach makes it more difficult for intruders to compromise accounts using only a username and password.
Authorization determines and assigns permissions to verified users or systems, specifying accessible assets and permitted actions. Not everyone needs access to everything.
Role-based access control (RBAC) assigns permissions based on the user’s role, ensuring that people can only access the information necessary for their job. For example, a receptionist might need access to scheduling software but not financial records.
Identity and access management (IAM) systems help manage access to resources, streamlining the process of granting and revoking permissions. Microsoft Azure Active Directory and AWS IAM are preferred tools for maintaining a well-organized and secure access control system.
Endpoint Protectors
Your devices—like smartphones, tablets, and laptops—are often the weakest link in your security chain. Protecting these endpoints will help safeguard your information. There are various steps you can take to protect your devices:
- Antivirus and Anti-Malware: These programs constantly scan for and neutralize malicious software.
- Device Management: It helps enforce security policies across all devices connected to your network and protects your data in case of device theft, loss, or damage.
- Patch Management: Software isn’t perfect, and bugs or vulnerabilities can open the door for cyberattacks. Patch management involves regularly updating your software to fix these issues before hackers can exploit them.
Data Erasure
When it’s time to dispose of old devices or clean out your storage, you can’t just delete the files and call it a day. Deleting files often leaves data traces that data recovery tools can piece together. Proper data erasure permanently destroys your information.
How do you ensure foolproof data destruction?
- Secure Erase: Overwriting data with random patterns multiple times makes it nearly impossible to recover. It’s like shredding a document into tiny pieces and then scattering them to the wind.
- Physical Destruction: Sometimes, the best way to protect your data is to destroy the storage device itself. Crushing, shredding, or physically destroying hard drives and other media ensures no one can recover the data.
- Certified Data Destruction Services: If you want to ensure that your data is no more, you can hire a company that provides data destruction services. They’ll handle the process for you and provide a certificate as proof that they have deleted your data.
What is Mobile Data Protection?
Smartphones, tablets, and laptops are like digital extensions for many people. They use them for everything from texting friends to handling finances. But with all that convenience comes a big question: How do you keep sensitive information safe?
Mobile data protection involves implementing security measures to safeguard sensitive information on portable devices like laptops, smartphones, tablets, and wearables. A fundamental aspect of mobile device security is preventing unauthorized users from accessing your corporate network. It includes tools like encryption, remote wipe, which lets you delete all data on your phone if lost or stolen, and secure access controls.
Why is this important? Because mobile devices often connect to public Wi-Fi or where they’re more vulnerable to hacking or theft. Free Wi-Fi in a coffee shop or eatery allows easy access to your emails, bank accounts, and more. But with MDP in place, even if they took your phone, they’d hit a wall of security measures.
Who Needs Mobile Data Protection?
The short answer is everyone.
Whether you’re a student, a professional, or someone who likes to keep their photos and messages private, you must protect your portable devices.
For individuals, this means protecting personal details like social media accounts, online shopping information, and private conversations. Businesses have even more at stake—they need to protect customer data, trade secrets, and financial records. For example, consider a company that allows its employees to use their personal phones for work. The loss or hacking of those phones could affect the company, including financial losses and damage to its reputation.
Companies often use Mobile Device Management (MDM) to handle MDP. MDM lets a company’s IT department keep track of every mobile device used for work, whether owned by the company or the employee. They can enforce security policies like requiring strong passwords, encrypting data, and enabling remote wipe if a device is compromised.
Take remote work as an example. With more people working from home or on the go, businesses are more exposed to risks like data breaches. With MDM, organizations can ensure the security of work-related data, regardless of whether employees are connecting from their home Wi-Fi or a public hotspot.
Best Practices for Protecting Your Mobile Data
So, what can you do to protect your mobile data? Here are some tips:
- Use Strong Passwords and Biometrics: A strong password or biometric method is your first line of defense.
- Enable Encryption: Always encrypt your data. It keeps your information safe, even if someone has your device.
- Keep Your Software Updated: Software updates often include vital security fixes, so don’t ignore them.
- Be Cautious with Public Wi-Fi: Avoid accessing sensitive information when connected to public Wi-Fi networks. If you must use the network, consider using a Virtual Private Network (VPN) to encrypt your data.
- Educate Yourself: Stay informed about the latest security practices and be aware of phishing attempts and other scams that can compromise your mobile data.
Conclusion
With more services relying on online devices, it has become necessary for every person and organization to employ data security techniques. Implementing the data security and privacy tips outlined above allows you to reduce the risk of falling victim to cyber threats. Remember, it’s a shared responsibility. Businesses must also prioritize security measures, and individuals must cultivate a culture of digital vigilance.
Keep up with new threats and best practices. Ensure you consistently update your software, devices, and security for optimal performance. Be cautious about sharing personal information online, and always verify the authenticity of websites and emails. Above all, trust your instincts. If something feels off, it probably is.
