Definition of Data Protection

What is Data Protection?

Data protection refers to the security strategies and processes designed to secure confidential data against damage, compromise, and loss. Major threats to confidential data include security breaches and data loss incidents. Security breaches result from unauthorized access to your organization’s information, network, or devices, arising from cyberattacks, internal threats, or human errors. Besides data loss, the organization may suffer damage due to compliance violations, legal actions, and long-term reputation damage.

Threats to Confidential Data

A data loss incident can be an intentional or accidental interruption of an organization’s normal operations, such as the loss or theft of a laptop, software damage, or virus infiltration in the network. Establishing a security policy and training employees to recognize threats and respond appropriately is essential for data protection strategies.

Key Principles of Data Protection

Data Availability

Data availability ensures that employees can access necessary information for daily operations. Maintaining data availability contributes to the organization’s business continuity and disaster recovery plans. An essential element of data protection plans is using backup copies stored in a separate location. Access to these copies minimizes downtime and keeps operations on schedule.

Data Management

Data management includes managing the data lifecycle and information lifecycle. Data lifecycle management covers the creation, storage, use, analysis, archiving, or deletion of data, ensuring compliance with relevant regulations and avoiding unnecessary data storage. Information lifecycle management is a strategy for cataloging and storing information derived from the organization’s data sets, determining their relevance and accuracy.

Why is Data Protection Important?

Importance for Organizations and Users

Data protection is crucial to keeping the organization safe from data theft, leaks, and loss. It involves using privacy policies that meet compliance regulations and prevent reputation damage. An effective data protection strategy includes monitoring and protecting data within the organizational environment and maintaining continuous control over data visibility and access.

Consequences of Data Protection Breaches

Developing a data protection policy allows the organization to determine the risk tolerance for each data category and comply with applicable regulations. This policy helps establish authentication and authorization, determining who should have access to information and why.

Types of Data Protection Solutions

Data Loss Prevention

Data Loss Prevention (DLP) is a security solution that helps the organization prevent the sharing, transfer, or use of confidential data. Actions such as monitoring sensitive information across the data estate help comply with regulations like the Health Insurance Portability and Accountability Act (HIPAA) and the General Data Protection Regulation (GDPR).

Protected Storage

An efficient storage solution must provide data protection and allow recovery in case of deletion or modification. Multiple layers of redundancy help protect data against service interruptions, hardware issues, and natural disasters. Version control preserves previous states of data when an overwrite operation creates a new version. Configuring a lock (e.g., read-only or undeletable) on storage accounts protects against accidental or malicious deletion.

Data Discovery

Data discovery is the process of finding existing data sets in your organization in data centers, laptops, desktops, various mobile devices, and cloud platforms. Classifying data (e.g., marking as restricted, private, or public) and verifying its compliance with regulations are essential steps.

Backup

Backups fall under data management. They can be as frequent as desired (e.g., full backups every night and incremental backups throughout the day) and allow quick restoration of lost or damaged data, minimizing downtime. A typical backup strategy includes saving multiple copies of data and storing a complete set of backups on a separate server and another in an external location. Your backup strategy will align with the disaster recovery plan.

Disaster Recovery

Disaster recovery is an information security element focusing on how organizations use backups to restore data and return to normal operations after a disaster. This proactive approach helps the organization reduce the impact of unforeseen events and respond faster to planned or unplanned interruptions.

Snapshots

A snapshot is an image of the file system at a specific point in time; it preserves that view and tracks all changes made afterward. This data protection solution refers to storage arrays that use a collection of drives instead of servers. Arrays typically create a catalog indicating the data location. A snapshot copies an array and sets the data as read-only. New entries are created in the catalog, and old catalogs are preserved. Snapshots also include system configurations for server recovery.

Replication

Replication continuously copies data from one location to another to create and store an up-to-date copy of the data. This allows for failover in case the primary system fails. Besides protecting against data loss, replication makes data available from the nearest server so authorized users can access it faster. A complete copy of the organization’s data also allows teams to perform analyses without interfering with daily data requirements.

Firewalls

A firewall helps ensure that only authorized users can access the organization’s data. It works by monitoring and filtering network traffic according to security rules and helps block threats like viruses and ransomware attempts. Firewall settings typically include options for creating inbound and outbound rules, specifying security rules for logging, viewing monitoring logs, and receiving notifications when the firewall blocks something.

Authentication and Authorization

Authentication and authorization controls verify user credentials and confirm whether access privileges are correctly assigned and enforced. Role-based access control is an example of providing access only to those who need it to perform their work. It can be used with identity and access management to control what employees can and cannot access, keeping organizational resources like applications, files, and data safer.

Encryption

Encryption maintains the security, confidentiality, and integrity of data. It is used for data at rest or in transit, preventing unauthorized users from viewing file contents even if they gain access to their location. Plain text is transformed into unreadable ciphertext, which requires a decryption key to be read or processed.

Endpoint Protection

Endpoints are physical devices that connect to a network. These can be mobile devices, desktops, virtual machines, embedded devices, and servers. Endpoint protection helps the organization monitor these devices and protect them against threats that seek vulnerabilities or human errors and exploit security weaknesses.

Data Deletion

Data deletion removes stored data that the organization no longer needs. This process is also known as data purging and is often a regulatory requirement. Under GDPR, users have the right to have their personal data deleted upon request. This right to erasure is also known as the “right to be forgotten.”

Protection, Security, and Privacy

These might seem interchangeable terms, but data protection, data security, and data privacy each have a different purpose. Data protection encompasses the strategies and processes the organization uses to secure confidential data against damage, compromise, and loss. Data security focuses on the integrity of data and aims to protect it from damage by unauthorized users or internal threats. Data privacy controls who has access to data and establishes what can be shared with third parties.

Best Practices for Data Protection

Stay Current with Requirements

A comprehensive governance plan identifies regulatory requirements and how they apply to the organization’s data. Ensure you have visibility into all data and classify it correctly. Make sure to comply with privacy regulations in your industry.

Limit Access

Access control uses authentication to verify users’ identities and authorization to determine what information they are allowed to view and use. In case of a data breach, access control is one of the first policies to examine to ensure it was correctly implemented and maintained.

Create a Cybersecurity Policy

A cybersecurity policy defines and directs IT activities within the organization. It makes employees aware of common data threats and helps them be more vigilant about safety and security. Additionally, it can clarify data protection strategies and promote a culture of responsible data usage.

Monitor Activities

Continuous monitoring and testing help identify areas of potential risk. Use artificial intelligence and automate data monitoring activities to identify threats quickly and efficiently. This early warning system alerts you to potential security and data issues before they can cause damage.

Develop an Incident Response Plan

Having an incident response plan in place before a data breach occurs will prepare you to take action. This helps the response team (e.g., IT director, InfoSec, and communications director) maintain system integrity and restore the organization to normal as quickly as possible.

Identify Risks

Employees, distributors, vendors, and partners have information about your data, computer systems, and security practices. To identify unauthorized data access and protect it against misuse, you need to know what data you have and how it is used across the digital estate.

Improve Data Storage Security

Data storage security uses methods such as access control, encryption, and endpoint security to maintain the integrity and confidentiality of stored data. It also reduces the risk of intentional or unintentional damage and allows for continuous data availability.

Train Your Employees

Whether intentional or not, internal risks are a major cause of data breaches. Clearly communicate prevention policies regarding data at all levels to help employees comply. Repeat training frequently through refresher sessions and guidance when specific issues arise.

Compliance and Data Protection Laws

General Data Protection Regulation (GDPR)

GDPR is the strictest data privacy and security law. It was created and enacted by the EU, but organizations worldwide must comply if they target or collect personal data from EU citizens or residents or offer them goods and services.

California Consumer Privacy Act (CCPA)

CCPA secures privacy rights for California consumers, including the right to know about the personal information a business collects and how it is used and shared, the right to delete collected personal information, and the right to opt out of the sale of personal information.

Health Insurance Portability and Accountability Act (HIPAA)

HIPAA protects patient health information from being disclosed without the patient’s knowledge or consent. The HIPAA Privacy Rule protects personal medical information and was issued to implement HIPAA requirements. The HIPAA Security Rule protects identifiable health information that a healthcare provider creates, receives, maintains, or transmits electronically.

Gramm-Leach-Bliley Act (GLBA)

The Gramm-Leach-Bliley Act, also known as the Financial Services Modernization Act of 1999, requires financial institutions to explain their information-sharing practices to their customers and protect confidential data.

Federal Trade Commission

The Federal Trade Commission is the primary consumer protection agency in the United States. The Federal Trade Commission Act declares illegal unfair competition methods and unfair or deceptive actions or practices affecting commerce.

Data Protection Trends

More Data Protection Regulations

GDPR has become a benchmark for how other countries collect, disclose, and store personal data. Since its launch, the CCPA in the United States (California) and Brazil’s General Data Protection Law have been enacted to keep up with online consumerism and personalized products and services.

Mobile Data Protection

Preventing unauthorized users from accessing your network includes protecting confidential data stored on portable devices such as laptops, tablets, and smartphones. Security software uses identity verification to prevent device compromise.

Less Access for Third Parties

Data breaches often originate from third parties (such as vendors, partners, and service providers) who have too much access to an organization’s network and data. Third-party risk management is starting to appear in compliance regulations to limit how third parties access and use data.

Data Duplication Management

Data duplication management detects duplicated data, compares similar data, and allows the organization to delete unused copies of data. This solution minimizes inconsistencies caused by data duplication, reduces storage costs, and helps maintain security and compliance.

Data Portability

In the early days of cloud computing, data portability and migrating large data sets to other environments was challenging. Today, cloud technology makes data more portable, allowing organizations to move it between environments, such as from on-premises data centers to public cloud environments or between cloud service providers.

Disaster Recovery as a Service

Disaster recovery as a service helps organizations of all sizes use cost-effective cloud services to replicate systems and resume operations after a catastrophic event. This provides the flexibility and scalability of cloud-based technology and is seen as an effective solution to avoid service interruptions.

Data Discovery and Classification

Data discovery and classification are separate processes that work together to provide visibility into an organization’s data. A data discovery tool scans the entire digital estate to find where structured and unstructured data is located, which is essential for a data protection strategy. Data classification organizes the data from the discovery process based on file type, content, and other metadata, helping eliminate duplicated data and facilitating data management and protection.

Data Protection Solutions

Data protection solutions help protect against data loss and include security, data backup, and recovery, which directly support the organization’s disaster recovery plan. Simplify how the organization understands confidential data.

Final Conclusion

Data protection is a mandatory aspect of organizational management. Implementing effective strategies and processes to protect confidential data ensures legal compliance and protects against financial and reputational losses. By adopting best practices in data protection and using the right tools, organizations can maintain the integrity, confidentiality, and availability of data, ensuring operational continuity and trust from clients and partners.
