The importance of cybersecurity has grown exponentially over the last decade. Today, data security and privacy are popular within data security regulations that impose strict penalties on companies that ignore ongoing threats from cyber attacks such as malware and intruders. It's still the hottest topic for IT professionals. But even some IT professionals aren't clear about the difference between data privacy and data security. This week's blog post explains the similarities and differences between these terms.
What Is Data Privacy?
Privacy ensures that unauthorized parties do not have access to your information and that you continue to control your personally identifiable information (PII). Therefore, Data privacy primarily deals with procedures and policies governing the collection, storage, and use of PII and proprietary company information such as trade secrets, personnel, and internal processes. PII is highly confidential because of the civil and criminal liability companies and individuals face if improper disclosure is allowed overtly or due to unintended data security breaches.
Data breaches are no longer just embarrassing or inconvenient for businesses. Currently, privacy laws such as GDPR impose penalties for failing to protect the privacy of PII and other sensitive personal information. These compliance standards may impose financial penalties and criminal charges for PII's intentional and, in some cases, unintentional disclosures. GDPR imposes privacy standards and legal requirements on all companies that store or process the personal information of EU residents.
What Is Data Security?
Data security uses physical and logical strategies to protect information from data breaches, cyber-attacks, and accidental or intentional data loss. Specifically, technologies and techniques used to prevent:
- Unauthorized access
- The deliberate loss of sensitive data
- Accidental loss or corruption of sensitive data
Examples of measures to ensure data security include data encryption, both at rest and in transit, and physical and logical access control to prevent unauthorized access. Specific techniques include multi-factor authentication, multiple layers of network and application-level access control, and detection and isolation of rogue devices after connecting to the network. Regular backups and a proven disaster recovery plan are essential parts of data security.
In short, data security is based on a technically sophisticated and comprehensive approach to protecting all networks, applications, devices, and data stores within an enterprise IT infrastructure.
