Data Privacy and Security: A Beginner's Guide

1. What is Data Privacy and Security?

Understanding data privacy and security is the foundation for protecting personal information in the digital world.

  • Data Privacy: The right to control how personal information is collected, used, and shared.
  • Example: Social media platforms collect user data to personalize ads and content.

These concepts are governed by laws like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA).

  • Two-Factor Authentication (2FA): Adding an extra layer of security to your accounts.
  • Phishing: A cyberattack method where criminals trick you into sharing sensitive information.
  • Data Breach: Unauthorized access to sensitive data, often due to weak security measures.

These concepts are supported by resources from the National Institute of Standards and Technology (NIST) and the Electronic Frontier Foundation (EFF).

These examples are based on research from the Pew Research Center and Consumer Reports.

6. Laws and Regulations

Several laws protect data privacy and security globally:
