Data encryption is the process of converting plaintext data into unreadable ciphertext to protect it from unauthorized access. The importance of data encryption cannot be overstated, as it plays a crucial role in ensuring the confidentiality, integrity, and authenticity of sensitive information. Here are some reasons why data encryption is essential:
- Confidentiality: Encryption ensures that only authorized parties can access the data, preventing unauthorized individuals or organizations from reading or stealing sensitive information.
- Data Protection: Encryption protects data from being tampered with, modified, or deleted by unauthorized parties, ensuring that the data remains intact and unchanged.
- Compliance: Many regulations, such as GDPR, HIPAA, and PCI-DSS, require organizations to encrypt sensitive data to ensure compliance and avoid fines.
