What security measures are necessary to protect data?
Data security involves protecting data from unauthorized access, modification, and disclosure. Key security measures include:
- Encryption: Encodes data using an encryption key, making it unreadable without the key. Data should be encrypted both at rest (stored data) and in transit (data being transferred).
- Access controls: Restrict access to data based on roles and permissions, ensuring only authorized individuals can access sensitive information.
- Data masking/obfuscation: Replaces sensitive data with synthetic versions, protecting privacy while maintaining data utility for testing and training purposes.
- De-identification: Removes personally identifiable information (PII) from datasets, reducing privacy risks when sharing data externally.
