Encrypting data in transit (HTTPS, VPNs, secure email)
Encrypting data in transit (HTTPS, VPNs, secure email). Encryption converts data into unreadable format without the proper key, protecting confidentiality. Common use cases: Data at Rest: - Full Disk Encryption: BitLocker (Windows), FileVault (Mac) encrypt entire hard drive. If laptop is stolen, data is protected. - Database Encryption: Encrypt sensitive columns (SSNs, credit cards) so even if database is accessed, data can't be read. - File/Folder Encryption: Encrypt specific sensitive files (7-Zip with password, VeraCrypt). - Device Encryption: Phone/tablet encryption protects data if device is stolen. Data in Transit: - HTTPS: Web traffic encrypted with TLS. Look for padlock icon. Protects login credentials, credit cards.
