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.
