What is Encryption in Cybersecurity?
Encryption converts plaintext data into ciphertext using a mathematical algorithm and a key, making it unreadable to anyone without the corresponding decryption key. It protects data confidentiality both at rest (stored files, databases) and in transit (network traffic, emails).
Why Encryption Matters for Your Cybersecurity Career
Encryption is the foundation of data protection in cybersecurity. Security engineers implement encryption across systems to meet compliance requirements like HIPAA, PCI DSS, and GDPR. GRC analysts audit encryption controls. Every cybersecurity professional needs to understand when and how encryption should be applied.
