AES: Advanced Encryption Standard in Cybersecurity
AES stands for Advanced Encryption Standard. AES is a symmetric block cipher adopted by the U.S. government as the standard for encrypting classified data. It supports 128-, 192-, and 256-bit key lengths.
How AES Is Used in Cybersecurity
Cybersecurity teams use AES to encrypt data at rest on servers, databases, and endpoints. Security engineers select AES-256 for disk encryption, VPN tunnels, and TLS cipher suites. GRC analysts verify AES usage during compliance audits for standards like PCI DSS and HIPAA.
