What type of encryption is recommended by Avaya for secure communications?

AES (Advanced Encryption Standard) is recommended by Avaya for secure communications due to its strong security features and efficiency. AES is widely recognized for providing a high level of security while being faster and less resource-intensive compared to older encryption standards. It uses key lengths of 128, 192, or 256 bits, which allow for robust encryption capabilities.

Unlike DES, which has become outdated due to vulnerabilities and its shorter key length of 56 bits, or Blowfish, which, while still secure, is less commonly supported and has its limitations in scalability, AES has been adopted as a standard by various security organizations, including the US National Institute of Standards and Technology (NIST). This widespread endorsement and its ability to handle large amounts of data securely make AES a preferred choice for communication security in Avaya systems and other applications.
