Which statement about Webex Teams message encryption is valid?
A. Messages are encrypted using the AES-512-GCM cipher
B. Messages are encrypted using the AES-256-GCM cipher
C. Messages are encrypted using the AES-128-GCM cipher
D. Messages are encrypted ONLY if they include data classified as “confidential”
B
Letter “B” and “C” are correct Webex Teams support both, check teh “Cisco-Webex-Apps-Security-White-Paper.pdf”
Encryption Algorithms
Advanced Encryption Standard (AES)
The negotiable symmetric key encryption algorithms used between Webex Teams apps and Webex services use a subset of the Advanced Encryption Standard (AES) ciphers defined by the US National Institute of Standards and Technology (NIST):
• AES-256-GCM
• AES-128-GCM
• AES-256-CBC
• AES-128-CBC
