Note

Phone hardening

The Cisco IP Phone can use 802.1X authentication to request and gain access
to the network.

802.1X Authentication

When connected to Cisco Unified Communications Manager Release 10.5(2)
and later, the phones support AES 256 encryption support for TLS and SIP
for signaling and media encryption. This enables phones to initiate and
support TLS 1.2 connections using AES-256 based ciphers that conform to
SHA-2 (Secure Hash Algorithm) standards and are Federal Information
Processing Standards (FIPS) compliant. The new ciphers are:

•

For TLS connections:

◦

TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384

◦

TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256

•

For sRTP:

◦

AEAD_AES_256_GCM

◦

AEAD_AES_128_GCM

For more information, see the Cisco Unified Communications Manager
documentation.
