Security Modules

Security Modules are rack-mounted appliances that protect IP-based business communications against denial of service and information theft attacks.

Alcatel-Lucent Security Modules provide business continuity and information protection for Voice over IP business communications by offering software and protocol integrity protection as well as encrypted communications. The security architecture is based on technology from Thales® — a leading player in the security market.

A Server Security Module (SSM) protects business communications between Alcatel-Lucent Communication Servers and IP phones, IP media gateways and SIP trunks. Media Security Modules (MSM) protect communications with application servers that handle IP media flows such as recording, messaging or conferencing servers.
