Secure by default, the Avaya second security layer, incorporates a hardened Linux operating system with inherent security features for Avaya Media Servers with Messaging. Avaya modifies the Linux kernel for secure, real-time telephony processing. The hardened Linux OS provides functions required to support core applications. These OS functions secure mission-critical call processing applications and protect you from toll fraud and other malicious attacks.
The Linux operating system that Avaya has hardened, limits the number of access ports, services, and executables. These limits help protect the system from typical modes of attack. Reduced Linux functions limit the requirement of mandatory security patches and protect against the risk of narrow vulnerability-to-exploit time window.
Messaging provides a range of inbuilt functions, which protect against threats from malicious software. These inbuilt functions minimize the need for a dedicated antivirus software that may reduce call processing efficiency and require attention to ensure the antivirus database is updated.
