Mitel Standard Linux and Antivirus Software Guidelines

Many of Mitel's real-time applications are designed to run on a purpose-built Linux operating system known as Mitel Standard Linux (MSL). MSL is based on the CentOS distribution with all unnecessary packages removed and certain services replaced to reduce the attack surface. Real-time applications such as MiVoice Business, MiVoice Border Gateway and MiCollab require unfettered access to processor resources, memory systems, disk drives and network communications. When these real-time applications are deployed on proprietary hardware, industry standard servers or virtual machines - as per Mitel's Engineering Guidelines - the underlying hardware resources (physical or virtual) have been sized to ensure that the applications will have the unrestricted and timely access to resources that they require.
