# Security - Overview

Server security refers to protecting your NuPoint Unified Messaging server from abuse, both from outside callers and from mailbox owners. Outside callers can attempt to “take over” mailboxes that can be reached through the public switched telephone network and use them for their own applications. Mailbox owners can make inappropriate use of server resources by placing long distance calls through the server, overusing available storage, or sending messages to mailboxes that should be “off limits.”

The server has many features that are designed to provide security at the server level and at the mailbox level. These features address server administration, mailbox usage, and access to facilities, applications, and information.

This section describes the following features:

- Protecting your server from outside abuse

- Protecting your server from abuse by mailbox owners and users

- Protecting the server maintenance and administration functions

- Security reports and audit trails

- Functionally Partitioned System Administration (FPSA)
