The following document is a practical guide to planning, checks and configuration changes required to help secure the IP Office solution. All IP Office existing and new installations, regardless of usage, must be assessed with the following sections and immediate action taken where indicated.

Implementing these recommendations will substantially reduce the risk of compromise from security threats such as Denial of Service, Toll Fraud and theft of data.

This document does not provide an analysis of security-related topics, define security policy or discuss theory – it also cannot guarantee security. This document does however aim to provide useful and understandable information that can be used by installation, service and support personnel as well as customers to help harden IP Office against attacks.
