VoIP Security Best Practices: Preventing Attacks and Managing Risk

By leveraging IP PBX to handle calls using voice over IP (VoIP) and adding unified communications (UC) applications, enterprises can decrease costs, improve collaboration and ensure business continuity. However, enterprises need to fully realize the security implications of extending their VoIP/UC over untrusted networks. To extend VoIP/UC securely, there are a number of best practices that must be followed to prevent attacks and minimize risk. Some of these best practices can be borrowed from the data world, but new VoIP/UC-specific security best practices must also be deployed.

Enabling Security for VoIP Remote Users White Paper

It is clear that the enterprise has no choice but to extend its IP PBX to remote users, road warriors, and even supply chain partners to realize the full benefits of unified communications. However, the Internet is an insecure means of transmitting data, and a variety of publicized attacks and viruses have made it painfully obvious that this is true. VoIP remote users require more security than ever before.

Traditionally, Virtual Private Networks (VPNs) and other security products, such as firewalls, have been deployed to
create a secure tunnel across the Internet and to protect the enterprise against attack. But are traditional data security products such as Internet Protocol Security (IPSec) VPNs able to handle VoIP remote users, or do you need VoIP-specific products? Are IPSec VPNs even an option for unified communications on a mobile phone or hard phone? What are all the security issues that need to be addressed to enable VoIP remote users?
