Understanding Cisco Unified Communications Manager Express Security – Voice Encryption

Voice over IP (VoIP) is not just need of hour for most enterprises; it’s something their business depends on to a degree that without IP communications in place, their business processes and revenue streams will fall apart. In such case, it goes without saying; security of voice networks is one of the chief concerns when it comes to security of intellectual capital and customer data. More often than not, one of the first thoughts is how to secure the VoIP network itself which is leveraged by IP Telephony / Unified Communication (UC) applications.

So what is that may be the most commonly sought after yet elusive security control which plays an indispensable role in securing a VoIP network? Your guess is as good as mine, it is encryption! Now, you are well within your rights to ask why elusive? The simple answer is – where encryption can help you succeed and protect the privacy of communications, it can also be detrimental for various functions / organizations e.g. monitoring secure calls is not a trivial task and encrypting all endpoints has an impact on platform sizing and performance.

In this article we discuss about the security of Cisco Unified Communications Manager Express (CUCME) which is an integral part of Cisco UC; and more so of Cisco Express Call processing regime.

Best Practices for Deploying Secure Cisco IP Telephony Solutions

IP telephony is slowly but surely becoming part of the modern day organization’s day-to day-operations. In fact, some organizations depend on it to the extent of their core business or processes based on IP communications. Sadly though, the security aspect pertinent to IP based communications network, applications, and underlying infrastructure is usually not taken into consideration (or is ignored) when enterprises and businesses think of deploying unified communications.

On the same lines of thought, why should anyone for that matter think of securing an IP telephony network? The answer is simple however manifold:

  1. To protect the information flowing in IP communication channels from eavesdropping and reconnaissance attacks as well as from manipulation or injection attacks.
  2. To ensure that the investment in their on-premise or off-premise infrastructure pays off (ROI) and doesn’t end up in a rogue’s hands, utilizing it for malicious purposes.
  3. To lower Total Cost of Ownership (TCO) by leveraging IP communications to offset PSTN/Toll calls and reducing Moving, Addition, Configuration, and Deletion (MACD) and at the same time, keeping conversations safe.
  4. Attacks on the telephony network may result in monetary and reputation loss. Moreover, it can directly or indirectly impact the business continuity and clientage.

Today, many organizations depend on a number of IP telephony services like voice calls, instant messaging, conferencing, and video conferencing. A typical IP telephony network can face several threats like toll fraud, reconnaissance attacks, eavesdropping, Denial of Service (DoS) attack, and call hijack. While most organizations do consider that their network needs protection from internal or external threats, such a notion is missing (usually) when it comes to their IP telephony applications/devices.
