Voice Security

IP Telephony is the term commonly used to define the transmission of phone calls over the Internet. This is regardless of whether traditional telephony equipment, computers and/or dedicated terminals take part in the calls and even if the phone calls are totally or partially transmitted over the Internet. IP Telephony is without doubt, one of the technological developments that are being rapidly adopted by companies nowadays.

IP Telephony and other pertinent services are real time in nature and a vital focal point for an organization adopting it, security of the same becomes of paramount importance. Moreover, because of IP Telephony’s inherent nature (which acts both in its favor and against it) it depends on the underlying network (OSI Layers 1 through 7) for its successful operation and functioning. In essence, IP Telephony networks are built on top of underlying network infrastructure and share the strengths and weaknesses of the data networks. This implies that IP Telephony networks are susceptible to attacks as much as its basic foundation: the data networks. To make matters worse, Voice over IP has its own set of security requirements, which can be exploited if left exposed.

The first and foremost question that may arise in your mind is, “Why should I even bother securing my IP Telephony network? It has been running fine, and I do not want to break something which is working by applying security.” It is a common misconception that applying security to an IP Telephony network will break it! The reality being that, a non-secure IP Telephony network is open to attacks and is prone to breakdowns.

You should secure your IP Telephony networks for the following reasons:

  • Secure IP Telephony infrastructure

Securing what is an asset to an organization’s daily life operations, without which the organization’s communications will crumble. This in turn has a domino effect as; the organization can experience disrupted communications with peers, amongst employees, with customers, and so on.

  • Secure the conversation

Ensure that your conversation is private and protected from eavesdropping or hacking of voice calls. Securing voice or video calls can help evade any chances of confidential information (being conveyed over an IP Telephony system) being eavesdropped, leading to Intellectual Capital theft, for example, eavesdropping of a conversation between a CEO and a CIO of a financial institution could otherwise reveal a lot of confidential information if it weren’t secure.

  • Business continuity

Ensures that the business continuity is maintained and the chances of disruption and losses are minimized. If voice and video conversations are secure, it helps ensure the business continuity and minimize disruption leading to monetary and credibility losses.

  • Business value

Protect your company’s privacy and intellectual property by protecting your IP Telephony communications. Lost business and trade-secret information, for example, pursuant to a man-in-the-middle (MITM) attack, could be worth a thousand leva to your company.

Keeping your voice communications safe from the same threats that can impact your data network is essential. In a world plagued with attackers and hackers, IP Telephony Security is an even more critical issue than ever before.
