VoIP and Communication Security: Potential Scenarios and Easy Solutions

VoIP, also known as Voice Over Internet Protocol is a mode of internet telephony that has been adopted my hundreds of thousands companies in the country and across the world since the turn of the century. The availability of the internet in all corners of our nation has made it possible for whole offices to unshackle themselves from heavy telephone sets as well as unsightly wires and unnecessary call centers in favor of a more portable, convenient, reliable an affordable service which uses the internet to transport voice and data in small-size data packets. That being said, there are a lot of security vulnerabilities that one may face if they haven’t done their research before settling on a trusted VoIP provider. VoIP Security Basics The internet can be looked at as the last remaining Wild West on account of the number of hacking events and vulnerabilities to whole IT infrastructures. VoIP is not immune to these events, and it’s not impossible for hackers or business rivals to try to bring your VoIP network down in order to acquire valuable data or slow down your success.

  1. Distributed Denial of Service Attacks, commonly known as DDoS attacks typically involve hackers getting into your network and bombarding it with packets of data in order to execute certain commands. DDoS attacks can make your VoIP phones ring endlessly, change automated instructions and even make it impossible to retrieve voicemail and other important business-related information.
  2. Eavesdropping into conversations is yet another way one can have their VoIP service compromised. This typically involves unauthorized individuals deploying a voice packet capture tool into your network and recording sensitive information that may put your company in jeopardy.

How to Secure VoIP Networks By doing adequate research, you’ll be able to secure your VoIP network from these and many more attacks in the future. Let’s take a look at some of the pre-emptive measures that you can easily use to secure your VoIP network.

  • Authorization is a simple and practical way of securing your connection. This typically requires you to set certain parameters to only accept calls and data from certain IP addresses, bypassing those that have a history of deploying attacks.
  • SRTP, also known as Secure Real-Time Transport Protocol is an encryption mechanism which changes incoming messages, encoding them and only making them readable to people who have a certain key.
  • Authentication is yet another way of securing VoIP networks which involves two communicating devices identifying each other via a secret word or code before communication begins.

Instead of winging it when it comes to your VoIP options, it’s best to go with a tried and tested telephony service.
