How Secure Is Video Conferencing?

Secure Video Conferencing

Video conferencing security isn’t just in the best interest of the client. It is now a legal requirement for the provision of video conferencing solutions. Recent regulations state that all electronic client data must be secured to ensure the security of the client. Transmission data such as video conferencing also falls under this category. Because of that, video conferencing security has become one of the quickest growing parts of the video conferencing industry. No company wants to be caught without a working security solution, and so they work very hard to maintain the security and integrity of their data networks. Data security is of the utmost importance when it comes to video conferencing. To this end, in order to understand video conferencing security used by top notch companies like Blue Jeans, we must first understand the basics of how video conferencing solutions deal with securing their connections.

The Basics of Connection Security

For a secure connection to exist there must be protocols in place for securing both the data transmission that goes on in a live stream as well as the data storage of the recorded session after the meeting has taken place. While the meeting is taken place, the connection is encrypted to ensure that outside parties cannot tap directly into the broadcast stream. This encryption can be either 56-bit or 128-bit in nature. 128-bit encryption is almost unbreakable as it guarantees 3.4x x 10^38 possible combinations for any particular sequence of bits. When the meeting is concluded the recorded data is stores in a specially secured off-site location that can only be accessed by a number of security checkpoints and fail-safes. This ensures that both the transmission and recoded versions of the meeting are kept in a state of high security. It allows subscribers to breathe easy knowing their business information is so well secured.

Understanding Data Radiation

Another very possible reality is that the equipment that is used in video conferencing “radiates” the data, making it possible for other parties to eavesdrop on a teleconference simply by tuning in to the right frequency. All electronic devices have a certain level of background radiation. In the case of video conferencing hardware, this radiation can consist of the information that the equipment is transmitting to the receiving end. This information is not encrypted (since this emission happens before encryption takes place) and the unencrypted data is ripe for anyone with the right equipment to listen in on. Luckily in the case of most video conferencing equipment in this day and age, radiation is not a problem for them since they fall under the strict guidelines set forth by the Joint Interoperability Test Command (JITC) called TEMPEST. These allow for a certain level of radiation emissions for equipment that is too low to pose a danger of interception.

Other Security Methods

There are a number of other security methods that personnel can try in order to increase the level of security of a system dealing with teleconferencing. However, because these methods are heavily dependent on the expertise of the technician in question. Direct dialing from the IMUX is one of the possible solutions to creating a secure connection. Although it is highly secure, it requires special understanding and expertise to switch modes from secure to unsecure and back again. Using the IMUX is an option that requires hard wiring the changes every time it needs to be done. An alternative to this is by instituting an optical dial isolator. This piece of hardware removes the need for security for a system by removing radiation from copper wires completely. it replaces the copper wires by fiber optic cables and increases the speed and security of the transmission many times over. Using this piece of hardware enables a company or governmental body to easily swap between secure and unsecure calls as the case may be.

From what we have seen, video conferencing can be one of the most secure methods of conducting a meeting over a long distance. In fact, it can even be more secure than having the meeting take place in person. The levels of security active in an online video conferencing session is quite a lot more than any security that may be present for a meeting that takes place physically. It also has the added security feature of backing up the video so that it can be used to create the minutes of the meeting for the next meeting to have footnotes on what happened previously. This stored version is also highly secure, making for a formidable wall to anyone or anything that seeks to gain unauthorized access to a company’s meeting data. This is technology of the future working to secure your business interests today. It is only a matter of time before video conferencing will be accepted as a part of corporate life and by understanding how your video conferences are secured, you can make an informed decision as to which company provides the best levels of security that your company can utilize for their own ends.
