In management, you likely often find yourself confronted with the question of which technology trends should be introduced into your business. While the trend digitalization is now an everyday reality in most businesses, “Bring Your Own Device (BYOD)” is still a hot topic of discussion - and not without good reason.
BYOD refers to the current developments going on in many businesses whereby staff are permitted to use their own personal devices for work purposes. According to reports, this concept has allowed many businesses to kill two birds with one stone: The amount spent on IT can be significantly reduced, and even more interesting for many businesses, staff satisfaction increases.
Fundamentally, BYOD makes it easier to work from home since there is no longer any need to switch between personal and work equipment - flexibility that many workers repay in the form of increased productivity.
Increasing interest in also using BYOD in meeting rooms, has seen a growth in the popularity of wireless presentation systems. These systems allow fast and simple screen mirroring.
However, the introduction of any new IT solution always brings with it security concerns. Confidential data and information needs to be protected from unauthorized third party access.
Finding a solution to this issue was the fundamental idea behind the development of BenQ InstaShow®: a wireless presentation system combined with a high standard of security.
How does BenQ InstaShow® ensure this high level of security?
1. InstaShow® is an entirely hardware-based solution and no installation is necessary.
In order that as many devices as possible can connect to a wireless presentation system, designs using a dongle and a single USB type A connector were created. However, such designs present security risks. The use of a USB connection means that software is required to convert data into an audio/video format. This design is problematic in various ways:
- Third party software can contain security risks for your IT infrastructure. It is therefore recommended to thoroughly inspect software for malware and security holes before purchase.
- Manufacturers use USB dongles in “mass storage device” mode in order to automatically install software onto a device. As with any USB stick, the dongle can also be loaded with malicious software from third parties. This can make devices and potentially even entire company networks vulnerable.
InstaShow® does not contain a USB mass storage device, instead using USB purely as a power source. You can easily see this by the two power supply pins on the InstaShow® USB plug.
2. Secure HDMI data connection with HDCP encryption
- Unlike other manufacturers, BenQ uses a High-Definition Multimedia Interface (HDMI) connection for data transfer, not USB. Several aspects of the HDMI standard are beneficial to security:
- HDMI can only send data in one direction - from the device to the display: This prevents any kind of attack on the device being possible.
- HDMI is used exclusively for transferring video and audio data. This means that unwanted data packets cannot be injected into the stream as is possible with USB.
- InstaShow® uses the Digital Content Protection (HDCP) HDMI encryption system.
Data leaks are a serious concern for BYOD
Many companies have reservations about introducing BYOD. As they are unable to manage employees’ personal devices, they are concerned about data leaks and data loss. Such security holes can quickly get out of control. Leaks of company secrets, intellectual property, or confidential customer information will damage the reputation of a company, considerably in some cases. But BYOD doesn’t need to be this complex or daunting - the main thing is to put in place a clear BYOD policy. This may include things such as network and access control systems. IT security policies should be expanded to include mobile devices that usually connect using Bluetooth or WiFi.
BYOD and wireless presentations in meeting rooms
As someone who is always up-to-date with current trends, you maybe interested in a wireless presentation system. Wireless HDMI presentation systems that enable the use of BYOD in meeting rooms are becoming increasingly popular. This is because they make it quick and easy to share content via a wireless HDMI connection using a personal laptop. These systems are especially practical when holding a large conference with many speakers. Thanks to the use of plug-and-play technology, it is easy to set up - no additional software or drivers need to be installed. Just one press of a button is all that is needed to start the presentation!
In order to ensure your data stays safe, you should choose a purely hardware-based wireless presentation system. This is because wireless HDMI presentation systems such as the BenQ InstaShow® are 100% secure: Encrypted data is sent exclusively from the transmitter to the receiver. Visitors also benefit from this solution as they don’t need to spend time and effort installing any software before being able to give their presentation. Furthermore, a connection to the company network is not required, minimizing the risk of an attack.
Conclusion
Thanks to the hardware-based design using HDMI, BenQ InstaShow® WDC10 is the ideal companion for security-conscious, modern businesses looking to get into BYOD.
