Wi-Fi and Security Considerations for ClickShare

Page 11 of 14

he security of a product or system can be viewed from

several different angles. In the following sections, we cover

various security concerns that people may have with

ClickShare.

1. Introducing malware on the client PC

2. Tapping into content shown by ClickShare

3. ClickShare disturbing other parts of the IT environment

4. Secure management interfaces

5. External parties disturbing the meeting

6. Logging

7. Security benchmarking

The only software running on the client PC is the ClickShare

Client software (the “Client”). This piece of software is

developed and maintained in-house by Barco – no external

party has access to this software. Furthermore, the binary

software image is compressed and signed before it is sent to

the factory that produces ClickShare.

The software is stored on a mass storage device inside the

ClickShare Button which is read-only during normal use. It can

only be programmed by the factory, or re-programmed by the

ClickShare Base Unit (a normal user cannot write to this

storage device, intentionally or unintentionally). In the case of

re-programming, this is done by software running on the Base

Unit, which is also developed and maintained in-house by

Barco.

The software is never installed on a client PC (which affects

permanent storage and configuration); it is merely run on that

PC (which only affects volatile RAM memory and the CPU). The

software does not require any special drivers to be installed on

the PC and does not install any drivers itself.

Thus, it is virtually impossible for malware to enter the client

PC through the ClickShare Button.

No files are streamed or sent from the client PC to the

ClickShare Base Unit – only the visual information as rendered

locally on screen is transmitted through the ClickShare Button.

The transmission of this visual information is done inside a

WPA2-encrypted Wi-Fi channel.

Therefore, tapping into this information stream to recover the

original data is virtually impossible.

Moreover, as the Base Unit is an endpoint for the stream, the

information sent to the Base Unit is not sent back to any of the

client devices.

ClickShare can have a number of interface points to the rest of

the IT environment. However, ClickShare has been designed

not to disturb other parts of the IT environment. The interface

points are:
