As many of you know, I spent some time researching the CSL CS2300-R SPTs last year. I found a series of issues that I think are serious problems. CSL have had 17 months to deal with these issues, and after them dawdling, I opted for co-ordinated disclosure of the issues via CERT/CC.

 

CSL have had 45 days to respond to CERT/CC, and only did so on Friday with a statement that is largely spin and distraction.

 

In summary, the issues found:

  • CSL have developed incredibly bad encryption, on a par with techniques state-of-the-art in the time before computers.
  • CSL have not protected against substitution very well
  • CSL can’t fix issues when they are found because they can’t update the firmware
  • There seems to be a big gap between the observed behaviour of the CS2300-R boards and the standards
  • It’s likely that the test house didn’t actually test the encryption or electronic security
  • Even if a device adheres to the standard, it could still be full of holes
  • CSL either lack the skill or drive to develop secure systems, making mistake after mistake
I have written a blog post detailing these issues, which also links to the full PDF report.

 

Until CSL can demonstrate that their products are standards compliant and secure, I would advise not using them, especially for higher grades.

None of us are pretending anything, there has been and all ways will be ways around security systems, so long as the kit is one step ahead of the type of burglar expected then whats to worry about?  I

It has to be the manufacturer for allowing such inferior equipment to be released. Everyone else down the line has worked on trust.

Bag and cat spring to mind though. Things might and should change. As an end user I'd be livid with the findings too. Having said that, I'm not an end user of said equipment and I'm not surprised with

Is the 2300 the board in grade 3 mode?

The only difference between the grades is the reporting time, as far as I can tell.

The encryption, the protocol, the lack of firmware updates etc. are the same regardless of grade.

cg what responses have you had from csl regarding this?

They haven't communicated with me at all since they tried getting my home address 6 weeks ago.

its a bit over my head but can the unit be defeated in the field without access to the unit itself?

I believe it can, yes. Certainly the ones that use the IP path can be sniffed and spoofed with little trouble. The problem is that I can't push the boundaries any further to prove it.

The real point is that their systems have been designed and operated by people who very clearly are incompetent. If anyone has looked at their security, CSL have totally ignored any findings. God knows what else is there. If you aren't regulated by the law, it could be awful.

to assist? in what way?

 

Dualcom are a BSIA member and the BSIA have a lot to do the the standards dont they? so they could explain the standards to them.

 

The next thing you will be telling me is grading of CCTV is coming in http://www.bsia.co.uk/Portals/4/Publications/218-CCTV-graded-requirements.pdf

Who did they try to get your address from? I hear if you boil the horses head it makes quite a pleasant soup.

Me. For "formal communications". Seems odd, as I am a business.

The law.
