A third party view on the security of the Canaries

(Guest post by Ollie Whitehouse)

tl;dr

Thinkst engaged NCC Group to perform a third party assessment of the security of their Canary appliance. The Canaries came out of the assessment well. When compared in a subjective manner to the vast majority of embedded devices and/or security products we have assessed and researched over the last 18 years they were very good.

Who is NCC Group and who am I?

Firstly, it is prudent to introduce myself and the company I represent. My name is Ollie Whitehouse and I am the Global CTO for NCC Group. My career in cyber spans over 20 years in areas such as applied research, internal product security teams at companies like BlackBerry and, of course, consultancy. NCC Group is a global professional and managed security firm with its headquarters in the UK and offices in the USA, Canada, Netherlands, Denmark, Spain, Singapore and Australia to mention but a few.

What were we engaged to do?

Quite simply we were tasked to see if we could identify any vulnerabilities in the Canary appliance that would have a meaningful impact on real-world deployments in real-world threat scenarios. The assessment was entirely white box (i.e. undertaken with full knowledge and code access etc.)

Specifically the solution was assessed for:

·       Common software vulnerabilities

·       Configuration issues

·       Logic issues including those involving the enrolment and update processes

·       General privacy and integrity of the solution

The solution was NOT assessed for:

·       The efficacy of Canary in an environment

·       The ability to fingerprint and detect a Canary

·       Operational security of the Thinkst SaaS

What did NCC Group find?

NCC Group staffed a team with a combined experience of over 30 years in software security assessments to undertake this review for what I consider a reasonable amount of time given the code base size and product complexity.

We found a few minor issues, including a few broken vulnerability chains, but overall we did not find anything that would facilitate a remote breach.

While we would never make any warranties it is clear from the choice of programming languages, design and implementation that there is a defence in depth model in place. The primitives around cryptography usage are also robust, avoiding many of the pitfalls seen more widely in the market.

The conclusion of our evaluation is that the Canary platform is well designed and well implemented from a security perspective. Although there were some vulnerabilities, none of these were significant, none would be accessible to an unauthenticated attacker and none affected the administrative console. The Canary device is robust from a product security perspective based on current understanding.

So overall?

The device platform and its software stack (outside of the base OS) has been designed and implemented by a team at Thinkst with a history in code product assessments and penetration testing (a worthy opponent one might argue), and this shows in the positive results from our evaluation.

Overall, Thinkst have done a good job and shown they are invested in producing not only a security product but also a secure product.
