Secure Service Design: Practical Solution Architecture

The truth shall set you free

I’ve worked in technology a long time now (relatively for me). It’s now over 20 years professionally and when I was a kid, I used to remove malware from small business’s etc. I’ve travelled to some funky places and done some cool things, but I learn new things every day. I do however come across some repeating patterns in my adventures as a consultant. There is a hidden truth that many are scared to admit…

Most organisations are not very good at service design, let alone secure service design!

Ok so there it is, I hope that this blog doesn’t age very well, but I’m 20 years in and I chat with my dad about his past life in the corporate world and we both see the same things being repeated. So, what can we do about it? Well sharing is caring, so here’s some things to think about when planning and designing a new service. I’m going to focus on the technology and security aspects, clearly, I am not saying ignore the business and value alignment but for the purposes of this post I’m assuming that the functional service capabilities and alignment are in effect. I’m also assuming that business case is solid because you know, without £ it’s a bit hard to create an operate a service (that’s a whole new post!).

Everything must be agile but is that really always…

A lot of people talk about AGILE but the normally mean ‘agile’ however when it comes to security testing and penetration testing (to me there is most certainly a difference) we need to be mindful of the different approaches, so we select the right one for the context, scenario, and objectives.

In this post we take a brief look at what we recommend for a range of scenarios and we look at the key differences and what some constraints might mean when it comes to approach selection.

Make Logging Great Again (MLGA)

Ok so i’ve been showing how alot of things do NOT get audited in Windows out of the box (on Twitter obviously) so I thought I’d export the CSV which you can import to enable some of the advanced logging features into a GPO without so many clicks (RSA sucks!)

So here is a CSV file that you can use to import! this isn’t everything you need to do, but it’s a start!

Hunting a breach… CVE-2020-5902

I’ve spent the last 24 hours (including a sleeps) gathering intel, testing in the lab and looking at what the path traversal and RCE for the F5 BIG-IP as outlined in CVE-2020-5902 looks like.
Well I’ll be honest.. the whole scenario is a bit of a bloody mess! We’ve got people leaving management interfaces exposed to the internet, we’ve got a vulnerability that’s incredibly old in a security appliance (it’s not exactly uber 1337 either) and we’ve had the release scenario that’s probably ruined peoples weekends and weeks (I’m not going into an Offensive Securitry Tools debate/argument, if you want that go talk to a brick wall or someone else!)
