Changing a security posture requires changing your own behaviours

I’m sure you will have had a marketing firm or some random sales person on Linkedin tell you that security should be simple and that their product will save you from all the ATPs and nation state hax0rs under the sun. However let’s get real, thats almost certainly not true and also security isnt simple or we’d all be out of jobs and everyon woulndn’t be getting owned all the time.

Cyber Security Assesments for Normal People

Ok so you might think I’m mad with the title but bear with me!

So, the world is in an interesting place, we’ve got a pandemic, we’ve got prolific cyber crime and we have all kinds of different views on how we should tackle this problem.

Now I love a framework and there’s ton’s of them. But the truth is they are complex, detailed, nuanced and generally require a level of nerd that a lot of organistaions do not have.

In 2020 during the pandemic I decided to try and write something to simplify this position, whilst I didn’t want to be too narrow, I wanted to try and capture the breadth of cyber security that is relevent to the general purpose organistaion. I came up with a set of 140 questions which I believe are a good take on things to consider and ask when conducting a security review at a high level. (yes 140 questions is a high level view, this stuff is complex as hell at the detailed end of things, and the devil is in the detail).

Cyber Defence is Hard

Introduction

If you read a book about management theory or specifically cyber security management you will find lots of frameworks, methods, formulas, models etc. None of them really let you know how insanely hard it can be to defend a moving target where regardless of how many controls you have, all it takes it someone doing something which may seem bonkers to you but perfectly reasonable for them. Their objective is to do business in an efficient manner, your objective is to protect the business in an efficient manner. Fundamentally these two things are not at odds, but there are a lot of human factors that come into play on top of some serious technical challenges. Read more “Cyber Defence is Hard”

The grass is always greener, until it is not

A PwnDefend Story – Day 7

It is a blur so far, I figured after the last place the grass would be greener, surely no one else has that many security challenges. I did some due diligence during the interview process, they seemed very confident about having certifications and that they took security seriously. hell, that should have set some red flags off but even the cynical sometimes hope that it is as someone says.

I have started to work myself around the board and I am making friends with people, my diary is filled with zoom calls and my notebook is already many pages deep.

You cannot make this stuff up though, day two and I’ve dealing with a business email compromise incident, the phishing page was not even in good English but then it only takes a second or so whilst in a meeting to not quite realise your running on autopilot so you cannot blame people. Hell, the branding was copied so we know it was a targeted phish. It would have been nice to at least had centralised logs for the team to analyse though.

Threat Modelling 101

What is a threat?

https://csrc.nist.gov/glossary/term/threat

According to those clever people at NIST it is:

“Any circumstance or event with the potential to adversely impact organizational operations (including mission, functions, image, or reputation), organizational assets, or individuals through an information system via unauthorized access, destruction, disclosure, modification of information, and/or denial of service. Also, the potential for a threat-source to successfully exploit a particular information system vulnerability.” Read more “Threat Modelling 101”
