Defending Against Direct Authentication Attacks in Microsoft Office 365

Whilst conducting security testing and assurance activities, I went looking to show logon events in Office 365. My first query was on IdentityEvents, this led to a view of a multi month attack by a threat actor/s against a tenent, followed by exploring the rabbit hole of logs and computer systems. This blog summarises some of the methods and findings when considering threat hunting and authentication defences for Office 365. (bear with me I am tired so this might need a bit of a tune up later!)

The Cyber Acid Test

I’ve been working with all kinds of different organisations over the years, and I keep running into similar scenarios.  The current state of the majority of organisations security postures are simply (as a broad-brush statement) far riskier than they need to be.

Conversely there are a range of common challenges I find in almost every org:

Service Security Architecture and Assurance

Have you every tried to understand the risk level of a service? Ever wanted to provide assurance to someone that “it’s been well designed, is secure from common threats, likely risk scenarios and is securely operated” etc.? have you ever tried to conduct testing against a service that is relatively unknown? Ever needed to actually do more than throw some packets at the front door? Guess what, I have. Most orgs don’t have a decent level of documentation on service architecture and security controls. And as the NSA nicely put, the way they get into networks is to know them better than you do! So in my travels I see lots of different orgs and largely there’s one common similarity, most of them aren’t well documented (docs are boring right!) and if we then make another huge sweeping generalisation, about 90% of orgs have security postures you wouldn’t want to have to defend as a blue teamer, but you might fancy if you were a nation state actor or cyber criminal!

UK laws and cyber security considerations for business

I am not a legal export! Haha get used to saying that a lot if you work in cyber and are not in fact a legal expert! I wanted to put together a list of common laws that people should be aware of when doing business in the UK, it’s just a starter for 10 and there are likely others, but this should get people started for their security awareness and security policy documentation:

Information Security Risk Management 

I wrote this in 2018 and don’t believe it ever made it to the interwebs, so I’m basically posting as is with an extra section for some useful links! Hopefully it still stands the test of time!

Risk Management doesn’t have to be risky! 

Risk assessments are complex, they require cross domain knowledge and generally do not deal in absolutes. Threats, vulnerabilities and asset intelligence is combined, weighed and assessed, leading to the construct of a risk assessment document. It can be easy to overcomplicate this process, which in turn (in my experience) often leads to far wider reaching consequences (the business starts to bypass security management or take short cuts), so I thought I would write a short post to clarify what I’ve seen work out in the field. So, to start with let’s try and align on what exactly a risk is.

Organisational Approach to Technology and Security

How an organization approaches the challenge of technology and security management, well that’s the difference between leveraging technology to deliver value efficiently and effectively vs technical debt and inefficient deployment of technology which may hinder the organisation in its pursuit of its mission.

When we consider how technology is managed, we need to look at it from multiple viewpoints with different views:
