LastPass Breach – The danger of metadata

When an organisation suffers a data breach it’s usually bad. When an organisation that stores 25 million people’s passwords that’s really bad.

There are multiple risks here at play.

Firstly, when we give people our data, it’s our risk and our choice. I’m ok with that, I chose to give lastPass my data.

My vault data might be gone, but I have a strong master password, how we interpreted the theft of the basically cryptographic materials is a bit like when we full disk encrypt a drive.

If you lose a laptop that’s got FDE do you report this as a data loss to the ICO? Or do you say, it’s encrypted so actually I haven’t lost the data per say, I’ve just lost a random (ish) bunch of 0s an 1s so I don’t count that as an incident? I’m not here to be judge or jury.

What is a “Winning Cyber Security Strategy”?

A winning cyber security strategy should have several key components.

First, it should involve a thorough assessment of your organization’s current security posture, including identifying any potential vulnerabilities or weaknesses. This assessment should be ongoing, with regular updates to ensure that your security measures are keeping pace with the evolving threat landscape.

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!

Enterprise Technology Generalisations

I’ve waked around one of two organisations, across a load of verticals and well I see people post things online about common technology generalisations and frankly it sometimes leaves me wondering what networks they have been in, but also am I just on another planet? So, I thought I would jot down some notes on common tech I see in orgs during my business travels but also on in the ciberz! It’s not a list of everything I see, it’s just what appears in my head as quite bloody common.

How to not lose your job as a CISO

A mRr3b00t Adventure

Join me on an adventure of rambling and exploring the idea that you can in fact not lose the security leadership game! This blog is WIP, it’s just my brain wondering around the question of: can we win the in the face of a seemingly insurmountable force? What do we do as a security leader to protect ourselves and the organisation? How do we start?

Red Team Readiness Assessment

I am seeing lots of “debate” about the value in red teaming, so I thought I would put together my thought process of how I look at as a broad stroke when I consider a generic starting position in an organisation. When I’m defending a business, I tend to ask myself (and the team/customers etc.) these kind of questions (they are not exhaustive):

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:

Data Protection Act 2018
Freedom of Information Act
Communications Act
Computer Misuse Act 1990
Investigatory Power Act 2016 (IPA)
Theft Act 1990
Terrorism Act 2000
The General Data Protection Regulation (GDPR)
The Privacy and Electronic Communications Regulations 2003 (PECR)
The Regulation of Investigatory privacy Act 2000 (RIPA)
Official Secrets Act 1989 (OSA)
Companies Act 2006
Copyright and Design patents Act 198
Trademarks Act 1994
The Malicious Communication Act 1988
Forgery and Counterfeiting Act 1981
Police and Criminal Evidence Act 1984
Contracts (Rights of Third Parties) Act 1999
Fraud Act 2006
Network and Information Systems Regulations 2018 (NIS)
Telecommunications (Security) Act 2021
The Bribery Act 2010
Freedom of Information Act 2000
Defence of the Realm Act 1914

can you think of any others that I should add?

Thanks Gary and Kevin and the other AVIS I can’t name for inputting!

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.

Defense

Broadband Routers

When it comes to digital technology, we have to consider many things.

Availability, Confidentiality, and Integrity are good building blocks for considerations. We can probably split this into two major views to start with:

What does a typical consumer care about?
What security and privacy considerations could be made?

A typical consumer may be about:

Availability
Cost
WIFI Coverage
Performance
Ease of Use
Ease of Support/Troubleshooting
Style/Looks
What happens if it breaks?
Can I stop my kids messing with it? (Probably not so why bother)

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:
