CREATING GOOD POLICIES AND PROCEDURES

Creation of good policies and procedures is an art that can be helped with some
core advice. Policies are the backbone of how a business tells their employees
how to act and react, and ensures consistency and productivity. A great company
culture, a consistent vision and values, and compliance with… Continue Reading

LESSONS FROM THE CROWDSTRIKE INCIDENT

Yesterday, there was a world-wide incident that affected computers running
CrowdStrike Falcon, where there was a conflict between the vendor’s anti-malware
protection and the Windows sensor, resulting in a BSOD and unresponsive
computers. This is a major incident that was effectively the effective impact as
we were expecting from the… Continue Reading Lessons from the CrowdStrike
incident

SUPPLY CHAIN AND 3RD PARTY RISKS

Are you fully across your supply chain and 3rd party risks? Are you aware of all
the other people outside of your organisation who could have access to your
systems or data? There are many issues and threats that can occur when you lose
track of who is accessing your… Continue Reading Supply chain and 3rd Party

N-1 PATCHING STRATEGY

The technology industry is no different to many other industries and businesses
– in that it has jargon and terminology that may often need to be defined to be
understood. Within IT, the term “n-1” means that you are one version or release
behind the most recent. This is part… Continue Reading N-1 patching strategy

THE TRICKERY OF HACKERS

Hacking is a very asymetrical endeavour – the hacker can get big rewards for a
little effort. The hackers tickery will include ways to get a unwitting victim
to click on a link or to get past usual defences. As I have mentioned before,
the trickery of hackers only needs… Continue Reading The trickery of hackers

WHAT DOES DIVERSITY MEAN TO YOU?

On International Women’s Day, I am reminded of the need for diversity in the
workforce, and want to pose the question of what does diversity mean to you?
Diversity is not just the inclusion of other races, genders and backgrounds.
More than just a blind quota of non-white, non cisgender,… Continue Reading What
does diversity mean to you?

AI WILL STEAL OUR JOBS – REALLY?

A fearful catch-cry recently is that AI will steal our jobs – but is this really
true? Since Chat-GPT and other generative AI systems have become available,
there is a broad fear that it will start to take over and force people out of
their comfortably held jobs. It has… Continue Reading AI will steal our jobs –

PII IN AUSTRALIA AND PERSONAL INFORMATION

Terminology around privacy and security often will use the term “PII” – to refer
to “Personally Identifiable Information”. However, PII in Australia is not a
valid term – the definition by the OAIC is “personal information”, and it
differs from the US term (from NIST) and the legal obligations around… Continue

CYBERSECURITY AND DATA SOVEREIGNTY

Data Sovereignty with cybersecurity is a hot question that many organisations
consider to be one of their early considerations when selecting a service
provider for storing their data. The intention is that important data needs to
not be held in foreign datacentres, so that foreign governments cannot withhold
the data… Continue Reading Cybersecurity and Data Sovereignty

GET INFORMATION THE LOUIS THEROUX WAY

The English journalist Louis Theroux has a reputation for interviewing
“difficult” and unusual people and subcultures, and getting a large amount of
information and knowledge from people who otherwise do not open up to outsiders.
The techniques and patterns that he uses to get people to open up are methods…

CYBERSECURITY PLANNING

Cybersecurity is more than just firewalls and anti-virus, goes further than just
zero-trust approaches and cultural changes, and is beyond just policy and
compliance. Cybersecurity is not an ‘action’ or a ‘solution’ – it is an ongoing
activity that needs constant review and updating. Cybersecurity Planning will
vary for each… Continue Reading Cybersecurity planning

N-1 UPDATE STRATEGY

What is your strategy for patching and updates? Whilst it might be tempting to
just leave your systems on auto-update, the alternative to manually delay
updates to always be one behind the latest (also known as an N-1 update
strategy), may also be a problem. Updates and patching of software… Continue

CYBER INSURANCE MYTHS

With the ever-increasing levels and frequency of attacks and impact, businesses
of all sizes should consider specific cyber insurance. However there are some
Cyber Insurance myths that need to be dispelled. Myth #1 – My other insurance
will cover me Unless your other insurance specifically covers cyber events, you

FOCUS ON COMPLIANCE OR SECURITY?

I have posted a few articles about different security standards and frameworks,
such as PCI-DSS, The Essential 8, ISO27001, NIST and others – and in my
experience, there are some organisations that focus on compliance instead of
security. People desperately chase the dogma of maturity levels or complying
with every… Continue Reading Focus on Compliance or Security?

EDUCATE BOARDS IN CYBERSECURITY

As the world becomes more aware of cybersecurity risks and issues, company
boards need to become more aware of the issues that cybersecurity poses for
their businesses. However, it can be difficult for non-technical people to learn
the new terminologies and concepts. The question still remains on how we
educate… Continue Reading Educate Boards in Cybersecurity

DOES THE CISO NEED TO BECOME THE CSO?

A question that has been around my mind for a while is “does the CISO need to
become the CSO”? Is the responsibility of the Chief Information Security Officer
too limiting, and should they be the Chief Security Officer? The issue with a
CISO is that they often are limited… Continue Reading Does the CISO need to

OBVIOUS PCI-DSS BENEFITS

Last month, I wrote an article on the Essential 8. The article pointed out that
for most of the measures, they should be the absolute minimum measures that
organisations take with their systems. For those who work in the area of
security, most of the Essential 8 are common-sense and… Continue Reading Obvious

WHAT IS WRONG WITH THE ESSENTIAL 8?

The Australian Cyber Security Centre, working alongside the Australian Signals
Directorate (formerly Defence Signals Directorate) created a list of eight
essential mitigation strategies to act as a baseline for cybersecurity. These
are very much basic and essential measures, and they are an absolute minimum. As
a cybersecurity professional, these are… Continue Reading What is wrong with the

THINGS NOT TO DO IN SECURITY

Security is more than just activating firewalls and having complex passwords –
it is a culture and an approach. There are many things that we are told to do,
but also what is important is what not to do in security. Here is my list of the
top 5 things… Continue Reading Things not to do in security

CHALLENGING THE BALANCE BETWEEN SECURITY AND USABILITY

It is a well-known adage in cybersecurity that there is a balance between
usability and security – if you increase the security and control, you decrease
usability. Conversely, to make a system user-friendly and easy to use, it has to
be done at the cost of lowering security. This has… Continue Reading Challenging
