Deepfakes: uncovering the security risks

There's a lot being said (and written) about deepfakes.

And there is no doubt that they can now be very convincing, to the point where they can deceive the human eye.

But are deepfakes just a bit of fun, or do they pose real security risks? Do the dangers lie in manipulating public opinion through fake news, or can deepfakes be used to breach security systems.

Our guest, Dr Andrew Newell, academic researcher and chief scientific officer at iProov, argues that both are happening. Security teams need to take steps to block deepfakes from compromising identity systems, but we all need to guard against their wider influence.

SaaS and security: shared responsibility, or hidden risks?

Software as a service, or SaaS, has been a huge success. There are now some 30 thousand SaaS applications on the market worldwide. These cover everything from niche requirements to running entire businesses.

The SaaS revolution has certainly brought benefits to businesses.

But are SaaS applications secure and robust enough? Supporters of SaaS argue that their applications are actually safer and more resilient than locally-run IT.

However, Cloud vendors, including SaaS companies, rely on the shared responsibility model. In simple terms, they look after the infrastructure, but the customer is responsible for their data.

This can leave organisations with real problems, if their data is inaccessible, or even deleted.

This could be down to human error, malicious actions, such as a ransomware attack, or even a SaaS provider failure.

Our guest today is Simon Taylor, Founder and CEO of HYCU. He believes that SaaS users need to take more control of their data, even when it's in a SaaS application.

Investing in cyber: should we follow the money?

Europe's cybersecurity industry is worth some $50bn and is growing at 10% a year.

It's also pretty fragmented – at least when it comes to vendors. Europe -- even more so than the US -- is now ready for market consolidation.

Some of that is being driven by acquisitions by the large technology firms, as they look to broaden their cybersecurity offerings.

But firms, and their investors, are looking for scale.

And CISOs are looking for simplicity and greater security. Could vendor consolidation achieve this? And what is the role of cybersecurity "platforms" as the industry changes shape?

Our guest is Mark Smith, of advisory firm Houlihan Lokey.

Cyber escape rooms - and experiential learning

Conventional security training leaves a lot to be desired.

So what can CISOs do, to deliver training and security awareness in a way that is effective, and engaging?

Over the last few episodes we've discussed both the psychology, and human factors, around cybersecurity. To finish the series, in this programme we will look at experiential learning, or learning by doing.

Our guest is Amy Stokes-Waters. She delivers exactly that, by running escape rooms for organisations who want to improve security awareness, but want to move away from slide-heavy courses, and checkbox compliance. She's also written a paper on experiential learning in cybersecurity.

But does it work? She discusses cyber escape rooms, learning theory, and the pros and cons of measurement with editor Stephen Pritchard.

Human Risk Management: tackling cybersecurity's weak spot

How do we manage the risks posed by human behaviour?

In this, the second of our short series exploring the links between human behaviour and security, we look at the emerging field of human risk management.

The statistics are quite frightening: 90 per cent of security breaches involve human error or social engineering.

But how do we, at a business level, categorise those risks? If we don’t understand the risks, we can’t reduce them.

A better understanding of where the risks are – and which behaviours are risky – makes it easier to design counter measures, such as training.

Our guests this week are Lev Lesokhin and Charlotte Jupp, of OutThink – an firm that’s pioneering human risk management.

We discuss what human risk management involves, and how security teams can make use of it, without crossing privacy boundaries.

 

Mind games: the psychology of cybersecurity

How important is human behaviour in cybersecurity? How well do we know our people, and do we understand the risks posed by individuals' actions?

Research suggests that the overwhelming majority of cyber breaches start with human error or poor practice. But despite investments in security training and security awareness, we still make mistakes.

Over the next three episodes, we will examine some of the human factors around cybersecurity, including human risk management, and how we change behaviour.

We'll start the series by looking at the psychology of cybersecurity, as well as how to measure change.

Our guest is Dr Thea Mannix, a neuroscientist and head of research at Praxis Security Labs

AI: chatbots, cut and paste, and data leaks

Our guest for this episode is Tim Freestone, of Kiteworks. He’s a long-standing expert in data protection and data privacy. And he's been following the growth of AI, and what it means for data privacy, security and confidentiality.

Even data specialists have been surprised by the rapid take up of generative AI and its benefits. But do we have the measure in place to guard against the potential security risks it brings?

It is not just malicious hackers who make AI tools such as chatbots a risk. Even something as simple as pasting information into a generative AI tool can cause problems. And he argues that we need to apply security's zero trust approach to AI too.

IT, OT, and CNI: a hidden threat?

Any advanced economy relies on the smooth running of its infrastucture.

And whether it’s transport, logistics, healthcare, the banking system, manufacturing – even food production – industrial and operational systems are what keeps it all running.

Those systems are now being targeted by malicious actors. Both state-sponsored and criminal groups are looking closely at operational technology and industrial systems.

Recent research suggests that many, if not most, of the groups attacking critical national infrastructure are linked to national intelligence agencies. And that raises some difficult questions about how both businesses, and their governments, should respond.

Our guest is Mark Magpie Graham, technical director for threat intelligence at Dragos, who carried out the research.

Ransomware: can transparency bring security?

It's hard to put an exact figure on ransomware attacks. All the available research shows incidents continue to grow year on year, and that the vast majority of cyber incidents are now ransomware or other extortion attacks.

But could more transparency and information sharing help defend against ransomware?

If more organisations disclosed attacks, we would have a clearer picture of the problem and be able to respond more quicky to new techniques or attack vectors.

That's the argument put forward by this week's guest.

Sabeen Malik is vice president of global government affairs and public policy at Rapid7. She has put together a ransomware disclosure framework, based around the "3 Cs" of capabilities, context, and collective action.

She tells Stephen Pritchard how it works, and why it could help.

Cyber war: new lessons from history?

The idea of cyber war is not new; researchers first suggested the concept 30 years ago.

Since then, there's been a debate on what cyber war means and what can be done to prevent it.

Some experts even suggest cyber war is already happening, even if it is mostly in the shadows.

For Peter Kestner, the rise of cyber attacks and an increasingly volatile geopolitical situation were just two of the reasons to examine cyber warfare in more detail.

Peter is both a keen student of history, and a cybersecurity professional with over 25 years' experience in consulting in the sector.

He decided to combine the two interests, and the result is his new book, "The Art of Cyber Warfare".

Peter believes that by looking into conflicts in the past, we can learn valuable lessons about how warfare, and especially cyber warfare, might develop. But history can also teach us how to improve our defences, against adversaries who are as comfortable attacking civilian as government or military targets.
