Custom Managed Installers for Windows Defender Application Control

Organisations are compelled to implement Application Control solutions to meet security regulations for both internal organisational policy as well as guidance from bodies such as NCSC, ACSC or NIST.

Often the decision to implement these security controls are made by people who do not understand the impact on productivity for advanced technology workers such as developers and engineers, creating the need for complicated configurations and solutions to meet the regulatory obligation and needs of the workforce.

This talk will provide a meaningful compromise to this problem using Managed Installers in Windows Defender Application Control. Attend this session to learn how to create flexibility while still maintaining control of your environment.

There will be demonstrations of the solution including example configurations and installations using a popular package managers such as brew or chocolatey enabling professionals productivity, yet reducing the risk of ransomware or other malicious software being able to have free reign on the system.

What I learnt about automating security

By 2025 there will be an estimated 3.5 million cyber security jobs open globally. This is up from 1 million in 2014. This is a problem that will impact most organisations globally as they struggle to find qualified talent to manage their daily cyber security operations as well as engage in projects and product development.

Cyber Security can be often delegated as 'someone else's problem' much like you don't think it will be your house broken into or your belongings being stolen, sadly this being a priority often too late, usually after an incident occurs and remediation after the activity is needed.

To combat this, I wanted to investigate what an organisation can do to automate as many security functions as possible to supplement staff, not replace and lighten the workload of already beleaguered security teams. This session will describe what I have found, what is working, and where the short falls are. The session will cover as many broad aspects as possible of an organisations IT operations and projects life cycles including systems and application development. Building and managing infrastructure as well as the humans that rely on these systems.

This session won't be a deep dive in any one area, it will be a bird's eye view of end-to-end cyber security for a business.

How to go from NO to GO! Developers working with Security.

Developers care about writing code. They want to solve problems, efficiently, and ship products. They use methodologies like Agile and Scrum, full of sprints to produce features and releases; fast. Security on the other hand, want safe and secure code, even if it slows delivery.

Co-operation between Developers and Operations has been "solved" with DevOps. Security came along and tried to shoehorn in the middle with "DevSecOps", but has it worked? Is it enough? Are Developers and security working together or are they beaten into submission of compliance with company security policy and governance controls.

This talk will look at practical ways that Developers and Security Teams can work together to secure code and product, reduce risk in the organisation, and change the perception of Security as being the the handbrake, to a partner safely shipping code; fast.

From Tech Confidence to Cyber Victim: The Irony of Pig Butchering Scams

"From Tech Confidence to Cyber Victim" offers a compelling look into the world of 'pig butchering' scams, where the very strengths that define IT professionals can become their greatest vulnerabilities. This talk explores the ironic twist where high confidence in technological expertise leads even the most seasoned IT experts into the traps of sophisticated online fraud.

We'll examine how the unique skills and attributes of IT professionals—such as a deep understanding of complex systems, problem-solving abilities, and routine exposure to cyber risks—can paradoxically make them more susceptible to these emotionally driven scams. Delving into real-life examples, we illustrate how scammers artfully blend technical jargon with psychological manipulation, exploiting the blind spots created by tech confidence.

This session is designed to bridge the gap between technical know-how and the often-overlooked human element of cybersecurity. Attendees will learn about the subtle intricacies of 'pig butchering' scams, why their professional expertise might not be the complete armour they thought it was, and how to develop a more holistic approach to digital safety and scepticism.

Join us for an enlightening journey from the peaks of tech confidence to the unforeseen valleys of cyber victimhood and arm yourself with the knowledge to defend against the ironies of modern cyber threats.

Securing Cloud API Access

All public cloud providers have multiple interfaces for managing your infrastructure and applications hosted within. If you were to follow a journey of cloud maturity you start with click-ops authenticated via username and password, and progress towards automation leveraging programmatic methods using API.

A recent survey showed that 75% of participants found it daunting to leverage Cloud API due to getting credentialed access. Starting to learn this can be daunting even if you are a seasoned IT professional. Where do you start? How do you authenticate? How do you secure your solution using best practice?

Attend this session to get a kick start on leveraging APIs in public cloud, ways to get API access, how to secure this access, and resources you can take away to continue your learning journey.

Developers, the new targets in the cyber battleground.

Developers are the driving force behind value creation in today's digital age. They have the superpower to turn code into revenue-generating products that can scale to unicorn proportions. However, with great power comes great responsibility. Developers are granted extensive permissions to do their work, but these same permissions can also pose a security risk if they fall into the wrong hands. That's why it's crucial to implement security measures that protect your organization without hindering your developers' productivity.

Join us for a talk on practical tips for securing your developers. We'll discuss tools, techniques, and procedures for securing both human and automated workflows. You'll learn how to:

* Identify and mitigate common security risks in the developer environment
* Implement security controls that balance protection and productivity
* Empower developers to work securely and efficiently

Don't let security be an afterthought. Join us and learn how to build a culture of security that starts with the developer.

Leveraging Generative AI for Cybersecurity. Attack, Defence and Ethics.

As cyber threats become more sophisticated, it's crucial to leverage advanced technologies to defend against them. One technology that has gained significant attention in recently is generative AI such as the Open AI GPT based models. In this session, we will explore how they could be used to carry out, and defend against, cyber-attacks.

We will discuss how generative AI can be leveraged to assist with targeted phishing attacks. Using a GPT based AI, an attacker can quickly create convincing phishing emails that are more likely to succeed. Further to this GPT based AI can guide the attacker with building the necessary infrastructure to host the whole attack chain. We will demonstrate this potential and discuss the implications of these attacks for cybersecurity.

Next, we explore how generative AI can assist defence against cyber threats. This technology can detect and advise on threats in real-time, allowing organizations to quickly identify and neutralize attacks to limit damage. We will provide examples of GPT based AI is used for defence, such as Microsoft Security Co-Pilot, and demonstrate this technology for organizations looking to improve their cybersecurity posture.
Lastly, we discuss the ethical implications of using generative AI for cybersecurity. As with any emerging technology, there are potential risks and drawbacks to consider, including issues related to privacy, bias, and accountability. We explore these issues and discuss how organizations can balance the benefits of this modern technology with the potential risks.

This will be the first conference delivery for this session but will be delivered at a local security meetup before the conference.
