This is the presentation that I delivered at InfoSec Netherlands. In the era of Digital Transformation, organisations are finding efficiencies with deploying systems and devices that are always connected - dubbed as the Internet of Things (IoT). If these 'things' are not carefully configured and maintained then they are a threat to your business. I discussed the common weaknesses that attackers exploit on IoT systems and the cybersecurity skills that you need to mitigate against them. The session also included a live attack to demonstrate how a device can become compromised.

Protecting your Organisation from the Internet of Evil Things

E-commerce has presented a new way of doing transactions all over the world using internet. The success of ecommerce depends greatly on how its information technology is used. Over the years the rate at which ecommerce sensitive information is sent over the internet and network has increased drastically. It is for this reason that every company wants to ensure that its ecommerce information is secured. There is need for ecommerce information transmitted via the internet and computer networks to be protected. There is substantial growth in the areas of credit card fraud and identity theft because the internet is a public network with thousands of millions of users. Amongst users are crackers or hackers that carry out the credit card fraud and identity theft in numerous ways facilitated by poor internet security; a concern regarding the exchange of money securely and conveniently over the internet increases. The criticality, danger, and higher priority importance of any e-commerce money transfer makes it a hot area of research interest in modern computer science and informatics. E-commerce industry is slowly addressing security issues on their internal networks but security protection for the consumers is still in its infancy, thus posing a barrier to the development of e-commerce. There is a growing need for technological solutions to globally secure ecommerce transaction information by using appropriate data security technology. The technology solution proposed for solving this security problem is the RSA cryptosystem. This research paper focuses on securing ecommerce information sent through the computer network and internet using RSA cryptography. It elucidates the implementation of RSA algorithm and shows that ecommerce security powered with RSA cryptography is very important in ecommerce transaction. While many attacks exist, the system has proven to be very secure

Internet (or Cyber) Governance has a long way to go and is presently fraught with confusion - this being a global phenomenon. Then there is the Internet of Things coming up at top speed which means that we have to face up to the risks that come with the convenience ! A solution for governance and some insight into the IoT risks were presented at the Defcon-OWASP Conference in Lucknow (India) on February 22, 2015

The ability for everyday devices to connect with each other and with people is a hot topic. The Nigerian Communications Commission identified a need for the Nigerian legal system to be aware of present and future possibilities, grey areas and learnings from other countries that have taken proactive steps to prepare for this inevitable future. Learnings from the EU, USA, China etc are considered. It is comforting to know that no country claims to have its legislation ahead of the tech innovations curve, but the catchup game needs to be at a pace that dragnets the present effectively and constantly repositions for the unknown future. Regulation should also be smart. Rather than get bogged down regulating aluminium weight for car use, fuel grades for combustion, rather regulate speed (protect lives) and drive regulation by principles that outlive wherever tech wants to go next. The session was eye-opening for a good number of the aged and candid judges, but it was gladdening to see the mindset: mobile tech is not "that thing", it has to be used, understood and admitted as evidence. The nerds and more tech savvy should help these 'learned ones' to better embrace tech and help them do their work better for joint good! Attendee/delegate feedback was candid and NCC hopes to build on this in the coming years.

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
