- 3. 3 www.smartlearninguk.com3 www.smartlearninguk.com What is Artificial Intelligence? AI broadly refers to the ability of machines to "think" like humans and perform tasks considered "smart," without explicitly being programmed to do so. ML is a subset of AI. ML algorithms build a mathematical model based on training data, and they leverage the model to make predictions when new data is provided Source: pwc Wale Omolere Role of Ai in cyber security

- 7. 7 www.smartlearninguk.com7 www.smartlearninguk.com Supervised learning is when a model learns from a labeled dataset with guidance. And, Unsupervised learning is where the machine is given training based on unlabeled data without any guidance. Whereas Reinforcement learning is when a machine or an agent interacts with its environment, performs actions, and learns by a trial-and-error method. .

- 12. 12 www.smartlearninguk.com12 www.smartlearninguk.com 02 | Manual Manual threat hunting—can be expensive and time-consuming, resulting in more unnoticed attacks. 04 | Hackers Hackers often hide and change their IP addresses—hackers use different programs like Virtual Private Networks (VPN), Proxy servers, Tor browsers, and more. These programs help hackers stay anonymous and undetected. 01 | Defence Paradigm Defence paradigm based on previous knowledge of attacks— inefficient against zero-day and variations 03 | Reactive Reactive nature of cybersecurity— companies can resolve problems only after they have already happened. Predicting threats before they occur is a great challenge for security experts. Key flaws of Cyber Security Wale Omolere Role of Ai in cyber security
- 13. 13 www.smartlearninguk.com13 www.smartlearninguk.com The next generation of cyber security products are increasingly incorporating Artificial Intelligence (AI) and Machine Learning (ML) technologies. By training AI software on large datasets of cyber security, network, and even physical information, cyber security solutions providers aim to detect and block abnormal behaviour. There are different approaches to using AI for cyber security, and it is important first to determine which is appropriate for the organization. Some software applications analyse raw network data to spot an irregularity, while others focus on user/asset/entity behaviour to detect patterns that deviate from normal. The types of data streams, how they are collected, and the level of effort needed by analysts all vary by approach.
