Generative Artificial Intelligence (Generative AI) refers to a class of AI systems designed to create new content such as text, images, audio, or code by learning patterns from large datasets. Unlike traditional AI, which typically classifies or predicts based on input data, generative AI can produce original material that mimics the style and structure of its training data. In cybersecurity, generative AI can be used both defensively and offensively - for example, to generate realistic phishing emails or to simulate attack scenarios for training purposes. Its ability to automate content creation raises both opportunities and risks in the digital security landscape.
