ChatGPT and other GAN technologies are dominating the news, but can you tell what’s hype and what’s not? How do these AI tools work? Are there security applications or concerns? How difficult is it to use these tools for red/blue/purple team accelerators? In our Featured Keynote, SANS Fellow David Hoelzer will discuss potential risks that advanced AI poses to cybersecurity, and what steps are being taken to address these challenges. He will also demonstrate and explore the ways in which AI can be used to improve cybersecurity and protect against cyber threats. If you want to be in the know on AI, join David for this comprehensive overview and its potential impact on cybersecurity and society.
ChatGPT, GPT-4, Llama 2, Bard, Minerva, Megatron, Claude, Chinchilla... What exactly are these "Large Language Models" that are in the news? What are they really good for? How do they work? What are the risks when we incorporate these into our business process? This 90 minute presentation and tutorial will explain how these models work, what transformers are, how embeddings work, and how to build a question answering AI... the easy way and the hard way.. in addition to discussing the very real risks that come into play when we try to integrate these systems into a business process!
Corporations with a mature security organization should be doing threat hunting. Is this as simple as searching for known IOCs in our environment? While this is an important task, this is not threat hunting. Threat hunting is looking for unknown bad, which implies that there are no IOCs! Can AI and machine learning help us to do effective threat hunting? Are there real-world applications of these technologies that are useful today? Yes! This one hour webcast will discuss a variety of practical applications of machine learning and AI that organizations can implement today to augment our threat hunting capability.
