An LLM (Large Language Model) is a type of artificial intelligence that uses vast datasets and deep learning techniques to understand, generate, and manipulate human language. These models are trained on massive amounts of language data to perform tasks such as text generation, translation, summarization, and answering questions. In the field of cybersecurity, LLMs assist with automation, anomaly detection, and enhanced security intelligence by analyzing and interpreting complex language data, detecting threats in logs, and providing insights into patterns.
