LLM Applications Across Cybersecurity
LLMs are transforming cybersecurity by enabling intelligent, adaptive, and automated approaches to threat detection, vulnerability assessment, and incident response. With advanced language understanding and contextual reasoning, LLMs surpass traditional methods in tackling challenges across domains such as Network Security (web fuzzing, intrusion detection), Software and System Security (vulnerability detection, bug repair, malware detection), Blockchain Security (smart contract auditing, anomaly detection), Cloud Security (misconfiguration detection, data leakage monitoring), Hardware Security (vulnerability detection, repair), and IoT Security (firmware vulnerability detection, behavioral anomaly detection).
