Key Characteristics
A Digital Immune System is a comprehensive approach to building resilient and self-protecting digital systems that can detect, adapt to, and recover from various types of threats and disruptions. This concept draws inspiration from biological immune systems, applying similar principles of detection, response, and memory to digital environments.
Digital Immune Systems integrate multiple technologies and practices including artificial intelligence, machine learning, automation, and advanced monitoring to create self-healing and self-protecting digital ecosystems. These systems continuously monitor for anomalies, threats, and performance issues, automatically responding to maintain system health and security.
