Intrusion Detection
Intrusion Detection is a cybersecurity concept and practice focused on monitoring network traffic or system activities to identify malicious behavior, policy violations, or security threats. It involves using specialized systems called Intrusion Detection Systems (IDS) that analyze data to detect suspicious patterns, such as unauthorized access attempts, malware activity, or anomalies. The goal is to provide early warning of potential attacks, enabling security teams to respond before significant damage occurs.
Developers should learn Intrusion Detection to enhance application and infrastructure security, especially when building or maintaining systems that handle sensitive data, such as financial services, healthcare, or e-commerce platforms. It is crucial for implementing defense-in-depth strategies, complying with security regulations (e.g., GDPR, HIPAA), and protecting against common threats like DDoS attacks, data breaches, and insider threats. Knowledge of IDS helps in designing secure architectures and integrating monitoring tools into DevOps pipelines.
