Network Security Monitoring
Network Security Monitoring (NSM) is a cybersecurity practice focused on the continuous collection, analysis, and escalation of network data to detect and respond to security threats. It involves monitoring network traffic, logs, and other data sources to identify malicious activity, intrusions, and policy violations. NSM provides real-time visibility into network security posture and enables proactive threat hunting and incident response.
Developers should learn NSM to build secure applications and infrastructure, as it helps identify vulnerabilities, detect attacks like DDoS or data exfiltration, and comply with security standards. It's crucial for roles in DevOps, cloud security, and system administration, especially when deploying services in production environments or handling sensitive data. NSM skills are essential for implementing defense-in-depth strategies and responding to security incidents effectively.
