Threat monitoring definition
Threat monitoring is the process of monitoring and analyzing networks, systems, and data to identify threats and respond to them.
Threat monitoring works as the first line of defense in a system or network — it aims to eliminate or at least mitigate threats before they cause damage.

Examples of threat monitoring
- Network traffic analysis. Analyzes network traffic patterns and monitors network communications to identify malicious or unauthorized activities. This involves examining network flows, packet captures, and network behavior anomalies to detect signs of malware, intrusion attempts, or data exfiltration.
- Log monitoring. Monitors and analyzes logs generated by systems, applications, network devices, and security solutions to identify abnormal or suspicious activities.
- Intrusion Detection Systems (IDS). Deploy and manage intrusion detection systems that monitor network traffic and systems for known attack patterns or signatures.
- Security information and event management (SIEM). Collect and correlate security event data from various sources and provide a centralized view of security events.
- Vulnerability scanning. Conducts regular vulnerability scans to identify weaknesses or misconfigurations in systems, applications, or network infrastructure.
- Threat intelligence. Analyzes feeds and information from trusted sources to stay informed about emerging threats, attack techniques, and indicators of compromise.
