An Introduction to Security Monitoring

Security monitoring is the continuous process of observing and analyzing an organization's IT environment to detect and respond to cybersecurity threats. It involves collecting and evaluating data from various sources within a network, such as system logs, network traffic, and application activities, to identify suspicious patterns or unauthorized system changes. The core idea is to gain real-time (or near real-time) visibility into the security posture of an organization, allowing for swift action when potential security incidents are identified. This proactive stance is crucial in today's digital landscape, where cyber threats are constantly evolving and becoming increasingly sophisticated.
