Security monitoring refers to the automated and centralized process of detecting and analyzing indications of potential security threats so that appropriate action can then be taken against these cyber threats.
Unfortunately, traditional blocking measures (e.g. a firewall) and an adequate SIEM (Security Incident and Event Management System) are no longer sufficient to protect against hacker attacks. Security Monitoring offers you permanent monitoring. Certain software (e.g. Splunk) visually correlates malicious activity in real time and prioritizes real risks that you can take immediate action.
