What type of tooling is typically used for analyzing network security events?

Intrusion Detection Systems (IDS) are specifically designed for the purpose of monitoring network traffic for any suspicious activity or violations of security policies. They analyze events in real-time or log network traffic for later examination, enabling organizations to detect potential security incidents, such as unauthorized access or anomaly detection. By identifying patterns that may signify an intrusion, IDS provide critical information that security teams can use to respond to threats effectively.

In contrast, firewalls play a preventive role by filtering incoming and outgoing traffic based on predetermined security rules, but they do not analyze events after they occur. Content Delivery Networks primarily optimize the delivery of content rather than providing security event analysis. Access Control Systems focus on controlling who has permission to enter or use resources within a network, rather than monitoring security events. Thus, IDS stands out as the key tool specifically tailored for analyzing network security events.
