Cases and events are two types of containers in Phantom. Cases are incidents with a known violation and a plan for correction, such as a malware infection, a phishing attack, or a data breach. Events are occurrences in the system that may require a response, such as an alert, a log entry, or an email. Cases and events can contain both high-level and low-level incident artifacts, such as IP addresses, URLs, files, or users. Cases do not contain a collection of containers, but rather a collection of artifacts, tasks, notes, and comments. Events are not necessarily potential threats, but rather indicators of potential threats. In the context of Splunk Phantom, cases and events serve different purposes. Cases are structured to manage and respond to incidents with known violations and typically have a plan for correction. They often involve a coordinated response and may include various artifacts, notes, tasks, and evidence that need to be managed collectively. Events, on the other hand, are occurrences or alerts within the system that may require a response. They can be considered as individual pieces of information or incidents that may be part of a larger case. Events are the building blocks that can be aggregated into cases if they are related and require a consolidated approach to incident response and investigation.
