Which type of analysis focuses on collecting data from a live system?

The type of analysis that emphasizes collecting data from a live system is volatile analysis. This method is particularly critical in digital forensics because it deals with data that is present in the system's memory at a given moment, which typically includes processes, network connections, and temporary files that may disappear once the system is powered down or rebooted.

Volatile analysis is essential in cybersecurity investigations as it allows forensic investigators to capture a snapshot of what is actively running on the computer, providing insights that can be pivotal for incident response and understanding the nature of an attack or compromise. Given the transient nature of this data, capturing volatile information while the system is still live is crucial for assessing potential threats or vulnerabilities effectively.

The other methods mentioned, such as static analysis, post-mortem analysis, and live data analysis, serve different purposes within the forensic investigation spectrum and do not specifically focus on the action of gathering data from a live system in the same critical way that volatile analysis does. Static analysis generally refers to examining data that isn't in a volatile state, post-mortem analysis deals with data that has already been preserved from a dead system, and live data analysis can sometimes overlap with volatile analysis but may focus more broadly on ongoing examinations of a system rather than a
