SIEM could tell when the breach occurred in firewall AND in network management solution

A SIEM (Security Information and Event Management) system is designed to collect, analyze, and correlate log and event data from various devices and applications across the network. In the context of the given scenario, a SIEM system would be the most appropriate tool to identify when the breach occurred through each device (firewall and network management solution). In contrast, SIEM correlation dashboards can aggregate and correlate logs from multiple sources, allowing security analysts to piece together the timeline of events and detect anomalies and potential breaches more effectively. This makes it the most appropriate option for identifying when the breach occurred through each device in the given scenario, according to the CompTIA Security+ SY0-601 exam objectives.

SIEM correlation dashboards collect and analyze security event logs from various devices and systems within an organization's network, including firewalls and network management solutions. By aggregating and correlating these logs, the SIEM can identify patterns and anomalies that may indicate a security breach. This can help in pinpointing the timeframe in which the breach occurred through each device.

SIEM (security information and event management) dashboards are the windows into the SIEM datastore, a collection of information that can tell you where attacks are occurring and provide a trail of breadcrumbs to show how the attacker got into the network and moved to where they are now. SIEM systems act as the information repository for information surrounding potential and actual intrusions. During an investigation, the SIEM system can provide a host of information concerning a user, what they have done, and so on. The fundamental purpose of a SIEM system is to provide alerts and relevant information to incident response teams that are investigating incidents. If something happens that initiates an investigation, and the SIEM system has no relevant information, then this suggests that the SIEM and its component elements need better tuning to provide meaningful surveillance of the system for potential problems.
