312-39 Exam Dumps : Certified SOC Analyst (CSA v2)

 When an incident is escalated to the Incident Response Team (IRT), the first step they undertake is Incident Analysis and Validation. This step is crucial to ensure that the incident is genuine and to understand its nature and scope. The IRT will analyze the information provided by the SOC analyst, validate the incident against known patterns or indicators of compromise, and gather additional information if necessary. This initial analysis helps in determining the severity of the incident and guides the subsequent steps in the incident response process.

A SOC Analyst would use Netstat Data tomonitor connections to insecure ports. Netstat, which stands for network statistics, is a command-line tool that displays incoming and outgoing network connections (both TCP and UDP), routing tables, and a number of network interface and network protocol statistics. It is available on various operating systems, including Windows, Linux, and Unix, and is used for finding problems in the network and to determine the amount of traffic on the network as a performance measurement.

The Setup event log is the most relevant Windows log for installation activity because it captures events related to software installation, servicing, and setup operations. For unauthorized application installs, the SOC needs timing, installer context, and evidence of package deployment or configuration changes driven by setup processes. The Setup log can contain MSI and update-related events, component installation records, and indications of system changes tied to installation workflows. The Security log is crucial for attribution (logons, privilege use, process creation if enabled), but it is not specifically focused on installer actions and may not capture full installation details unless advanced auditing is configured. The System log focuses on OS-level service and driver events (boot, service start/stop, hardware/driver issues) and may show related changes but is not the primary installation record. The Application log captures events written by applications themselves, which is inconsistent for installer tracing. In SOC practice, analysts often combine Setup log evidence with Security log context (who logged on, elevated rights, process lineage) and endpoint telemetry to identify the actor and technique, but the best single log for “when and how installs occurred” among these options is the Setup event log.
