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

In PostgreSQL, the configuration parameter that enables writing logs to files via the logging collector process islog_collector. When enabled, PostgreSQL can collect stderr output from backend processes and route it into log files, which is foundational for centralized log shipping and retention. From a SOC standpoint, turning on log collection is necessary but not sufficient: you typically also need to configure what gets logged (authentication failures, statement duration thresholds for slow queries, and error verbosity), define log line prefixes for consistent parsing, and set rotation/retention to meet operational and compliance needs. However, the question specifically asks which parameter should be enabled to ensure PostgreSQL captures and stores logs, and log_collector is the correct parameter name and casing. The other options include incorrect naming or formatting. Once enabled, the SOC team can forward PostgreSQL logs to the SIEM to correlate database activity with identity, endpoint, and network signals—critical for detecting brute force attempts, suspicious administrative actions, and anomalous query behavior.

An output-driven SIEM deployment builds capability by starting with a narrowly defined, high-value detection outcome and then expanding once success is proven. The primary advantage is that it supports iterative growth into broader and more complex use cases with confidence. Each validated use case forces disciplined work on prerequisites: correct data onboarding, parsing, field normalization, baseline understanding, and tuning to reduce false positives. That foundation enables more advanced scenarios that require richer correlation (for example, linking identity events, network telemetry, endpoint behavior, and application logs) and often cover longer timelines or more complex workflows, such as supply chain disruption detection. Option A is not an advantage; collecting logs from non-critical systems may or may not be required depending on use cases. Option C is unrealistic because response speed depends on staffing and workflows, not only SIEM deployment strategy. Option D implies active prevention, which is not the SIEM’s core role (it can trigger automation, but blocking is not automatic by default). Therefore, the best advantage among the given options is enabling creation and expansion to more complex use cases with wider scope.

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.
