質問 # 103
David is a SOC analyst in Karen Tech. One day an attack is initiated by the intruders but David was not able to find any suspicious events.
This type of incident is categorized into?
正解：A
解説：
A false negative incident in the context of a Security Operations Center (SOC) is when an actual attack or intrusion occurs, but the SOC analyst fails to detect any suspicious events or indicators of compromise. This means that the security measures in place did not work as intended, and the attack went unnoticed.
In David's case, since an attack was initiated and he was not able to find any suspicious events, it is categorized as a false negative incident. This is a critical type of incident because it indicates a failure in the detection capabilities of the SOC, potentially allowing the intruder to cause harm without being detected.
References: The categorization of incidents is a fundamental part of the SOC Analyst's role, as outlined in the EC-Council's Certified SOC Analyst (CSA) training and certification program. The program covers the different types of incidents that can be encountered in a SOC, including true positives, false positives, true negatives, and false negatives, and how to identify and respond to each12345.
質問 # 104
A SOC analyst detects multiple instances of powershell.exe being launched with the -ExecutionPolicy Bypass and -NoProfile arguments on a domain controller. The parent process is winrm.exe, and the activity occurs during non-business hours. What should be the analyst's primary focus?
正解：B
解説：
The highest-signal next step is to scope and confirm the suspicious execution pattern by identifying related process creation events. Event ID 4688 records process creation in Windows Security logs when auditing is enabled, and it can capture command-line details that confirm the use of -ExecutionPolicy Bypass and - NoProfile, as well as parent/child relationships. Since the activity is on a domain controller and the parent is winrm.exe (remote management), the SOC must quickly determine whether this is isolated or part of a broader remote execution campaign. Searching for similar 4688 events over a relevant window (such as the last 24 hours) helps identify frequency, affected accounts, and whether the same command line or script path appears across hosts. Event ID 4625 (failed logon) can provide context for brute force attempts, but it does not directly validate or scope the suspicious PowerShell executions already observed. Event ID 7045 (new service installation) is important if there are signs of service-based persistence, but it is a different hypothesis. Event ID 5145 is about network share access and can be useful for lateral movement, but the immediate priority is to scope execution behavior. Therefore, focusing on 4688 process creation for similar PowerShell executions is the best primary step.
質問 # 105
An organization with a complex IT infrastructure is planning to implement a SIEM solution to improve its threat detection and response capabilities. Due to the scale and complexity of its systems, the organization opts for a phased deployment approach to ensure a smooth implementation and reduce potential risks. Which of the following should be the first phase in their SIEM deployment strategy?
正解：D
解説：
The first phase should establish reliable log ingestion and storage-log management-before attempting advanced detection content or automation. A SIEM is only as effective as the data it receives. In a complex environment, initial success depends on building a stable pipeline: collecting logs from priority sources, normalizing timestamps, ensuring consistent parsing, defining retention, and validating data quality (completeness, latency, duplication, and integrity). Without this foundation, analytics will produce blind spots, false positives, and missed detections, and automation may take disruptive actions based on incomplete data. UEBA and security analytics are valuable but require sufficient historical, high-quality telemetry to build baselines and correlations. Similarly, incident response automation should come after the organization has validated detections, tuning, and operational workflows; otherwise, playbooks may amplify errors at scale. A phased approach typically starts with identifying key data sources (identity, endpoint, network, cloud), onboarding them into log management, confirming visibility and schema consistency, and only then layering detection rules, correlations, and response workflows. Therefore, setting up log management first is the correct starting phase for a low-risk, high-success SIEM deployment.
