EC-COUNCIL Certified SOC Analyst (CSA) - 312-39 Exam Practice Test

At a large healthcare organization, the Security Operations Center (SOC) detects a surge of failed login attempts on employee accounts, indicating a possible brute-force attack. To contain the threat, the team quickly takes action to prevent unauthorized access. However, they also need to implement a security measure that strengthens account protection beyond just stopping the current attack, reducing the risk of similar incidents in the future. During the Containment Phase, which action would best enhance long-term account security against brute-force attacks?

At 10:30 AM, during routine monitoring, Tier 1 SOC analyst Jennifer detects unusual network traffic and confirms an active LockBit ransomware infection targeting systems in the finance department. She escalates to the SOC lead, Sarah, who activates the Incident Response Team (IRT) and instructs the network team to isolate the finance department's VLAN to prevent further spread across the network. Which phase of the Incident Response process is currently being implemented?

The threat intelligence, which will help you, understand adversary intent and make informed decision to ensure appropriate security in alignment with risk.
What kind of threat intelligence described above?

Which of the following attack inundates DHCP servers with fake DHCP requests toexhaust all available IP addresses?

Which of the following technique involves scanning the headers of IP packets leaving a network to make sure thatthe unauthorized or malicious traffic never leaves the internal network?

Identify the event severity level in Windows logs for the events that are not necessarily significant, but may indicate a possible future problem.

A threat hunter analyzing an infected endpoint finds that malicious processes keep reappearing even after termination, making traditional remediation ineffective. The user reports slowdowns, abnormal pop-ups, and unauthorized application launches. Deeper inspection reveals multiple scheduled tasks executing unknown scripts at intervals, along with suspicious registry modifications enabling automatic execution on startup. The endpoint makes intermittent encrypted outbound connections to an unclassified external server. The organization also observed multiple failed privileged logins from the same subnet. Which signs should the threat hunter look for to confirm and mitigate the threat?

If the SIEM generates the following four alerts at the same time:
I.Firewall blocking traffic fromgetting into the network alerts
II.SQL injection attempt alerts
III.Data deletion attempt alerts
IV.Brute-force attempt alerts
Which alert should be given least priority as per effective alert triaging?

Emmanuel is working as a SOC analyst in a company named Tobey Tech. The manager of Tobey Tech recently recruited an Incident Response Team (IRT) for his company. In the process of collaboration with the IRT, Emmanueljust escalated an incident to the IRT.
What is the first step that the IRT will do to the incident escalated by Emmanuel?

A multinational cybersecurity firm wants to enhance its threat intelligence capabilities by integrating real-time threat feeds into Microsoft Sentinel. These feeds include malicious IPs, domains, file hashes, and attack patterns. The firm requires a standardized protocol that allows automated threat intelligence sharing so Sentinel continuously receives updated indicators from external sources in a structured format. Which Microsoft Sentinel data connector should be implemented to integrate threat intelligence feeds using an industry-standard protocol?

Which of the log storage method arranges event logs in the form of a circularbuffer?

A large financial institution has identified a sophisticated phishing campaign targeting employees, resulting in unauthorized access to sensitive customer data. The organization already uses a SIEM for log aggregation and alerting, alongside an EDR solution for endpoint visibility. Additionally, they have access to XDR for broader threat detection and XSOAR for security orchestration and automation. As a SOC analyst, you've been asked to recommend an integration strategy to improve real-time threat correlation, streamline incident response workflows, and maximize the use of existing tools. Which integration would meet these goals?

TechInnovate receives an alert about a newly discovered zero-day vulnerability in a widely used web application framework that is being actively exploited. No official patch is available. The SOC must monitor adversary tactics, identify indicators of compromise (IoCs), and proactively adjust controls to detect, track, and mitigate the threat. Which SOC technology is crucial for real-time visibility into evolving threat intelligence and enabling proactive mitigation?

A large financial institution receives thousands of security logs daily from firewalls, IDS systems, and user authentication platforms. The SOC uses an AI-driven SIEM system with Natural Language Processing (NLP) capabilities to streamline threat detection. This enables faster response times, reduces manual rule creation, and helps detect advanced threats that traditional systems might overlook. Which option best illustrates the advantage of NLP in SIEM?
