Security Orchestration, Automation, and Response (SOAR)solutions allow organizations tointegrate security tools, automate response actions, and aggregate threat intelligence. This matches the organization ' s goal ofthreat detection, real-time analysis, and data aggregation​.

Option A (DLP - Data Loss Prevention)is focused ondata securityrather than threat aggregation and response automation.

Option B (Heuristics)is amethod for threat detection, not aplatformfor security automation.

Option D (NAC - Network Access Control)manages device access rather than handling security automation.

Thus,C (SOAR) is the correct answer, asit automates threat detection, intelligence integration, and real-time response​.

This is because scanning without admin privileges can limit the scope and accuracy of the vulnerability scan, and potentially miss some critical vulnerabilities that require higher privileges to detect. According to the OWASP Vulnerability Management Guide1, “scanning without administrative privileges will result in a large number of false negatives and an incomplete scan”. Therefore, the analyst should recommend addressing this issue to ensure potential vulnerabilities are identified.

Performing a tabletop drill based on previously identified incident scenarios is the best way to test the changes to the BC and DR plans without any impact to the business, as it is a low-cost and low-risk method of exercising the plans and identifying any gaps or issues. A tabletop drill is a type of BC/DR exercise that involves gathering key personnel from different departments and roles and discussing how they would respond to a hypothetical incident scenario. A tabletop drill does not involve any actual simulation or disruption of the systems or processes, but rather relies on verbal communication and documentation review. A tabletop drill can help to ensure that everyone is familiar with the BC/DR plans, that the plans reflect the current state of the organization, and that the plans are consistent and coordinated across different functions. The other options are not as suitable as performing a tabletop drill, as they involve more cost, risk, or impact to the business. Simulating an incident by shutting down power to the primary data center is a type of BC/DR exercise that involves creating an actual disruption or outage of a critical system or process, and observing how the organization responds and recovers. This type of exercise can provide a realistic assessment of the BC/DR capabilities, but it can also cause significant impact to the business operations, customers, and reputation. Migrating active workloads from the primary data center to the secondary location is a type of BC/DR exercise that involves switching over from one system or site to another, and verifying that the backup system or site can support the normal operations. This type of exercise can help to validate the functionality and performance of the backup system or site, but it can also incur high costs, complexity, and potential errors or failures. Comparing the current plan to lessons learned from previous incidents is a type of BC/DR activity that involves reviewing past experiences and outcomes, and identifying best practices or improvement opportunities. This activity can help to update and refine the BC/DR plans, but it does not test or validate them in a simulated or actual scenario

The NTP configuration on each system should be checked first, as it is essential for ensuring accurate and consistent time stamps across different systems. NTP is the Network Time Protocol, which is used to synchronize the clocks of computers over a network. NTP uses a hierarchical system of time sources, where each level is assigned a stratum number. The most accurate time sources, such as atomic clocks or GPS receivers, are at stratum 0, and the devices that synchronize with them are at stratum 1, and so on. NTP clients can query multiple NTP servers and use algorithms to select the best time source and adjust their clocks accordingly1. If the NTP configuration is not consistent or correct on each system, the time stamps of the logs and events may differ, making it difficult to correlate incidents across different systems. This can affect the security analysis and correlation of events, as well as the compliance and auditing of the network23.

Command and control (C2) is a phase of the Cyber Kill Chain that involves the adversary attempting to establish communication with a successfully exploited target. C2 enables the adversary to remotely control or manipulate the target system or network using various methods, such as malware callbacks, backdoors, botnets, or covert channels. C2 allows the adversary to maintain persistence, exfiltrate data, execute commands, deliver payloads, or spread to other systems or networks.

Data masking is a technique that replaces sensitive data with fictitious or anonymized data, while preserving the original format and structure of the data. This way, the data can be used for testing purposes without revealing the actual Pll information. Data masking is one of the best practices for data analysis of confidential data1.

JavaScript Object Notation (JSON) is commonly used for transmitting data in web applications and would be suitable for updating dashboards that integrate various data sources. It ' s lightweight and easy to parse and generate.

The correct answer is B because the packet capture shows ICMP echo request traffic carrying data in the packet payload. ICMP echo requests are normally used for ping-style connectivity checks, not for transferring business data. The presence of millions of ICMP packets with payload data, combined with the fact that proprietary information is already appearing on the dark web, strongly indicates data exfiltration over an alternative protocol, often described as ICMP tunneling or protocol misuse.

The official CompTIA CySA+ CS0-003 objectives place this directly under Security Operations, specifically analyzing indicators of potentially malicious activity and using packet capture tools. The objectives explicitly include data exfiltration, unexpected outbound communication, packet capture, Wireshark, and tcpdump as relevant skills and tools for determining malicious activity.

Supporting extract from the CySA+ Study Guide: ICMP echo requests are produced by ping, and “Ping communications take place using the Internet Control Message Protocol (ICMP).” This confirms that the observed Type 8 echo request traffic is ICMP ping-style traffic, not a normal file-transfer or application protocol.

Supporting extract from the Secbay CySA+ guide: “Data Exfiltration: Unauthorized transfer of sensitive data from a system, potentially indicating a data breach or insider threat activity.” The same section also states that “Unexpected Outbound Communication” can indicate communication with malicious or unauthorized entities.

Why the other options are incorrect:

A is not the best answer because the evidence does not prove an insider or a command-and-control channel. The packet capture shows ICMP echo requests with data payloads, which points more directly to exfiltration.

C is incorrect because there is no evidence of malware propagation, scans, sweeps, or attempts to infect other systems.

D is incorrect because an ICMP DDoS would normally involve traffic intended to overwhelm a target. Here, the key indicator is data being carried inside ICMP echo request packets, and the business context is stolen proprietary information on the dark web.

Therefore, the most likely malicious activity is exfiltration over an alternative protocol.
