CompTIA Updated CS0-003 Exam Questions and Answers by kane

The analyst will be creating TTPs (Tactics, Techniques, and Procedures). TTPs describe the behavior, methods, and patterns used by attackers during a cyber attack. By focusing on TTPs, the analyst can develop a dynamic detection strategy that identifies malicious activities based on the observed behavior and patterns, rather than relying on static indicators like signatures or IOCs (Indicators of Compromise).

SOAR (Security Orchestration, Automation, and Response) is the best option to help the analyst implement the recommendation, as it reflects the software solution that enables security teams to integrate and coordinate separate tools into streamlined threat response workflows and automate repetitive tasks. SOAR is a term coined by Gartner in 2015 to describe a technology that combines the functions of security incident response platforms, security orchestration and automation platforms, and threat intelligence platforms in one offering. SOAR solutions help security teams to collect inputs from various sources, such as EDR agents, firewalls, or SIEM systems, and perform analysis and triage using a combination of human and machine power. SOAR solutions also allow security teams to define and execute incident response procedures in a digital workflow format, using automation to perform low-level tasks or actions, such as blocking an IP address or quarantining a device. SOAR solutions can help security teams to improve efficiency, consistency, and scalability of their operations, as well as reduce mean time to detect (MTTD) and mean time to respond (MTTR) to threats. The other options are not as suitable as SOAR, as they do not match the description or purpose of the recommendation. SIEM (Security Information and Event Management) is a software solution that collects and analyzes data from various sources, such as logs, events, or alerts, and provides security monitoring, threat detection, and incident response capabilities. SIEM solutions can help security teams to gain visibility, correlation, and context of their security data, but they do not provide automation or orchestration features like SOAR solutions. SLA (Service Level Agreement) is a document that defines the expectations and responsibilities between a service provider and a customer, such as the quality, availability, or performance of the service. SLAs can help to manage customer expectations, formalize communication, and improve productivity and relationships, but they do not help to implement technical recommendations like SOAR solutions. IoC (Indicator of Compromise) is a piece of data or evidence that suggests a system or network has been compromised by a threat actor, such as an IP address, a file hash, or a registry key. IoCs can help to identify and analyze malicious activities or incidents, but they do not help to implement response actions like SOAR solutions.

Mean time to detect (MTTD) is a metric that measures the average time it takes for an organization to discover or detect an incident. It is a key performance indicator in incident management and a measure of incident response capabilities. A low MTTD indicates that the organization can quickly identify security threats and minimize their impact12.

Wiresharkis apacket capture and analysis toolthat allows analysts to inspect network traffic and detectcleartext credentialssent over protocols like HTTP, FTP, and Telnet​.

Option A (OpenVAS)is avulnerability scanner, not a network analysis tool.

Option B (Angry IP Scanner)identifiesactive hosts, but does not analyze packet contents.

Option D (Maltego)is used forOSINT and network reconnaissance, not packet inspection.

Thus,C (Wireshark) is the correct answer, as itcaptures and analyzes network packets to identify unencrypted passwords​.
