Free Access CompTIA CS0-003 New Release

 The first thing that must be done when starting an investigation is to secure the scene. Securing the scene involves isolating and protecting the area where the incident occurred, as well as any potential evidence or witnesses. Securing the scene can help prevent any tampering, contamination, or destruction of evidence, as well as any interference or obstruction of the investigation.

Agent-based vulnerability scanning is a method that involves installing software agents on the target systems or networks that can perform local scans and report the results to a central server or console. Agent-based vulnerability scanning can reduce network traffic, as the scans are performed locally and only the results are transmitted over the network. Agent-based vulnerability scanning can also provide more accurate and up-to-date results, as the agents can scan continuously or on-demand, regardless of the system or network status or location.

The Common Vulnerabilities and Exposures (CVE) is a public repository of standardized identifiers and descriptions for common cybersecurity vulnerabilities. It helps security analysts to identify, prioritize, and report on the most critical vulnerabilities in their systems and applications. The other options are not relevant for this purpose: Cyber Threat Intelligence (CTI) is a collection of information and analysis on current and emerging cyber threats; Cyber Analytics Repository (CAR) is a knowledge base of analytics developed by MITRE based on the ATT&CK adversary model; ATT&CK is a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations.References: According to the CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition1, one of the objectives for the exam is to “use appropriate tools and methods to manage, prioritize and respond to attacks and vulnerabilities”. The book also covers the usage and syntax of various cybersecurity frameworks and standards, such as CVE, CTI, CAR, and ATT&CK, in chapter 1. Specifically, it explains the meaning and function of each framework and standard, such as CVE, which provides a common language for describing and sharing information about vulnerabilities1, page 28. Therefore, this is a reliable source to verify the answer to the question.

A discovery scan is a type of web application scanning that involves identifying active, internet-facing web applications and their URIs, without performing any intrusive or in-depth tests. This type of scan can help to understand the scope and structure of a web application before conducting more comprehensive vulnerability scans12.
