CompTIA CS0-003 Exam

The best way to prevent network printers from printing pages during a vulnerability scan is to create a tailored scan for the printer subnet that excludes the ports and services that trigger the printing behavior. The other options are not effective for this purpose: performing non-credentialed scans may not reduce the impact on the printers; ignoring embedded web server ports may not cover all the possible ports that cause printing; increasing the threshold length of the scan timeout may not prevent the printing from occurring.

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 vulnerability scanning tools, such as Nessus, Nmap, and Qualys, in chapter 4. Specifically, it explains the meaning and function of each component in vulnerability scanning, such as credentialed vs. non-credentialed scans, port scanning, and scan scheduling1, pages 149-160. It also discusses the common issues and challenges of vulnerability scanning, such as network disruptions, false positives, and scan scope1, pages 161-162. Therefore, this is a reliable source to verify the answer to the question.

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.

Reference: 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.

The output shows that port 80 is open and running an HTTP service, indicating that the host could potentially be vulnerable to web-based attacks.The other options are not relevant for this purpose: the host is responsive to the ICMP request, as shown by the ''Host is up'' message; the host is not running a mail server, as there is no SMTP or POP3 service detected; the host is not allowing unsecured FTP connections, as there is no FTP service detected. Reference:According to the CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition123, 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 nmap, a popular network scanning tool, in chapter 5.Specifically, it explains the meaning and function of each option in nmap, such as ''-sV'' for version detection2, page 195. Therefore, this is a reliable source to verify the answer to the question.

The security analyst is validating a Local File Inclusion (LFI) vulnerability, as indicated by the ''/.../.../.../'' in the GET request which is a common indicator of directory traversal attempts associated with LFI. The other options are not relevant for this purpose: SQL injection involves injecting malicious SQL statements into a database query; XSS involves injecting malicious scripts into a web page; CSRF involves tricking a user into performing an unwanted action on a web application.

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 Burp Suite, a tool used for testing web application security, in chapter 6. Specifically, it explains the meaning and function of each component in Burp Suite, such as Repeater, which allows the security analyst to modify and resend individual requests1, page 239. Therefore, this is a reliable source to verify the answer to the question.

An incident response plan (IRP) is a document that defines the roles and responsibilities, procedures, and guidelines for responding to a security incident. It helps the security team to act quickly and effectively, minimizing the impact and cost of the incident. An IRP should specify who should conduct the next steps following a security event, such as containment, eradication, recovery, and analysis12. Reference: CompTIA CySA+ CS0-003 Certification Study Guide, page 362; 6 Incident Response Steps to Take After a Security Event, section 2.
