NEW QUESTION # 221
Which of the following best describes root cause analysis?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Root cause analysis (RCA) is a post-incident activity focused on identifying the underlying cause of an incident/problem so the organization can fix the real cause (not just symptoms) and prevent recurrence. That matches Option B, which describes tracing the origin and eliminating it permanently.
The Sybex CySA+ Study Guide defines RCA in exactly this way:
Exact extract (Sybex Study Guide):
"The process of root cause analysis (RCA) is used to identify why a problem, incident, or issue occurred. Root cause analysis is performed to allow organizations to understand what they need to focus on to prevent future problems..." The Secbay Press guide also defines RCA as uncovering underlying causes to prevent recurrence:
Exact extract (Secbay Press):
"Root Cause Analysis (RCA)... is a systematic investigation process aimed at identifying the fundamental factors that led to a security incident. It goes beyond addressing symptoms and seeks to uncover the underlying causes to prevent recurrence." Why the other options are wrong A (TTPs): That describes attacker behavior frameworks (e.g., MITRE ATT&CK), not RCA.
C (who/what/when/where/why): That's an incident reporting structure, not the RCA process.
D (ongoing activities report): That resembles status reporting/incident updates, not root cause determination.
Reference (CompTIA CySA+ CS0-003 documents / study guides used):
Mike Chapple & David Seidl, CompTIA CySA+ Study Guide (CS0-003): RCA identifies why an incident occurred and helps prevent recurrence Secbay Press, CompTIA CySA+ Exam Prep Guide (CS0-003): RCA goes beyond symptoms to uncover underlying causes and prevent recurrence
NEW QUESTION # 222
During a cybersecurity incident, one of the web servers at the perimeter network was affected by ransomware.
Which of the following actions should be performed immediately?
Answer: D
Explanation:
Explanation
Quarantining the server is the best action to perform immediately, as it isolates the affected server from the rest of the network and prevents the ransomware from spreading to other systems or data. Quarantining the server also preserves the evidence of the ransomware attack, which can be useful for forensic analysis and law enforcement investigation. The other actions are not as urgent as quarantining the server, as they may not stop the ransomware infection, or they may destroy valuable evidence. Shutting down the server may not remove the ransomware, and it may trigger a data deletion mechanism by the ransomware. Reimaging the server may restore its functionality, but it will also erase any traces of the ransomware and make recovery of encrypted data impossible. Updating the OS to the latest version may fix some vulnerabilities, but it will not remove the ransomware or decrypt the data. Official References:

NEW QUESTION # 223
An XSS vulnerability was reported on one of the public websites of a company. The security department confirmed the finding and needs to provide a recommendation to the application owner. Which of the following recommendations will best prevent this vulnerability from being exploited? (Select two).
Answer: D,E
Explanation:
Comprehensive Detailed Explanation:To effectively prevent Cross-Site Scripting (XSS) attacks, implementing appropriate security controls within the application code and at the network layer is critical.
Here's a breakdown of each option:
* A. Implement an IPS in front of the web server
* Explanation: Intrusion Prevention Systems (IPS) are primarily designed to detect and prevent network-based attacks, not application-layer vulnerabilities such as XSS. They do not specifically mitigate XSS threats effectively.
* B. Enable MFA on the website
* Explanation: Multi-factor authentication (MFA) strengthens user authentication but does not address XSS, which typically involves injecting malicious scripts rather than compromising user credentials.
* C. Take the website offline until it is patched
* While this might temporarily mitigate the risk, it is not a practical solution for ongoing operations, especially when effective preventative controls (e.g., WAF rules or code updates) can be implemented without disabling the service.
* D. Implement a compensating control in the source code
* Explanation: Implementing security controls at the code level is an effective way to mitigate XSS risks. This can involve proper input validation, output encoding, and utilizing libraries that sanitize user inputs. By addressing the root cause in the source code, developers prevent scripts from being injected or executed in the browser.
* E. Configure TLS v1.3 on the website
* Explanation: While TLS v1.3 secures the communication channel, it does not address XSS directly. XSS attacks manipulate client-side scripts, which TLS cannot prevent, as TLS only encrypts data in transit.
* F. Fix the vulnerability using a virtual patch at the WAF
* Explanation: Web Application Firewalls (WAFs) can mitigate XSS vulnerabilities by identifying and blocking malicious payloads. Virtual patching at the WAF level provides a temporary fix by preventing exploit attempts from reaching the application, giving developers time to implement a permanent fix in the source code.
References:
* OWASP XSS Prevention Cheat Sheet: Detailed guidance on encoding, sanitizing, and safe coding practices to prevent XSS.
* NIST SP 800-44: Guidelines on Web Security, discussing WAFs and application-layer protections.
* CWE-79: Common Weakness Enumeration on Cross-Site Scripting, which outlines ways to address and prevent XSS attacks.
NEW QUESTION # 224
The Chief Information Security Officer (CISO) of a large management firm has selected a cybersecurity framework that will help the organization demonstrate its investment in tools and systems to protect its data.
Which of the following did the CISO most likely select?
Answer: A
Explanation:
ISO 27001 is an international standard that establishes a framework for implementing, maintaining, and improving an information security management system (ISMS). It helps organizations demonstrate their commitment to protecting their data and complying with various regulations and best practices. The other options are not relevant for this purpose: PCI DSS is a standard that focuses on protecting payment card data; COBIT is a framework that provides guidance on governance and management of enterprise IT; ITIL is a framework that provides guidance on service management and delivery.

check the explanation part below for the solution:
Explanation:
Part 1:
Part 2:
Based on the compliance report, I recommend the following changes for each server:
AppServ1: No changes are needed for this server.
AppServ2: Disable or upgrade TLS 1.0 and TLS 1.1 to TLS 1.2 on this server to ensure secure encryption and communication between clients and the server. Update Apache from version 2.4.17 to version 2.4.18 or greater on this server to fix any potential vulnerabilities or bugs.
AppServ3: Downgrade Apache from version 2.4.19 to version 2.4.18 or lower on this server to ensure compatibility and stability with the company's applications and policies. Change the port number from 8080 to either port 80 (for HTTP) or port 443 (for HTTPS) on this server to follow the default port convention and avoid any confusion or conflicts with other services.
AppServ4: Update Apache from version 2.4.16 to version 2.4.18 or greater on this server to fix any potential vulnerabilities or bugs. Change the port number from 8443 to either port 80 (for HTTP) or port 443 (for HTTPS) on this server to follow the default port convention and avoid any confusion or conflicts with other services.
