A security analyst scans a host and generates the following output:
Which of the following best describes the output?
A security analyst has received an incident case regarding malware spreading out of control on a customer's network. The analyst is unsure how to respond. The configured EDR has automatically obtained a sample of the malware and its signature. Which of the following should the analyst perform next to determine the type of malware, based on its telemetry?
Answer : A
The signature of the malware is a unique identifier that can be used to compare it with known malware samples and their behaviors. Open-source threat intelligence sources provide information on various types of malware, their indicators of compromise, and their mitigation strategies. By cross-referencing the signature with these sources, the analyst can determine the type of malware and its telemetry. The other options are not relevant for this purpose: configuring the EDR to perform a full scan may not provide additional information on the malware type; transferring the malware to a sandbox environment may expose the analyst to further risks; logging in to the affected systems and running netstat may not reveal the malware activity.
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 EDR, a tool used for endpoint security, in chapter 5. Specifically, it explains the meaning and function of malware signatures and how they can be used to identify malware types1, page 203. It also discusses the benefits and challenges of using open-source threat intelligence sources to enhance security analysis1, page 211. Therefore, this is a reliable source to verify the answer to the question.
While reviewing the web server logs, a security analyst notices the following snippet:
.. \ .. / .. \ .. /boot.ini
Which of the following Is belng attempted?
Answer : A
The snippet shows an attempt to access the boot.ini file, which is a configuration file for Windows operating systems. The ''... \ ... /'' pattern is used to navigate up the directory structure and reach the root directory, where the boot.ini file is located. This is a common technique for exploiting directory traversal vulnerabilities, which allow an attacker to access files and directories outside the intended web server path. The other options are not relevant for this purpose: remote file inclusion involves injecting a malicious file into a web application; cross-site scripting involves injecting malicious scripts into a web page; remote code execution involves executing arbitrary commands on a remote system; enumeration of /etc/passwd involves accessing the file that stores user information on Linux systems.
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 web server logs, which record the requests and responses of web applications, in chapter 6. Specifically, it explains the meaning and function of each component in web server logs, such as the HTTP method, the URL, the status code, and the user agent1, page 244. It also discusses the common types and indicators of web-based attacks, such as directory traversal, which use special characters to manipulate the web server path1, page 251. Therefore, this is a reliable source to verify the answer to the question.
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 dat
a. Which of the following did the CISO most likely select?
Answer : C
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.
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 ISO 27001, PCI DSS, COBIT, and ITIL, in chapter 1. Specifically, it explains the meaning and function of each framework and standard, such as ISO 27001, which provides a comprehensive approach to information security management1, page 29. Therefore, this is a reliable source to verify the answer to the question.
A vulnerability analyst is writing a report documenting the newest, most critical vulnerabilities identified in the past month. Which of the following public MITRE repositories would be best to review?
Answer : B
