NEW QUESTION # 229
A security analyst is trying to identify anomalies on the network routing. Which of the following functions can the analyst use on a shell script to achieve the objective most accurately?
Answer: C
Explanation:
The function that can be used on a shell script to identify anomalies on the network routing most accurately is:
function x() { info=(dig(dig -x $1 | grep PTR | tail -n 1 | awk -F ".in-addr" '{print $1} ' ).origin.asn.cymru.
com TXT +short) & & echo "$1 | $info" }
This function takes an IP address as an argument and performs two DNS lookups using the dig command. The first lookup uses the -x option to perform a reverse DNS lookup and get the hostname associated with the IP address. The second lookup uses the origin.asn.cymru.com domain to get the autonomous system number (ASN) and other information related to the IP address. The function then prints the IP address and the ASN information, which can help identify any routing anomalies or inconsistencies
NEW QUESTION # 230
An analyst wants to ensure that users only leverage web-based software that has been pre-approved by the organization. Which of the following should be deployed?
Answer: D
Explanation:
The correct answer is B. Allowlisting.
Allowlisting is a technique that allows only pre-approved web-based software to run on a system or network, while blocking all other software. Allowlisting can help prevent unauthorized or malicious software from compromising the security of an organization. Allowlisting can be implemented using various methods, such as application control, browser extensions, firewall rules, or proxy servers12.
The other options are not the best techniques to ensure that users only leverage web-based software that has been pre-approved by the organization. Blocklisting (A) is a technique that blocks specific web-based software from running on a system or network, while allowing all other software. Blocklisting can be ineffective or inefficient, as it requires constant updates and may not catch all malicious software. Graylisting
is a technique that temporarily rejects or delays incoming messages from unknown or suspicious sources, until they are verified as legitimate. Graylisting is mainly used for email filtering, not for web-based software control. Webhooks (D) are a technique that allows web-based software to send or receive data from other web- based software in real time, based on certain events or triggers. Webhooks are not related to web-based software control, but rather to web-based software integration.
NEW QUESTION # 231
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
Explanation:
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.
NEW QUESTION # 232
An analyst is evaluating the following vulnerability report:
Which of the following vulnerability report sections provides information about the level of impact on data confidentiality if a successful exploitation occurs?
Answer: B
Explanation:
The correct answer is B. Metrics.
The Metrics section of the vulnerability report provides information about the level of impact on data confidentiality if a successful exploitation occurs. The Metrics section contains the CVE dictionary entry and the CVSS base score of the vulnerability. CVE stands for Common Vulnerabilities and Exposures and it is a standardized system for identifying and naming vulnerabilities. CVSS stands for Common Vulnerability Scoring System and it is a standardized system for measuring and rating the severity of vulnerabilities.
The CVSS base score is a numerical value between 0 and 10 that reflects the intrinsic characteristics of a vulnerability, such as its exploitability, impact, and scope. The CVSS base score is composed of three metric groups: Base, Temporal, and Environmental. The Base metric group captures the characteristics of a vulnerability that are constant over time and across user environments. The Base metric group consists of six metrics: Attack Vector, Attack Complexity, Privileges Required, User Interaction, Scope, and Impact. The Impact metric measures the effect of a vulnerability on the confidentiality, integrity, and availability of the affected resources.
In this case, the CVSS base score of the vulnerability is 9.8, which indicates a critical severity level. The Impact metric of the CVSS base score is 6.0, which indicates a high impact on confidentiality, integrity, and availability. Therefore, the Metrics section provides information about the level of impact on data confidentiality if a successful exploitation occurs.
The other sections of the vulnerability report do not provide information about the level of impact on data confidentiality if a successful exploitation occurs. The Payloads section contains links to request and response payloads that demonstrate how the vulnerability can be exploited. The Payloads section can help an analyst to understand how the attack works, but it does not provide a quantitative measure of the impact. The Vulnerability section contains information about the type, group, and description of the vulnerability. The Vulnerability section can help an analyst to identify and classify the vulnerability, but it does not provide a numerical value of the impact. The Profile section contains information about the authentication, times viewed, and aggressiveness of the vulnerability. The Profile section can help an analyst to assess the risk and priority of the vulnerability, but it does not provide a specific measure of the impact on data confidentiality.

NEW QUESTION # 233
A company is in the process of implementing a vulnerability management program. Which of the following scanning methods should be implemented to minimize the risk of OT/ICS devices malfunctioning due to the vulnerability identification process?
Answer: C
Explanation:
Passive scanning is a method of vulnerability identification that does not send any packets or probes to the target devices, but rather observes and analyzes the network traffic passively.
Passive scanning can minimize the risk of OT/ICS devices malfunctioning due to the vulnerability identification process, as it does not interfere with the normal operation of the devices or cause any network disruption. Passive scanning can also detect vulnerabilities that active scanning may miss, such as misconfigured devices, rogue devices or unauthorized traffic.
