                          CompTIA Cybersecurity Analyst (CySA+) Certification Exam Sample Questions (Q473-Q478):

                          NEW QUESTION # 473
                          A code review reveals a web application is using lime-based cookies for session management.
                          This is a security concern because lime-based cookies are easy to:

                          Answer: B

                          Explanation:
                          Lime-based cookies (which are typically simple, predictable, or weakly-generated cookies) present a security risk because they are easy to guess, making them susceptible to session hijacking and other attacks. Attackers can easily determine the cookie value if the method used for generation is not strong or random enough, leading to unauthorized access.


                          NEW QUESTION # 474
                          A vulnerability management team is unable to patch all vulnerabilities found during their weekly scans. Using the third-party scoring system described below, the team patches the most urgent vulnerabilities:

                          Additionally, the vulnerability management team feels that the metrics Smear and Channing are less important than the others, so these will be lower in priority. Which of the following vulnerabilities should be patched first, given the above third-party scoring system?

                          Answer: C

                          Explanation:
                          The vulnerability that should be patched first, given the above third-party scoring system, is:
                          TSpirit: Cobain: Yes Grohl: Yes Novo: Yes Smear: No Channing: No
                          This vulnerability has three out of five metrics marked as Yes, which indicates a high severity level. The metrics Cobain, Grohl, and Novo are more important than Smear and Channing, according to the vulnerability management team. Therefore, this vulnerability poses a greater risk than the other vulnerabilities and should be patched first.


                          NEW QUESTION # 475
                          An analyst is conducting monitoring against an authorized team that win perform adversarial techniques. The analyst interacts with the team twice per day to set the stage for the techniques to be used. Which of the following teams is the analyst a member of?

                          Answer: A

                          Explanation:
                          The correct answer is A. Orange team.
                          An orange team is a team that is involved in facilitation and training of other teams in cybersecurity. An orange team assists the yellow team, which is the management or leadership team that oversees the cybersecurity strategy and governance of an organization. An orange team helps the yellow team to understand the cybersecurity risks and challenges, as well as the roles and responsibilities of other teams, such as the red, blue, and purple teams12.
                          In this scenario, the analyst is conducting monitoring against an authorized team that will perform adversarial techniques. This means that the analyst is observing and evaluating the performance of another team that is simulating real-world attacks against the organization's systems or networks. This could be either a red team or a purple team, depending on whether they are working independently or collaboratively with the defensive team345.
                          The analyst interacts with the team twice per day to set the stage for the techniques to be used. This means that the analyst is providing guidance and feedback to the team on how to conduct their testing and what techniques to use. This could also involve setting up scenarios, objectives, rules of engagement, and success criteria for the testing. This implies that the analyst is facilitating and training the team to improve their skills and capabilities in cybersecurity12.
                          Therefore, based on these descriptions, the analyst is a member of an orange team, which is involved in facilitation and training of other teams in cybersecurity.
                          The other options are incorrect because they do not match the role and function of the analyst in this scenario.
                          Option B is incorrect because a blue team is a defensive security team that monitors and protects the organization's systems and networks from real or simulated attacks. A blue team does not conduct monitoring against an authorized team that will perform adversarial techniques, but rather defends against them345.
                          Option C is incorrect because a red team is an offensive security team that discovers and exploits vulnerabilities in the organization's systems or networks by simulating real-world attacks. A red team does not conduct monitoring against an authorized team that will perform adversarial techniques, but rather performs them345.
                          Option D is incorrect because a purple team is not a separate security team, but rather a collaborative approach between the red and blue teams to improve the organization's overall security. A purple team does not conduct monitoring against an authorized team that will perform adversarial techniques, but rather works with them345.

                          NEW QUESTION # 476
                          A security engineer is reviewing security products that identify malicious actions by users as part of a company's insider threat program. Which of the following is the most appropriate product category for this purpose?

                          Answer: D

                          Explanation:
                          UEBA stands for User and Entity Behavior Analytics, which is a category of security products that use machine learning and statistical analysis to identify malicious actions by users or entities on a network. UEBA products can detect anomalous or suspicious behaviors that deviate from normal patterns or baselines, such as data exfiltration, privilege escalation, unauthorized access, insider threats, or compromised accounts. UEBA products can also provide alerts, reports, or recommendations for response actions based on the detected behaviors.


                          NEW QUESTION # 477
                          An analyst is reviewing processes running on a Windows host. The analyst reviews the following information:

                          Which of the following processes should the analyst review first?

                          Answer: B

                          Explanation:
                          The analyst should review PID 768 first because it is the parent process of another suspicious process (PID
                          1100) and it is also highly suspicious itself due to its unexpected file path.
                          Why PID 768 is the best first process to review
                          * Path anomaly (strong IoC): Legitimate Windows binaries like calc.exe and cmd.exe are normally found in trusted OS directories (e.g., C:\Windows\System32\). In the table, both CALC.exe and CMD.exe appear in a user's Documents folder (C:\Users\JDoe\Documents\...). That is a classic sign of masquerading (a malicious binary using a legitimate-sounding name). The All-in-One guide explicitly describes how attackers disguise malicious processes by using legitimate-sounding names and mimicking system processes.
                          * Parent-child relationship (investigation priority): PID 1100 (Documents\CMD.exe) is suspicious, but it is a child of PID 768 (Documents\CALC.exe). Investigating the parent first helps you understand what spawned the suspicious child, what activity preceded it, and whether PID 768 is the root of the execution chain. The All-in-One guide highlights that analysts should examine process parent-child relationships and investigate unexpected dependencies as a way to detect malicious activity:Exact extract (All-in-One Exam Guide): "Analyze process dependencies Examine process parent-child relationships and investigate any unexpected or unusual dependencies that may indicate malicious activity." It also emphasizes monitoring grandparent/parent/child relationships to detect deviations from normal process hierarchies:Exact extract (All-in-One Exam Guide): "Monitoring the relationships between processes, particularly grandparent, parent, and child relationships, can be a valuable method for detecting unusual activity."
                          * Abused/LOLBIN context: cmd.exe is a commonly abused Windows utility in attacks. The Sybex Study Guide notes that attackers often abuse built-in tools and that abnormal OS process behavior involving tools like cmd.exe can indicate compromise:Exact extract (Sybex Study Guide): "For Windows systems, a handful of built-in tools are most commonly associated with attacks like these, including cmd.exe..." Why the other options are less correct
                          * A (533) and B (740) are running from C:\Windows\System32\... which is the expected location for legitimate Windows binaries in normal circumstances, so they're less suspicious than the copies running from a user Documents folder.
                          * D (1100) is suspicious, but it is a child of PID 768. Investigating 768 first helps determine the origin and execution chain that led to the suspicious cmd instance.
