NEW QUESTION # 173
A security analyst is reviewing events that occurred during a possible compromise. The analyst obtains the following log:
Which of the following is most likely occurring, based on the events in the log?
Answer: D
Explanation:
Based on the events in the log, the most likely occurrence is that an adversary is performing a vulnerability scan. The log shows LDAP read operations and EDR enumerating local groups, which are indicative of an adversary scanning the system to find vulnerabilities or sensitive information. The final entry shows SMB connection attempts to multiple hosts from a single host, which could be a sign of network discovery or lateral movement.

NEW QUESTION # 174
Several incidents have occurred with a legacy web application that has had little development work completed. Which of the following is the most likely cause of the incidents?
Answer: A
Explanation:
Outdated libraries in a legacy web application introduce security vulnerabilities, as they lack modern patches and contain known exploits.
* Option A (Misconfigured WAF) can contribute to security issues but is not inherent to legacy applications.
* Option B (Data integrity failure) is a potential impact but not a direct cause of recurring incidents.
* Option D (Insufficient logging) affects detection, but the root cause is insecure, outdated components.
Thus, C (Outdated libraries) is the correct answer, as legacy applications frequently suffer from unpatched vulnerabilities.
NEW QUESTION # 175
A security analyst is tasked with prioritizing vulnerabilities for remediation. The relevant company security policies are shown below:
Security Policy 1006: Vulnerability Management
1. The Company shall use the CVSSv3.1 Base Score Metrics (Exploitability and Impact) to prioritize the remediation of security vulnerabilities.
2. In situations where a choice must be made between confidentiality and availability, the Company shall prioritize confidentiality of data over availability of systems and data.
3. The Company shall prioritize patching of publicly available systems and services over patching of internally available system.
According to the security policy, which of the following vulnerabilities should be the highest priority to patch?
Answer: B
Explanation:
To determine the correct priority, you must filter the options by applying the rules from Security Policy 1006 in the order of importance dictated by the scenario.
"The Company shall prioritize patching of publicly available systems and services over patching of internally available system."
* Option A: Internal System
* Option B: External System (Keep)
* Option C: External System (Keep)
* Option D: Internal System
Result: Eliminate Options A and D. We are now choosing between B and C.
"In situations where a choice must be made between confidentiality and availability, the Company shall prioritize confidentiality of data over availability of systems and data." To apply this, you must read the CVSS v3.1 Vector String for the remaining options. The relevant metrics are C (Confidentiality) and A (Availability).
* Option B (CAP.SHIELD): C:H / I:N / A:N
* Confidentiality: High (C:H)
* Availability: None (A:N)
* Interpretation: This vulnerability allows for a significant breach of data confidentiality.
* Option C (LOKI.DAGGER): C:N / I:N / A:H
* Confidentiality: None (C:N)
* Availability: High (A:H)
* Interpretation: This vulnerability allows for a significant disruption of service (DoS).
Conclusion: Since the policy explicitly prioritizes Confidentiality (Option B) over Availability (Option C), Option B is the highest priority.
The exam expects you to parse raw CVSS strings to assess risk. Here is the breakdown for the correct answer (Option B):
Metric
Code
Value
Meaning
AV
AV:N
Network
The vulnerability is exploitable remotely via the network (most dangerous).
AC
AC:L
Low
No complex conditions are required to exploit.
PR
PR:N
None
No privileges are required (unauthenticated).
UI
UI:N
None
No user interaction is required.
C
C:H
High
Confidentiality Impact. Total loss of confidentiality.
A
A:N
None
Availability Impact. No impact to uptime.
NEW QUESTION # 176
While reviewing web server logs, a security analyst discovers the following suspicious line:
Which of the following is being attempted?
Answer: B
Explanation:
The suspicious line in the web server logs is an attempt to execute a command on the server, indicating a command injection attack.References: CompTIA CySA+ Study Guide: Exam CS0-003, 3rd Edition, Chapter
5, page 197; CompTIA CySA+ CS0-003 Certification Study Guide, Chapter 5, page 205.
NEW QUESTION # 177
An organization identifies a method to detect unexpected behavior, crashes, or resource leaks in a system by feeding invalid, unexpected, or random data to stress the application. Which of the following best describes this testing methodology?
Answer: C
Explanation:
Fuzzing is a testing technique where invalid or random data is inputted into a system to find vulnerabilities, crashes, or unexpected behaviors. It's commonly used in software security to identify flaws that could lead to security breaches. According to CompTIA's CySA+ curriculum, fuzzing is a dynamic testing method for exposing application weaknesses. Options like static testing (B) involve analyzing code without execution, while reverse engineering (A) and debugging (D) involve different methodologies for understanding or fixing code, not intentionally stressing it.
