最新的 CompTIA CySA+ CS0-004 免費考試真題 (Q27-Q32):

問題 #27
A binary file that might contain malicious code is hosted on an isolated machine. An analyst wants to quickly detect the malicious code. Which of the following should the analyst use?

A. strings
B. Yet Another Recursive Acronym (YARA)
C. VirusTotal
D. WHOIS

答案：B

解題說明：
YARA scans files locally for patterns and signatures associated with known malware. It is appropriate for an isolated system, whereas VirusTotal requires uploading or querying the file online.

問題 #28
Which of the following best describes the reason a root cause analysis is an important part of the incident response process?

A. Compliance teams can be legally required to conduct a post-incident root cause analysis to satisfy regulatory requirements.
B. The leadership team can better allocate resources to address systemic issues that span multiple groups in an organization.
C. The organization can use the results of the analysis to provide stakeholders with assurances that customer data was not disclosed.
D. Response teams can use the analysis to isolate a system while the incident is ongoing to prevent further contamination.

答案：B

解題說明：
Root cause analysis identifies the underlying systemic issues that allowed the incident to occur, enabling leadership to address weaknesses across processes, technology, or teams and allocate resources effectively to prevent recurrence.

問題 #29
A security team reviews a penetration testing report of a web application that contains multiple cross-site scripting (XSS) and Structured Query Language injection (SQLi) vulnerabilities. Which of the following is most likely causing these to occur?

A. Lack of endpoint protection in the environment
B. Misconfigured web application firewall (WAF)
C. Lack of secure input validation
D. Lack of a Hypertext Transfer Protocol (HTTP) Strict Transport Security (HSTS) header

答案：C

解題說明：
Both XSS and SQL injection commonly occur when an application fails to properly validate, sanitize, and safely process untrusted user input.

問題 #30
A systems administrator reviews a ticket from a third-party SOC regarding a recent security event. The SOC provided the following table:

Which of the following is most likely the reason for the SOC ticket?

A. Impossible travel
B. Time-of-day restrictions
C. Brute-force authentication
D. Geoblocking policy

答案：A

解題說明：
The log entries show successful logins for the same user account from the United States and later from India within a relatively short period. Traveling between those locations in the elapsed time would be unrealistic, which is a classic indicator of impossible travel. This type of alert is commonly generated when authentication events occur from geographically distant locations in a timeframe that is physically impossible for a legitimate user.

問題 #31
A security analyst must identify documents that contain encoded ActiveMime payloads in a directory containing thousands of files. The analyst runs the following command: grep -rail ActiveMime * The command returns no output.
Which of the following Yet Another Recursive Acronym (YARA) rules should the analyst use to find the suspicious files?

答案：A

解題說明：
Option C represents the appropriate YARA matching approach because the analyst is searching for an encoded representation of ActiveMime , not necessarily the literal plaintext string. The grep -rail ActiveMime * command performs a case-insensitive recursive search for the textual value ActiveMime. If the payload contains that value encoded-commonly through Base64 or another transformed representation-the literal byte sequence will not be present and grep will therefore fail to identify it.
YARA is designed specifically for pattern-based identification of malicious or suspicious content. Its string modifiers support encoded representations. YARA's official documentation states that the base64 modifier searches for Base64-encoded forms of a specified string, while base64wide extends this behavior to wide- character representations. Therefore, a rule constructed to detect the encoded form of ActiveMime can identify relevant documents without requiring the literal plaintext sequence to occur in the file.
The essential examination concept is the distinction between literal text searching and malware-oriented encoded-pattern matching . Rules that search only for ordinary ASCII ActiveMime reproduce the limitation of the unsuccessful grep command.
