Question 21

Refer to the exhibit.

A security analyst notices unusual connections while monitoring traffic. What is the attack vector, and which action should be taken to prevent this type of event?

Options:

A.

DNS spoofing; encrypt communication protocols

B.

SYN flooding; block malicious packets

C.

ARP spoofing; configure port security

D.

MAC flooding; assign static entries

Question 22

A new zero-day vulnerability is discovered in the web application. Vulnerability does not require physical access and can be exploited remotely. Attackers are exploiting the new vulnerability by submitting a form with malicious content that grants them access to the server. After exploitation, attackers delete the log files to hide traces. Which two actions should the security engineer take next? (Choose two.)

Options:

A.

Validate input upon submission.

B.

Block connections on port 443.

C.

Install antivirus.

D.

Update web application to the latest version.

E.

Enable file integrity monitoring.

Question 23

A cybersecurity analyst is analyzing a complex set of threat intelligence data from internal and external sources. Among the data, they discover a series of indicators, including patterns of unusual network traffic, a sudden increase in failed login attempts, and multiple instances of suspicious file access on the company's internal servers. Additionally, an external threat feed highlights that threat actors are actively targeting organizations in the same industry using ransomware. Which action should the analyst recommend?

Options:

A.

Advise on monitoring the situation passively because network traffic anomalies are coincidental and unrelated to the ransomware threat.

B.

Propose isolation of affected systems and activating the incident response plan because the organization is likely under attack by the new ransomware strain.

C.

Advocate providing additional training on secure login practices because the increase in failed login attempts is likely a result of employee error.

D.

Notify of no requirement for immediate action because the suspicious file access incidents are normal operational activities and do not indicate an ongoing threat.

Question 24

Refer to the exhibit.

An engineer received a ticket to analyze a recent breach on a company blog. Every time users visit the blog, they are greeted with a message box. The blog allows users to register, log in, create, and provide comments on various topics. Due to the legacy build of the application, it stores user information in the outdated MySQL database. What is the recommended action that an engineer should take?

Options:

A.

Validate input on arrival as strictly as possible.

B.

Implement TLS 1.3 for external communications.

C.

Match the web server software for the front-end and back-end servers.

D.

Upgrade the MySQL database.
