Updated CompTIA Cybersecurity Analyst (CySA+) CS0-001 Dumps Questions

1. SIMULATION

The developers recently deployed new code to three web servers. A daily automated external device scan report shows server vulnerabilities that are failing items according to PCI DSS. If the vulnerability is not valid, the analyst must take the proper steps to get the scan clean. If the vulnerability is valid, the analyst must remediate the finding. After reviewing the given information, select the STEP 2 tab in order to complete the simulation by selecting the correct “Validation Result” AND “Remediation Action” for each server listed using the drop down options.

Instructions:

If at any time you would like to bring back the initial state of the simulation, please select the Reset button. When you have completed the simulation, please select the Done button to submit. Once the simulation is submitted, please select the Next button to continue.

2. HOTSPOT

A security analyst suspects that a workstation may be beaconing to a command and control server. You must inspect the logs from the company’s web proxy server and the firewall to determine the best course of action to take in order to neutralize the threat with minimum impact to the organization.
