CompTIA CySA+ Certification Exam CS0-001 Dumps V13.02

1. CORRECT TEXT

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 information provided in the network diagram, select the STEP 2 tab to complete the simulation by selecting the correct Validation Result and Remediation Action for each server listed using the drop-down options.

Instructions STEP 1: Review the information provided in the network diagram. STEP 2: Given the scenario, determine which remediation action is required to address the

vulnerability. If at any time you would like to bring back the initial state of the simulation, please select the Reset All button.

2. DRAG DROP

You suspect that multiple unrelated security events have occurred on several nodes on a corporate network. You must review all logs and correlate events when necessary to discover each security event by clicking on each node. Only select corrective actions if the logs shown a security event that needs remediation. Drag and drop the appropriate corrective actions to mitigate the specific security event occurring on each affected device.

Instructions:

The Web Server, Database Server, IDS, Development PC, Accounting PC and Marketing PC are clickable. Some actions may not be required and each actions can only be used once per node.

The corrective action order is not important. 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.

3. HOTSPOT

A security analyst suspects that a workstation may be beaconing to a command and control server. 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.
