   Which of the following would BEST identify potential indicators of compromise?

   • Use Burp Suite to capture packets to the SCADA device’s IP.
   • Use tcpdump to capture packets from the SCADA device IP.
   • Use Wireshark to capture packets between SCADA devices and the management system.
   • Use Nmap to capture packets from the management system to the SCADA devices.

10. A cyber-incident response analyst is investigating a suspected cryptocurrency miner on a company’s server.

    Which of the following is the FIRST step the analyst should take?

    • Create a full disk image of the server’s hard drive to look for the file containing the malware.
    • Run a manual antivirus scan on the machine to look for known malicious software.
    • Take a memory snapshot of the machine to capture volatile information stored in memory.
    • Start packet capturing to look for traffic that could be indicative of command and control from the miner.

11. An information security analyst is compiling data from a recent penetration test and reviews the following output:

    

    The analyst wants to obtain more information about the web-based services that are running on the target.

12. A compliance officer of a large organization has reviewed the firm’s vendor management program but has discovered there are no controls defined to evaluate third-party risk or hardware source authenticity. The compliance officer wants to gain some level of assurance on a recurring basis regarding the implementation of controls by third parties.

    Which of the following would BEST satisfy the objectives defined by the compliance officer? (Choose two.)

    • Executing vendor compliance assessments against the organization’s security controls
