Question 4 A university wants to increase the security posture
of its network by implementing vulnerability scans of both centrally managed and student/employee laptops.
Question 5 A cybersecurity analyst is
completing an organization"™s vulnerability report and wants it to reflect assets accurately. Which of the following items should be in the report?
Question 6 A threat intelligence feed has posted an alert stating there is a critical vulnerability in the kernel. Unfortunately, the company"™s asset inventory is not current. Which of the following techniques would a cybersecurity analyst perform to find all affected servers within an organization?
Question 7 A cybersecurity analyst traced the source
of an attack to compromised user credentials. Log analysis revealed that the attacker successfully authenticated from an unauthorized foreign country. Management asked the security analyst to research and implement a solution to help mitigate attacks based on compromised passwords. Which of the following should the analyst implement?
Question 8 A technician is running an intensive vulnerability scan to detect which ports are open to exploit. During the scan, several network services are disabled and production is affected. Which of the following sources
would be used to evaluate which network service was interrupted?
Question 9 A software patch has been released to
remove vulnerabilities from company"™s software. A security analyst has been tasked with testing the software to ensure the vulnerabilities have been remediated and the application is still functioning properly. Which of the following tests should be performed NEXT?
Answer : C Explanation: Question 10 During a routine review of firewall logs, an analyst identified that an IP address from the organization"™s server subnet had been connecting during
nighttime hours to a foreign IP address, and had been sending between 150 and 500 megabytes of data each time. This had been going on for approximately one week, and the affected server was taken offline for forensic review. Which of the following is MOST likely to drive up the incident"™s impact assessment?
Question 11 A security analyst is performing a forensic analysis on a machine that was the subject of some historic SIEM alerts. The analyst noticed some network connections utilizing SSL on non-common ports, copies of svchost.exe and cmd.exe in %TEMP% folder, and RDP files that had connected to external IPs. Which of the following threats has the security analyst uncovered?
Question 12 A threat intelligence analyst who works for a technology firm received this report from a vendor. "There has been an intellectual property theft campaign executed against organizations in the technology
industry. Indicators for this activity are unique to each intrusion. The information that appears to be targeted is R&D data. The data exfiltration appears to occur over months via uniform TTPs. Please execute a defensive operation regarding this attack vector."
Question 13The help desk informed a security analyst of a trend that is beginning to develop regarding a suspicious email that has been reported by multiple users. The analyst has determined the email includes an attachment named invoice.zip that contains the following files: Locky.js -
Question 14 After running a packet analyzer on the network, a security analyst has noticed the following output: Which of the following is occurring?
Question 15 A network technician is concerned that an attacker is attempting to penetrate the network, and wants to set a rule on the firewall to prevent the attacker from learning which IP addresses are valid on the network. Which of the following protocols needs
to be denied?
What type of document typically contains high level statements of management intent?Policy. A policy is a high-level statement of management intent that formally establishes requirements to guide decisions and achieve rational outcomes. Essentially, a policy is a statement of expectation, that is enforced by standards and further implemented by procedures.
Which of the following tools could be used to detect unexpected output from an application being managed or monitored?Which of the following tools could be used to detect unexpected output from an application being managed or monitored? OBJ-3: A behavior-based analysis tool can be used to capture/analyze normal behavior and then alert when an anomaly occurs.
Which analysis framework is essentially a repository of known IOCs with ties to known specific threats?Which analysis framework is essentially a repository of known IOCs with ties to known specific threats? OpenIOC is essentially just a flat database of known indicators of compromise.
Which of the following methods would be the most efficient to use to sanitize the affected hard drives?Sanitizing a hard drive can be done using cryptographic erase (CE), secure erase (SE), zero-fill, or physical destruction. In this case, the hard drives already used data at rest. Therefore, the most efficient method would be to choose CE.
