Q

A corporate workstation was recently infected with malware. The malware was able to access the workstation’s credential store and steal all the usernames and passwords from the machine. Then, the malware began to infect other workstations on the network using the usernames and passwords it stole from the first workstation. The IT Director has directed their IT staff to come up with a plan to prevent this type of issue from occurring again in the future. Which of the following would BEST prevent this from reoccurring?

  • Install a host-based intrusion detection system on all of the corporate workstations
  • Install an antivirus or antimalware solution that uses heuristic analysis
  • Install a Unified Threat Management system on the network to monitor for suspicious traffic
  • Monitor all workstations for failed login attempts and forward them to a centralized SYSLOG server
A
  • Install an antivirus or antimalware solution that uses heuristic analysis

The only solution provided that could STOP this from reoccurring would be to use an antivirus or antimalware solution with heuristic analysis. The other options might be able to monitor and detect the issue, but not stop it from spreading. Heuristic analysis is a method employed by many computer antivirus programs designed to detect previously unknown computer viruses, as well as new variants of viruses already in the wild. This is behavior-based detection and prevention, so it should be able to detect the issue in the scenario provided and stop it from spreading throughout the network.

38
Q

39
Q

Your company recently suffered a small data breach that was caused by an employee emailing themselves a copy of the current customer’s names, account numbers, and credit card limits. You are determined that something like this shall never happen again. Which of the following logical security concepts should you implement to prevent a trusted insider from stealing your corporate data?

  • Firewall
  • MDM
  • DLP
  • Strong passwords
A
  • DLP

Data loss prevention software detects potential data breaches/data ex-filtration transmissions and prevents them by monitoring, detecting and blocking sensitive data while in use (endpoint actions), in motion (network traffic), and at rest (data storage). Since the user was an authorized user (employee), changing your password policy, reconfiguring the firewall, or setting up a MDM solution would not solve this problem. Instead, a DLP solution must be implemented.

40
Q

A small doctor’s office has asked you to configure their network to use the highest levels of wireless security and desktop authentication.

Q

A user has reported that their workstation is running very slowly. A technician begins to investigate the issue and notices a lot of unknown processes running in the background. The technician determines that the user has recently downloading a new application from the Internet and may have become infected with malware. Which of the following types of infections does the workstation MOST likely have?

  • Rootkit
  • Keylogger
  • Trojan
  • Ransomware
A
  • Trojan

A trojan is a type of malware that looks legitimate but can take control of your computer. A Trojan is designed to damage, disrupt, steal, or in general, inflict some other harmful action on your data or network. The most common form of a trojan is a Remote Access Trojan (RAT), which is used to allow an attacker to remotely control a workstation or steal information from it. To operate, a trojan will create numerous processes that run in the background of the system.

42
Q

A computer was recently infected with a piece of malware. Without any user intervention, the malware is now spreading throughout the corporate network and infecting other computers that it finds. Which type of malware MOST likely infected these computers?

  • Worm
  • Virus
  • Trojan
  • Ransomware
A
  • Worm

A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. A worm can spread on its own, whereas a virus needs a host program or user interaction to propagate itself.

43
Q

You are working as a penetration tester and have discovered a new method of exploiting a vulnerability within the Windows 10 operating system. You conduct some research online and discover that a security patch against this particular vulnerability doesn’t exist yet. Which type of threat would this BEST be categorized as?

  • Zero day
  • DDOS
  • Brute Force
  • Spoofing
A
  • Zero day

A zero-day attack happens once that flaw, or software/hardware vulnerability, is exploited and attackers release malware before a developer has an opportunity to create a patch to fix the vulnerability—hence “zero-day.”

44
Q

A cybersecurity analyst in your company notices that an attacker is trying to crack the WPS pin associated with a wireless printer. The device logs show that the attacker tried 00000000, 00000001, 00000002, and continued to increment by 1 number each time until they found the correct PIN of 13252342. Which of the following type of password cracking was being performed by the attacker?

  • Rainbow table
  • Dictionary
  • Hybrid
  • Brute force
A
  • Brute force

Brute-force attack when an attacker uses a set of predefined values to attack a target and analyze the response until he succeeds. Success depends on the set of predefined values. If it is larger, it will take more time, but there is a better probability of success. In a traditional brute-force attack, the passcode or password is incrementally increased by one letter/number each time until the right passcode/password is found.

45
Q

A cybersecurity analyst is auditing your company’s network logs and identifies that a USB mass storage device was previously inserted into many of the company’s servers. The logs also showed that there were dozens of failed login attempts prior to a successful login occurring on the servers. Which TWO of the following actions are recommended to eliminate the vulnerabilities identified by the cybersecurity analyst?

  • Change the default credentials on the servers
  • Remove administrative permissions
  • Modify the autorun settings
  • Install the operating system security updates
  • Lockout the account after 3 failed login attempts
A
  • Modify the autorun settings
  • Lockout the account after 3 failed login attempts

Since the USB mass storage device was used to connect to the servers, it is recommended to modify the AutoRun settings. To prevent the password guessing attacks used, the servers should be configured to lockout any account after 3 failed login attempts.

46
Q

Your company works as a contractor to the military and has just finished replacing about 500 workstations across their secure network. You have been asked to properly dispose of the workstations and to destroy the data on their hard disk drives. Which of the following methods would be the MOST effective?

  • Physically destroy the drives by drilling each HDD’s platter
  • Fully format each hard drive with a series of 0s
  • Conduct a low-level format of each hard drive
  • Degauss each of the hard drives
A
  • Degauss each of the hard drives

Degaussing is the process of erasing/wiping a hard disk drive or magnetic tape. When exposed to the powerful magnetic field of a degausser, the magnetic data on a hard disk is neutralized or erased. Degaussing is the guaranteed form of hard drive erasure and is considered fast and efficient, especially with large numbers of hard drives. While the other options will erase or delete the data, they are much more time consuming since each drive must be formatted or destroyed individually. With an industrial degausser, multiple hard drives can be destroyed at once and they take less than a minute to degauss the hard drives.

47
Q

A workstation was patched last night with the latest operating system security update. This morning, the workstation only displays a black screen. You restart the computer, but the operating system fails to load. What is the NEXT step you should attempt to boot this workstation?

A
  • Rebuild your Windows profile
49
Q

A user receives the following error message: “Windows Update cannot currently check for updates because the service is not running.” The user calls the help desk to report the error they received. A support technician uses a remote connection tool to login to the computer remotely, quickly identifies the issue, and fixes the issue. Which of the following should the technician do NEXT?

  • Reboot the computer
  • Restart the network services
  • Roll back the device drivers
  • Register the windows update service’s DLL files
A
  • Reboot the computer

If any of the .DLL files involved with Windows Update are not correctly registered, you may also encounter this problem. To solve it, open services.msc and stop the Windows Update service. Then, open a Command Prompt as the administrator and use regsvr32 for each of the 6 Windows Update DLL files (wuapi.dll, wuaueng.dll, wups.dll, wups2.dll, wuwebv.dll, and wucltux.dll). Then, open services.msc and restart the Windows Update service. Finally, restart your computer for these changes to take effect.

Q

Sam and Mary both work in the accounting department and use a web-based software as part of their job. Sam is unable to login to the website using his credentials from his computer, but Mary is able to login with her credentials on her computer. Sam asks Mary to login to her account from his computer to see if the problem is with his account or his computer. When Mary attempts to login on Sam’s computer, she receives an error. Mary notices a pop-up notification about a new piece of software on Sam’s computer when she attempted to login to the website. Which TWO of the following steps should Mary take to resolve the issue with logging in from Sam’s computer?

  • Ask Sam for his username/password in order to log on to the website from Mary’s computer
  • Have Sam attempt to log on to another website from Sam’s computer to see if it works
  • Have Sam clear his browser cache on his computer and then attempt to log on to the website again
  • Verify Sam’s computer has the correct web browser configuration and settings
  • Ask Sam about the popup notification and determine what new programs he installed on his computer
A
  • Verify Sam’s computer has the correct web browser configuration and settings
  • Ask Sam about the popup notification and determine what new programs he installed on his computer

Since Mary was able to log in to the website from her computer but not from Sam’s, this indicates an issue with Sam’s computer and/or web browser. The pop-up notification about the new program being installed is a clue that something exists on Sam’s computer that doesn’t on Mary’s computer, therefore it could be the cause and should be investigated further. Additionally, the browser’s configuration should be checked to ensure the correct settings are being used.

Q

Edward has just returned to his office after a two-week vacation. When he logs into his email client to access his company email, he notices that he cannot see the shared Customer Service inbox folder in his email client. He contacts the help desk and they verify that his account is still connected to the domain controller and it can still send and receive emails successfully. What is the MOST likely happened during Edward’s vacation that is causing the missing inbox folders in the email client?

  • The network file share’s permissions has been modified
  • The operating system was updated
  • Edward’s user account permission was changed
  • The internet security options in his email client have been modified
A
  • The network file share’s permissions has been modified

While Edward was on vacation, it is likely that the network file share’s permissions have been modified. Based on the fact that Edward’s account is connected to the domain and is able to send/receive email, it cannot be his user account’s permissions causing the issue. The internet security options would also prevent him from sending/receiving mail, so that can be eliminated. Even if the operating system was updated, that would not affect the shared inboxes since they reside on the network file shares and not Edward’s computer.

Q

A factory worker suspects that a legacy workstation is infected with malware. The workstation is running Windows XP and is used as part of an ICS/SCADA system to control some industrial factory equipment. The workstation is connected to an isolated network that cannot reach the internet. The workstation receives the patterns for the manufactured designs through a USB drive. A technician is dispatched to remove the malware from this workstation, and after its removal, the technician provides the factory worker with a new USB drive to move the pattern files to the workstation. Within a few days, the factory worker contacts the technician again to report the workstation appears to be reinfected with malware. Which of the following steps did the technician MOST likely forget to perform to prevent a reinfection?

  • Quarantine the infected system
  • Disable System restore (in windows)
  • Remediate the infected systems
  • Update the anti-malware solution
  • Enable System Restore and create a restore point (in windows)
  • Identify and research malware symptons
A
  • Update the anti-malware solution

Since the workstation is isolated from the internet, the anti-malware solution will need to be manually updated to ensure it has the latest virus definitions. Without the latest virus definitions, the system can easily become reinfected.

Q

An Android user recently cracked their screen and had it replaced. If they are in a dark room, the phone works fine. But, if the user enters a room with normal lights on then the phone’s display is dim and hard to read. What is MOST likely the problem?

  • Defective display
  • Auto-brightness is disabled
  • Faulty ambient light sensor
  • Low battery
A
  • Faulty ambient light sensor

The ambient light sensor appears to be broken or malfunctioning. The ambient light sensor may be too sensitive as it is taking in more light than usual. This can occur if the sensor is faulty or if the screen was replaced incorrectly and the technician forgot to install the black gasket around the ambient light sensor.

Q

You are a member of a project team that is being contracted to install twenty new wireless access points (WAPs) for a college campus. Your team has already determined the locations for the new WAPs and notated them in the physical and logical network diagrams. Your team is still finalizing the change request documents for the installation. The project cannot move forward with the installation until the change request is finalized and approved. Which of the following is the MOST important thing to add to the SOW and change request prior to its approval?

  • Risk Analysis
  • Backout plan
  • Plan for change
  • End user acceptance
A
  • Backout plan

A backout plan is an IT governance integration approach that specifies the processes required to restore a system to its original or earlier state, in the event of failed or aborted implementation. Any installation or upgrade should include a backout plan as part of the change request and change plan. That way, if something goes wrong with the installation then the team can “backout” and restore service on the legacy/previous system.

57
Q

After installation or change has been implemented, which of the following is necessary prior to closing out the change request?

  • Change boards approval
  • End user acceptance
  • Risk analysis
  • Plan for the change
A
  • End user acceptance

After the installation or implementation of the change, the end-user acceptance must be received. If the end-user hasn’t approved the installation or change, then the project or ticket cannot be closed out.

Q

You have been asked to replace a computer’s hard drive. Which of the following steps should you take FIRST to prevent an electrical hazard while working on the computer?

  • Place the computer on a grounded work bench
  • Disconnect the power prior to serving the computer
  • Place the computer and it’s components on an ESD mat
  • Connect an ESD strap to yourself to prevent shock
A
  • Disconnect the power prior to serving the computer

The FIRST thing that you need to do is disconnect the power to the computer. This will eliminate many electrical hazards and prevent you from getting an electrical shock while working on the machine. After it is disconnected, then it is a good idea to use an ESD strap, place the computer and its components on an ESD mat, and work on the computer on top of a grounded work bench.

Q

A user is unable to open some files on a file server and contacts the help desk for support. The help desk technician begins to troubleshoot the server and notices that all of the data backups for the server are operational, but there are large portions of time missing within the event log. The technician remembers that there have been several bad thunderstorms recently during those missing time periods. What might the technician do to prevent these server issues in the future?

  • Replace the servers memory
  • Install a surge protector
  • Replace the servers hard drive
  • Install a new battery backup
A
  • Install a new battery backup

The missing time periods in the event logs indicates that the server was powered off during those periods. This is likely to have occurred due to a power loss during the thunderstorms. To prevent these power losses, it is recommended that the servers be connected to a batter backup. When a server is powered off due to a power loss, files can become corrupted and unusable.

Q

A programmer is writing a script to calculate the amount of disk space needed to perform a daily backup. The programming needs to store the amount of disk space in a temporary place holder within the program that can be updated and changed during the script’s execution. Which of the following would be used to store the value of the disk space needed?

  • Loop
  • Comment
  • Constant
  • Variable
A
  • Constant

A variable is a placeholder in a script that can contain a number, character, or string or characters. Variables in scripts do not have to be declared (unlike in programming languages), but instead can simply be assigned a value. Then, the variable name is referenced throughout the script instead of the value itself.
