  3. Fred is a network technician working for Johnson Services, a temporary employment agency in Boston. Johnson Services has three remote offices in New England and the headquarters in Boston where Fred works. The company relies on a number of customized applications to perform daily tasks and unfortunately these applications require users to be local administrators. Because of this, Fred’s supervisor wants to implement tighter security measures in other areas to compensate for the inherent risks in making those users local admins. Fred’s boss wants a solution that will be placed on all computers throughout the company and monitored by Fred. This solution will gather information on all network traffic to and from the local computers without actually affecting the traffic. What type of solution does Fred’s boss want to implement?

    • Fred’s boss wants Fred to monitor a NIPS system.
    • Fred’s boss wants to implement a HIDS solution.
    • Fred’s boss wants a NIDS implementation.
    • Fred’s boss wants to implement a HIPS solution.

    • 1-i,2-v,3-iii,4-ii
    • 1-iii,2-iv,3-v,4-i
  6. What is the correct order of activities that a IDS is supposed to attempt in order of detect an intrusion?

    • Prevention, Intrusion Monitoring, intrusion Detection, Response

  7. Larry is a network administrator working for a manufacturing company in Detroit. Larry is responsible for the entire company’s network which consists of 300 workstations and 25 servers. After using a hosted email service for a year, the company wants to cut back on costs and bring the email control internal. Larry likes this idea because it will give him more control over email. Larry wants to purchase a server for email but he does not want the server to be on the internal network because this might cause security risks. He decides to place the email server on the outside of the company’s internal firewall. There is another firewall connected directly to the Internet that will protect some traffic from accessing the email server; the server will essentially be place between the two firewalls. What logical area is Larry going to place the new email server into?

    • He is going to place the server in a Demilitarized Zone (DMZ).
    • He will put the email server in an IPSec zone.
    • For security reasons, Larry is going to place the email server in the company’s Logical Buffer Zone (LBZ).
    • Larry is going to put the email server in a hot-server zone.
  8. Stephanie is currently setting up email security so all company data is secured when passed through email. Stephanie first sets up encryption to make sure that a specific user’s email is protected. Next, she needs to ensure that the incoming and the outgoing mail has not been modified or altered using digital signatures. What is Stephanie working on?

    • Usability
    • Confidentiality
    • Availability
    • Data Integrity
  9. Which of the following interfaces uses hot plugging technique to replace computer components without the need to shut down the system?
