An existing enterprise architecture included an enclave where sensitive research and developmentwork was conducted. This network enclave also served as a storage location for proprietarycorporate data and records. The initial security architect chose to protect the enclave by restrictingaccess to a single physical port on a firewall. All downstream network devices were isolated fromthe rest of the network and communicated solely through the single 100mbps firewall port. Overtime, researchers connected devices on the protected enclave directly to external resources andcorporate data stores. Mobile and wireless devices were also added to the enclave to support highspeed data research. Which of the following BEST describes the process which weakened thesecurity posture of the enclave?
- A.
Emerging business requirements led to the de-perimiterization of the network.
- B.
Emerging security threats rendered the existing architecture obsolete.
- C.
The single firewall port was oversaturated with network packets.
- D.
The shrinking of an overall attack surface due to the additional access.
Correct Answer
A. Emerging business requirements led to the de-perimiterization of the network.Explanation
The correct answer is "Emerging business requirements led to the de-perimeterization of the network." This means that as the business needs evolved, the network architecture shifted away from a perimeter-based security model where all devices were isolated behind a single firewall port. Instead, devices on the protected enclave started connecting directly to external resources and corporate data stores, and mobile and wireless devices were added. This weakened the security posture of the enclave as it allowed for more direct access to sensitive data and increased the potential attack surface.Rate this question:

Each client is assigned a set of virtual hosts running shared hardware. Virtual storage is partitioned and assigned to each client. VLAN technology is used to segment each of the client’s networks. PKI based remote desktop access is used by the client to connect to the application.
Correct Answer
C. Each client is assigned a set of virtual hosts running shared hardware. Physical storage is partitioned into LUNS and assigned to each client. MPLS technology is used to segment and encrypt each of the client’s networks. PKI based remote desktop with hardware tokens is used by the client to connect to the application.Explanation
In this scenario, the best design for prioritizing data confidentiality is to assign each client a set of virtual hosts running shared hardware. The physical storage is partitioned into LUNS and assigned to each client, ensuring that their data is kept separate. MPLS technology is used to segment and encrypt each client's networks, providing an additional layer of security. The use of PKI-based remote desktop with hardware tokens adds another level of authentication and secure access for the clients. This design ensures that each client's data is kept confidential and protected from unauthorized access.Rate this question:

A financial institution wants to reduce the costs associated with managing and troubleshootingemployees’ desktops and applications, while keeping employees from copying data onto externalstorage. The Chief Information Officer (CIO) has asked the security team to evaluate four solutionssubmitted by the change management group. Which of the following BEST accomplishes thistask?
- A.
Implement desktop virtualization and encrypt all sensitive data at rest and in transit.
- B.
Implement server virtualization and move the application from the desktop to the server.
- C.
Implement VDI and disable hardware and storage mapping from the thin client.
- D.
Move the critical applications to a private cloud and disable VPN and tunneling.
Correct Answer
C. Implement VDI and disable hardware and storage mapping from the thin client.Explanation
Implementing VDI (Virtual Desktop Infrastructure) allows the financial institution to centralize desktop management and troubleshooting, reducing costs associated with managing and troubleshooting employees' desktops and applications. By disabling hardware and storage mapping from the thin client, employees are prevented from copying data onto external storage, ensuring data security. This solution effectively addresses the CIO's objective of reducing costs and preventing data leakage.Rate this question:

A health service provider is considering the impact of allowing doctors and nurses access to theinternal email system from their personal smartphones. The Information Security Officer (ISO) hasreceived a technical document from the security administrator explaining that the current emailsystem is capable of enforcing security policies to personal smartphones, including screen lockoutand mandatory PINs. Additionally, the system is able to remotely wipe a phone if reported lost orstolen. Which of the following should the Information Security Officer be MOST concerned withbased on this scenario? (Select THREE).
- A.
The email system may become unavailable due to overload.
- B.
Compliance may not be supported by all smartphones.
- C.
Equipment loss, theft, and data leakage.
- D.
Smartphone radios can interfere with health equipment.
- E.
Data usage cost could significantly increase.
- F.
Not all smartphones natively support encryption.
- G.
Smartphones may be used as rogue access points.
Correct Answer(s)
B. Compliance may not be supported by all smartphones.
C. Equipment loss, theft, and data leakage.
F. Not all smartphones natively support encryption.Explanation
The Information Security Officer should be most concerned with the following based on the scenario:
1. Compliance may not be supported by all smartphones: This is a concern because if not all smartphones support the necessary security policies, it could create vulnerabilities in the system.
2. Equipment loss, theft, and data leakage: Allowing doctors and nurses to access the internal email system from their personal smartphones increases the risk of equipment loss, theft, and potential data leakage if the phones are not properly secured.
3. Not all smartphones natively support encryption: Encryption is an important security measure to protect sensitive data. If not all smartphones natively support encryption, it could pose a risk to the confidentiality of the information being transmitted.Rate this question:
