NEW QUESTION # 108
Heather has been tasked with setting up and implementing VPN tunnels to remote offices. She will most likely be implementing IPsec VPN tunnels to connect the offices. At what layer of the OSI model does an IPsec tunnel function on?

A. They work on the network layer
B. They function on either the application or the physical layer.
C. They work on the session layer.
D. They function on the data link layer

Answer: A

Explanation:
IPsec VPN tunnels operate at the network layer of the OSI model. This is because IPsec is designed to secure IP communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of a session and negotiation of cryptographic keys to be used during the session. IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). By functioning at the network layer, IPsec VPNs are able to secure all traffic that passes through them, not just specific applications or sessions.

NEW QUESTION # 109
Which of the following is an example of MAC model?

A. Chinese Waterfall model
B. Access control matrix model
C. Clark-Beason integrity model
D. Bell-LaPadula model

Answer: D

Explanation:
The Bell-LaPadula model is an example of a Mandatory Access Control (MAC) model. It is designed to maintain the confidentiality of information by enforcing access controls based on security classification levels.
This model ensures that subjects (users) with a certain clearance level cannot read data at a higher classification level (no read-up) and cannot write data to a lower classification level (no write-down), thus preventing unauthorized access and information flow not permitted by the policy.
References: The Bell-LaPadula model is a foundational concept in computer security, particularly within the context of government and military applications where data classification and confidentiality are paramount12.
