QUESTIONS AND ANSWERS GRADED A+
⩥ What is the purpose of continuous monitoring in system security?
Answer: To detect intrusions or malicious activity on the network.
⩥ What is the purpose of the 'key exchange' command in TLS? Answer:
It handles any part of the key exchange process.
⩥ What does the 'change cipher spec' command do in TLS? Answer: It
handles any adjustments to the key exchange process.
⩥ What is the significance of the 'finish' message in TLS? Answer: It
signifies that the SSL/TLS tunnel is established and setup is complete.
⩥ What is a system boundary? Answer: The point where data transfers
from the intranet to the internet and vice-versa.
⩥ Why is it important to document all applications and systems that
store or process data? Answer: To analyze the security architecture and
identify critical dependencies.
,⩥ What can happen if a system boundary is too large? Answer: It could
inherit risk from systems outside the administrative control of the
information system owner.
⩥ What is boundary protection? Answer: The monitoring and control of
communications at the external boundary of an information system.
⩥ What are some tools used for boundary protection? Answer:
Gateways, routers, firewalls, guards, and encrypted tunnels.
⩥ What does the CIA triad stand for? Answer: Confidentiality, Integrity,
and Availability.
⩥ What is a Demilitarized Zone (DMZ) in network architecture?
Answer: A subnet that separates an internal network from the internet,
typically using two firewalls.
⩥ What is the purpose of maintaining an inventory of network
boundaries? Answer: To keep an up-to-date record of all organizational
network boundaries.
⩥ What should be done to detect unauthorized connections across
trusted network boundaries? Answer: Perform regular scans from
outside each trusted network boundary.
,⩥ What is the recommendation for communication with known
malicious IP addresses? Answer: Deny communications with known
malicious or unused Internet IP addresses.
⩥ What is the principle of Least Privilege in network security? Answer:
To deny communications by default and allow them by exception.
⩥ What is the role of Network-based Intrusion Detection Systems
(NIDS)? Answer: To look for unusual attack mechanisms and detect
system compromise.
⩥ What is the function of Network-based Intrusion Prevention Systems
(NIPS)? Answer: To block malicious network traffic at the organization's
network boundaries.
⩥ What should be configured to record network packets at boundaries?
Answer: Monitoring systems should be configured to record network
packets passing through the boundary.
⩥ What is the purpose of deploying an application layer filtering proxy
server? Answer: To ensure that all network traffic passes through an
authenticated proxy that filters unauthorized connections.
, ⩥ What is the importance of understanding inbound and outbound traffic
for high-value systems? Answer: To ensure that traffic is documented
and controlled at the IP address, port, and protocol level.
⩥ What happens if critical dependencies are excluded from the system
boundary? Answer: It could affect the confidentiality, integrity, and
availability of the high-value system.
⩥ What is a multi-layered approach in boundary defense? Answer: An
approach focused on efficiently segmenting networks and controlling
data flow.
⩥ What is the significance of using firewalls and proxies in network
segmentation? Answer: They strengthen network segmentation and
enhance security.
⩥ What is the purpose of an application layer filtering proxy server?
Answer: To ensure all network traffic to/from the Internet passes through
an authenticated proxy that filters unauthorized connections.
⩥ What should be done with encrypted network traffic at the proxy?
Answer: Decrypt all encrypted network traffic at the boundary proxy
prior to analyzing the content.
