Question 1

Intrusion detection and prevention systems can deal effectively with switched networks.

Accepted Answer

False

Question 2

The Simple Network Management Protocol contains trap functions, which allow a device to send a message to the SNMP management console indicating that a certain threshold has been crossed, either positively or negatively.

Accepted Answer

The statement is correct. SNMP trap functions allow devices to send messages to the SNMP management console to indicate when specific thresholds have been reached.

Question 3

Your organization's operational goals, constraints, and culture should not affect the selection of the IDPS and other security tools and technologies to protect your systems.

Accepted Answer

The organization's operational goals, constraints, and culture should be taken into account when selecting IDPS and other security tools and technologies, as they can affect the deployment and effectiveness of these solutions. For example, if an organization has limited resources or is focused on agility, they may prioritize IDPS solutions that are easy to implement and manage, while a highly regulated organization may require specific features or certifications. Additionally, an organization's culture can impact the level of user training and awareness needed to effectively use and maintain security tools.

Question 4

The process by which attackers change the format and/or timing of their activities to avoid being detected by the IDPS is known as a false attack stimulus.

Accepted Answer

The process by which attackers change the format and/or timing of their activities to avoid being detected by the IDPS is known as evasion. False attack stimulus refers to a false positive generated by the IDPS, which triggers an alert for an attack that is not actually happening.

Question 5

All IDPS vendors target users with the same levels of technical and security expertise.

Accepted Answer

IDPS vendors typically have different product offerings that target users with different levels of technical and security expertise. Some products may be designed for beginners or small businesses with limited resources, while others may be geared towards advanced users or large enterprises with complex security needs. Therefore, it is not accurate to say that all IDPS vendors target users with the same levels of technical and security expertise.

Question 6

HIDPSs are also known as system integrity verifiers.

Accepted Answer

HIDPSs (Host Intrusion Detection and Prevention Systems) are designed to verify system integrity by monitoring and analyzing system behavior, detecting and preventing intrusions, and ensuring system compliance with security policies.

Question 7

An HIDPS can monitor system logs for predefined events.

Accepted Answer

HIDPS stands for Host Intrusion Detection and Prevention System, which is designed to detect and prevent intrusions on a host system. One of its capabilities is to monitor system logs for predefined events, such as unauthorized access attempts or suspicious activities.

Question 8

A false positive is the failure of an IDPS system to react to an actual attack event.

Accepted Answer

A false positive is actually the opposite, where the IDPS system generates an alert or takes an action in response to a benign activity, mistaking it as an attack event.

Question 9

IDPS responses can be classified as active or passive.

Accepted Answer

IDPS (Intrusion Detection and Prevention System) responses can be classified as active or passive. Active responses take action to block or prevent the intrusion, whereas passive responses simply alert the system administrator or log the event for further analysis.

Question 10

A passive IDPS response is a definitive action automatically initiated when certain types of alerts are triggered.

Accepted Answer

A passive IDPS response involves monitoring and alerting, rather than taking direct action to stop or mitigate the detected threat.

Question 11

NIDPSs can reliably ascertain whether an attack was successful.

Accepted Answer

NIDPSs (Network Intrusion Detection and Prevention Systems) can detect and sometimes prevent attacks by analyzing network traffic, but they cannot reliably ascertain whether an attack was successful because they lack visibility into the outcome of the attack within the target system.

Question 12

The anomaly-based IDPS collects statistical summaries by observing traffic that is known to be normal.

Accepted Answer

An anomaly-based IDPS examines traffic that is considered to be normal, collecting statistical summaries of the observed traffic to build a baseline of normal behavior. It then uses this baseline to detect any deviations from the expected behavior and alert security personnel to potential security threats.

Question 13

An HIDPS is optimized to detect multihost scanning, and it is able to detect the scanning of non-host network devices, such as routers or switches.

Accepted Answer

The answer of An HIDPS is optimized to detect multihost...

Question 14

An IDPS can be configured to dial a phone number and produce an alphanumeric page or other type of signal or message.

Accepted Answer

IDPS can be configured to send alerts via phone calls, text messages, emails, or other types of signals.

Question 15

In order to determine which IDPS best meets an organization's needs, first consider the organizational environment in technical, physical, and political terms.

Accepted Answer

To select the best IDPS for an organization, it is important to consider the technical, physical, and political environment of the organization. This will help in identifying the specific security risks, evaluating the capabilities of the IDPS, and ensuring that it aligns with the organizational goals and policies.

Question 16

An HIDPS can detect local events on host systems and detect attacks that may elude a network-based IDPS.

Accepted Answer

HIDPS stands for Host-based Intrusion Detection and Prevention System. It is installed on individual host systems and monitors the activity on those systems to detect any suspicious activity or behavior. Since it is installed locally, it has access to information and events that a network-based IDPS may not be able to detect. Therefore, an HIDPS can detect local events on host systems and detect attacks that may elude a network-based IDPS.

Question 17

In DNS cache poisoning, valid packets exploit poorly configured DNS servers to inject false information and corrupt the servers' answers to routine DNS queries from other systems on the network.

Accepted Answer

DNS cache poisoning occurs when valid packets exploit poorly configured DNS servers to inject false information and corrupt the servers' answers to routine DNS queries from other systems on the network.

Question 18

Intrusion detection consists of procedures and systems that identify system intrusions and take action when an intrusion is detected.

Accepted Answer

The answer of Intrusion detection consists of procedures and systems...

Question 19

Intrusion detection and prevention systems perform monitoring and analysis of system events and user behaviors.

Accepted Answer

Intrusion detection and prevention systems are designed to monitor and analyze system events and user behaviors in order to identify and prevent potential security threats.

Question 20

A fully distributed IDPS control strategy is an IDPS implementation approach in which all control
functions are applied at the physical location of each IDPS component.

Accepted Answer

In a fully distributed IDPS control strategy, all control functions are applied at each physical location, making it a fully decentralized approach.
