30 Questions
What is the main purpose of intrusion prevention?
Detering an intrusion attempt
Which term describes the actions an organization undertakes when an intrusion event is detected?
Intrusion reaction
What does intrusion correction aim to achieve?
Restoring operations to a normal state
Which of the following is NOT a learning objective related to intrusion detection and prevention systems?
Explaining managerial controls importance
How are advanced technologies utilized in enhancing information security?
By enhancing the security of information assets
What distinguishes intrusion prevention from intrusion reaction?
Intrusion prevention deters intrusions, while intrusion reaction involves restoration.
What type of detection method collects statistical summaries by observing normal traffic?
Anomaly-based detection
Which detection method can better detect specialized, multisession attacks?
Stateful protocol analysis
Which detection method is most likely to generate many false positives?
Anomaly-based detection
Which detection method involves reviewing log files generated by servers and network devices?
Log file monitors
Which detection method requires much more processing capacity than others?
Anomaly-based detection
Which detection method may fail to detect intrusion unless the protocol fundamentally behaves abnormally?
Stateful protocol analysis
What is the purpose of the confidence value associated with an IDS?
To minimize the number of false positives
How does evasion impact IDPS technologies?
Alters the appearance of malicious activity without changing its effect
What is a false attack stimulus in the context of IDS testing scenarios?
An event that triggers alarms but is not an actual attack
What does a false negative indicate in the context of an IDS system?
A failure to identify and respond to an active attack
How does an organization's past performance measurements influence the confidence value in an IDS?
By providing a basis for trust in the IDS's alert accuracy
What role does encoding text characters play in evasion techniques against IDPS monitoring?
Helps in preventing the detection of attacks by IDPSs
What is a characteristic of active IDPS response?
Modifying the network environment in response to the intrusion
What is a failsafe feature that protects an IDPS from being circumvented?
Modifying the network environment
In terms of IDPS response behavior, what does passive response primarily involve?
Reporting collected information for administrator action
What should be considered when selecting IDPS approaches and products?
The scalability of the product for the environment
Which factor influences IDPS response to external stimulation?
Collection of additional information about intrusions
What aspect should be considered in relation to organizational requirements when selecting IDPS approaches?
Resource constraints within the organization
What is the key difference between fully distributed and partially distributed IDPS control?
Location of control functions
How does the partially distributed IDPS control approach benefit organizations?
Enables detection of widespread attacks
What is a crucial consideration when deploying components of an IDPS system?
Minimizing the impact on system performance
Why is selecting the right deployment strategy for an IDPS critical?
To meet the organization's security requirements with minimal impact
Which scenario best describes a situation where NIDPS and HIDPS are used together?
NIDPS covering internal network systems, HIDPS covering external systems
What feature makes fully distributed IDPS control different from partially distributed control?
Location of control functions
