Question 1: Which of the following is an advantage of anomaly detection?
Rules are easy to define
Custom protocols can be easily analyzed
The engine can scale as the rule set grows
Malicious activity that falls within normal usage patterns is detected
Question 2: A false positive can be defined as ________
An alert that indicates nefarious activity on a system that, upon further inspection, turns out to represent legitimate network traffic or behavior
An alert that indicates nefarious activity on a system that is not running on the network
The lack of an alert for nefarious activity
Both An alert that indicates nefarious activity on a system that, upon further inspection, turns out to represent legitimate network traffic or behavior and An alert that indicates nefarious activity on a system that is not running on the network
Question 3: One of the most obvious places to put an IDS sensor is near the firewall. Where exactly in relation to the firewall is the most productive placement?
Inside the firewall
Outside the firewall
Both inside and outside the firewall
Neither inside the firewall nor outside the firewall.
Question 4: What is the purpose of a shadow honeypot?
To flag attacks against known vulnerabilities
To help reduce false positives in a signature-based IDS
To randomly check suspicious traffic identified by an anomaly detection system
To enhance the accuracy of a traditional honeypot
Question 5: At which two traffic layers do most commercial IDSes generate signatures?
Application layer and Network layer
Network layer and Session Layer
Transport layer and Application layer
Transport layer and Network layer
Question 6: IDS follows a two-step process consisting of a passive component and an active component. Which of the following is part of the active component?
Inspection of password files to detect inadvisable passwords
Mechanisms put in place to reenact known methods of attack and record system responses
Inspection of system to detect policy violations
Inspection of configuration files to detect inadvisable settings
Question 7: When discussing IDS/IPS, what is a signature?
An electronic signature used to authenticate the identity of a user on the network
Attack-definition file
It refers to “normal,” baseline network behavior
It is used to authorize the users on a network
Question 8: “Semantics-aware” signatures automatically generated by Nemean are based on traffic at which two layers?
Application layer and Transport layer
Network layer and Application layer
Session layer and Transport layer
Application layer and Session layer
Question 9: Which of the following is used to provide a baseline measure for comparison of IDSes?
Crossover error rate
False negative rate
False positive rate
Bit error rate
Question 10: Which of the following is true of signature-based IDSes?
They alert administrators to deviations from “normal” traffic behavior
They identify previously unknown attacks
The technology is mature and reliable enough to use on production networks
They scan network traffic or packets to identify matches with attack-definition files
