Chapter 2 - IT Security - Pre Quiz

What is the primary purpose of an Intrusion Detection System (IDS)?

• To prevent all cyber attacks

• To detect a wide range of security violations

• To encrypt network traffic

• To manage network bandwidth

What is a key advantage of Host-Based IDS?

• Lower cost

• More detailed logging

• Wider range of detection

• Easier deployment

What is a key consideration when placing Network-Based IDS?

• It must be placed where outbound packets are invisible

• It must be placed where inbound and outbound packets are visible

• It must be placed after encryption points

• It must be placed only at network endpoints

Which detection method takes the context of the established session into account?

• Pattern Matching

• Stateful Pattern Matching

• Protocol Decode based analysis

• Heuristic based analysis (based on practical experience and knowledge)

Which of the following is NOT one of the main benefits of implementing an IDS?

• Early detection

• Deterrence

• Network acceleration

• Future improvement through information collection

What is a key advantage of Network-Based IDS over Host-Based IDS?

• More detailed logging

• Lower cost of deployment

• Better detection of unknown attacks

• Increased recovery capabilities

What is a key advantage of Application Firewalls/IDS?

• High network performance

• Easy configuration

• Very granular policy setting

• No need for updates

What is the main difference between IPS and IDS?

• IPS is older technology

• IPS is reactive while IDS is proactive

• IPS is proactive while IDS tends to be reactive

• They are exactly the same

Layer Seven (Application layer) Switches are especially effective against which type of attack?

• Buffer overflow attacks

• SQL injection

• DoS attacks

• Man-in-the-middle attacks

Which type of IPS combines the features of host-based application firewall/IDS and layer seven switch?

• Inline IDS

• Deceptive Applications

• Hybrid Switches

• Network-based application IDS
