Intrusion Prevention System Overview Answers 1. What is one of the main advantages of using an IPS? A. Less technical expertise required for maintenance B. Lower costs than traditional firewalls C. Increased protection against emerging threats D. Simplified deployment processes Answer: Increased protection against emerging threats (C) An IPS provides increased protection against emerging threats, making it a valuable asset in security. 2. Which function is NOT typically performed by an IPS? A. Performing backup data storage B. Denial-of-Service (DoS) mitigation C. Blocking malware infections D. Malicious traffic detection and prevention Answer: Performing backup data storage (A) Performing backup data storage is not a function of an IPS; its role is more focused on threat detection and prevention. 3. What factor can significantly impact the effectiveness of an IPS? A. Number of devices connected to the network B. Up-to-date IPS signatures C. Hardware specifications of the organization D. Speed of the network connection Answer: Up-to-date IPS signatures (B) The effectiveness of an IPS largely depends on having thorough and up-to-date signatures to detect threats accurately. 4. Which disadvantage is associated with deploying an IPS? A. Greater interoperability with legacy systems B. High cost compared to some security measures C. Comprehensive data monitoring D. Automatic updates with no manual intervention Answer: High cost compared to some security measures (B) High cost compared to some other security measures is a noted disadvantage when deploying an IPS. 5. Which future trend is expected in the development of IPS? A. Focus on manual threat response procedures B. Cloud-based IPS deployment for dynamic scaling C. Less reliance on integration with firewalls D. Reduction in the use of machine learning Answer: Cloud-based IPS deployment for dynamic scaling (B) The trend towards cloud-based IPS deployment allows for dynamic scaling and improved management options. 6. What is a primary function of an Intrusion Prevention System (IPS)? A. To provide real-time statistics on network traffic. B. To only alert on potential threats without taking action. C. To analyze and store historical data for later inspection. D. To actively block or mitigate identified threats. Answer: To actively block or mitigate identified threats. (D) An IPS actively intervenes to block or mitigate threats, distinguishing itself from an Intrusion Detection System (IDS) which primarily monitors. 7. Which deployment type allows an IPS to actively inspect traffic and intervene in the data stream? A. Passive deployment B. Dual-path deployment C. Inline deployment D. Federated deployment Answer: Inline deployment (C) Inline deployment places the IPS in the network path, enabling it to inspect and potentially block threats. 8. What distinguishes anomaly-based detection in IPS from signature-based detection? A. Anomaly-based detection only works on specific applications. B. Anomaly-based detection is slower than signature-based detection. C. Anomaly-based detection is less reliable than signature-based detection. D. Anomaly-based detection can identify new threats not previously known. Answer: Anomaly-based detection can identify new threats not previously known. (D) Anomaly-based detection identifies traffic deviating from normal behavior, enabling it to recognize zero-day exploits. 9. Which type of IPS monitors traffic for malicious activity specifically on individual devices? A. Cloud-based IPS B. Network-based IPS (NIPS) C. Host-based IPS (HIPS) D. Application-based IPS (APIs) Answer: Host-based IPS (HIPS) (C) Host-based IPS (HIPS) focuses on monitoring and filtering traffic on individual hosts or devices. 10. How does an advanced IPS utilize machine learning algorithms? A. To create fixed patterns for known threats. B. To learn and adapt to new, evolving attacks quickly. C. To ensure constant monitoring without any threat detection. D. To increase the volume of data stored for analysis. Answer: To learn and adapt to new, evolving attacks quickly. (B) Advanced IPS can learn through machine learning algorithms, enabling rapid recognition and reaction to evolving threats.
