What are two types of intrusion prevention systems?Group of answer choicesPassive and ActiveInternal and externalHost and networkAnomaly and signature

To answer your question regarding the two types of intrusion prevention systems (IPS):

Types of Intrusion Prevention Systems

1. Passive and Active

   • Passive systems monitor network traffic and generate alerts, but they do not take any action to prevent intrusions.
   • Active systems, on the other hand, can take direct measures to prevent an intrusion, such as blocking traffic from suspicious sources.

2. Internal and External

   • Internal systems focus on monitoring and protecting against threats that originate from within an organization.
   • External systems are designed to monitor and protect the network from external threats and attacks.

3. Host and Network

   • Host-based IPS (HIPS) is installed on individual hosts or devices and monitors activities on that specific host.
   • Network-based IPS (NIPS) monitors network traffic as a whole in order to detect and prevent malicious activities.

4. Anomaly and Signature

   • Anomaly-based detection identifies deviations from a baseline of normal activity.
   • Signature-based detection relies on known patterns of malicious activity or signatures to identify threats.

Conclusion

Among these options, the most common classification divides intrusion prevention systems into Host and Network or Anomaly and Signature types. Depending on the context of the question, both terms could be considered valid.

If you need to choose one specific pair based on common academic classifications, Host and Network would be a suitable answer.
