Sure, here is an SEO-friendly HTML answer for the interview question "Can you explain the difference between an IDS and an IPS in network security?":

Understanding the Difference Between IDS and IPS in Network Security

When it comes to network security, it's crucial to differentiate between IDS (Intrusion Detection System) and IPS (Intrusion Prevention System). These two play distinct roles in safeguarding networks from cyber threats. Let's break down the difference:

IDS (Intrusion Detection System)

An IDS is a passive monitoring tool that analyzes network traffic for suspicious activities and alerts the administrator when potential threats are detected. It serves as a watchdog, identifying intrusions and providing valuable insights for further analysis and response.

IPS (Intrusion Prevention System)

On the other hand, an IPS is an active security measure that not only detects intrusions but also takes immediate action to block or prevent them. It acts as a gatekeeper, inspecting network traffic in real-time and applying predetermined security policies to mitigate risks.

Overall, while an IDS notifies about potential security breaches, an IPS steps in to actively prevent them. Implementing both systems in a layered security approach can significantly enhance network protection against evolving cyber threats.

In conclusion, understanding the roles of IDS and IPS in network security is essential for deploying an effective defense strategy against cyber attacks.
