Guide to Intrusion Detection and Prevention Systems (IDPS)
Intrusion Detection and Prevention Systems (IDPS) are critical tools for network security. They work by monitoring network and system activities for suspected malicious activities or policy violations and reports them to management stations. In some cases, the systems might respond to mitigate the potential impact.
Importance: The importance of IDPS lies in their ability to provide a second line of defense against threats that can bypass other security measures. They actively work to contain, stop, or divert threats, reducing the potential damage.
Working: IDPS work in two key ways. An intrusion detection system (IDS) detects possible intrusions and then reports them to the system or network administrator. On the other hand, an intrusion prevention system (IPS) not only detects but also prevents the intrusion attempt by blocking it or taking other preventive measures.
