An IDS or network intrusion detection system is a network security device that monitors network and/or system activities for malicious activity or policy violations. It is important to note that IPS does not just detect like an Intrusion Detection System (IDS) does, but it blocks or prevents any type of attacks.
How IPS Works
IPS usually operates in inline mode meaning that it is between the incoming traffic and the going traffic. It examines network traffic to identify malicious signatures, abnormalities, and other suspicious activity. It can then do a few things like:
Traffic Blocking: Blocking bad traffic at point A so it does not make the journey to B.
Alerting: Registering to security admins like a possible hazard
Connection Resets: Dropping bad things.
Packet Dropping: This process discards the packets which are malicious in behavior.
Key Features of IPS
SignatureDetection:Bases on identifiable patterns to find common attack types
Anomaly-Based Approach: This technique identifies abnormalities deviate from standard network traffic behaviour.
Protocol Analysis – The protocol analysis helps to analyze network protocols for any exploitable vulnerabilities.
Intrusion Prevention: Blocks or minimizes attacks instead of waiting for them to occur.
Live danger intelligence: Uses threat intelligence feeds to remain updated on the latest danger threats.
Benefits of Using an IPS
Proactive Defense — IPS can stop an attack before it can cause any harm.
Improved Security Posture: Integration with other security devices and systems can allow IPS to substantially improve network security.
Decreased Threats of Data Breaches: Sensitive data remains secure against unauthorized access with IPS.
Enhanced Compliance: IPS may help organizations meet security compliance regulations and industry standards.
Conclusion
An Intrusion Prevention System (IPS) is the best tool you can possess within its arsenal for organisations looking to safeguard their network against cyber threats. IPS can fortify the security posture of an organization by utilizing ultra-modern strategies to identify and alleviate zero-day threats beforehand.
