IPS Intrusion Prevention System

IPS Intrusion Prevention System

Network security is extremely important nowadays and this is why we have intrusion systems to make it a more secure place. Network Intrusion Detection System which is an intrusion prevention system is what lends protection to the. It is a form of network security that detects and prevents threats which it identifies. IPS continuously protects and monitors your networks and keeps on looking for any malicious incidents and if it does it instantly starts gathering information about them.  Then it reports such events to the administrators of the system along with taking preventive actions for example configuring firewalls that will prevent future attacks and closing access points etc. IPS can also be used to identify problems with the security policies of the companies, preventing network guests from violating the rules present in the policies and also deterring employees.

On any typical corporate network, there are several access points and you must be aware of the ways to monitor them to capture potential violation signs, imminent threats, and bad incidents. Today security is increasing so are the network threats which are becoming more sophisticated so monitoring will help in infiltrating the most robust solutions for security.

IPS Intrusion Prevention System

Prevention Types

There are different Types of Intrusion Detection System and is typically configured to utilize different approaches to shield the network from illegal access.

Policy-based : In this type of approach administrators configure their security policies according to the security policy of the organization and the infrastructure of the network.  In case of a violation of the policy an alert will be triggered and is immediately sent to the administrator's system.

Signature-based : This type of approach uses predefined signatures of well-known network threats.  In case of the initiation of the attack that matches patterns or signatures in the system, action is taken to prevent it.

Anomaly-based : This approach identifies any unexpected or abnormal behavior on the network/ in case anomaly is found, the system is going to block all the access to the target host at the pretty moment.

How did it work?

The working of the IPS is very simple and that is scanning all the networks to put in action Network Intrusion Detection System.  There are different threats and the system is designed to detect and prevent them all like

  • Viruses /worms
  • Denial of Service
  • Exploits Types
  • Distributed denial of service

The IPS executes real-time packet scrutiny, deeply going through every packet that travels through all the networks. In case of suspicion and malicious packets, the IPS will carry one of the below-mentioned actions

  • Replace removing the suspicious content by repacking payloads, removing infected attachments from emails/files, or by removing header information, etc.
  • Firewall reconfiguration  or Reprogramming is done to prevent similar attacks
  • Terminating the TCP session that is exploited and also blocked from the offending IP address or account from application access, targeting resources of networks or hosts unethically.

Different Types of Intrusion Detection System mentioned above is used to eliminate or repair all the malicious activities on networks like this.
