IDS and IPS: Similarities and differences between intrusion tools

The Intruder Detection System (IDS) and the Intruder Prevention System (IPS) prevent network intrusions in complementary ways.

Network data is usually protected by routers, firewalls or switches. Such technologies reduce the risks of those who work with the web, but in addition to having a configuration that requires advanced technical knowledge, in some cases they also allow undue access that leads to cyber attacks. It is through this loophole that IDS - Intrusion detection system and IPS - Intrusion prevention system.

Both the Intrusion Detection System (IDS) and the Intrusion Prevention System (IPS) are security techniques capable of detecting and preventing unauthorized access to networks and hosts. A switch, a router or a desktop server is enough for this system to be deployed or installed with software through hardware that fulfills the functions on your network. Although both perform the same function - that of preventing such unauthorized access -, they have some points that make them different.

what is the difference between IDS and IPS Security ?

Although very similar and with the function of providing security, the difference between IDS and IPS is in the way the service is presented. With regard to security, IDS is a passive system, while IPS is a system with active solutions. This is shown when, when it comes to acting, IDS shows itself as software that automates the procedure of detecting an intruder and IPS shows itself as software that prevents and prevents cyber attacks.

That is why the IDS is called a detector and the IPS is called a preventer. As soon as the IDS detects something suspicious, it logs this information (log) and sends an alert. Finally, it suspends the suspicious user's session and through the Firewall blocks network traffic from the suspected threat.

With IPS in use, it provides rules and policies for network traffic. The help of IDS makes it possible for the IPS to send its suspicious traffic alerts to administrators and also to provide all systems security, ranging from operational to data packages.
