IDS and IPS detection and prevention systems: What are they for?

IDS and IPS Detection and Prevention Systems

There are many criminals who, hard, strive to gain free access to our systems, to obtain some kind of benefit: be directly economical - demanding a rescue to recover our information, such as after a ransomware attack -, or with the purpose of spy on the company, to achieve some competitive advantage. To fight against these intrusions, we currently have various means. And, with the help of Punt Informàtic, we can do so both reactively and proactively.


Monitor incoming traffic

Both the Intrusion Detection Systems (IDS) and the Intruder Prevention Systems (IPS) increase the security of our networks. Both systems are responsible for monitoring traffic, and for this they examine the network and ports, analyzing data packets, to detect suspicious patterns. The factor that ensures the success of an IDS or an IPS is its ability to identify already recognized firms. And the most prominent difference between the two systems is how they react when they have detected an attack.

The IDS contain an extensive updated database, with many known attack signatures. The IDS solution is responsible for monitoring incoming traffic - through an exhaustive network analysis and a port scan - and all this is compared with the information available on malicious elements. In the case of any suspicious activity, this detection system issues an early warning, which directs the system administrators. And it is these IT managers who must take appropriate action.

Decide on access control

On the other hand, the IPS emerged as extensions of the IDS solutions - with which they continue in relation -, and were developed to not only deal with the search for malicious activity, but also try to stop it. These proactive network security devices monitor traffic on a continuous basis, as well as all the activities of an IT environment. The IPS controls access in a computer network, protecting computer systems from abuse and attacks.

By locating traffic detection systems, IPSs resolve ambiguities in the tasks of passively monitoring computer networks. To combat potentially malicious activities, this software is capable of making decisions about access control, based on the contents of the traffic - instead of ports or IP addresses. Therefore, we must recognize that IPS represent a significant improvement over traditional firewall technologies.
