Hardly any other industry is developing as rapidly as the IT industry. This results in a lot of good things, but it also always presents us with new challenges.
We can see this rapid development again and again in new cyber attacks.
It is therefore essential that the cyber security sector always stays up to date in order to be able to identify new potential threats. In the past, systems such as Endpoint Detection and Response (EDP), EPP and Network Traffic Analysis (NTA) that have helped companies identify threats at an early stage and counteract them. However, due to the rapid development of cyber crime, these programs often reach their limits and are too narrowly focused to meet needs.
XDR, which is making a name for itself as a new category in the cybersecurity industry, is intended to remedy the problems of the “old generation”. XDR stands for “X Detection and Response”, the “X” for “everything”.
Above all, it relies on omnipresence throughout the system, a capability that programs like EDR lack. Because their view is limited to their endpoint. Missing information has to be laboriously supplemented. Furthermore, too much time often passes before a threat is recognized and can finally be solved. In addition, the frequency of alerts is often far too high to be able to process all of them, so some alerts have to be ignored, which in the worst case can pose a serious threat.
These are exactly the points that XDR wants to remedy. In contrast to EDR, data from endpoints, logs clouds and the local network are combined with general threat information. Viewing the system as a whole means being able to react more quickly to incidents and alerts and ultimately solve them.
The information collected by XDR is recognized more quickly and blocked better thanks to state-of-the-art analysis functions. Automated triage, investigation and response processes provide information to make confident decisions about processes that cannot be automated. Alerts are grouped into events in order to significantly reduce the number of individual warnings and significantly speed up the time to response.
The SIEM is one of the most important facilities for providing an overview of a company's IT security. The XDR also benefits from this information and, together with a SIEM, forms a bulwark that significantly simplifies the detection and response to cyber threats.
In conclusion, XDR is a new method of looking at the entirety of a system and:
