SIEM: an omniscient surveillance system?

Security information and event management

With constant creativity, cyber attackers are forcing companies to continuously monitor and protect their information flows. Given the unimaginable number of data and information that cross the virtual wall of the company, only a computer program can process them in their entirety to sort out what represents a threat or not: this is the role of SIEM.

SIEM: monitor, process and sort

Because the analysis of data and sources that interact with the company exceed the skills of a human being, the SIEM (Security Information and Event Management) monitors in real time all activities and events on the network and computer park of the company. The data collected by the program are processed and sorted according to their nature so that those responsible for the computer system are alerted quickly in the event of suspicious movement.

The advantages of SIEM

SIEM is an easy and efficient solution that offers features that go far beyond monitoring and alerting. By saving logs, logs or interaction history, the system gives engineers the ability to understand the real circumstances and different processes followed by hackers during an intrusion attempt. This will identify the equipment and users that have facilitated intrusion or piracy. On the other hand, the SIEM succeeds in thwarting the most sophisticated attempts insofar as it equips itself with an algorithm allowing it to correlate various isolated information.

SIEM: an ally for the respect of security rules

Usually, a SIEM is set up following a security audit that revealed the flaws in a company’s IT system. Since the audit leads, in principle, to the development of a new security policy, the software analyses activities and events to report on their compliance with the terms of the new provisions.
