What is a security information and event management system (SIEM)?

Sharing is caring!

It is a reality that cybercrime is on the rise, the attacks suffered by companies of all kinds worldwide are increasingly numerous and more sophisticated if possible, which makes it almost impossible to combat them and minimize their impact on society.

Attacks that not many years ago were carried out for fun or for gaining knowledge and practice in digital security; It has become a multi-million dollar business, which does not seem to hit the ceiling and has continued economic growth. Both governments and private companies have to dedicate, year after year, multimillion-dollar budget items, to try to combat and mitigate cybercrime attacks.


Only a few clicks separate us from an endless number of attack modalities (DDoS, Botnets, malware installation, Spam or Phising emails, …), with which any user, whether home or business, can be surprised, in the simplest way and without realizing it, contribute to compromising the security of your home or company.

We can insist that the traditional virus protection softwares, such as the famous antivirus on the personal computers of each user. They are outdated to be able to face with high number of attacks and their great diversity; as well as the negative effects they can cause.

To all this, we must add the moment we live in, with the Big Data boom, and it is that we cannot ignore the large amounts of data that are currently collected in companies, from different places, systems and platforms. It contributes to making attacks and security break more costly, both economically and in time and effort necessary for their management.

The SIEM centralizes storage and enables near real-time analysis of what is happening in security management. In this way, it is possible to detect abnormal accessibility patterns and give greater visibility to security systems.

For its part, the SIEM collects long-term data in a central repository for analysis. In this way, you can provide automated reports to IT security personnel. Both features allow you to act more quickly on cybersecurity incidents or attacks. The goal is to have data visibility and use it for real-time security monitoring and analysis. Thus, you can warn of vulnerabilities that are occurring or those that could occur.

Why do we need a SIEM solution and what does it do?

If we talk about IT Security, time and the ability to respond early are important factors; since only those who recognize suspicious and unusual behavior patterns on the corporate network in time can react quickly and avoid further damage. This type of technology is focused to detect external and internal threats. Unlike a firewall, SIEM – Security Information and Event Management allows to detect and react in real time. It is worth mentioning that these technological solutions are focused on the prevention of threats not related to software vulnerabilities.

As we have previously stated, there is no debate about the fact that cybercrime and cyber attacks on any computer system is constantly increasing. This is one of the main reasons why network and system monitoring plays a crucial role in helping companies protect themselves, and this is where SIEMs are taking a leading role in increasing the degree of corporate security; along with the evolution and improvement over the years of the different methodologies and techniques related to these systems.

SIEM benefits include efficient incident response.

The different types of Companies use the SIEM systems for different purposes, so the benefits of these systems vary according to the organizations; Although we can highlight that all SIEM systems ingest, store, process and interpret large amounts of data, unifying the vision of the results.
