Organizations, businesses, governments and individuals are using the internet today more than ever before. With each new year, there are more applications, devices, systems and equipment that are being used everywhere in the world. As the number of devices grows, so does the number of security events that are being logged, which can make it very difficult to recognize attacks and other damaging processes. This is why many companies are now using SIEM, or Security Information and Event Management solutions as part of their cybersecurity strategy.

What are SIEM solutions?
A SIEM program collects, analyses and stores information about security events. The purpose of SIEM solutions is to provide compliance to organizations, detect outside threats, simplify incident reporting and management, etc. When an organization uses a SIEM, it allows its IT department to identify threats and mitigate attacks before or while they are happening, lowering cybersecurity risks overall.
How does a SIEM operate?
The principle of operation for a SIEM is very simple: first, it obtains information about security events from various devices, systems and networks, then it normalizes and compiles the data. Next, this data is analyzed systematically to identify security threats. Finally, security breaches are pinpointed by the system and the IT staff has the opportunity to investigate them.
Advantages of using SIEM solutions
First of all, a SIEM provides an organized, centralized look into security incidents and events, which makes it much easier for the IT staff to notice irregularities and identify attacks. Secondly, many modern SIEM solutions have a dashboard where the IT staff can receive notifications about certain predefined security events. Some SIEM solutions even use artificial intelligence to identify threats and alert the staff about them. Finally, organizations and companies in some sectors of business, such as finance, medicine, etc. are required to utilize a SIEM solution as part of their cybersecurity strategy. Therefore, using a SIEM solution ensures compliance.
