What is a SIEM?

In a nutshell:
SIEM is essentially the combined power of two security systems. It is a software solution combining the functionalities of Security Information Management (SIM) and Security Events Management (SEM) into one primary security management system. Want to go a bit more in-depth? Keep reading.
SIEM is now a billion industry, yet only 21.9% of companies are benefiting from the tools.

What is SIEM?

How does it work?

There are generally three main steps which SIEM tools follow.

Step 1 – Collect relevant data from various sources

SIEM collects vast amounts of data ranging across your entire infrastructure, generated from devices, servers, applications and more, to assemble it in one centralised platform. This data is then ranked into categories such as malware activities, failed logins attempts, and other activity that is deemed suspicious.

Step 2 – Analyse data to identify deviations and detect threats

This collected data is then analysed, allowing the software to identify any unconventional activity and produce alerts to signal a potential security risk to your business. Alerts can be set as high or low priority, based on analytics using a set of rules outlined by your organisation. For example, a user generating 10 failed login attempts within 20 minutes would be classed as a low priority risk as it is likely that the user had forgotten their login details. However, 100 failed login attempts within 5 minutes suggests an attack and would consequently be flagged as a higher risk to the business.

Step 3 – Isolate security breaches and take the appropriate action

By pinpointing and prioritising these security risks, your organisation is enabled to have complete visibility over data security breaches, allowing your IT team to investigate abnormalities, rapidly respond to risks, and take the appropriate action needed to safeguard your organisation.

Benefits of using SIEM

If you want complete control and visibility over your business’s data and security logs, then a SIEM solution is critical. Not only do SIEM technologies make security management easier for organisations through filtering and prioritising vast amounts of security data, it also allows your business to detect threats that may have otherwise slipped under the radar through providing a holistic view of your security environment.

By reducing the time is takes to identify significant threats, potential damage is mitigated, whilst detailed forensic reports are generated in the case that there is a security incident. In essence, the benefits of implementing a SIEM solution will result in improved visibility over your security posture and 24/7 protection.
