By, Jack Wong

SIEM in cyber security refers to Security information and event management (SIEM) technology that supports threat detection compliance and security incident management through the collection and analysis of real-time and historical security events, as well as a wide variety of other events and contextual data sources. The core capabilities include a broad scope of log event collection and management, the ability to analyse log events and other data across disparate sources and operational capabilities such as incident management, dashboards and reporting.

In short, SIEM is a security solution that helps organisations recognise potential security threats and vulnerabilities before they have a chance to disrupt business operations.

Recently, SIEM has evolved into something more than log management technology. Because of artificial intelligence and machine learning capabilities, SIEM now provides advanced user and entity behaviour analytics (UEBA).

How does SIEM works?

They are combining security information management with security event management. SIEM’s overarching principle is to collect relevant data from sources, identify deviations from the norm and take appropriate action. For instance, a SIEM system will log additional information, create an alert and notice different security controls to block suspicious progress when a potential issue is detected.

What are the key features of SIEM in cyber security?

SIEM technology helps security analysts see across their enterprise IT environment and detect threats that evade other means of detection. The SIEM solution will be able to help security staff do their jobs better and can help an organisation solve three significant security challenges:

  • SIEMs alert you when suspicious things happen
  • Alerts on the threat in real time - really help us minimise the potential damage
  • Compliance reporting

The benefit of SIEM in cyber security

The SIEM solution will solve many major security challenges:

  • Data aggregation and visibility: Not only collect and store the data in your IT environment in a centralised location, but SIEM also provides you with an easier way to compare, analyse and correlate data
  • Real-time threat recognition: Helping to improve security posture by reducing the lead time to identify potential network threats with SIEM real-time monitoring solution
  • Detecting potential threats: SIEM solutions can deal with threats like social engineering attacks using artificial intelligence technology.
  • Assessing and Reporting on Compliance: SIEM solutions dramatically reduce the resource cost required to manage this process by providing real-time audits and on-demand reporting of regulatory compliance whenever needed.
