The cyber security landscape is constantly changing, with new threats means new approaches to secure your organisation. Keeping critical systems and safeguarding sensitive data has never been more important and this is why your organisation needs Security Information and Event Management (SIEM). In this article we discuss and introduce SIEM.

What is a SIEM?

SIEM is a centralised security centre that collects and monitors all the various activity across your estate. This data includes log data from devices, applications and systems. SIEMs generally normalise the data for easier analysis and then sift through this data in real-time to identify potential security threats.

Think of a SIEM as a centralised security command centre. It continuously collects log data – a record of activity – from various devices, applications and systems across your network. This data is then normalised (formatted consistently) for easier analysis. SIEMs can sift through massive amounts of information, identifying potential security threats in real-time.

What does a SIEM do?

4 key features of a SIEM:

  1. Aggregation: Collects data from across your IT estate including firewalls, intrusion detection systems, antivirus software, and more.
  2. Analysis: Analyses collected data for anomalies and suspicious activities, helping identify potential breaches or unauthorised access attempts.
  3. Security Alerts: Generates real-time alerts when security thresholds are breached, allowing security professionals to mitigate the risk.
  4. Compliance Reporting: Provides reports to demonstrate adherence to industry regulations and data privacy laws.

Why Does SIEM Matter?

  • Proactive threat detection: by analysing all the data available SIEMs can identify subtle patterns that might escape human analysis.
  • Improved response time: real-time and early detection alerts allow security teams to secure attacks quickly.
  • Improved security: By providing a consolidated security overview SIEM helps to identify and prioritise vulnerabilities.
  • Enhanced compliance: by generating audit logs and reports you can demonstrate meeting regulatory requirements.
