Whether it’s a data breach, malware attack or targeted ransomware campaign, more and more organisations are falling victim to security incidents in 2023.

The UK government’s 2023 cyber security breaches survey estimated that 2.39 million instances of cybercrime have occurred since April 2022, with hackers targeting a shocking 3 per cent of all British businesses in the last 12 months alone.

What is a SIEM Tool?

As cyber attacks spike around the world, Security Information and Event Management (SIEM) tools are crucial to protecting your business from downtime and crashes when incidents strike.

A SIEM tool helps organisations collect, aggregate, and analyze security data from a variety of sources, including network devices, security appliances, and applications. They use this data to identify potential security threats and incidents and then generate alerts and reports.

SIEM can instantly alert your security team in the event of an attack, ensure they have everything they need to monitor threats, deal with problematic security events, and analyse essential data.

SIEM tools typically include the following features:

  • Log collection and aggregation - SIEM tools collect logs from a variety of sources and store them in a central location. This allows security teams to easily search and analyze all of their security data in one place.
  • Event correlation - SIEM tools correlate events from different sources to identify patterns and trends that may indicate a security threat. For example, a SIEM tool might correlate a failed login attempt from one source with a successful login attempt from another source to identify a potential brute-force attack.
  • Security alerts - SIEM tools generate alerts when they detect suspicious activity. This allows security teams to quickly investigate and respond to potential threats.
  • Reporting - SIEM tools provide reports on security activity and trends. This information can be used to improve security posture and to comply with regulatory requirements.
