SIEM systems

What is SIEM?

Tietoturva on erittäin tärkeä asia nykypäivänä.

SIEM, or Security Information and Event Management, is a cybersecurity management system that provides a comprehensive way to manage and monitor an organization's security events in real-time. SIEM systems collect, analyze, and interpret security data from various sources, such as log files, system events, network traffic, and user activities. These systems help organizations detect and respond to security incidents and threats quickly.

Examples of SIEM systems

Splunk: Splunk is one of the most well-known and widely used SIEM solutions. It provides a versatile platform for security monitoring, analysis, and response as well as integration with other security systems.

ELK Stack (Elasticsearch, Logstash, Kibana): ELK Stack is an open-source SIEM solution based on the Elasticsearch database, Logstash security data collector, and Kibana visualization tool. It provides a scalable and flexible platform for cybersecurity management.

IBM QRadar: QRadar is a SIEM solution offered by IBM, which provides a wide range of features for security management, including user activity analysis, network traffic monitoring, and automated response.

LogRhythm: LogRhythm is another well-known SIEM solution that provides a comprehensive range of cybersecurity management features, such as event correlation, user activity monitoring, and automated alert management.

In addition, there are several other SIEM systems for different-sized organizations and different needs. The choice is influenced by the organization's needs, budget, and technical requirements. In the following module, we will practice using a SIEM system built on top of the ELK stack (ElasticSearch, LogStash, Kibana) platform.
