SIEM
Centralise, correlate and analyse data across the IT network.
Data are the basis for security
A modern SIEM requires three core functions – data collection, analysis and response – to provide the security required in today’s hybrid and multicloud environments. A SIEM’s job is to collect data across your network (data collection), identify malicious behaviour (analysis) and send alerts to security and IT teams to give them the insight they need to respond before problems become serious and information (response). If compliance reports are an important factor, the SIEM should also be able to help with dashboards and ensure that security policies are enforced.
Advantages of SIEM
It correlates and analyses data from different sources in real time
It collects and analyses data from all sources in real time
The SIEM system collects and correlates log data from different sources to ensure a holistic and cross-component real-time analysis. The more data a company can provide to its SIEM software, the more insight analysts have into activities and the more effectively they can detect and respond to threats.
It reduces the need for cybersecurity personnel
Today's security teams are increasingly pressed for time, so improved automation frees analysts from manual tasks. It allows them to better coordinate responses to threats. The best modern SIEM solutions use unsupervised machine learning to free up overworked security analysts. This is done through ML-powered anomaly detection and Automated Threat Response.
It makes security analysts more productive from day one
Once logs are collected, the out-of-the-box detections can be used which, according to the current standard, detect a large number of threats and report them according to priority. Additional custom detections can be implemented to monitor and report on specific customer policies.
SIEM for Cyber Monitoring
Security Information and Event Management (SIEM) is an active cyber security monitoring based on log data. Here, the data from the different sources are correlated to obtain a holistic view of the entire IT infrastructure and its security. Now cross-component and cross-product checks can be carried out, which would not be possible without correlations of the different sources. The already existing standard monitoring provide a good basis for detecting advanced threat patterns and alerting the respective responsible parties.
In addition, environment-specific monitoring can be set up to provide a detailed security overview. There are very few situations where only one surveillance triggers an alarm at a time. Therefore, alerts will be categorised according to their criticality and made available to those responsible for further analysis.
Now the analyst can analyse the indicators behind the alarms and take appropriate action.

Benefit:
Only cyber security monitoring can prove whether the security measures taken and integrated security applications serve their purpose in the constantly changing IT world.
This makes the use of a SIEM solution indispensable in order to detect current threats and to take measures if necessary.
