Co-Managed SIEM – Level 1- and Level 2-Analysis

Within the scope of security monitoring, SECUINFRA Cyber Defense experts not only take over the sustained analysis of IT security incidents, but also carry out a precise qualification of the incidents and provide suggestions for countermeasures.

A SIEM product only sounds the alarm

No matter which SIEM product you use, you will receive lots of more or less qualified SIEM alerts. These still need to be analyzed and evaluated by cyber defense experts in order to assess the impact on your corporate security and initiate countermeasures.

SECUINFRA Co-Managed SIEM can do more!

Our cyber defense experts always keep track of the current threat situation and continuously analyze anomalies (SIEM alerts). They escalate security breaches to the incident response team, including an assessment and clear recommendations for countermeasures.

Co-Managed SIEM – SIEM Content-Development

In the area of SIEM content development, SECUINFRA has continuously invested and developed unprecedented concepts, methods and techniques since 2010.

Starting with our “Status Based SIEM” approach, which has enabled SECUINFRA customers to keep track of active cyberattacks and compliance violations, to an “Application Security Cockpit” for monitoring critical applications, to our ever-growing “End-to-End SIEM Use-Case Library”, SECUINFRA has created globally unique SIEM content.

In addition to their own experience, our SIEM content developers draw on the concepts, methods and techniques developed by SECUINFRA on a daily basis and continue to develop them further.

The SIEM use case designer takes your requirements for the SIEM and checks whether and how your requirements can be implemented. Furthermore, he calculates the effort and coordinates the implementation in the areas of log policy development, connector development and use case development. Our SIEM use case designers draw on years of experience in the field of SIEM and can also support you in defining your requirements.

Once the log data is available in the SIEM in the appropriate quality, our SIEM expert brings “intelligence” into the SIEM. To do this, he defines and implements the algorithms that are to be used to detect irregularities. In doing so, he draws on our internal end-to-end use case database. If we do not receive any deviating strict specifications for the development methodology or naming convention, we use our SIEM use case framework.

Our Connector Developer is responsible for connecting log sources to the SIEM. If log sources are not supported by default, we develop appropriate connectors for you. The development of these connectors requires specialized knowledge and, above all, a lot of experience. Since some of our SIEM experts deal with connector development on an almost daily basis, they are able to deliver results quickly and efficiently.

In the Log Policy Development area, we support you in defining the right log policy per log source type. These form the basis of every SIEM. Only if the necessary data is generated with the right content, irregularities can be detected. We draw on several years of experience from numerous projects.
