SIEM Deployments
We implement SIEM systems - Security Information Event Management
What is SIEM?
Security Information and Event Management (SIEM) systems is another security line whose main task is to analyze and correlate logs from various computer devices and systems.
SIEM are products and services that combine security information management (SIM) and security event management (SEM - Security Event Management). SIEM class systems provide real-time analysis of security alerts generated by applications and network hardware , logged or sent in online messages.
SIEM ingredients?
SIEM is a set of applications that:
- monitor the entire network infrastructure and applications, with particular emphasis on server systems
- notify about events identified as security anomalies,
- collect and aggregate information from different logs,
- are available as agents installed on servers, workstations and remotely read information from other devices,
- are usually included in one coherent product.
How does SIEM work?
SIEM can be configured as a central log server. This configuration guarantees the highest efficiency in the analysis of detected events.

As a result of SIEM, Administrators no longer have to view logs manually. They receive processed information about threats and risk estimation related to detected irregularities.

Aggregates data
SIEM combines data from various sources, network switches, firewalls, routers, servers, databases, web servers, client stations and other applications so that all logs are completely and intact in one central place.
Correlates data
As a result of the correlation, the relations between events occurring in the logs of various devices and applications are analyzed. Correlation is based on rules that automate the comparison process and present the end result in the form of an alert.
Notifies
As a result of automated analysis of correlated data, notifications are generated when a threat or anomaly is found. Alerts can be forwarded to many people in a different scope and through different channels (SMS, e-mail, network message).
Monitors
SIEM sends the identified events in real time to the SOC (Security Operation Center), where analysts have the opportunity to take action without undue delay.
It stores data
Thanks to high retention, it is possible to store logs for a very long time (or even indefinitely) in order to find harmful activities in the IT systems in a long unit of time.
