Today, the flow of data and information is constantly increasing in the digital world. Companies, organizations and even individuals often face cyber threats while managing this data flow. Various measures are taken to combat these threats and ensure their security. One of these measures is Security Information and Event Management (SIEM) systems. SIEM is an approach that includes many components used to protect the IT security of an organization or institution. One of these components is the log correlation service.
What is SIEM & Log Correlation Service?
SIEM log correlation service is the process of collecting, analyzing and correlating log records of various events and activities that occur in organizations. This service brings together log data from different systems and transforms it into meaningful information, allowing the security team to detect and respond to threats.
WHY IS IT NECESSARY?
Threat Detection and Prevention
By bringing together log data from different systems, the SIEM log correlation service provides the ability to detect and respond quickly to potential threats. For example, it can analyze log data to detect when an attacker is trying to break into the network or when an internal user is performing an unauthorized action.
Event Attribution
Correlating log data from different systems allows much more meaning to be drawn from the information received in isolation. For example, a log showing that a user has successfully logged into the network can be correlated with another log showing that the same user has subsequently performed an unauthorized action to provide a more comprehensive picture.
Alerts and Notifications
SIEM log correlation service analyzes log data according to defined rules, identifies potential threats and sends alerts to the security team. These alerts ensure a quick response to potential threats.
Incident Investigation and Analysis
The SIEM log correlation service can also be used to analyze past events and identify patterns of previous attacks. This allows preventive measures to be taken to prevent future attacks.
