SIEM Use Cases

Identifying Insider Threats

According to the insider threat statistics provided by the Verizon Data Breach Investigations Report, three of the first five reasons for security incidents are related to an insider threat. Therefore, in addition to the measures taken within the framework of external threats, measures need to be taken for insider threats as well. Many organizations focus on the protection against external threats. However, adequate measures may not be taken against the threats originating from current and former employees, service contractors, or business partners that have daily access to their internal networks.

How can I identify and prevent the internal threats?

Detecting internal threats is challenging and complex. Logsign USO Platform tackles this by applying predefined correlation rules to indicators of malicious software and attack vectors. It analyzes this data with the Cyber Threat Intelligence (TI) service and shares the findings with IT managers through Dashboards, Alarms, Reports, and Incident Management/Response.

Detecting Compromised User Credentials

Detecting threats from within is challenging and complex. Logsign USO Platform identifies malicious software indicators and attack vectors by applying predefined correlation rules and analyzing data with the Cyber Threat Intelligence (CTI) service. The obtained data is then presented to IT administrators in the form of Dashboards, Alarms, Reports, and Incident Management/Response.


Suspicious Privilege Escalation

A privileged user account is a target with access priority. Logsign USO Platform can detect the users that increase their authority for critical systems.


Command and Control (C&C) Communication

Logsign USO Platform can associate the network traffic with the Threat Intelligence Service in order to discover the malware that communicates with external attackers. This points out a jeopardized user account.


Data Exfiltration

You can track lateral movements with Logsign's Correlation Library, Cyber Threat Intelligence (CTI) service, and User Entity and Behavior Analysis (UEBA) through Logsign USO Platform to analyze seemingly unrelated events such as the insertion of USB disk drives, process information, personal email services, cloud storage services, or high data traffic over the Internet and local network.


Rapid Encryption

It can detect the encryption of the data in the user systems. These abnormal incidents on the user data may be ransomware attacks.


Proactive Threat-Hunting Capabilities

It can be used for proactive threat-hunting activities. Security analysts can leverage advanced analytical capabilities to search for indicators of compromise (IoCs) and conduct detailed investigations into suspicious events or entities. Organizations actively seeking threats can identify and mitigate potential security risks before they cause significant harm.


Efficient Incident Response Automation

By centralizing and correlating security event data, it streamlines efficient incident response workflows. It integrates with ticketing systems and other incident response tools, enabling security teams to automate the incident response process. Logsign can trigger automated actions such as quarantining a compromised host or blocking malicious IP, username, URL, domain, or hash information, reducing response times and minimizing the impact of security incidents.
