Challenge :
The telecommunications provider needed a robust cybersecurity solution capable of handling large volumes of security events and incidents in real-time while also enabling efficient storage and querying of historical data.
Solution :
We implemented a hybrid Security Information and Event Management (SIEM) system utilizing both on-premises and cloud-based architectures. The key components of our solution included
Data Sources:
Logs were collected from various sources, including applications, network devices, and servers, ensuring comprehensive coverage of the telecommunications provider’s infrastructure.
Log Collection:
We employed agents like File beat, Logstash, and Fluentd to gather logs from all data sources and send them to a centralized log aggregator for initial staging.
Data Ingestion:
Using Snow pipe and custom ingestion scripts, logs were efficiently ingested into Snowflake for long-term storage and analysis.
Snowflake:
Snowflake served as the primary storage solution for raw and processed log data. Its scalable architecture allowed us to handle large volumes of data seamlessly.
Data Processing:
Snowflake tasks and stored procedures were utilized to transform and enrich log data, making it ready for advanced analysis and threat detection.
SIEM Application:
A custom SIEM application was integrated with Snowflake, providing real-time monitoring, alerting, and incident management capabilities. This integration enabled the telecommunications provider to respond promptly to security threats.
Visualization and Reporting:
BI tools such as Tableau and PowerBI were used to create dashboards and reports, leveraging Snowflake’s powerful querying capabilities for both real-time and historical data.
Outcome:
By leveraging a hybrid architecture, we ensured that real-time data was stored and processed on-premises for immediate action, while archival data and large-scale queries were handled efficiently in Snowflake. This approach provided the telecommunications provider with a comprehensive cybersecurity solution, enhancing their ability to detect, respond to, and manage security incidents effectively.
