Please note that the suggested logging levels may vary depending on the specific requirements of your organization and the importance of different log sources. It’s important to customize these logging levels based on your environment and the value they provide to your SIEM.
Purpose-Driven and Customized Correlation Rules:Correlating events from multiple sources lies at the heart of SIEM functionality. To optimize efficiency and derive maximum value from your SIEM investment, it’s crucial to carefully choose and implement correlation rules that align with your specific environment. Follow these steps to effectively manage correlation rules:
- Enable relevant correlation rules and fine-tune them based on observed events.
- Stabilize the correlation rules and enable response actions.
- Expand the range of enabled correlation rules based on high-level categories.
- Develop custom correlation rules to address specific use cases.
Building Threat Intelligence:SIEM systems typically include built-in threat intelligence feeds. However, cross-checking these feeds with third-party sources enhances accuracy and reduces false positives. Configure correlation rules related to threat intelligence feeds to utilize multiple sources for reliable verdicts.
Customized Dashboards and Reports:
Creating meaningful and actionable dashboards and reports is crucial for identifying abnormal patterns and events not covered by correlation rules. Customize default reports and dashboards to address specific needs and highlight relevant information. For example, focus on top users accessing malicious domains, authentication failures by executive management, or suspicious emails from executive management mailboxes.
By incorporating these recommendations, your SIEM operational strategy can become more organized, concise, and actionable. Additionally, consider including visual aids, referencing external sources, and providing additional resources to enhance the article’s appeal and credibility.
Conclusion:A well-defined SIEM operational strategy is essential for maximizing the effectiveness of your security operations. By implementing selective log collection, purpose-driven correlation rules, robust threat intelligence, and customized dashboards, your organization can harness the full potential of SIEM.
