4_3_2 Section 4 – Operations and Incident Response - 4.3 – Investigations- SIEM Dashboards

Primary Function of SIEM System

• Centralized monitoring and analysis of security events and incidents.
• Combines security information and event management for better threat detection.

Types of Data Gathered by SIEM

• Log data from various sources such as firewalls, intrusion detection systems, and servers.
• Network traffic information to monitor communications across the network.

Purpose of Long-Term Log Storage

• Facilitates compliance with regulations that require data retention.
• Enables historical analysis to identify patterns and detect anomalies over time.

Incident Response Facilitation

• Automates alerts and notifications for unusual activities or threats.
• Provides forensic data to aid in identifying the scope and impact of incidents.

Benefit of Consolidating Log Data

• Simplifies monitoring and reporting through a single interface.
• Enhances the ability to correlate events from multiple sources for improved insights.

Key Advantage for Security Event Analysis

• Early detection of potential threats through real-time analysis of security data.
• Improved situational awareness by aggregating security information.

Purpose of Using SIEM System

• Enhances overall security posture by providing tools for detection, analysis, and response to threats.
• Aids in compliance with industry standards and security frameworks.

Benefit of Parsing Data

• Improves the ability to identify and prioritize security events based on severity.
• Leads to more efficient data handling and reduces noise in security alerts.

Insights from Long-Term Log Data Analysis

• Detection of emerging threats by studying historical trends.
• Identification of recurring issues that require remediation or adjustment to security policies.

Advantage of Correlating Different Data Types

• Facilitates the identification of complex attack patterns that may not be evident in isolated data sets.
• Enhances threat intelligence by connecting related events across diverse logs.

Purpose of Drilling Down into Raw Data

• Enables detailed investigation of specific incidents or anomalies.
• Provides context for alerts, allowing security teams to understand the significance of events.

Benefit of a Large Database of Log Entries

• Increases the likelihood of discovering long-term patterns or trends in security behavior.
• Supports enhanced forensic analysis and threat hunting initiatives.

Actions with SIEM Search Results

• Investigate specific incidents involved in security breaches.
• Generate reports for compliance and audit purposes based on detailed findings.

Purpose of the Left Side of the SIEM Screen

• Displays key metrics, alerts, and categorized event logs for easy navigation.
• Helps users quickly access various sections for monitoring security in real time.

Insights from Analyzing Search Results

• Identification of anomalies and unusual patterns that warrant further investigation.
• Correlation of events to develop a clearer understanding of potential threats.

Advantage of Using SIEM with Intelligence

• Integrates threat intelligence feeds to enhance detection capabilities.
• Increases accuracy of alerts by correlating events with known threat indicators.
