AI Enhanced Security Log Analysis Workflow for Effective Threat Detection

AI-Enhanced Security Log Analysis and Correlation

1. Data Collection

1.1 Identify Data Sources

Gather logs from various sources including:

• Firewalls
• Intrusion Detection Systems (IDS)
• Endpoint Detection and Response (EDR) tools
• Network Devices
• Application Logs

1.2 Implement Data Ingestion Tools

Utilize tools such as:

• Splunk: For log aggregation and indexing.
• Elastic Stack (ELK): For real-time search and analytics.

2. Data Preprocessing

2.1 Normalization

Standardize the format of logs to ensure consistency across different sources.

2.2 Data Enrichment

Enhance logs with contextual information using:

• Threat Intelligence Feeds: Integrate feeds from providers like Recorded Future or ThreatConnect.
• Geolocation Services: Utilize services to identify the geographical origin of IP addresses.

3. AI-Driven Analysis

3.1 Anomaly Detection

Implement machine learning algorithms to identify unusual patterns in log data. Tools include:

• IBM QRadar: Uses AI to detect anomalies in real-time.
• Darktrace: Employs unsupervised machine learning to identify threats.

3.2 Correlation of Events

Utilize correlation engines to identify relationships between disparate events. Examples include:

• ArcSight: Offers advanced correlation capabilities.
• LogRhythm: Provides AI-driven insights for incident detection.

4. Incident Response

4.1 Automated Alerts

Configure the system to generate alerts for detected threats using:

• Palo Alto Networks Cortex XSOAR: For automated incident response.

4.2 Investigation and Remediation

Facilitate investigations using:

• ServiceNow Security Incident Response: For managing and resolving incidents.
• CrowdStrike Falcon: For endpoint investigation and remediation.

5. Reporting and Continuous Improvement

5.1 Generate Reports

Create comprehensive reports on security incidents and trends using:

• Tableau: For visual analytics and reporting.
• Power BI: For business intelligence reporting.

5.2 Review and Optimize

Conduct regular reviews of the workflow and utilize feedback for continuous improvement.
