SOAR (Security Orchestration, Automation & Response)

What is SOAR?

• Definition: Connecting and integrating security tools and systems to automate security workflows.
• Purpose: Improve efficiency, reduce response times, and enhance security operations.
• Key Benefits:
  • Automation: Reduces manual effort and human error.
  • Orchestration: Streamlines security processes.
  • Incident Response: Accelerates incident response and remediation.
  • Threat Intelligence: Integrates threat intelligence for better context and decision-making.
  • Reporting: Standardizes and automates reporting.

Typical SOAR Workflow

1. Detection: Security events are detected by integrated tools (e.g., SIEM, NIDS).
2. Enrichment: Threat intelligence is gathered to provide context about the event.
3. Triage: The SOAR analyzes the event's severity and potential impact.
4. Response: Automated actions are taken to contain the threat (e.g., isolate systems, block IPs).
5. Remediation: Root cause analysis is performed, and remediation actions are automated (e.g., patching, vulnerability upgrades).
6. Reporting: Standardized reports are generated for communication and analysis.

SOAR vs. SIEM

• SOAR:
  • Focuses on automation and orchestration.
  • Uses playbooks and runbooks to automate responses.
  • Reduces manual effort and improves response times.
• SIEM (Security Information and Event Management):
  • Collects and analyzes security logs and events from various sources.
  • Provides centralized visibility and alerting.
  • Supports threat detection and investigation.
• Relationship: SOAR complements SIEM by automating responses to alerts generated by the SIEM.

SOAR Playbook Examples

• Email Analysis and Case Management: Automates the analysis of email files, performs malware analysis, extracts indicators of compromise (IOCs), and updates case management systems.
• CVE Analysis and Patching: Automates the process of analyzing CVEs, assessing risk, creating patching tickets, testing patches, and deploying them to production.

SOAR Workflow for Patching

1. Monitor Advisories: The SOAR monitors security advisories and extracts CVE information.
2. Check Patching History: Queries the internal patch management system to see if the CVE has already been addressed.
3. Assess Applicability: Determines if the CVE affects any assets within the organization.
4. Create Tracking Ticket: If the CVE is applicable, a ticket is created and assigned to an analyst.
5. Compile Asset List: The SOAR identifies assets that require patching.
6. Check for Patch Availability: Queries the patch management system for the patch. If unavailable, the system is updated with the latest patch information.
7. Test Patch: The SOAR creates virtual test environments, applies the patch, and logs test results.
8. Update Ticket: The CVE ticket is updated with the patch testing outcomes.
9. Deploy Patch: The patch is deployed to production assets, and the analyst verifies the rollout.
10. Vulnerability Scan: A scan is conducted to ensure the vulnerability is remediated.
11. Close Ticket: The CVE ticket is closed, and the patch management system is updated.

Insufficient Credential Hygiene

• Risks: Insecurely stored or managed credentials can lead to unauthorized access, data breaches, and lateral movement within a network.
• Recommendations:
  1. Least privilege: Grant only necessary permissions.
  2. Avoid credential sharing: Maintain accountability and simplify management.
  3. Temporary credentials: Use short-lived credentials whenever possible.
  4. Rotate credentials: Regularly change static credentials.
  5. Detect secrets in code: Use tools to scan for exposed credentials in code repositories.
  6. Prevent console output of secrets: Mask or redact sensitive information in logs and outputs.
  7. Remove secrets from artifacts: Ensure credentials are not stored in container images, binaries, or other artifacts.
  8. Use environment variables: Store sensitive information in environment variables instead of hardcoding it.
