I'm Being Attacked, Now What?
Published Jun 08 2022 09:42 AM 9,909 Views

There is no shortage of incident response frameworks in the security industry. While the processes may vary, there is relatively universal agreement on requirements to remediate an incident and conduct lessons learned. Remediation falls towards the end of the incident response cycle because security teams must fully analyze the incident to understand several dynamics:


  • Who is the attacker?
  • When did the incident occur?
  • Which user, asset, or data are being targeted?
  • Which attack techniques were leveraged?
  • Which of our defenses detected it?
  • Is this the full scope of the compromise, or are more factors involved?

Security teams respond after understanding these and several organizationally aligned information requirements. The incident is closed when there is confidence the attacker was expelled from the environment and respective actions completed. The difference between a young Security Operations Center (SOC) and a mature one often lies in the way incident response teams conducts lessons learned. This process evolves from a “rinse and repeat” type approach to proactive threat modeling. Proactive threat modeling is critical to understanding where the attacker maneuvered through a network. The MITRE ATT&CK® framework allows security teams to understand the methods attackers employ against networks. Recently MITRE Engenuity published the NIST SP 800-53 Controls to ATT&CK Mappings which provides an actionable approach to implementing defenses based in the NIST SP 800-53 controls framework.


Microsoft Sentinel: Threat Analysis & Response SolutionMicrosoft Sentinel: Threat Analysis & Response Solution


The Microsoft Sentinel: Threat Analysis & Response Solution takes this a step further with (2) new Workbooks designed to support development of threat hunting programs and dynamic threat modeling designed to identify, respond, harden, and remediate against threats. Microsoft Defender for Cloud is a Cloud Workload Protection Platform (CWPP) and Cloud Security Posture Management (CSPM) which provides powerful coupling with Microsoft Sentinel. Where Microsoft Sentinel provides incident response capabilities, Microsoft Defender for Cloud provides remediation actions aligned to respective regulatory compliance initiatives. Once the incident is fully remediated and cloud weaknesses are addressed there is also the ability to evaluate analytics coverage with the Microsoft Sentinel MITRE ATT&CK® blade. Check out the demo to see how.

Solution Overview

Threat Analysis & Response Workbook

Designed by the Microsoft Threat Intelligence Center, the Threat Analysis & Response Workbook provides the foundation for building threat hunting programs. This workbook features recommended steps for getting started including resources for deploying analytics rules and hunting queries. Data Source Statistics provides an overview of which logs are ingested from respective sources which provides a starting point for determining utility of respective analytics rules. The Microsoft Sentinel GitHub section provides an overview of available analytics by alignment to respective tactics/techniques. MITRE ATT&CK Navigator Heatmap provides an assessment of coverage by tactic and technique areas which is valuable for evaluating the efficiency of organizational threat hunting programs.

Dynamic Threat Analysis & Response Workbook

The Dynamic Threat Analysis & Response Workbook dynamically assesses attacks to your on-premises, cloud, and multi-cloud workloads. Attackers are categorized by the MITRE ATT&CK for Cloud Matrix and evaluated against Microsoft Sentinel observed Analytics and Incidents. This provides pivots to evaluate attacks against specific users, assets, attacking IPs, countries, assigned analyst, and detecting product. Each tactic provides a respective control area comprised of technique control cards.

Technique Control Cards provide details of establishing coverage, evaluation of observed attacks, and defense recommendations aligned to NIST SP 800-53 controls. Observed attacks are addressed via Microsoft Sentinel Incidents for Investigation, Playbooks for Response, MITRE ATT&CK blade for Coverage, and Microsoft Defender for Cloud for Remediations.

Microsoft Sentinel: MITRE ATT&CK Blade

MITRE ATT&CK is a publicly accessible knowledge base of tactics and techniques that are commonly used by attackers and is created and maintained by observing real-world observations. Many organizations use the MITRE ATT&CK knowledge base to develop specific threat models and methodologies that are used to verify security status in their environments. Microsoft Sentinel analyzes ingested data, not only to detect threats and help you investigate, but also to visualize the nature and coverage of your organization's security status.

This solution demonstrates best practice guidance, but Microsoft does not guarantee nor imply compliance. All requirements, tactics, validations, and controls are governed by respective organizations. This solution provides visibility and situational awareness for security capabilities delivered with Microsoft technologies in predominantly cloud-based environments. Customer experience will vary by user and some panels may require additional configurations for operation. Recommendations do not imply coverage of respective controls as they are often one of several courses of action for approaching requirements which is unique to each customer. Recommendations should be considered a starting point for planning full or partial coverage of respective requirements.
