Attack disruption is a powerful Microsoft Defender XDR capability that automatically contains ongoing attacks, limiting their impact while security analysts investigate. When ransomware or Business Email Compromise (BEC) incidents trigger attack disruption, specific investigation procedures should be followed.

For ransomware incidents, analysts should first review the attack disruption actions taken, such as device isolation or user account suspension. Examine the attack story timeline to understand the initial access vector, whether through phishing, exploited vulnerabilities, or compromised credentials. Identify all affected assets by reviewing the incident graph showing lateral movement patterns. Analyze which files were encrypted and check for data exfiltration indicators. Review the automatic evidence collection including process trees, file hashes, and network connections. Validate that containment actions are sufficient and determine if additional manual remediation is required.

For BEC incidents, attack disruption typically suspends compromised user accounts to prevent further malicious email activity. Investigators should examine the email timeline to identify phishing messages that led to credential theft. Review sign-in logs for suspicious authentication patterns, including unusual locations or devices. Check for inbox rules created by attackers to hide their activities. Analyze any financial fraud attempts, such as wire transfer requests or invoice manipulation. Examine OAuth application consents that may have been granted during the compromise.

In both scenarios, analysts should document the attack chain thoroughly, correlate alerts across endpoints, identities, and cloud apps, and assess the full scope of compromise. After investigation, review whether automatic containment actions should be maintained or modified. Coordinate with stakeholders for business continuity decisions. Finally, generate detailed incident reports documenting findings, timeline, affected assets, and remediation steps taken. Understanding the attack disruption feature allows analysts to respond more effectively while automated protections buy valuable investigation time.

When investigating compromised entities from Microsoft Purview Data Loss Prevention (DLP) policies within Microsoft Sentinel, security analysts must follow a systematic approach to identify and remediate potential data breaches. Purview DLP policies help organizations protect sensitive information by detecting and preventing unauthorized sharing or access to confidential data.

Best practices include regularly reviewing user access, removing permissions for departing employees promptly, and implementing conditional access policies through Microsoft Entra ID. Organizations should document their permission structure and establish clear procedures for requesting and approving access changes. This comprehensive approach to permission management helps maintain security posture while enabling analysts to leverage Security Copilot capabilities for incident response and threat investigation.

Security Copilot capacity and cost monitoring is essential for organizations utilizing Microsoft's AI-powered security assistant. Security Copilot operates on a consumption-based pricing model using Security Compute Units (SCUs), which measure the computational resources consumed during security operations tasks.

Capacity management involves provisioning SCUs based on organizational needs. Administrators must assess workload requirements, considering factors like the number of security analysts, frequency of investigations, and complexity of queries. SCUs can be provisioned in increments, allowing flexible scaling based on demand patterns.

To monitor capacity utilization, security teams should access the Microsoft Defender portal or Azure portal where usage metrics are displayed. Key metrics include SCU consumption rates, peak usage periods, and trending data over time. Understanding these patterns helps organizations optimize their provisioning strategy and avoid service disruptions during critical security incidents.

Cost management requires establishing budgets and monitoring actual spend against allocated resources. Organizations should implement alerts when consumption approaches threshold limits. Azure Cost Management provides detailed breakdowns of Security Copilot expenses, enabling finance and security teams to track return on investment.

Best practices for managing capacity and cost include:

1. Establishing baseline usage patterns during initial deployment phases
2. Creating governance policies defining approved use cases and user groups
3. Implementing regular reviews of consumption reports to identify optimization opportunities
4. Training analysts on efficient query formulation to maximize value per SCU consumed
5. Setting up automated alerts for unusual consumption spikes that might indicate misuse or inefficient workflows

Organizations should balance cost efficiency with operational readiness, ensuring sufficient capacity exists during security incidents when rapid investigation capabilities become critical. Regular capacity planning sessions help align Security Copilot resources with evolving security operations requirements while maintaining budget compliance across the organization.

Security Copilot is an AI-powered security tool that helps Security Operations Analysts identify threats and risks more efficiently within their organization's environment. This capability transforms how analysts approach incident response by leveraging natural language processing and machine learning to accelerate threat detection and analysis.

When using Security Copilot to identify threats and risks, analysts can submit queries in natural language to investigate suspicious activities, analyze security alerts, and correlate data across multiple security solutions. The tool integrates with Microsoft Sentinel, Microsoft Defender XDR, and other security platforms to provide comprehensive threat intelligence.

Key capabilities include analyzing incident summaries where Security Copilot can process complex security incidents and provide clear explanations of what occurred, which systems were affected, and potential attack vectors. Analysts can ask questions like "What are the indicators of compromise in this incident?" or "Show me related threats across my environment."

Threat intelligence enrichment allows Security Copilot to pull relevant threat intelligence data, helping analysts understand the context of detected threats, including known attacker techniques, malware families, and recommended remediation steps. This contextual information enables faster and more informed decision-making during incident triage.

Risk assessment becomes more streamlined as Security Copilot can evaluate the potential impact of identified threats on business operations. It helps prioritize which incidents require urgent attention based on severity, affected assets, and organizational risk tolerance.

The tool also assists in hunting for threats by generating KQL queries based on analyst descriptions, enabling proactive searches for suspicious patterns or behaviors that might indicate undetected compromises. This capability reduces the expertise barrier for threat hunting activities.

By combining these features, Security Copilot enables analysts to reduce mean time to detect and respond to threats while maintaining thorough documentation of their investigation processes for compliance and future reference purposes.

Security Copilot is an AI-powered tool integrated into Microsoft Defender XDR that enhances incident investigation capabilities for security analysts. When investigating incidents, Security Copilot provides natural language interaction to help analysts understand and respond to threats more effectively.

To investigate incidents using Security Copilot, analysts can access the tool through the Microsoft Defender portal. The Copilot sidebar appears when viewing incident details, allowing analysts to ask questions about the incident in plain language. For example, analysts can ask 'What happened in this incident?' or 'Which devices are affected?' and receive comprehensive summaries.

Key capabilities include incident summarization, where Copilot analyzes alerts, entities, and evidence to provide a consolidated view of what occurred. This helps analysts quickly understand the scope and severity of an incident. The tool can also perform script analysis, examining PowerShell, batch files, or other scripts found during investigation to determine if they contain malicious code.

Guided response is another valuable feature where Copilot suggests remediation actions based on the incident context. These recommendations help analysts take appropriate steps to contain and resolve threats. Additionally, Copilot can generate reports summarizing investigation findings, which is useful for documentation and stakeholder communication.

Analysts can use natural language queries to explore entity relationships, understand attack timelines, and identify indicators of compromise. The tool correlates data across multiple Microsoft security products, providing a unified investigation experience.

Security Copilot also assists with threat intelligence by providing context about known threat actors, malware families, and attack techniques relevant to the incident. This contextual information helps analysts assess the sophistication and potential impact of attacks.

By leveraging these capabilities, security operations teams can reduce investigation time, improve accuracy in threat assessment, and respond to incidents more efficiently while maintaining comprehensive documentation of their analysis.
