2. Our Approach

[Tool Selection] → [Deployment & Configuration] → [Baseline Profiling] → [Real-Time Monitoring] → [Alert Triage & Response] → [Investigation & Containment] → [Reporting & Improvement]

3. Methodology

Assessment & Planning: Understand the client’s existing infrastructure and identify the most suitable EDR platform(s) for deployment (e.g., CrowdStrike, SentinelOne, Microsoft Defender).
Deployment & Configuration: Roll out EDR agents across endpoints, configure detection rules, logging, and integrations with SOC/SIEM platforms.
Baseline & Behavior Profiling: Establish a normal activity baseline across endpoints to reduce false positives.
Monitoring & Detection: Continuously monitor endpoint telemetry for indicators of compromise (IOCs), anomalous behavior, and policy violations.
Threat Hunting: Actively search for hidden threats using behavioral indicators and threat intelligence feeds.
Triage & Response: Rapidly investigate alerts, isolate compromised endpoints, and initiate containment procedures.
Reporting & Recommendations: Provide comprehensive incident reports, including root cause, impact analysis, and mitigation steps.

4. Deliverables to the Client

EDR Deployment Summary: Detailed report on EDR deployment, coverage, and configuration across all endpoints.
Threat Detection Reports: Alerts, event logs, and triage outcomes from monitored endpoints.
Incident Response Reports: Documentation of any incidents, including forensic data, containment actions, and recovery steps.
IOC Feed Integration: Custom IOC feeds correlated with endpoint activity for proactive threat detection.
Continuous Improvement Reports: Periodic reports with detection efficacy, false positive tuning, and recommendations.

5. Client Requirements

Endpoint Inventory: Comprehensive list of all endpoint devices (workstations, servers, laptops, etc.) for agent deployment.
Access to Admin Credentials: Necessary permissions to deploy EDR agents and configure system settings.
SIEM Integration Details: If applicable, information on existing SIEM platforms for EDR log forwarding.
Network Access & Policies: Visibility into firewall rules, endpoint connectivity, and data flow for configuration.
User & Role Information: List of users, roles, and privileges to detect abnormal behavior effectively.

9. Case Study

Insider Threat Detection with EDR

Client: A healthcare organization experiencing unusual data access patterns.
Findings: EDR logs revealed repeated file access from an endpoint outside working hours, leading to the discovery of insider data theft.
Outcome: Endpoint was isolated, employee access was revoked, and the organization implemented stricter access controls and behavioral analytics.
