Deployment Responsibilities

Elastic Security & SIEM Implementation:

• Design, architect, and deploy Elastic Security environments (Elastic Cloud or self-managed) tailored to customer requirements
• Configure data ingestion pipelines using Elastic Agent, Beats (Filebeat, Metricbeat, Auditbeat, Winlogbeat), and Logstash for logs, endpoints, cloud platforms, and network sources
• Build and optimize detection rules, dashboards, visualizations, and analytics in Kibana for actionable threat intelligence
• Implement prebuilt and custom detection rules aligned with the MITRE ATT&CK framework
• Configure machine learning anomaly detection jobs and UEBA packages for behavioral analytics
• Conduct performance tuning, capacity planning, and searchable snapshot configuration for cost-effective data retention

Elastic Defend (EDR/XDR) Deployment:

• Deploy, configure, and tune Elastic Defend integration across customer endpoints (Windows, macOS, Linux) and cloud workloads
• Configure endpoint protection policies including malware prevention, ransomware protection, memory threat detection, and malicious behavior prevention
• Establish credential hardening and Device Control policies to prevent data loss and unauthorized access
• Configure response actions, trusted applications, event filters, and exception lists to minimize false positives
• Integrate endpoint telemetry with SIEM using Elastic Common Schema (ECS) for comprehensive correlation
• Manage agent deployment at scale using Fleet for centralized configuration and policy management

Cloud Security Deployment

• Deploy Cloud Security Posture Management (CSPM) to evaluate AWS, Azure, and Google Cloud Platform configurations against CIS benchmarks
• Configure Kubernetes Security Posture Management (KSPM) for EKS and self-managed Kubernetes clusters
• Implement Cloud Native Vulnerability Management (CNVM) to discover and scan cloud workload vulnerabilities
• Set up Cloud Workload Protection for runtime protection of cloud environments
• Configure agentless ingestion and cloud asset inventory for comprehensive visibility

Project Delivery

• Lead technical scoping, planning, and execution of deployment projects
• Leverage Automatic Migration capabilities to migrate detection rules from other SIEM platforms

• Leverage host and user risk scores with asset criticality assessments to prioritize investigations
• Investigate emerging threats, vulnerabilities, and adversary TTPs using Elastic Security Labs research
• Identify security gaps and propose enhancements to strengthen customer defenses
• Contribute to detection rule development aligned with MITRE ATT&CK techniques

Incident Response Support:

• Support incident triage, containment, remediation, and recovery using Elastic Security response capabilities
• Execute endpoint response actions including host isolation, process termination, and file retrieval
• Analyze malicious files, processes, persistence mechanisms, and attacker behavior on compromised endpoints
• Utilize osquery integration for additional host context during investigations
• Assist customers during large-scale or targeted breach investigations

Content Development & Automation:

• Develop custom detection rules using KQL and ES|QL query languages
• Configure and tune machine learning anomaly detection jobs for customer-specific use cases
• Build ingest pipeline logic for data normalization and enrichment
• Use scripting (Python, PowerShell) to automate tasks and integrate with third-party SOAR platforms
• Evaluate new Elastic Security features and AI capabilities for customer adoption
• Configure automated response actions triggered by detection rules

Qualifications Required:
