SOC Analyst - Sentinel Expert

Description

• Leverage Built-in Templates: Utilize and customize built-in analytics rule templates from Microsoft and the community to accelerate detection coverage.
• Research & Development: Stay current with the latest adversary TTPs (Tactics, Techniques, and Procedures) and develop new hunting hypotheses.
• Stakeholder Reporting: Develop and maintain dashboards and workbooks to provide visibility into the security posture, key metrics (KPIs), and threat landscape for management and other stakeholders.
• Playbook Development: Design, build, and maintain Azure Logic Apps playbooks to automate incident response and orchestrate security workflows (e.g., auto-quarantine emails, disable user accounts, trigger investigations).
• Proactive Hunting: Conduct proactive threat hunting campaigns using advanced KQL queries to uncover hidden threats that may evade traditional detection methods.
• Cross-Functional Collaboration: Work closely with the IT infrastructure, cloud, and application development teams to ensure proper logging and security best practices are followed.
• Automation Rule Management: Create and manage Automation Rules to standardize incident triage, assignment, and lifecycle (e.g., auto-close false positives, set severity levels).
• Lifecycle Management: Manage the lifecycle of analytics rules, watchlists, hunting queries, and workbooks.
• Health Monitoring: Proactively monitor the health, performance, and cost of the Sentinel environment. Troubleshoot and resolve issues related to data ingestion, agent health, and analytics rule execution.
• Data Onboarding: Manage the ingestion of log data from various sources (e.g., Microsoft 365 Defender, Azure AD, Azure Activity Logs, on-premises servers, firewalls, endpoints via Azure Arc and AMA).
• Forensic Data Enrichment: Use Sentinel's investigation graph and entity pages to enrich incident data and understand the full scope of an attack.
• Analytics Rule Creation: Design, develop, test, and tune custom analytics rules using Kusto Query Language (KQL) to detect malicious activity, threats, and anomalies.
• Incident Analysis: Serve as an escalation point for Tier 2/3 SOC analysts, providing expertise during complex incident investigations.
• Documentation: Create and maintain detailed documentation for runbooks, playbooks, hunting guides, and standard operating procedures (SOPs).
• Hunting Notebooks: Develop and utilize Jupyter notebooks within Sentinel for deep-dive, interactive investigations.
• Provide a "second opinion" on the scope and impact of a potential security incident.
• Threat Intelligence Integration: Integrate threat intelligence platforms (TIP) and indicators of compromise (IOCs) into Sentinel to enhance detection capabilities.
• Deployment & Configuration: Architect, deploy, and configure Microsoft Sentinel workspaces, including data connector setup, log ingestion, and workspace optimization.
• SOC Use Case Implementation: Translate business requirements and threat intelligence into effective, actionable detection logic within Sentinel.
• Mentor junior engineers and analysts on KQL, Azure, and security concepts.
• Act as an escalation point for Tier 2/3 SOC analysts struggling with a complex investigation.
• Mentorship: Mentor and provide technical guidance to junior SOC analysts and engineers.
