System Administrator

Description

• Implement and enforce app consent and app registration governance in Entra ID.
• Deploy and operate Microsoft Defender for Endpoint and Defender for Office 365 with advanced telemetry, custom detection rules, automated containment playbooks, and integration into the tenant's continuous monitoring and incident response processes.
• Ensure Defender signals feed into a centralized SIEM or Microsoft Sentinel for correlation, retention, and evidence for assessments.
• Configure unified logging, retention, and automated evidence collection for controls mapped to NIST SP 800-171; ensure logs meet retention and integrity requirements for assessments.
• Implement strict guest access and external sharing controls for Teams, SharePoint, and OneDrive with exception workflows and approvals.
• Maintain identity logs and evidence retention to support audits and assessments against NIST SP 800-171 controls.
• Maintain a formal tenant baseline configuration document, change control process, and Infrastructure-as-Code or scripted templates to reproduce hardened settings.
• Address escalation requests from Helpdesk Analyst and MSSP as needed
• Configure Microsoft Purview for DLP, sensitivity labeling, encryption, retention, and eDiscovery tailored to CUI handling requirements.
• Manage Autopilot profiles and lifecycle to ensure new company devices meet CUI security baselines before granting access
• Produce and maintain artifacts required for audits: control evidence, configuration snapshots, access review records, and incident logs.
• Own periodic configuration drift checks, secure tenant setting reviews, and documented remediation actions for audit trails
• Build PowerShell/Graph automation to produce recurring compliance reports, control evidence packages, license and entitlement reports, and remediation tickets for noncompliant items.

• Vet and configure SSO and data flows for third-party SaaS (e.g. Adobe, Bluebeam, backups) to ensure minimal exposure of CUI and appropriate contractual, technical, and monitoring controls.
• Enforce device posture for CUI access with Intune: strict enrollment gates, baseline configuration profiles, compliance policy strictness, controlled device enrollment (company-owned only where required), and device encryption enforcement.
