Cybersecurity & Compliance Administrator

Responsibilities

Microsoft Purview Administration (Compliance & Data Governance)

Configure and manage Purview capabilities to support compliance objectives, including data classification and labeling, data loss prevention (DLP), retention and deletion policies, eDiscovery workflows, and compliance reporting.

Develop and maintain Purview‑derived compliance artifacts and evidence outputs to support assessments, audits, due diligence, and continuous monitoring aligned to CMMC 2.0 Level 2 and NIST SP 800‑171.

Define and operate data retention and deletion procedures, integrating with Purview retention controls where appropriate

Microsoft Defender Administration (Threat Protection & Security Operations)

Configure, tune, and operate Microsoft Defender security controls across identity, endpoints, email/collaboration, and cloud applications, consistent with licensing and compliance scope.

Monitor alerts, investigate suspicious activity, and drive remediation actions; reducing noise through continuous tuning and improvements.

Establish and maintain detection and response playbooks, including alert triage, escalation paths, documentation requirements, and post-incident follow-up.

Incident Response & Threat Prevention

Own and maintain the Security Incident Response Plan, including severity definitions, roles and responsibilities, evidence handling, escalation paths, and internal/external communication procedures.

Lead security incident response from identification through containment, eradication, recovery, and lessons learned.

Perform root-cause analysis and coordinate corrective actions with IT administrative staff and relevant stakeholders.

Proactively implement threat prevention measures: hardening, secure configuration baselines, conditional access/MFA enforcement support, and policy-driven risk reduction.

Maintain an incident register covering actual, attempted, and suspected security incidents (including phishing attempts), investigations performed, and outcomes.

Compliance Enablement (CMMC L2 / NIST Controls)

Maintain the System Security Plan (SSP) and Plan of Actions & Milestones (POA&M) for in‑scope systems, ensuring clear implementation statements, ownership, and evidence references.

Support definition and maintenance of the CUI boundary, including systems, users, endpoints, networks, and data flows.

Translate CMMC and NIST control requirements into concrete configurations, procedures, and ongoing monitoring activities across Microsoft 365, on‑prem infrastructure, and restricted or air‑gapped environments.

Collect, organize, and maintain audit‑ready evidence to support internal assessments, customer diligence, and third‑party assessments.

Define and maintain a centralized logging strategy (SIEM) spanning cloud and on‑prem environments, including ingestion of logs from identity systems, endpoints, email, servers, firewalls, VPNs, and IDS/IPS platforms.

On‑Prem & Air‑Gapped Security

Establish and operate secure data transfer procedures for air‑gapped and restricted environments, including removable media governance, integrity validation, malware scanning, and chain‑of‑custody documentation.

Partner with Network Architecture to design and maintain secure monitoring architectures for restricted and air‑gapped environments, including TAP/SPAN placement, IDS deployment, and segmentation alignment with OT/ICS security best practices

Security Engineering & Integrations

Support integrations between cloud-based services and the Microsoft security/compliance ecosystem (e.g., log sources, alerting, ticketing workflows, SSO/identity integrations).

Contribute to automation where appropriate (e.g., scheduled scripts, workflows, or playbook-style response actions).

Cross-Functional Collaboration & Communication

Work closely with IT and engineering teams to ensure smooth operations and secure-by-default practices.

Document, categorize, and prioritize security issues to ensure efficient escalation and resolution.

Enforce approved security, compliance, and privacy policies and contribute to ongoing policy development and improvement.

Collaborate with Network Architecture on secure network design, segmentation strategy, and enforcement controls including firewall policy, IDS/IPS, and Zero Trust network principles.
