• Governance & Regulatory Assurance: Perform governance, compliance, and assurance activities to ensure the platform aligns with NIST SP 800-53, NIST RMF, and FedRAMP requirements across all environments and instances.
• Security Requirements & Control Design: Define, document, and assess security requirements for implementations; support control selection, tailoring, and technical implementation across instance configurations and workflows.
• Platform Security & Hardening: Build, configure, and enforce instance security controls, including Access Control Lists (ACLs), Role-Based Access Control (RBAC), data encryption (e.g., Column-Level Encryption, encryption in transit), IP address restrictions, and security properties aligned with the Hardening Guide.
• Monitoring & SIEM Integration: Configure and monitor event and security telemetry; maintain integrations with enterprise SIEM platforms for continuous monitoring, alert correlation, and incident detection across platform operations.
• Continuous Monitoring (NIST CA-7): Support continuous monitoring programs for the boundary, including automated evidence gathering, control validation, and recurring assessment activities.
• POA&M Lifecycle Management: Manage the Plan of Action and Milestones (POA&M) lifecycle for the platform: document findings, assign technical owners, track milestones, validate remediation testing, and close security items.
• ATO & Artifact Development: Develop and maintain Authorization to Operate (ATO) packages for the ecosystem, including System Security Plans (SSPs), technical boundary diagrams, control implementation summaries, and supporting evidence artifacts.
• Audit & Assessment Coordination: Support internal and external security assessments; coordinate directly with Security Control Assessors (SCAs), federal auditors, and Third-Party Assessment Organizations (3PAOs) during formal evaluations.
• Cross-Functional Collaboration: Partner with System Owners, ISSOs, platform administrators, developers, and solution architects to implement security controls and remediate audit findings.
• Vulnerability Management: Perform vulnerability management across the platform and integrations: review platform patch levels, evaluate CVEs, prioritize remediation, and track resolution timelines.
• Baseline Compliance & Configuration Management: Validate and enforce secure configuration baselines, utilizing the Instance Security Center (ISC) and applicable security benchmarks (e.g., CIS benchmarks, DISA STIGs).
• Incident Response & SecOps: Assist with security incident response activities impacting the environment, supporting triage, root-cause investigation, containment, and formal reporting.
• Log Review & Audit Compliance: Conduct log analysis, including transaction logs, system logs, and administrative audit trails, to detect anomalous activity and maintain compliance with federal logging mandates (e.g., OMB M-21-31).
• Identity & Access Governance (AC-2): Oversee user access controls, privileged access management, single sign-on (SSO/MFA) configurations, and periodic user access recertifications within the platform.
• Asset & Configuration Inventory: Maintain configuration integrity and asset visibility within the Configuration Management Database (CMDB) in accordance with RMF inventory and categorization standards.
• Security Documentation & SOPs: Develop and maintain technical security architecture documentation, standard operating procedures (SOPs), and operational playbooks for platform security administration.
• Project Delivery & Capability Rollout: Formulate and execute project plans for deploying, upgrading, and maintaining security capabilities, modules, and platform updates.
• Risk Assessments & Change Impact Analysis: Perform risk assessments and security impact evaluations for platform change requests, plugin installations, update sets, custom integrations, and security policy exceptions.
• Secure Platform Development (DevSecOps): Support secure development practices for custom applications and catalog items, conducting security reviews of Script Includes, Business Rules, client scripts, and automated test pipelines.
• Threat Intelligence & Detection: Leverage threat intelligence feeds to refine security workflows, identify emerging platform threats, and enhance incident containment playbooks.
• Metrics & Executive Reporting: Track, aggregate, and report security posture metrics (e.g., instance hardening scores, vulnerability remediation timelines, POA&M aging, and audit compliance rates) using dashboards and reporting tools.
