Information System Security Manager (ISSM) - Cloud Security Architect

Mission & Impact

AETC recruits, trains, and educates Airmen to deliver 21st‑century airpower. AWAKEN is AETC's enterprise‑managed, accredited wireless/network service spanning flight lines, classrooms, dorms, and administrative facilities across the U.S. As ISSM - Senior Cloud Security Architect, you will lead cybersecurity for AWAKEN's cloud‑native, software‑defined, Zero‑Trust transformation, ensuring secure, reliable connectivity that advances the training mission at scale.

Position Summary

This role is ideal for a hands‑on cloud security engineer first, policy‑aware second. You will actively engineer and enforce security controls across cloud and hybrid environments while maintaining RMF/ATO governance, continuous monitoring, and compliance. Expect roughly 66% platform engineering (secure design/implementation, automation, remediation) and 33% governance/policy enforcement (RMF artifacts, POA&Ms, attestations, board cadence).

Core Responsibilities

Governance, RMF & Compliance

• Lead RMF/ATO/ATC activities: develop and maintain SSP, control implementations, evidence, POA&Ms, and continuous monitoring strategy; coordinate with Government ISSO, SCV, AO; sustain ATO per USAF guidance.
• Enforce DISA STIG/SRG configurations across enterprise hardware/software; ensure timely patching/bug‑fix deployment and flaw remediation with documented procedures.
• Enable and manage ACAS/Nessus vulnerability scanning (external and internal), deliver bi‑weekly/30‑day reports, and drive remediation to closure.
• Support incident response: immediate notification (phone/email) within six hours of discovery; 30‑day follow‑up reporting; maintain secure audit logs and event evidence.
• Participate in PMRs and CCBs; maintain enterprise baseline and CM Plan; provide artifacts (topologies, inventories, rack elevations, ports/protocols) and read‑only visibility to Government tools/portals.

Cloud Security Architecture

• Implement secure configurations in AWS, Azure, GCP (or comparable platforms).
• Engineer IAM: RBAC, least‑privilege, multi‑account strategy, federation (IdP integration).
• Configure cloud‑native logging/monitoring/alerting for security visibility (e.g., provider equivalents to CloudWatch).
• Apply Zero‑Trust principles across cloud networking and service‑to‑service comms (authN/authZ, encryption, segmentation).
• Develop IaC security baselines; codify guardrails/policies; enforce drift detection.

Vulnerability Management & Compliance

• Operate ACAS and vulnerability scanners; analyze findings; prioritize remediation; validate fixes; sustain POA&Ms and compliance dashboards (NIST SP 800‑53, DISA STIGs, CMMC as applicable).
• Produce traceability mapping of technical controls to required frameworks; prepare audit evidence and assessor packages.

Platform Security (Linux, Windows, Virtualization)

• Linux (≈70%): hardening, auditing, patching, secure configuration, STIG application/validation.
• Windows (≈30%): server security configuration, patch management, policy baselines.
• Virtualization: secure VMs and management planes (e.g., VMware), including isolation, logging, and role segmentation.

Kubernetes & Container Security

• Secure clusters: RBAC, network policies, secrets management, pod security standards; image signing and vulnerability scanning; protect service meshes and encrypted service communication.

Networking & Zero Trust

• Apply TCP/IP, firewalls, VLANs, VPNs, routing, micro‑segmentation to enforce least‑privilege access across hybrid environments; integrate CoS/QoS and performance KPIs where applicable.

Automation & DevSecOps

• Bash/Python automation for remediation and control validation.
• Terraform/Ansible (or equivalent) for enforcing baselines, policy‑as‑code, and repeatable secure deployments.
• CI/CD security integration, pre‑deployment testing, and lab validation prior to production changes.

Collaboration & Leadership

• Serve as trusted advisor to COR and Government Technical Leads; brief diverse stakeholders in clear, mission‑focused terms.
• Coordinate with PM, architects, network engineers, helpdesk/T3, and cybersecurity analysts; maintain cadence with PMRs and escalation SOPs.
