Azure Cloud Security and Compliance for AC Transit — California County Transit Authority
AC Transit needed to secure their Azure cloud environment and achieve HITRUST and PCI DSS compliance…
A public research university with 44,000 students needed to secure their AWS cloud environment — protecting student data, research data, and institutional systems across a large, complex, and highly distributed academic environment with unique compliance obligations spanning HIPAA, PCI DSS, FERPA, and state privacy laws.
Propelex delivered comprehensive AWS cloud security for the university — hardening the cloud environment, implementing continuous monitoring and threat detection, and aligning the infrastructure to the overlapping compliance frameworks that govern a public research institution handling student, health, and payment card data simultaneously.
Public research universities present one of the most complex compliance environments in any sector. A single institution simultaneously handles student education records governed by FERPA, health data for campus medical services subject to HIPAA, payment card information for tuition and campus commerce covered by PCI DSS, research data with federal grant obligations, and personal information subject to evolving state privacy laws — all within a single AWS cloud environment serving over 44,000 students, thousands of faculty and staff, and a large research community.
Propelex delivered comprehensive AWS cloud security for this public research university — hardening the environment, implementing continuous monitoring, and formally aligning the cloud infrastructure to the overlapping compliance frameworks that govern every dimension of university operations.
The client is a public research university with a student population of over 44,000 — a large institution with significant research programs, a full campus health services operation, multiple colleges and departments each with their own technology needs, and an administrative infrastructure that spans HR, finance, student services, and facilities management.
Their AWS environment had grown organically as departments adopted cloud services at their own pace and for their own needs — a pattern common in higher education that produces a cloud footprint that is broad, diverse, and difficult to govern consistently from a security and compliance perspective. The client name is kept confidential under NDA.
Higher education cloud security is genuinely harder than most enterprise cloud security — not because the technologies are more complex but because the organizational and compliance context is more demanding:
The core challenge of university cloud security is making a single AWS environment simultaneously satisfy multiple compliance frameworks with different requirements — without creating a compliance patchwork that is impossible to maintain:
Propelex implemented a comprehensive AWS security hardening program addressing the specific challenges of a large, decentralized university cloud environment:
A university AWS environment changes constantly — departments provision new resources, students and faculty accounts are created and deactivated on academic calendars, and research projects spin up and down on grant timelines. Static security controls applied once are insufficient:
AWS Config rules and Security Hub findings were configured to provide continuous, automated compliance monitoring — detecting new resources that fall outside compliance baselines, identifying configuration drift as the environment changes, and generating findings that direct the security team’s attention to the most significant issues rather than requiring manual review of a large and constantly changing environment.
Amazon GuardDuty was enabled and configured across all accounts to provide ML-based threat detection — identifying unusual API activity, compromised credentials, and network-level threats across the university’s entire AWS footprint. For a 44,000-student institution, the volume of legitimate activity makes manual threat hunting impossible — automated detection is the only operationally viable approach.
The university’s AWS environment was hardened systematically across all accounts — addressing the configuration inconsistencies that had accumulated as departments adopted cloud services independently, and establishing security baselines that apply uniformly regardless of which department or program owns the resources.
FERPA, HIPAA, and PCI DSS compliance requirements were simultaneously addressed within the single AWS environment — through a combination of account structure, network segmentation, access controls, and audit logging that satisfies each framework’s requirements without requiring separate infrastructure for each compliance domain.
Automated compliance monitoring and threat detection replaced manual review processes — providing the security team with continuous visibility into a large, distributed, and constantly changing AWS environment that no manual process could keep pace with at 44,000-student scale.
The 44,000 students, faculty, staff, and research community members whose data the university manages are now served by a cloud security posture that is formally aligned to the compliance frameworks governing their information — providing the documented protection that accreditation requirements, regulatory examinations, and institutional accountability demand.
University cloud security requires a different approach than enterprise cloud security — not because the technical controls are fundamentally different but because the organizational context, the compliance framework stack, and the user population all create challenges that enterprise-focused security programs are not designed to address. Academic culture, decentralized governance, and the simultaneous application of FERPA, HIPAA, and PCI DSS within a single environment require security expertise that combines technical depth with a genuine understanding of how research universities operate.
Propelex brought that combination to this engagement — delivering AWS security hardening and compliance alignment that respected the university’s operational context while establishing the formal controls needed to satisfy regulatory requirements and protect the students and researchers the institution serves.
The university established a hardened, continuously monitored AWS environment with formal compliance alignment across HIPAA, PCI DSS, and FERPA — protecting the data of 44,000 students and a large research community while giving the institution the documented security posture needed for regulatory examination and accreditation requirements.
