The Challenge

A federal science agency needed to strengthen cybersecurity governance across a large AWS environment supporting scientific research, mission systems, and public-facing services. With hundreds of AWS accounts and a growing portfolio of cloud services, the program needed consistent security oversight without slowing cloud adoption.

The challenge extended beyond maintaining compliance. The agency needed ongoing leadership across cloud governance, system authorization, risk management, continuous monitoring, security assessments, and longer-term security planning.

KITC's Role

KITC has served as a key cybersecurity leader for the program for several years, with responsibility spanning day-to-day security operations, federal compliance, enterprise cloud governance, and strategic security initiatives.

KITC leads Risk Management Framework (RMF) activities throughout the authorization lifecycle, including security assessments, risk analysis, security documentation, vulnerability validation, remediation tracking, continuous monitoring, and Authority to Operate (ATO) activities.

At the cloud governance level, KITC helped establish a consistent security model across hundreds of AWS accounts. The team implemented automated policy enforcement and security controls, centralized security monitoring and logging, and compliance oversight to give the program greater visibility and consistency across its AWS environment.

KITC also evaluates new cloud services and technologies before adoption, providing security recommendations and helping technical teams address potential risks. This gives the agency a practical way to introduce new capabilities while maintaining its federal security requirements.

Expanding the Program's Security Strategy

As the engagement grew, the agency turned to KITC for broader cybersecurity planning.

KITC developed a comprehensive Security Operations Center (SOC) Design Document assessing the program's existing security capabilities and defining recommendations for its future security operations.

The team also developed a virtual Security Operations Center (vSOC) strategy and whitepaper to help the agency evaluate a future-state approach to centralized security operations. The work examined the program's current capabilities and developed recommendations spanning security operations, incident response, security technologies, threat intelligence, staffing considerations, and future-state planning.

These efforts moved KITC's role beyond compliance execution. The team was helping the program determine how its broader cybersecurity operations should mature as the cloud environment and threat landscape changed.

The Results

KITC's work has produced measurable results across security, compliance, governance, and program operations.

Multiple successful ATOs with zero audit findings. KITC's leadership across RMF, security assessment, documentation, continuous monitoring, and authorization activities has helped the program successfully obtain and maintain multiple Authorities to Operate, while achieving zero findings during external audits.
25% reduction in compliance reporting cycles. KITC automated and centralized portions of compliance monitoring and reporting, reducing reporting cycles by 25% and decreasing the administrative effort required to maintain oversight across the environment.
Governance across hundreds of AWS accounts. KITC helped establish a scalable governance structure for a large AWS environment, applying consistent security requirements and monitoring across hundreds of accounts.
A defined path for future security operations. Through the SOC Design Document and vSOC strategy, KITC provided the agency with concrete recommendations for strengthening and maturing its security operations rather than focusing solely on current compliance requirements.
Ongoing security leadership. KITC continues to work across security, cloud, engineering, and program teams to manage cybersecurity risk, evaluate new technologies, maintain authorization requirements, and guide security decisions as the environment changes.

A Long-Term Cybersecurity Partnership

Over the course of this multi-year engagement, KITC's role has expanded from cybersecurity and compliance support to broader leadership across cloud security, risk management, governance, and strategic security planning.

Today, KITC continues to help the agency maintain its security and compliance requirements, manage risk across hundreds of AWS accounts, and make informed security decisions as its cloud environment grows and changes.
