IIA Three Lines Model (2020) for Government

How does IIA Three Lines Model (2020) apply to government?

Government agencies, defence contractors, and public sector organisations handle sensitive citizen data and critical national infrastructure. IIA Three Lines Model (2020) provides 12 controls across 2 domains that government organisations map onto their sector obligations, so one control satisfies several requirements instead of being evidenced separately for each.

Why government regulators care about IIA Three Lines Model (2020)

Government agencies, defence contractors, and public sector organisations handle sensitive citizen data and critical national infrastructure. Compliance requirements are often mandated by law and subject to oversight by national audit offices.

Government compliance is typically mandatory rather than voluntary. Frameworks like NIST 800-53, Essential Eight, and Cyber Essentials are prescribed by policy. Contractors must meet these standards to win and retain government contracts.

IIA Three Lines Model (2020) provides 12 controls organised across 2 domains that can be mapped to government-specific regulatory requirements. This structured approach helps organisations avoid compliance gaps while reducing the overhead of managing multiple overlapping obligations.

Where government implementations of IIA Three Lines Model (2020) get stuck

Government organisations implementing IIA Three Lines Model (2020) commonly face these challenges:

1

Protecting classified and sensitive citizen data across legacy and modern systems

2

Meeting mandatory government security standards (FedRAMP, IRAP, Essential Eight)

3

Securing critical national infrastructure against state-sponsored threats

4

Managing compliance across large, distributed organisations with limited budgets

5

Achieving interoperability between agency systems while maintaining security boundaries

A working order for government implementations

1. Assess Current State

Conduct a readiness assessment against IIA Three Lines Model (2020) to identify gaps specific to your government environment. Our AI-powered assessment takes 5 minutes and produces a prioritised action plan.

2. Map Regulatory Overlap

Use cross-framework mapping to identify where IIA Three Lines Model (2020) controls satisfy other government regulations. This reduces duplicate effort and accelerates compliance.

3. Implement Priority Controls

Focus on high-risk gaps first, using government-specific threat intelligence to prioritise controls that address your most material risks.

4. Monitor & Improve
