Understanding ATO: Meaning, Process, and Risks

In the realm of information technology (IT) and cybersecurity, ATO—an acronym for Authorization to Operate—holds significant importance. This complex and crucial process is an integral part of managing and mitigating cyber risks in both governmental and business operations.

What is ATO?

Simply put, ATO, or Authorization to Operate, is a formal approval granted by a designated authority, authorizing the operation of a particular IT system within an organization. This certification signifies that the organization has weighed the benefits of using the system against the potential operational risks it may introduce.

The Importance and Necessity of ATO

Our growing dependency on IT systems and digital platforms has made us more susceptible to cyber risks, account takeover fraud, and even identity theft. This underlines the need for a robust mechanism for managing these risks. ATO serves this purpose by evaluating the security controls of new and existing systems.

The Legal Mandate for ATO

The Federal Information Security Modernization Act mandates federal agencies to have systems in place to assess and monitor security and privacy risks. This is usually achieved through inter-agency bodies like the Federal Risk and Authorization Management Program or individual agencies.

The ATO Application Process

The process of acquiring an ATO accreditation differs based on the type of IT system requesting authorization and the government systems it seeks access to. However, the procedure usually aligns with the NIST Risk Management Framework (RMF) and includes the following steps:

1. Categorization of the system within the organization based on potential adverse impact.
2. Selection of relevant security controls.
3. Implementation of the security controls.
4. Assessment of the effectiveness of the security controls.
5. Authorization of the system.
6. Continuous monitoring of the system.

The Duration and Cost of ATO Accreditation

The ATO process is extensive and sometimes takes several years to complete. The cost of the process is highly variable, often exceeding $1 million. This is due to the extensive documentation and reporting required, which largely remains a manual process.

Interim Authority to Test (IATT)

In some cases, an Interim Authority to Test (IATT) may be issued, which grants temporary authorization to test a system without live data for a defined period under specified conditions or constraints.

Post-Accreditation Monitoring

Once the system is authorized, it's subjected to careful and continuous monitoring to maintain confidence in the system and its controls. This includes incident response and management, as well as change management, all governed by documentation submitted as part of the ATO package.

Software Risk Management in Private Sector

In the private sector, organizations need to assess their suppliers' software assurance practices. There are various sets of standards and certifications that organizations can require their vendors to implement before introducing their software into their networks.

The Bottom Line

For companies with dual-use software products—those with both civilian and military applications—an ATO can be a significant barrier to entry to the government market. However, Fast Track ATOs, which use a streamlined approach to achieve accreditation more quickly, can help mitigate these challenges.

The ATO process, though imperfect, currently provides the most systematic way for the government and private sector to manage risk within their information systems—an essential function in this increasingly complex cyber risk environment.
