A Closer Look at the CRA's Cybersecurity Audit

In the rapidly advancing digital landscape, government agencies play a crucial role in ensuring the security and integrity of sensitive information. The Canada Revenue Agency (CRA), responsible for managing over $586.3 billion in revenues and pension contributions, has been a pioneer in adopting digital services. With 91% of individual and 94% of corporate income tax returns filed digitally, the CRA has successfully adapted to the evolving needs of Canadians.

However, no system is immune to potential threats, and the CRA recently underwent a cybersecurity audit covering a subset of key controls deemed higher risk. The objective was clear: to provide assurance that the controls in place are effectively safeguarding the CRA's IT systems from potential digital attacks.

The audit, conducted from April 1, 2021, to March 31, 2022, highlighted areas requiring improvement to further fortify the CRA's cybersecurity posture. While the audit did not scrutinize all controls within the cybersecurity program, its findings underscored the importance of continual vigilance in the digital age.

One significant recommendation arising from the audit is the establishment of a second line of defense for cybersecurity. This entails evaluating and monitoring internal controls related to cybersecurity, aligning corporate policy instruments with the Treasury Board Policy on Service and Digital.

The Security Branch acknowledges the findings, emphasizing that the audit did not expose immediate vulnerabilities but rather revealed symptoms of a broader cyber governance gap within the CRA. Their action plan aims to address both the individual findings and the overarching governance issues.

The audit identified six specific controls for improvement, a small fraction of the Government of Canada's comprehensive cybersecurity risk management model. This model aligns with the National Institute of Standards and Technology (NIST) Cyber Security Framework, emphasizing the need to identify, protect, detect, respond, and recover from potential threats. The paradigm of "defense in depth" employs various risk controls to create a layered defense strategy.

In response to the audit, the CRA is committed to closing the identified governance gap and ensuring the effectiveness of its cybersecurity measures. The agency recognizes the value of the audit in enhancing its cyber governance framework and is poised to implement action plans that align with industry best practices.

As we reflect on the findings of the CRA's cybersecurity audit, it underscores the importance of constant improvement and adaptation in the face of evolving cyber threats. Organizations must embrace a multi-layered defense strategy, as recommended by leading authorities like the Institute of Internal Auditors and the Information Systems Audit and Control Association.
