The Weak Link in Canada’s Cyber Armor: Auditor General of Canada Warning on PKI and Cryptographic Governance

A new report from Canada’s Auditor General has issued a stark warning that goes far beyond typical cybersecurity shortcomings. It reveals critical failures in the very foundations that underpin trust and security in government digital services: Public Key Infrastructure (PKI) and cryptography.

While the audit doesn’t mention PKI by name, its findings paint a dire picture of the ecosystem in which digital certificates, encryption keys, and cryptographic protocols must operate. The report identifies that the federal government lacks a complete inventory of its IT assets, has stalled a central monitoring project, and suffers from poor coordination during incidents. For any security professional, this translates to a single, alarming reality: You cannot manage what you cannot see, and you cannot protect what you cannot coordinate.

Without a comprehensive asset inventory, how can the government ensure every server and laptop has a valid digital certificate? How can it rapidly patch a critical cryptographic vulnerability like Log4Shell if it doesn’t know all the affected systems? The delayed response to a major 2024 attack, cited in the report, shows precisely what happens when the processes for sharing critical information—like a compromised certificate authority or a widespread encryption flaw—break down.

This audit is a clarion call for reinforcing the pillars that support PKI. It validates that the greatest cryptographic strength is irrelevant if the underlying governance—visibility, automation, and collaboration—is weak. In the following analysis, we dissect the Auditor General’s findings through a cryptographic lens and outline the essential steps to build a resilient, trustworthy digital government.

In the following analysis, we break down the key findings of the Auditor General’s report and translate them into actionable insights, demonstrating how addressing these very gaps is the key to building a resilient, world-class security framework.

1. Directly Relevant: Incomplete IT Asset Inventory (A Critical Prerequisite for PKI)

This finding is perhaps the most directly relevant, as you cannot properly manage cryptographic keys and certificates if you don’t know what devices and systems you have.

• Section: “Central inventories of the government’s IT assets were incomplete, increasing risk to cyber attacks” (Pages 11-12, Paras 26-28)

• Relevance to PKI/Cryptography: A complete and accurate asset inventory is a fundamental prerequisite for any effective PKI. Without knowing all servers, laptops, and network devices, it is impossible to ensure that:

  • All systems have the necessary cryptographic libraries and are configured correctly.

  • Digital certificates are deployed to all required endpoints.

  • Expired or compromised certificates can be identified and revoked in a timely manner.

  • Systems relying on encryption (e.g., for data-at-rest or data-in-transit) are properly accounted for and managed.

2. Highly Relevant: Gaps in Monitoring and Response (Impacting Cryptographic Incident Management)

The inability to monitor and respond effectively would severely hamper the response to incidents involving compromised cryptography, such as a stolen private key.

• Section: “There was a gap in monitoring suspicious cyber security events…” (Pages 10-11, Paras 22-25)

• Relevance to PKI/Cryptography: A Security Information and Event Management (SIEM) system, which was delayed, is crucial for detecting anomalies that might indicate cryptographic failures or attacks. For example, it could alert on:

  • Systems failing to establish TLS connections (suggesting certificate issues).

  • Unusual authentication attempts that bypass cryptographic controls.

  • Patterns consistent with cryptographic downgrade attacks.
    The lack of this tool means such signals might be missed.

3. Highly Relevant: Poor Coordination and Information Sharing (Affecting PKI Governance)

The governance and response framework for cyber incidents is weak, which would directly impact the management of a severe PKI-related incident.

• Section: “Coordination and information sharing procedures and protocols for cyber attacks were incomplete…” (Pages 13-14, Paras 32-34)

• Relevance to PKI/Cryptography: A serious cryptographic incident, such as the compromise of a root Certificate Authority (CA) or a widespread vulnerability in an encryption standard, would require swift and coordinated action across the government. The documented 7-day delay in sharing critical information during an attack (Exhibit 5) shows that the processes for responding to a crisis that could invalidate trust across government systems (the very purpose of PKI) are inadequate.

4. Implicitly Relevant: The New Cyber Security Strategy (The Strategic Umbrella)

The strategy outlines goals that inherently depend on strong cryptography.

• Section: “A new strategy guided the government’s cyber security activities” (Pages 4-5, Paras 10-11, and Exhibit 2)

• Relevance to PKI/Cryptography: The strategy’s objectives, such as “Prevent and resist cyber attacks more effectively” and “Establish a framework to improve the ability to detect and prevent fraudulent activity,” are heavily reliant on cryptographic techniques like digital signatures, encryption, and certificate-based authentication. The strategy’s success is contingent upon a robust underlying PKI.
