On April 16, 2021 the National Security Intelligence Review Agency (NSIRA) published a statement on their website that declared they had experienced a ‘cyber incident’ that involved an unauthorized party accessing the Agency’s external network. This network was not used for Secret or Top Secret information. 

NSIRA is responsible for conducting national security reviews of Canadian federal agencies, inclusive of “the Canadian Security Intelligence Service (CSIS) and the Communications Security Establishment (CSE), as well as the national security and intelligence activities of all other federal departments and agencies.” The expanded list of departments and agencies includes the Royal Canadian Mounted Police (RCMP), the Canada Border Services Agency (CBSA), the Department of National Defence (DND), Global Affairs Canada (GAC), and the Department of Justice (DoJ). As a result of their expansive mandate, the Agency has access to broad swathes of information about the activities which are undertaken by Canada’s national security and intelligence community. 

Despite the potential significance of this breach, little has been publicly written about the possible implications of the unauthorized access. This post acts as an early round of analysis of the potential significance of the access by, first, outlining the kinds of information which may have been accessed by the unauthorized party and, then, raising a series of questions that remain unanswered in NSIRA’s statement. The answers to these questions may dictate the actual seriousness and severity of the cyber-incident.

What is Protected Information?

NSIRA’s unclassified information includes Protected information. Information is classified as Protected when, if compromised, it “could reasonably be expected to cause injury to a non-national interest—that is, an individual interest such as a person or an organization.” There are three classes of protected information that are applied based on the sensitivity of the information. Protected A could, if compromised, “cause injury to an individual, organization or government,” whereas compromising Protect B information could “cause serious injury.” Compromising Protected C information could “cause extremely grave injury”. Protected C information is safeguarded in the same manner as Confidential or Secret material which, respectively, could cause injury or could cause serious injury to “the national interest, defence and maintenance of the social, political, and economic wellbeing of Canada” in the case of either being compromised.

Intrusion into protected networks brings with it potentially significant concerns based on the information which may be obtained. Per Veterans Affairs, employee information associated with Protected A information could include ‘tombstone’ information such as name, home address, telephone numbers or date of birth, personal record identifiers, language test results, or views which if made public would cause embarrassment to the individual or organization. Protected B could include medical records (e.g., physical, psychiatric, or psychological descriptions), performance reviews, tax returns, an individual’s financial information, character assessments, or other files or information that are composed of a significant amount of personal information. 

More broadly, Protected A information can include third-party business information that has been provided in confidence, contracts, or tenders. Protected B information in excess of staff information might include that which, if disclosed, could cause a loss of competitive advantage to a Canadian company or could impede the development of government policies such as by revealing Treasury Board submissions. 

In short, information classified as Protected could be manipulated for a number of ends depending on the specifics of what information is in a computer network. Theoretically, and assuming that an expansive amount of protected information were present, the information might be used by third-parties to attempt to recruit or target government staff or could give insights into activities that NSIRA was interested in reviewing, or is actively reviewing. Further, were NSIRA either reviewing non-classified government policies or preparing such policies for the Treasury Board, the revelation of such information might advantage unauthorized parties by enabling them to predict or respond to those policies in advance of their being put in place.
