OTTAWA—Canada’s electronic spy agency is worried about a Canadian Edward Snowden.

The Communications Security Establishment began educating new employees and existing staff about “insider threats” in 2013, according to documents obtained by the Star.

The crackdown on “unauthorized disclosures” was tied directly to the whistleblower Snowden, who pulled back the curtain on a pervasive electronic spying apparatus in the United States and its Five Eyes partners, including CSE in Canada.

“Following the unauthorized disclosures of Canadian Navy Sub-Lieutenant Jeffrey Delisle (2012) and NSA contractor Edward Snowden (2013), CSE has intensified its efforts to tighten already stringent security,” the documents, obtained under access to information law, state.

“CSE’s security responses to the unauthorized disclosures comprise both new and existing measures as part of ongoing efforts to better safeguard intelligence.”

Most of those “new and existing measures” have been censored from the heavily redacted document, a 2013-14 annual report to the minister of national defence.

Almost everything Canadians know about CSE’s modern operations comes from Snowden, who fled the United States with a vast amount of information on the U.S. National Security Agency and its counterparts in Canada, the United Kingdom, Australia and New Zealand.

Snowden gave that information to journalist Glenn Greenwald, who has been writing about the NSA’s operations since. In Canada, Greenwald partnered with the CBC to release select documents on CSE’s operations, including:

Tracking free wifi traffic in a Canadian airport, thought to be Pearson International in Toronto.

A program called EONBLUE, which collects vast amounts of Internet data at 200 “backbone” sites.

A project called Levitation that reportedly allows the agency to monitor the traffic of millions of users on a popular file-sharing site.

A number of discrete instances of spying or assisting the United States’ spying, including at the G20 summit in Toronto and snooping around in the Brazilian ministry of mining and energy.

In the report, former CSE chief John Forster said those disclosures have made the agency’s job more challenging.

“We continue to see significant challenges as a result of these disclosures, including the changes in target behaviors,” Forster said.

If CSE provided any concrete examples of how target behaviours have changed, it’s either not included or censored from the documents obtained by the Star.

The agency seemed concerned with their new public profile — CSE has existed since the Second World War, but has rarely seen a flurry of public attention like 2013. The report noted that the increase in public awareness lead to several “civic protest activities” on its properties.

These protests were seen as a threat to the agency.

“Having identified an increase in threats to CSE employees and assets, a thorough review of security measures was conducted to identify areas where greater risk controls may be warranted,” the report reads.

In addition to educating employees about inside jobs, CSE has committed $45 million over five years to upgrade and enhance the federal government’s Top Secret network.

The Star requested an interview with both CSE and Julian Fantino, the junior minister of defence who handles media requests on CSE, including sending specific questions. Fantino did not respond to the Star’s request.

In a written statement, CSE declined to discuss specifics about their education efforts.

“While we can’t discuss specific advice to staff on insider threats, CSE provides continuous security education and training to staff, which includes increasing staff awareness of insider threat issues,” the agency wrote.
