Summary: Enhancing Canada’s Critical Infrastructure Resilience to Insider Risk

Enhancing Canada’s Critical Infrastructure Resilience to Insider RiskEarlier this year, the Canadian Government released a document to provide Canadian critical infrastructure organizations information on how to mitigate insider risk. It defines insider risk as “anyone with knowledge or access to an organization’s infrastructure (both physical and computer networks) who maliciously, or by chance, misuses their trusted access to harm the organization’s employees, customers, assets, reputation or interests. As defined by Carnegie Mellon’s CERT Insider Threat Centre (CERT Inside Threat Center, 2016), an insider risk is a person that works from within an organization to subvert the confidentiality, integrity, and availability of the information contained within the walls of that entity.”

Given security risks are relevant for all technology professionals in all industries, it is a good document to read through and understand. If you can’t look at it immediately, here is a summary of the eight recommended security actions, divided into three themes:
