Insider threats are the cyber risk that often looks like “normal work”: trusted access, everyday shortcuts, and small decisions that can snowball into real incidents.
This talk will demystify what “insider threat” actually means, distinguishing malicious insiders, well-meaning but risky behaviour (the “oops” factor), and compromised insiders where legitimate accounts are used by attackers. It will explore why insider risk is fundamentally sociotechnical—shaped by incentives, workload, culture, and how access and controls are designed.
The talk will then move from “oops” to “ops” with practical, proportionate mitigations that protect security without eroding trust. It will cover a toolkit of governance and technical measures such as least privilege, separation of duties, strong onboarding/offboarding, purposeful logging and monitoring, and awareness approaches that change behaviour (not just tick boxes). Attendees will leave with a clearer sense of how to spot insider risk early and translate guidance into actionable steps—especially in real-world, resource-constrained settings.
