Bill C-8 and the Critical Cyber Systems Protection Act: What It Means for Canadian Organizations
February 11, 2026Tabletop Exercises: Rehearsing the Bad Day Before It Arrives
February 25, 2026The cloud rarely fails; the settings do
Most cloud incidents we investigate do not come from an exotic exploit. They come from a setting that was left open, a permission that was too broad, or a resource that no one remembered existed. The cloud is secure by design, but it is not secure by default for your specific use, and that gap is where trouble lives.
The usual suspects
- Public storage buckets and databases exposed to the internet.
- Over-permissioned identities and long-lived access keys with far more rights than they need.
- Disabled logging, so no one can see what happened after the fact.
- Forgotten resources spun up for a test and never shut down.
- Default credentials or unrestricted management interfaces.
Why misconfigurations pile up
Cloud environments change constantly. Developers move fast, infrastructure is created by code, and a single template can replicate a mistake across dozens of resources in seconds. Without guardrails, small errors scale as quickly as the platform itself.
Controls that actually help
- Apply least privilege and prefer short-lived credentials over standing access keys.
- Turn on logging and monitoring everywhere, and make sure someone reviews the alerts.
- Use automated configuration checks to catch drift before attackers do.
- Define secure infrastructure-as-code baselines so the safe choice is the default.
- Run periodic reviews of identities and public exposure, and remove what is no longer used.
Ownership matters
Cloud security runs on a shared responsibility model. The provider secures the platform; you secure how you use it. Confusion about that boundary is itself a common root cause. Make it explicit who owns configuration, access, and monitoring in your environment so nothing falls through the cracks.
Takeaway
The most damaging cloud breaches usually trace back to ordinary misconfigurations, not sophisticated attacks. Least privilege, always-on logging, automated configuration checks, and clear ownership will prevent the majority of them.
