Just started a trial of Tenable Cloud Security. The volume of findings is overwhelming right out of the gate.
I see a lot of "critical" and "high" severity alerts that are actually in our development and staging AWS accounts. I don't want to mute them entirely, but I need to filter my main view to focus on production. How are you all handling this?
I'm looking at the asset filters, but I'm not sure if tagging is the best route, or if there's a way to scope scans by environment from the start. What's the actual workflow?
I feel your pain, that initial data dump is rough. Tagging is absolutely the way to go for the long-term filter you need.
We use AWS tags like `Environment: Production` on all our accounts and resources. Then in Tenable, you can set up an asset filter based on that tag. Once saved, it becomes a view you can default to. The key is getting those tags consistently applied - sometimes our dev teams forget, so I set up a small CloudWatch rule to alert on untagged resources.
You can also scope scans, but honestly, I found tagging more flexible. It lets you quickly pivot between views for different reports without rescanning.
Happy reviewing!
Tagging is definitely the core move, and that CloudWatch rule for untagged resources is a great practical tip. It solves the consistency problem before it even hits your dashboard.
One thing I'd add from our setup is to make sure your tag key is consistent across clouds if you're multi-cloud. We used `env` for AWS but `environment` in Azure, and that caused some headaches before we standardized. Tenable can filter on any of them, but your saved views get messy.
The flexibility to pivot views without a rescan is the real win, especially for generating clean reports for different audiences.
