Hi everyone. Jen here. We've been migrating a lot of our backend infrastructure to AWS, and a key project was securing our RDS instances. While Cloud One has a strong reputation, I wanted to document the actual setup process for real-time file integrity monitoring and threat detection, as I found the practical steps less discussed than the high-level features.
Our goal was to monitor critical system directories on our RDS (PostgreSQL) instances for unauthorized changes. The Cloud One – Workload Security agent was the tool, but the trick is in the policy configuration. Here's the core of what we did after deploying the agent via the AWS Systems Manager (which was straightforward).
First, in the Workload Security console, we created a dedicated policy for RDS. The critical rule was under "Prevention" -> "Integrity Monitoring". We set a real-time scan rule targeting specific paths like `/rdsdbdata/` (where our data lives) and key system binaries. The alert threshold was set to "Real-Time" and configured to send events directly to our Slack ops channel via the Cloud One event forwarding. This gave us immediate visibility.
A few things to watch for: ensure your IAM roles for Systems Manager have the correct permissions for the agent installation, and double-check the network access rules so the agent can communicate back to the Trend Micro console. We also had to fine-tune the integrity monitoring rules to avoid alert fatigue from normal, expected changes during our scheduled maintenance windows.
I'm curious if others have gone through a similar setup. What paths did you find most critical to monitor? Did you run into any latency concerns with the real-time alerts, or have tips for managing the policy across a fleet of heterogeneous databases?
