Our company is moving several workloads to AWS while keeping sensitive data on-premise. I'm worried about "configuration drift" and maintaining consistent security policies across both environments. What tools or frameworks do you recommend for centralized visibility and ensuring that our hybrid setup doesn't leave any backdoors open for attackers?

Make sure you are using a unified logging solution like a SIEM. You need to correlate events from your on-prem firewalls with AWS CloudTrail logs to see the full picture of an attack.
The biggest risk in hybrid cloud is often the lack of a "single pane of glass." You should implement a Cloud Security Posture Management (CSPM) tool that supports both your on-prem and AWS environments. This helps you detect misconfigurations in real-time. Also, adopt Infrastructure as Code (IaC) for your deployments. By using tools like Terraform or CloudFormation with embedded security checks, you ensure that every environment is built according to the same hardened template. This significantly reduces the risk of human error and helps maintain compliance across the board.
Are you more concerned about the data in transit between the two sites, or the identity management between your local Active Directory and AWS IAM? Both are huge targets for lateral movement if not handled correctly.
Daniel, the identity sync is our biggest headache right now. For that, we found that using an Identity Provider that supports SCIM for automated provisioning is a lifesaver. It ensures that when someone leaves the company, their access is revoked everywhere simultaneously, which is a major security requirement for us.
Definitely, Ryan. Correlation is the only way to detect a threat actor moving from a cloud-facing app into the on-prem database. Consistency in logging is vital.
