Monitor Remote Server File Integrity with SSH & Slack Alerts

This workflow provides a robust, automated solution for monitoring file integrity on remote servers. It runs on a customizable schedule (e.g., daily via Cron node), maintains a list of critical files and their baseline SHA256 checksums in a Code node, fetches current checksums from the server using SSH, compares them with an If node, and notifies via Slack if discrepancies are found—indicating potential tampering or corruption. If files are unchanged, it silently ends.

Key benefits include proactive security monitoring without manual intervention, reducing breach detection time from days to minutes, easy customization for any file paths or servers, and seamless integration with existing Slack channels for team alerts. It's ideal for compliance-heavy environments like finance or healthcare where file integrity is paramount.

Use cases: Securing configuration files, logs, or executables on Linux servers; auditing web app deployments; or ensuring no unauthorized changes in production environments. Scalable for multiple servers/files by extending the Code node's array, making it a time-saving essential for DevOps and IT security teams.
