Automated File Integrity Monitoring with Slack Alerts

This n8n workflow automates the daily monitoring of critical server files by calculating their SHA256 checksums via SSH, comparing them to known baseline values, and sending instant Slack alerts if any files are modified. The process is scheduled with a cron trigger, making it ideal for IT teams, DevOps, and sysadmins to proactively detect unauthorized changes, malware, or attacks. The workflow involves scheduling, checksum calculation, comparison, and alerting, providing a cost-effective, reliable security layer that ensures the integrity of your infrastructure without manual effort.
