In August of this year, there was a bunch of panic about GitHub being compromised, and 35K repos having malicious code in them. Further investigation clarified that it was Github Repos that were set up to do a “phishing” type attack, by creating repositories that were improperly named or Typosquatting. That being said it has led to further discussion and attention around Code Supply Chain, and ensuring that code contributions, libraries and releases are validated before use.

Introduction The File Integrity Operator is used to watch for changed files on any node within an OpenShift cluster. Once deployed and configured, it will watch a set of pre-configured locations and report if any files are modified in any way that were not approved. This operator works in sync with MachineConfig so if you update a file through MachineConfig, once the files are updated, the File Integrity Operator will update its database of signatures to ensure that the approved changes do not trigger an alert.
