Security Best Practices

This section outlines some security best practices to consider when using KeyView.

  • Keep KeyView Up to Date. New releases may include security updates, including updates to third-party libraries. See Third-Party Library Upgrade Policy.
  • Run KeyView with Minimal Privileges. In the event that a malicious actor causes KeyView to behave dangerously, the potential damage is limited if KeyView is running with fewer privileges. See Run Filter with Minimal Privileges.
  • Run Filter Out-of-Process. By default, Filter processes documents in a separate process, which protects the stability of the calling application. OpenText strongly recommends that you use this default.

  • Sanitize absolute paths when extracting subfiles. Container files can specify paths that point outside the extract directory, which can lead to a type of path traversal vulnerability known as Zip Slip. KeyView automatically sanitizes relative paths to prevent this, but OpenText recommends that you also configure KeyView to sanitize absolute paths. See Sanitize Absolute Paths.
