Is there a provision for virus protection?

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

How does the repository is protected?

There is no virus scan by default. Here are some solutions:

• HTTP Virus Scanner
  /> Some Virus Scanners can scan HTTP requests. They are usually plugged at the reverse proxy level.
  /> * Advantages
  /> Transparent to application layer.
  />User has a feedback when he tries to upload a corrupted file.
  /> * Drawback
  />If the Virus Scanner is slow, everything will be slow.
• Synchronous Virus Scanner
  /> If your virus scanner can be called from Java or from the command line, then you can easily add inside Nuxeo a synchronous listener that will execute the virus scan.
  /> In case of virus the listener should:
  />- mark the Transaction as Rollback,
  />- raise an Exception.
  /> * Advantages
  /> User has a feedback when he tries to upload a corrupted file.
  /> * Drawback
  /> If the Virus Scanner is slow, everything will be slow.
  /> You have to write a listener.
• Asynchronous Virus Scanner
  /> If your virus scanner can be called from Java or from the command line, then you can easily add inside Nuxeo an asynchronous listener that will execute the virus Scan.
  /> In case of virus the listener should:
  />- remove the attached file,
  />- add an audit log entry stating the file was removed because of a virus detection.
  /> * Advantages
  /> No performance impact
  /> * Drawback
  /> You have to write a listener.
  /> User is not directly notified.
  /> The corrupted file was stored and accessible for some time.
• Filesystem scanner
  /> You can also let your virus scanner watch the directory tree used by the Repository Binary Store. Note you must restrict the virus scanner to that specific directory, not the whole Nuxeo directory or it will drastically decrease the performances and even may break Nuxeo (under Windows OS)
  /> In case of virus the corrupted file will be removed.
  /> * Advantages
  /> No performance impact.
  /> No code
  /> * Drawback
  /> The user will never know why the file was removed! The corrupted file was stored and accessible for some time.
