Is AFS a secure file sharing protocol?
AFS is a secure service if it is configured properly via file permissions and access control lists. If you would like the UNIX group to review the permissions currently on your AFS space, they will be happy to do so. AFS is a Global file system and therefore anyone can read files with the permission system:anyuser, anywhere in the world. You can further secure your data by encrypting it on AFS space or even password protecting the file. The UNIX group can assist with doing that for you as well.
