Many IT professionals still use the term AS/400. But can a platform that was introduced in 1988 still be relevant today? The answers typically surprise people.

Many of us have heard that you can’t get a virus on this platform, but the reality is that the integrated file system (IFS) is a tree-like structure. This structure can house Word documents, PDFs, MP3s, JPEG images, and these files can be just as infected on the IBM i server as they can on any Windows work station or server.

It's true that IBM i can't be infected by a PC virus. It's also true that the IFS can act as a host and spread malicious programs throughout your environment.
