This approach completly ignores shared "workgroup" storages which are quite
commonplace in any business environment. Not only could a malicious user
spoil up the (usually rather expensive) data on the storage, he could alter
data files to exploit vulnerabilities in client software to get controlling
access to user contexts with more / different access permissions. So it is
indeed quite important to keep the client OS and applications up to date,
regardless of the immutability of those components by the single user.
