Yes for a single host.
However, once one has networked hosts then one must also consider
using cryptographic mechanisms to maintain per-user separation for
data in transit between the networked systems. If one lacks such
separation on networked hosts, then it is not feasible to provide
per-user separation of data on the hosts themselves because the data
might be compromised whilst transiting the network. It is the latter
problem that is being discussed in the context of IPv4 and IPv6
security.
