by Kristy Westphal Sept. 1, 2017 via Symantec

Why is it that when you read almost any book or paper about Solaris security it will explicitly say: turn off the NFS and NIS services.

Security issues seem to be inherent in their structure; however, there are methods and precautions that can be taken to make them more secure than their plain-vanilla implementations.
