Steve Loughran commented on HADOOP-9621:
----------------------------------------
# the doc is still there, you just need to request read access
# someone could export it from google docs to .md and then for site;
illustrations would have to go in as png files. Be nice if the plantuml
(presumably) spec files were in source too, for maintenance
> Document/analyze current Hadoop security model

> In light of the proposed changes to Hadoop security in Hadoop-9533 and
> Hadoop-9392, having a common, detailed understanding (in the form of a
> document) of the benefits/drawbacks of the current security model and how it
> works would be useful. The document should address all security principals,
> their authentication mechanisms, and handling of shared secrets through the
> lens of the following principles: Minimize attack surface area, Establish
> secure defaults, Principle of Least privilege, Principle of Defense in depth,
> Fail securely, Don’t trust services, Separation of duties, Avoid security by
> obscurity, Keep security simple, Fix security issues correctly.
