I was expecting the article by Chris Wright, Stephen Smalley et al. about Linux Security Modules https://www.usenix.org/legacy/event/sec02/wright.html. We running out of acronyms space in computer science. :-)

I'm glad I've been deceived into reading the article though, very interesting topic.

First link within the text (the link to wikipedia) is broken. It has "s" where it should have "https".
