+Configuration of grsecurity features via sysctl is possible in
+"/etc/sysctl.d/05-grsecurity.conf".
+
+Trusted Path Execution is disabled by default and can be enabled via the
+kernel.grsecurity.tpe sysctl option. The tpe group can be used either to build
+a whitelist for users free from the restrictions (tpe_invert = 1) or a
+blacklist of users with the restrictions (tpe_invert = 0).
+
+To prevent certain socket access to users, there are three groups:
+socket-deny-server, socket-deny-client and socket-deny-all.
+
+There is an extensive wikibook on grsecurity and some documentation in the
+Parabola GNU/Linux-libre Wiki:
