+# This file is disabled by default. It provides a few kernel
+# hardening settings. This file is automatically updated.
+# 
+# Please read the Fedora hardening page for further information
+# about this file (section 'Fedora-maintained (self-updating)
+# hardening for general and average use cases' and
+# section 'Fedora-maintained self-updating kernel hardening'):
+#   https://docs.fedoraproject.org/en-US/security/topics/hardening
+#
+# If you want to enable the hardening, please create a symlink:
+#   sudo ln -s /usr/share/doc/systemd/99-kernel-hardening.conf /etc/sysctl.d/
+# -> do NOT copy or move or hardlink this file because
+# this would break the automatic updates!
+#
+# Enabling this file can cause issues to some software developers:
+# the need to use ptrace is restricted in the hardening
+# because of the security issues it may cause in some
+# circumstances: to use applications like gdb or strace when the
+# hardening is enabled, users need to temporarily enable ptrace
+# during the runtime of their ptrace-dependent application.
+# Enabling ptrace implies disabling yama.ptrace_scope (which is
+# the security measure enabled below).
+# You can enable temporarily ptrace with:
+#   sysctl kernel.yama.ptrace_scope=0
+# You can subsequently disable it again with:
+#   sysctl kernel.yama.ptrace_scope=2 
+# -> it will be reset automatically after reboot.
+# For more information, read the Fedora hardening page
+# mentioned above.

+# their upstream and other useful documentation
