1. Set the following parameter in /etc/sysctl.conf or a /etc/sysctl.d/* file: kernel.randomize_va_space = 2
2. Edit the /etc/bashrc, /etc/profile and /etc/profile.d/*.sh files (and the appropriate files for any other shell supported on your system) and add or edit any umask parameters as follows: umask 027
