Functions

• Setup SELinux on amazon linuxc
• Format system according to a secure partitioning scheme. Limit log partition so it does not take down the rest of your system. Limit actions on mount points as much as possible.
• Examines the system for over 40 points from the NSA guidelines for securing RHEL
• Install varnish, mysql, and apache in chroot jails.

Steps to Execute Process Automatically

• Create new amazon linux server, M3.large
• Setup three drives, xvda with 24 GB, xvdb with 24 GB, and xvde with 960 GB
• Start server, log in, and set root password
• Execute from your machine: yes | batch_setup_server.sh
• Restart the server when all is said and done.

Steps to Demonstrate Entire Process Manually

• Create new amazon linux server, M3.large
• Setup three drives, xvda with 24 GB, xvdb with 24 GB, and xvde with 960 GB
• Start server and log in
• update server and restart (you need the updated kernel)
• Install git
• Clone this repository
• Execute: install.sh
• Execute: cd /var/lib/setup_script
• Execute: yes | ./setup_selinux.sh
• Execute: shutdown -r now
• Log in again
• Execute: yes | ./setup_partitions.sh
• Execute: shutdown -r now
• Log in again
• Execute: yes | ./setup_hardening.sh
• Execute: ./install_varnish_chroot.sh
• Execute: ./install_mysql_chroot.sh
• Execute: ./install_apache_chroot.sh
• You are all setup!

Greetings. Welcome to Setup Script.

DO THIS FIRST After unzipping the archive, run "./install.sh" to setup and configure these scripts.

This directory is useful for setting up a new server with basic scripts for installing, configuring firewalls, and hardening a server.

After setting up on the server, this directory may be deleted if you choose.

DIRECTORY CONTENTS Initial, setup scripts are directly in the directory.

Subdirectories:

• scripts: add_ftp.sh -- this adds an ftp user, based on our configuration
• samples: sample configuration, meant as starters for various services
• data: data used by different sections of the script

SYSTEM EFFECTS

install.sh:

• Creates and copies files from setup directory to /var/lib/setup_script
• Creates /var/run/setup_script to store temporary files for our scripts setup_all.sh:
• TODO
• Execute all setup scripts in the right order setup_selinux.sh:
• Modifies grub.conf and SELinux configuration
• Enables SELinux
• You should reboot after running this file, as other scripts assume SELinux setup_partitions.sh:
• Optional
• You should run this immediately after running setup, if you're going to run it at all
• Sets up partitions according to SETUP_DIR/data/partition_cmds.txt
• Generates filesystems in the new partitions according to SETUP_DIR/data/filesystem_generations_cmds.txt
• Adds new partitions to fstab based on fstab_template.txt setup_hardening.sh:
• TODO: FINISH
• May be run on a server in operation to harden security settings
• Currently tested for RHEL and Amazon Linux
• Completes most checkpoints of NSA hardening guide for RHEL
• Creates an undo script in its TMP_DIR that can undo most changes. install_all_scripts.sh:
• Install links for all scripts in LIB_DIR/scripts
• These are scripts you may want to run to manage the server during normal operation.
