examine hardening, fix and update documentation as needed

[mmguero]

It's been a bit since I went through the hardening scripts for the ISO installers and examined the output

• Malcolm - Hardening
• Hedgehog - Hardening

Need to:

• verify that the hardening scripts are installed and run correctly
• go through the issues, compare them with the list of exceptions in the documentaiton
• make any fixes that should be fixed in the ISO environments
• update any documentation that needs to be updated

Initial runs:

• hardening_malcolm.txt
• hardening_sensor.txt
