This is a quick introduction to Step 2 of the Risk Management Framework NIST 800-37 process. Step 2 involves selection of NIST Special Publication 800-53 security controls. There are (3) main tasks that you must do in this step:
1) Select the applicable baseline controls. Selection of baseline controls is based on system categorization.
2) Tailor the Security Controls to the system. Not all security controls can be used because they may break your system. And in some cases they are simply not applicable. There are also Common Controls, Hybrid controls, and system specific controls.
3) Document the Security Controls. You must document the selected security controls in a system security plan and have the security controls reviewed.
