NIST SP800 53R4 WMISACA Conferance April 2016 By Dean E Brown CISSP, ISSMP, CSSLP, MCSD Owner – ITSecurityAxioms.com 262 Barrington Cir Lansing, MI

Agenda Ground Level 0 (Zero) = What is NIST (Really Fast) Basics 101 – Controls By The Section / Number (Spreadsheet) Specific Application (Beware the Minimum) References

What Is NIST? - 1 National Institute of Standards and Technology is a USA Federally sponsored agency. They set the standards that all other agencies have to follow. Federal Information Processing Standard Publication (FIPS) 199, Standards for Security Categorization of Federal Information and Information Systems, and FIPS Publication 200, Minimum Security Requirements for Federal Information and Information Systems.

What is NIST? – 2 FIPS "Federal Information Processing Standard" / FIPPS "Fair Information Practice Principles (FIPPs)" Introductory Reading, Should be required; Summary of NIST SP Revision 4.

What is NIST – 3? FIPS 200 and NIST Special Publication , in combination, ensure that appropriate security requirements and security controls are applied to all federal information and information systems. An organizational assessment of risk validates the initial security control selection and determines if additional controls are needed to protect organizational operations (including mission, functions, image, or reputation), organizational assets, individuals, other organizations, or the Nation. The resulting set of security controls establishes a level of security due diligence for the organization. OK so if you are going down the NIST SP r4 path, you have to put FIPS 200 in your backpack. This presentation is NOT about FIPS 200. I will come back to that in section 3.

Basics Risk Based Framework Divided into 3 Catagories Control Familes Uses Priorities Considered the defacto standard

Basics Key quote that you need to embrace: “the security controls and control enhancements listed in the initial baselines are not a minimum— but rather a proposed starting point from which controls and controls enhancements may be removed or added.”

Basics Doing this in slides is hard to wrap your mind around. It is easier to think in spreadsheets. In the main document there are some really great appendix pieces. DO NOT IGNORE THEM!

Basics NIST is the defacto standard. From SANS NewsBites February 23, 2016 Vol. 18, Num. 015 OPM CIO and Inspector General Out. Appropriate Accountability At Last. (February 22, 2016) The chief information officer of the U.S. Office of Personnel Management (OPM) quit today, under pressure, two days before she was due to testify before a Congressional panel. She was responsible for cybersecurity programs at OPM that followed NIST guidance but did not implement and measure the Critical Security Controls, which are widely recognized as the minimum standard of due care. Her resignation follows the resignation of the OPM Inspector General (IG) who was equally responsible for forcing the agency to follow guidelines (from OMB and NIST) that documented the cybersecurity gaps but did not close those gaps. Bold added for clarity.

Specific Application – 1 Work / Practice Sessions Example Practice Session

Specific Application – 2 Beware the Minimum from FIPS 200 (2006 is the last published edition as of DANGER - Your Regulators will use more current standards. Specifically, NIST Special Publication covers the steps in the Risk Management Framework that address security control selection for federal information systems in accordance with the security requirements in Federal Information Processing Standard (FIPS) 200.)
