@mobdata/classy v1.0.1

classy

Module for comparing intelligence community classifications.

Install

Testing

npm install --save '@mobdata/classy'

Usage

The module exports several functions which makes testing them easier but most everyone will only need one, the bannerEqOrMoreSecureThan.

Given two classification strings, or "banners", this function returns true when the first banner is at least secure as the second banner.

In a prototypical example, you have a document classified as "SECRET" and person X has asked to see it. Person X's clearance gives them access to "CONFIDENTIAL" information. In this case, Person X does not have the clearance to view the document! Their clearance is not "equal or more secure than" the document's classification.

import { bannerEqOrMoreSecureThan } from '@mobdata/classy';

var document = 'SECRET';
var personX = 'CONFIDENTIAL';

if (bannerEqOrMoreSecureThan(document, personX) === true) {
  // do something cool
} else {
  // don't let personX see it!
}

Additional notes about bannerEqOrMoreSecureThan:

• The parameters are case-insensitive.
• The parameters may be of arbitrary complexity.
• The parameters may be any accepted banner line marking found in the "Marking of Classified Information" manual 5200.01, Volume 2 for the DoD.
• This includes classifications, disseminations and any number of sci's.
• Abbreviations such as found in portion markings, S//REL, C//FRD, etc, are not supported.
• Not supported: non-U.S. documents markings, joint classification markings, Atomic Energy Act markings.
