Synonym for "Defense Password Management Guideline" [CSC2].

Deprecated Term: Except as an explanatory appositive, IDOCs SHOULD NOT use this term, regardless of the associated definition. Instead, use the full proper name of the document or, in subsequent references, a conventional abbreviation. (See: Rainbow Series.)

Deprecated Usage: To improve international comprehensibility of Internet Standards and the Internet Standards Process, IDOCs SHOULD NOT use "cute" synonyms. No matter how clearly understood or popular a nickname may be in one community, it is likely to cause confusion or offense in others. For example, several other information system standards also are called "the Green Book"; the following are some examples:

  • Each volume of 1992 ITU-T (known at that time as CCITT) standards.

  • "PostScript Language Program Design", Adobe Systems, Addison- Wesley, 1988.

  • IEEE 1003.1 POSIX Operating Systems Interface.

  • "Smalltalk-80: Bits of History, Words of Advice", Glenn Krasner, Addison-Wesley, 1983.

  • "X/Open Compatibility Guide".

  • A particular CD-ROM format developed by Phillips.
