CIA triad versus Parkerian Hexad

If you find a really outrageous quote about infosec, it usually comes from either Donn Parker or Winn Schwartau. (If you find a really good quote about infosec, it usually comes from Gene Spafford or Bruce Schneier.) Donn frequently makes the point that the widely used CIA triad (Confidentiality, Integrity, and Availability) is insufficient to describe the totality of what we need to consider in the infosec field, and proposes a "hexad" of confidentiality, possession, integrity, authenticity, availability, and utility.

(Note also that Donn asserts the definitions of integrity and authenticity in the Wikipedia entry are flawed.)

NAME

       WebService::CIA::Source::DBM - An interface to a DBM copy of the CIA World Factbook

SYNOPSIS

	 use WebService::CIA::Source::DBM;
	 my $source = WebService::CIA::Source::DBM->new({
							  DBM  => 'factbook.dbm',
							  Mode => 'read'
							});

DESCRIPTION

       WebService::CIA::Source::DBM is an interface to a pre-compiled DBM copy of the CIA World Factbook.

       The module can also be used to make the DBM file, taking data from WebService::CIA::Parser (or WebService::CIA::Source::Web) and inserting
       it into a DBM.

       A script to do this - webservice-cia-makedbm.pl - should be included in this module's distribution.

METHODS

       Apart from "new", these methods are normally accessed via a WebService::CIA object.

       "new(\%opts)"
	   This method creates a new WebService::CIA::Source::DBM object. It takes a hashref of options. Valid keys are "DBM" and "Mode".

	   DBM is mandatory and should be the location of the DBM file to be used.

	   Mode is optional and can be either "read" or "readwrite". It defaults to "read".

       "value($country_code, $field)"
	   Retrieve a value from the DBM.

	   $country_code should be the FIPS 10-4 country code as defined in <https://www.cia.gov/library/publications/the-world-factbook/appen-
	   dix/appendix-d.html>.

	   $field should be the name of the field whose value you want to retrieve, as defined in <https://www.cia.gov/library/publica-
	   tions/the-world-factbook/docs/notesanddefs.html>.  (WebService::CIA::Parser also creates four extra fields: "URL", "URL - Print", "URL
	   - Flag", and "URL - Map" which are the URLs of the country's Factbook page, the printable version of that page, a GIF map of the coun-
	   try, and a GIF flag of the country respectively.)

       "all($country_code)"
	   Returns a hashref of field-value pairs for $country_code or an empty hashref if $country_code isn't in the DBM.

       "set($country_code, $data)"
	   Insert or update data in the DBM.

	   $country_code should be as described above.

	   $data is a hashref of the data to store (as Field => Value).

	   "set" overwrites any data already in the DBM under $country_code.

       "dbm()"
	   Returns a reference to the DBM file in use.
