The number of credentials Requirements-to-Obtain Elements developed since 2002 is, to some extent, the result of the flurry of legislation resulting from the terrorist attacks of September During the application process, the issuing agencies require 11, 2001. Security credentials became the regulatory method of those seeking to obtain a security credential to submit various effecting access control. types of information (e.g., name, address, Social Security Num- ber). These requirements to obtain were gathered through the individual applications and organized into several matrices to Credential Categorization illustrate overlap or uniqueness among the various security credentials. These matrices were grouped by transportation Credentials were then categorized based on their primary mode to aid in identifying common requirements.

Additionally, two of the requirements are applicable both a means of security and safety (i.e., the CDL-HME and to 91% of the identified credentials: place of birth (not appli- MMC). The HazMat endorsement for the CDL requires a cable to the CDL-HME) and fingerprinting (not applicable to threat assessment (14), thus vetting the credential-holder from the passport).

Table 3-3 groups all background-check processes into the security threat assessment category. This was done to simplify the table for comparison purposes. However, this is an impor- tant aspect of the security credentials, especially with regard to duplication of effort and redundant costs (refer to the cost analysis section). Table 3-3 specifies the background check processes for each credential. The fingerprint-based criminal records check refers to the background check performed by the Federal Bureau of Inves- tigation (FBI) using the National Crime Information Center (NCIC). Regardless of the issuing agency, the FBI performs this portion of the investigation and then provides the relevant data to the issuing agency (or adjudicating organization). A name-based investigation of relevant databases includes non- fingerprint criminal history record checks (e.g., U.S. passport), and a review of the Terror Watch List (e.g., TWIC, MMC, and HME) maintained by DHS. This could also include other data- Figure 3-2. Credential bases as the issuing agency may deem fit for a given circum- categorization. stance. The MMD requires a drug test as part of the application
