Line of Business

 – The following OMB-defined process areas common to virtually   all federal agencies: Case Management, Financial Management,   Grants Management, Human Resources Management, Federal   Health Architecture, Information Systems Security, Budget   Formulation and Execution, Geospatial, and IT Infrastructure.   SOURCE: SP 800-53 114   “Lines of business” or “areas of operation” describe the purpose of   government in functional terms or describe the support functions that   the government must conduct in order to effectively deliver services   to citizens. Lines of business relating to the purpose of government   and the mechanisms the government uses to achieve its purposes tend   to be mission-based. Lines of business relating to support functions   and resource management functions that are necessary to conduct   government operations tend to be common to most agencies. The   recommended information types provided in NIST SP 800-60 are   established from the “business areas” and “lines of business” from   OMB’s Business Reference Model (BRM) section of Federal   Enterprise Architecture (FEA) Consolidated Reference Model   Document Version 2.3   SOURCE: SP 800-60 Link Encryption – Link encryption encrypts all of the data along a communications path   (e.g., a satellite link, telephone circuit, or T1 line). Since link   encryption also encrypts routing data, communications nodes need to   decrypt the data to continue routing.   SOURCE: SP 800-12   Encryption of information between nodes of a communications   system.   List-Oriented – Information system protection in which each protected object has a   list of all subjects authorized to access it.
