A document that regulates the security aspects of a proposed link between an agency and an external system. It regulates the security interface between two arbitrary systems operating under two different authorities. It contains a wide range of descriptive, technical, procedural and planning information. Generally, it is preceded by a formal MOA/MOU that defines higher roles and responsibilities in managing an inter-domain link. Source (s): CNSSI 4009-2015 In this manual, an agreement is reached between organizations that own and operate connected computer systems to document the technical requirements of interconnection. The ISA also supports a Memorandum of Understanding or Agreement (MOU/A) between the organizations. Source: NIST SP 800-47 as part of the Interconnection Security Agreement (ISA) An ISA is not required of any participant who transmits electronic data to CBP`s AES system only through any of the following methods: AES, ACAS and ITDS subscribers who connect directly to these CBP systems or via the SFTP, must: Instructions for the Electronic Interconnection Security Agreement (ISA) for the Trade Internet Virtual Private Network / Secure File Transport Protocol In accordance with the implementation of the Security Directive for Customs Information and Border Protection Systems (CBP) Subscribers who transmit electronic data directly to the Automated Export System (AES), Air Cargo Advanced Screening (ACAS), International Trade Data System (ITDS) or secure File Transport Protocol (SFTP) connection , must submit an Interconnection Security Agreement (ISA) signed to CBP. Below is information on identifying participants who need to submit an ISA, as well as instructions for completing and transmitting the ISA to CBP. If the above exclusion does not apply, you must make a direct link to CBP and complete and return an ISA document.
In the absence of ISA, CBP is prevented from creating the communication profile for transmission to AES, resulting in the removal of a pre-existing profile. When you complete the ISA, change the document to the following replacements: (With MS Word, the replacement clauses will all be highlighted and displayed either in bold or in large format. Comments on the presentation and functionality of the glossary should be sent to email@example.com. Comments on certain definitions should be sent to the authors of the related source publication. For NIST publications, there is usually an email in the document. . Connection security agreement for MPLS/MQ users.
