14.1.3 ISO 27001 Application Service transactions and their controls . Based on the 2013 version and the new control definition I think Its no longer about e commerce, but a more wider application service banner.
Please let me know what is "Application Service transactions" means. I tried doing some googling didnt get much.
Application Service transactions means generally any transaction that involves the interchange of information through a network between 2 applications, for example, as you know e-commerce, but also financial transactions between banks, or between a entity with a bank; transactions of database (for example, 2 database that are synchronizing information through Internet); or a ERP that is connected with an externa site where send or receives information.
Anyway, remember that here is not necessary to have a specific document for this control, if you want to know the list of mandatory documents required by ISO 27001:2013, please read this article List of mandatory documents required by ISO 27001 (2 013 revision) : https://advisera.com/27001academy/knowledgebase/list-of-mandatory-documents-required-by-iso-27001-2013-revision/
