The Case Study of Information Security System for International Airports

With continuing security concerns for airport operations, the protection of internal operational protocols of an international airport has become more critical than ever before. Therefore, the Information Security System (ISS) was developed for Incheon International Airport which can protect the critical information related to airport operations. The developed ISS includes a document access control server/client agent, a user access control service linker, and an operational log file database. The ISS was developed in consideration of information life cycle of airport workflow. As a result, it can securely protect the computer system at Incheon International Airport by (1) performing realtime encoding of the users who accessed the protected files and folders, (2) limiting the user's capability to edit the protected documents, (3) tracking transmitted files to the outside companies, (4) blocking the user's access to portable storage devices, and (5) inserting security water marks on the printed outputs. With the implementation of the ISS, the real-time information system audit environment has been securely established at the Incheon International Airport Corporation.
