A survey of interoperability in Enterprise Information Security Architecture frameworks

Recently, two major changes have taken place in the realm of enterprise information architecture. First, during the past six years the Enterprise Information Security Architecture (EISA) has found its place in Enterprise Architecture (EA) and has changed into an accepted industrial reference model. Following that, the enterprises have altered their strategies to support interoperability more strongly due to the increase of ICT opportunities. This change of strategy has engendered new risks and threats to the security of enterprise information. Supposedly, EISA frameworks should handle and manage these new challenges. This paper is going to answer the following question; have EISA frameworks taken the subject of interoperability into account or not.
