How secure is your connection to your Oracle Mobile Cloud or Integration Cloud service? In order to answer that question, Oracle ACE Associate Maarten Smeets, senior integration consultant with AMIS Services, suggests in his latest 2 Minute Tech Tip that you look at the various layers in the Open Systems Interconnection (OSI) model. Maarten explains that the data layer and segment or transport layer are particularly important. "The hardware layers are taken care of by Oracle since ICS and MCS are PaaS solutions. For security in the data layer you often see the use of Secure Token Services. Authentication takes place by a client and a token is returned. This token can be used for subsequent authentications and can be validated against the secure token service. Examples of this are SAML, JWT, and OAuth." Watch Maarten's tip for more detail.
