Sending a clear text secret is not secure. The eXtreme Scale security infrastructureprovides a SecureTokenManager plug-in to allow the server to secure this secretbefore sending it. You can choose how you implement the secure operation.WebSphere eXtreme Scale provides an implementation, in which the secureoperation is implemented to encrypt and sign the secret.Java Management Extensions (JMX) security in a dynamicdeployment topologyJMX MBean security is supported in all versions of eXtreme Scale. Clients ofcatalog server MBeans and container server MBeans can be authenticated, and50IBM WebSphere eXtreme Scale: Administration Guide April 2012
access to MBean operations can be enforced.Local eXtreme Scale securityLocal eXtreme Scale security is different from the distributed eXtreme Scale modelbecause the application directly instantiates and uses an ObjectGrid instance. Yourapplication and eXtreme Scale instances are in the same Java virtual machine(JVM). Because no client-server concept exists in this model, authentication is notsupported. Your applications must manage their own authentication, and then passthe authenticated Subject object to the eXtreme Scale. However, the authorizationmechanism that is used for the local eXtreme Scale programming model is thesame as what is used for the client-server model.Configuration and programmingFor more information about configuring and programming for security, see“Security integration with external providers” on page 503 and Security API.Planning for installationBefore you install the product, you must consider software and hardwarerequirements and Java environment settings.Hardware and software requirementsBrowse an overview of hardware and operating system requirements. Althoughyou are not required to use a specific level of hardware or operating system forWebSphere eXtreme Scale, formally supported hardware and software options areavailable on the Systems Requirements page of the product support site. If aconflict exists between the information center and the System Requirements page,the information at the website takes precedence. Prerequisite information in theinformation center is provided as a convenience only.See the System Requirements page for the official set of hardware and softwarerequirements.You are not required to install and deploy eXtreme Scale on a specific level ofoperating system. Each Java Platform, Standard Edition (Java SE) and JavaPlatform, Enterprise Edition (Java EE ) installation requires different operatingsystem levels or fixes.You can install and deploy the product in Java EE and Java SE environments. Youcan also bundle the client component with Java EE applications directly withoutintegrating with WebSphere Application Server. WebSphere eXtreme ScalesupportsJava SE 5 or later and WebSphere Application Server Version 6.1 and later.
