Most security configuration takes place on the <%=vars.product_name%> server. The server's security
framework authenticates clients as they connect to a cache server and authorizes client cache
operations using developer-provided implementations for authentication and authorization.

For an explanation of the server-side implementation of security features, 
see [Security](<%=vars.serverman%>/managing/security/chapter_overview.html) in the *<%=vars.product_name%> User Guide*.

A Native Client application must address two security concerns when connecting to a <%=vars.product_name%> server: 

-   **[Authentication](authentication.html)**

    The Client must submit its authentication credentials to the server using the developer-provided authentication implementation expected by the server.

-   **[TLS/SSL Client/Server Communication Encryption](sslclientserver.html)**

    Communication between client and server should be encrypted so authentication credentials and other transmissions cannot be viewed by third-parties.
