Security

This page discusses deployment topology and advanced configuration that will allow you to secure your Genesys Mobile Services solution. Note: Although some load balancing considerations are discussed on this page with respect to solution architecture, configuration recommendations are provided on the Apache Load Balancer page.

Overview of Security, Access Control, and Load Balancing

Genesys Mobile Services makes contact center functionality accessible through a set of REST- and CometD-based APIs. Since these APIs can be used both by clients residing inside and outside the enterprise network, it is important to understand how to protect data that is travelling between solution components. The Genesys Mobile Services solution is designed to work with your existing security infrastructure, relying on third-party components (security proxies) to provide encryption and authorization capabilities.

Deployment requirements

Genesys Mobile Services should always be deployed behind an HTTP security gateway (proxy) performing:

client authentication (optional)
TCP port and URL access control
load balancing functionality, distributing the load between multiple Genesys Mobile Services nodes responsible for processing API requests
HTTP connection encryption (SSL)

In addition, the HTTP security gateway (proxy) could perform following functions:

protect against denial of service (DoS) attacks
authenticate requests using HTTP Basic/Digest, oAuth or other authentication/authorization protocol
manage client access using IP-based access control
rate limit API traffic using quotas
inspect packets for threats and sensitive data

Genesys Mobile Services Deployment Topology

The following image shows architecture and communication links between different components in a normal Genesys Mobile Services solution. A table with recommendations on how to secure these connections follows immediately after.

**List of Connections Utilized by a Typical Genesys Mobile Services Deployment**
Server Component	Connection #	Client Type	API/Function	Transport	Server: Port, Configuration	Client Configuration	Security Recommendations
Security Gateway and Load Balancer in Front of Genesys Mobile Services Nodes (Customer Client Side)	(1)	User/customer facing application inside or outside of the corporate firewall: mobile, web or ... based application	Cometd based notification, Chat, Service and Storage APIs exposed through Genesys Mobile Services component	HTTP/HTTPS	Any deployment-specific port convenient for client applications. For example: 80. See third party gateway/proxy documentation if you need to change/configure this port. See also GMS->Options->/server/external_url_base configuration option in Configuration Manager	Client is typically a hard-coded server port as part of the API access URL	Client applications should access Genesys Mobile Services APIs through SSL-protected HTTP connections with optional basic/digest/oAuth/... client authentication. If a client application has no access to user credentials, then anonymous access is supported but will result in a lower level of security. Clients should be blocked from accessing certain URLs of the API according to the access rules below.
Security Gateway and Load Balancer in Front of Genesys Mobile Services Nodes (Agent Client Side)	(2)	Agent-facing application inside or outside of the corporate firewall: mobile, web or ... based application	CometD-based notification, Chat, Service and Storage APIs exposed through Genesys Mobile Services components	HTTP/HTTPS	Any deployment-specific port convenient for client applications. For example: 81 See also GMS/server/external_url_base configuration option in Configuration Manager. Note: Use a different port from connection (1).	Client is typically a hard-coded server port as part of the API access URL.	Agent applications residing outside of the enterprise intranet can also access Genesys Mobile Services APIs through an SSL-protected HTTP connection. Agent authentication can be performed against Configuration Server, or other service such as LDAP, by the security gateway. Deployments with lower security requirements can allow API access without agent authentication, relying only on uniqueness of the service ID supplied by the application. In this case, it is assumed that only trusted applications would gain access to service ID. Agent authentication is encouraged especially if used outside of the corporate network. Clients should be blocked from accessing certain URLs of the API according to the access rules below.

Customer Facing API Access Rules for Security Gateway in Front of Genesys Mobile Services

The following access rules should be used as a model for your environment, allowing a list of services provided by your Genesys Mobile Services deployment to be accessed while restricting the use of internal-only services. Note: Only allow access to the limited set of services listed by name.

 Allow:
 {base url:port}//genesys/cometd 
 
 {base url:port}/genesys/{version}/service/{service name}
 {base url:port}/genesys/{version}/service/{id}
 {base url:port}/genesys/{version}/service/{id}/request
 
 {base url:port}/genesys/{version}/storage/{ttl}
 {base url:port}/genesys/{version}/storage/{data id}/{ttl}
 {base url:port}/genesys/{version}/storage/{data id}

Mobile Native Push Notification Configuration Details

Two major mobile platforms are currently supported: Android and Apple. Details about Genesys Mobile Services configuration could be found on the Push Notification Service page of the API Reference.

Client Side Port Definitions for Genesys Framework Connections

The following connections support client side port definition functionality:

Connection to Configuration Server - This port definition is defined as part of the installation, and as an environment variable.
HTTP Connections between Genesys Mobile Services nodes – This port definition is defined as part of the configuration data associated with the Genesys Mobile Services Application object, and is used to create the connections between Genesys Mobile Services nodes.
HTTP Connection from Genesys Mobile Services to ORS – This port definition is defined as part of the configuration data associated with the Genesys Mobile Services Application object and is used to create the connection with ORS.
Genesys Mobile Services to Chat Server Connections - this port definition is defined as part of the configuration data associated with the Genesys Mobile Services application object and is used to create the connection with Chat Server.

Note: Connections from client applications (CometD and REST API requests) do not have client side port definitions.

Hiding Sensitive Data in Logs

Genesys recommends using log data filtering to hide sensitive configuration data in log files. The given product will then use that filter to determine what content should be filtered or masked when creating log files. The only real interface to Genesys Mobile Services are APIs, and having to configure filter criteria every time you add a new parameter or API is cumbersome and complicated. Therefore, Genesys Mobile Services supports filtering and masking data in log files for any API parameter that matches the following naming convention:

Filter: Any parameter name that is prefixed with XXX will be filtered out of the log files entirely. Example: XXX_FilterParam
Mask: Any parameter name that is prefixed with MMM will be masked in the log files, showing in the log with the letters MMM. Example: MMM_MaskParam

Protecting Data Stored in the Cassandra Database

The <Genesys Mobile Services installation directory>/etc/cassandra.yaml file enables or disables encryption of Cassandra inter-node communication using TLS_RSA_WITH_AES_128_CBC_SHA as the cipher suite for authentication, key exchange, and encryption of the actual data transfers. To encrypt all inter-node communications, set to all. You must also generate keys, and provide the appropriate key and trust store locations and passwords. Details about Cassandra options are available from:

All transient service session-related data is stored in a Cassandra database that uses memory and the file system. See the <Genesys Mobile Services installation directory>/data folder. Files located here should be protected from unauthorized access.

Configuring SSL Connection Listener for a Jetty Container

Beginning with Jetty 7.3.1, the preferred way to configure SSL parameters for the connector is by configuring the SslContextFactory object and passing it to the connector's constructor. Jetty has two SSL connectors–the SslSocketConnector and the SslSelectChannelConnector. The SslSocketConnector is built on top of the Jetty SocketConnector which is Jetty's implementation of a blocking connector. It uses Java's SslSocket to add the security layer. The SslSelectChannelConnector is an extension of Jetty's SelectChannelConnector which uses non-blocking IO. For its security layer, it uses java nio SslEngine. You can configure these two connectors similarly; the difference is in the implementation. The following is an example of an SslSelectChannelConnector configuration. You can configure an SslSocketConnector the same way, just change the value of the class to org.eclipse.jetty.server.ssl.SslSocketConnector.

 <Call name="addConnector">
    <Arg>
      <New class="org.eclipse.jetty.server.ssl.SslSelectChannelConnector">
        <Arg>
          <New class="org.eclipse.jetty.http.ssl.SslContextFactory">
            <Set name="keyStore"><SystemProperty name="jetty.home" default="." />/etc/keystore</Set>
            <Set name="keyStorePassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
            <Set name="keyManagerPassword">OBF:1u2u1wml1z7s1z7a1wnl1u2g</Set>
            <Set name="trustStore"><SystemProperty name="jetty.home" default="." />/etc/keystore</Set>
            <Set name="trustStorePassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
          </New>
        </Arg>
        <Set name="port">8443</Set>
        <Set name="maxIdleTime">30000</Set>
      </New>
    </Arg>
 </Call>

Choosing a Directory for the Keystore

The keystore file in the example above is given relative to the Jetty home directory. For production, choose a private directory with restricted access to keep your keystore in. Even though it has a password on it, the password may be configured into the runtime environment and is vulnerable to theft. You can now start Jetty the normal way (make sure that jcert.jar, jnet.jar and jsse.jar are on your classpath) and SSL can be used with a URL like: https://localhost:8443/

Setting the Port for HTTPS

Remember that the default port for HTTPS is 443 not 80, so change 8443 to 443 if you want to be able to use URLs without explicit port numbers. For a production site it normally makes sense to have an HttpListener on port 80 and a SunJsseListener on port 443. Because these are privileged ports, you might want to use a redirection mechanism to map port 80 to 8080 and 443 to 8443, for example. The most common mistake at this point is to try to access port 8443 with HTTP rather than HTTPS.

Redirecting HTTP requests to HTTPS

To redirect HTTP to HTTPS, the webapp should indicate it needs CONFIDENTIAL or INTEGRAL connections from users. This is done in web.xml:

 <web-app>
 ...
 <security-constraint>
   <web-resource-collection>
     <web-resource-name>Everything in the webapp</web-resource-name>
     <url-pattern>/*</url-pattern>
   </web-resource-collection>
   <user-data-constraint>
     <transport-guarantee>CONFIDENTIAL</transport-guarantee>
   </user-data-constraint>
 </security-constraint>
 </web-app>

Then you need to tell the plain HTTP connector that if users try to access that webapp with plain HTTP, they should be redirected to the port of your SSL connector (the "confidential port"):

 <Call name="addConnector">
  <Arg>
     <New class="org.eclipse.jetty.nio.SelectChannelConnector">
        ...
        <Set name="confidentialPort">443</Set>
     </New>
  </Arg>
 </Call>
