Adding an HTTP Port
The HTTP port enables API Gateway to authenticate the client and server securely and exchange the data. In addition, you can configure the type of client authentication that you want the server to perform. Client authentication allows you to verify the identity of the client.
*To add an HTTP port
1. Expand the menu options icon , in the title bar, and select Administration.
2. Select Security > Ports.
The ports page lists all the ports configured with API Gateway, if any.
3. Click Add ports.
4. Select the type of port as HTTP and click Add.
5. Provide the following information:
Field
Description
HTTP listener configuration. Provide the following details to configure the HTTP listener set up.
Port
Specify the number you want to use for the port.
Select a number that is not already in use on this host machine.
Alias
Specifies an alias for the port that is unique for this API Gateway.
An alias must be between 1 and 255 characters in length and include one or more of the following: letters (a -z, A-Z), numbers (0-9), underscore (_), period (.), and hyphen (-).
Description (optional)
Provide a description of the port.
Bind address (optional)
Specifies the IP address to which to bind this port.
Specify a bind address if your machine has multiple IP addresses and you want the port to use this specific address. If you do not specify a bind address, API Gateway picks one for you.
Backlog
Specifies the number of requests that can remain in the queue for an enabled port before API Gateway begins rejecting requests.
The default is 200. The maximum value is 65535.
Keep alive timeout
Specifies when to close the connection if the server has not received a request from the client within this timeout value (in milliseconds) or when to close the connection if the client has explicitly placed a close request with the server.
Private threadpool configuration. Specifies whether to create a private thread pool for this port or use the common thread pool.
Enable
Select to enable the private threadpool configuration for this port.
Threadpool min
Specifies the minimum number of threads for this private threadpool. The default value is 1.
Threadpool max
Specifies the maximum number of threads for this private thread pool. The default value is 5.
Thread priority
Specifies the Java thread priority. The default value is 5.
Security configuration . Provide the following details to configure security parameters.
Client authentication
Specifies the type of client authentication you want API Gateway to perform for requests that arrive on this HTTPS port.
Select one of the following:
*Username/Password. API Gateway does not request client certificates. The server looks for user and password information in the header of requests coming from an external client.
*Digest. API Gateway uses password digest to authenticate all requests. If the client does not provide the authentication information, API Gateway returns an HTTP WWW-Authenticate header with digest scheme to the client requesting for authentication information. If the client provides the required authentication information, API Gateway verifies and validates the request.
*Request kerberos ticket. API Gateway looks for a Kerberos ticket in the HTTP Authorization header using the Negotiate authentication scheme. If it does not find the ticket, API Gateway uses username and password for basic authentication. If the client does not provide any authentication information, API Gateway returns an HTTP WWW-Authenticate header with negotiate scheme to the client requesting for authentication information. If the client provides the required authentication information, API Gateway verifies and validates the request.
*Require kerberos ticket. API Gateway looks for a Kerberos ticket in the HTTP Authorization header using the Negotiate authentication scheme. If it does not find the ticket, API Gateway fails the authentication. If the client does not provide any authentication information, API Gateway returns an HTTP WWW-Authenticate header with negotiate scheme to the client requesting for authentication information. If the client provides the required authentication information, API Gateway verifies and validates the request.
You have to enable Kerberos by providing the following Kerberos properties with details that are used for handling service requests that come with a Kerberos ticket:
*JAAS context. Specify the custom JAAS context used for Kerberos authentication.
*Principal. Specify the name of the principal to use for Kerberos authentication.
*Principal password. Specify the password for the principal to use to authenticate the principal to the KDC.
*Retype principal password. Retype the principal password.
*Service principal name. Specify the name of the principal used with the service that the Kerberos client wants to access.
Note:
API Gateway supports the username format for Service Principal Names (SPNs). This format represents the principal name as a named user defined in LDAP used for authentication to the KDC.
6. Click Add.
The port is created and is listed in the ports table.
Important:
The default access mode of the port is set to Allow by default. This implies that the port allows connections to all ESB services and folders, which in turn, increases the risk of exposing all enterprise assets hosted in internal Integration Server. Also, the risk is higher when the IS assets are secured by Anonymous Access Control Lists (ACL) or if the installation is exposed to the public internet. Hence, to avoid any potential security risk, you can set the access mode of the port to Deny by default before enabling it. When you change the access mode, you add the required services and folders to the Allow list. For more information, see Configuring Access Mode for a Port.
Also, the global IP access mode will be applied to the newly created HTTP ports. You can modify the IP access mode as per your requirement. For information on modifying IP access mode of ports, see Configuring IP Access Mode for a Port.
7. Click the icon in the Enabled column next to the port to enable the port.
The port is enabled and a success message appears.
