Configuring TLS for the management API

Edge for Private Cloud v4.18.01

By default, TLS is disabled for the management API and you access the Edge management API over HTTP by using the IP address of the Management Server node and port 8080. For example:

http://ms_IP:8080

Alternatively, you can configure TLS access to the management API so that you can access it in the form:

https://ms_IP:8443

In this example, you configure TLS access to use port 8443. However, that port number is not required by Edge - you can configure the Management Server to use other port values. The only requirement is that your firewall allows traffic over the specified port.

To ensure traffic encryption to and from your management API, configure the settings in the /opt/apigee/customer/application/management-server.properties file.

In addition to TLS configuration, you can also control password validation (password length and strength) by modifying the management-server.properties file.

Ensure that your TLS port is open

The procedure in this section configures TLS to use port 8443 on the Management Server. Regardless of the port that you use, you must ensure that the port is open on the Management Server. For example, you can use the following command to open it:

iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -j ACCEPT --verbose

Note: This example uses port 8443 for the TLS port, and not the more common port 443. The reason is that ports below 1024 are typically protected by the operating system and require the process that accesses them to have root access. The Edge Management Server runs as the "apigee" user and therefore typically does not have access to ports below 1024.

One alternative it to use a load balancer with the Edge API and terminate TLS on the load balancer on port 443. You can then use either HTTP or HTTPS between the load balancer and the Edge API.

Another alternative is to use iptables to forward requests to port 443 to port 8443. For example:

iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8443

Configure TLS

Edit the /opt/apigee/customer/application/management-server.properties file to control TLS use on traffic to and from your management API. If this file does not exist, create it.

Use the following procedure to configure TLS access to the management API:

Generate the keystore JKS file containing your TLS certification and private key. For more see Configuring TLS/SSL for Edge On Premises.
Copy the keystore JKS file to a directory on the Management Server node, such as /opt/apigee/customer/application.
Change ownership of the JKS file to apigee:
```
chown apigee:apigee keystore.jks
```
where keystore.jks is the name of your keystore file.

Edit /opt/apigee/customer/application/management-server.properties to set the following properties. If that file does not exist, create it:

conf_webserver_ssl.enabled=true
# Leave conf_webserver_http.turn.off set to false
# because many Edge internal calls use HTTP.
conf_webserver_http.turn.off=false
conf_webserver_ssl.port=8443
conf_webserver_keystore.path=/opt/apigee/customer/application/keystore.jks
# Enter the obfuscated keystore password below.
conf_webserver_keystore.password=OBF:obfuscatedPassword
conf_webserver_cert.alias=apigee-devtest

where keyStore.jks is your keystore file, and obfuscatedPassword is your obfuscated keystore password. See Configuring TLS/SSL for Edge On Premises for information on generating an obfuscated password.

Restart the Edge Management Server by using the command:

/opt/apigee/apigee-service/bin/apigee-service edge-management-server restart

The management API now supports access over TLS.

Configure the Edge UI to use TLS to access the Edge API

In the procedure above, Apigee recommended leaving conf_webserver_http.turn.off=false so that the Edge UI can continue to make Edge API calls over HTTP.

Use the following procedure to configure the Edge UI to make these calls over HTTPS only:

Configure TLS access to the management API as described above.
After confirming that TLS is working for the management API, edit /opt/apigee/customer/application/management-server.properties to set the following property: conf_webserver_http.turn.off=true

Restart the Edge Management Server by using the command:

/opt/apigee/apigee-service/bin/apigee-service edge-management-server restart

Edit /opt/apigee/customer/application/ui.properties to set the following property for the Edge UI. If that file does not exist, create it: conf_apigee_apigee.mgmt.baseurl="https://FQDN:8443/v1" where FQDN is the full domain name, as per your certificate address of the Management Server, and the port number is the port specified above by conf_webserver_ssl.port.
Only if you used a self-signed cert (not recommended in a production environment) when configuring TLS access to the management API above, add the following property to ui.properties: conf/application.conf+play.ws.ssl.loose.acceptAnyCertificate=true Otherwise, the Edge UI will reject a self-signed cert.

Restart the Edge UI by using the command:

/opt/apigee/apigee-service/bin/apigee-service edge-ui restart

TLS properties for the Management Server

The following table lists all of the TLS/SSL properties that you can set in management-server.properties:

Properties	Description
`conf_webserver_http.port=8080`	Default is 8080.
`conf_webserver_ssl.enabled=false`	To enable/disable TLS/SSL. With TLS/SSL enabled (true), you must also set the ssl.port and keystore.path properties.
`conf_webserver_http.turn.off=true`	To enable/disable http along with https. If you want to use only HTTPS, leave the default value to `true`.
`conf_webserver_ssl.port=8443`	The TLS/SSL port. Required when TLS/SSL is enabled (`conf_webserver_ssl.enabled=true`).
`conf_webserver_keystore.path=<path>`	The path to your keystore file. Required when TLS/SSL is enabled (`conf_webserver_ssl.enabled=true`).
`conf_webserver_keystore.password=`	Use an obfuscated password in this format: OBF:xxxxxxxxxx
`conf_webserver_cert.alias=`	Optional keystore certificate alias
`conf_webserver_keymanager.password=`	If your key manager has a password, enter an obfuscated version of the password in this format: OBF:xxxxxxxxxx
`conf_webserver_trust.all= <false \| true>` `conf_webserver_trust.store.path=<path>` `conf_webserver_trust.store.password=`	Configure settings for your trust store. Determine whether you want to accept all TLS/SSL certificates (for example, to accept non-standard types). The default is `false`. Provide the path to your trust store, and enter an obfuscated trust store password in this format: OBF:xxxxxxxxxx
`conf_webserver_exclude.cipher.suites=<CIPHER_SUITE_1 CIPHER_SUITE_2>` `conf_webserver_include.cipher.suites=`	Indicate any cipher suites you want to include or exclude. For example, if you discover vulnerability in a cipher, you can exclude it here. Separate multiple ciphers with a space. For information on cypher suites and cryptography architecture, see: http://docs.oracle.com/javase/8/docs/technotes/guides/security/SunProviders.html#SunJSSE
`conf_webserver_ssl.session.cache.size=` `conf_webserver_ssl.session.timeout=`	Integers that determine: The TLS/SSL session cache size (in bytes) for storing session information for multiple clients. The amount of time TLS/SSL sessions can last before they time out (in milliseconds).
