Secure your MAP platform

This chapter describes advanced procedures to secure your Centreon MAP platform.

Configure HTTPS/TLS on the web server

HTTPS/TLS configuration with a recognized key

This section describes how to add a recognized key to the Centreon MAP server.

If you want to create an auto-signed key and add it to your server, please refer to the following section

You will require:

• A key file, referred to as key.key.
• A certificate file, referred to as certificate.crt.

Access the Centreon MAP server through SSH.

Create a PKCS12 file with the following command line:

openssl pkcs12 -inkey key.key -in certificate.crt -export -out keys.pkcs12

Then, import this file into a new keystore (a Java repository of security certificates):

keytool -importkeystore -srckeystore keys.pkcs12 -srcstoretype pkcs12 -destkeystore studio.jks

Put above keystore file (studio.jks) to the folder "/etc/centreon-studio/", and set below parameters inside /etc/centreon-studio/studio-config.properties:

centreon-map.keystore=/etc/centreon-studio/studio.jks
centreon-map.keystore-pass=xxx

Replace the keystore-pass value "xxx" with the password you used for the keystore and adapt the path (if it was changed) to the keystore.

HTTPS/TLS configuration with an auto-signed key

Enabling the TLS mode with an auto-signed key will force every user to add an exception for the certificate before using the web interface.

Enable it only if your Centreon also uses this protocol.

Users will have to open the URL:

https://<MAP_IP>:8443/centreon-studio/api/beta/actuator/health.

The solution we recommend is to use a recognized key method, as explained above.

On the Centreon MAP server, create a keystore.

Go to the folder where Java is installed:

cd $JAVA_HOME/bin

Then generate a keystore file with the following command:

keytool -genkey -alias studio -keyalg RSA -keystore /etc/centreon-studio/studio.jks

The alias value "studio" and the keystore file path /etc/centreon-studio/studio.jks may be changed, but unless there is a specific reason, we advise keeping the default values.

Provide the needed information when creating the keystore.

At the end of the screen form, when the "key password" is requested, use the same password as the one used for the keystore itself by pressing the ENTER key.

Put above keystore file (studio.jks) to the folder "/etc/centreon-studio/", and set below parameters inside /etc/centreon-studio/studio-config.properties:

centreon-map.keystore=/etc/centreon-studio/studio.jks
centreon-map.keystore-pass=xxx

Replace the keystore-pass value "xxx" with the password you used for the keystore and adapt the path (if it was changed to the keystore).

Activate TLS profile of Centreon MAP service

1. Stop Centreon MAP service:

   systemctl stop centreon-map

2. Edit the file /etc/centreon-studio/centreon-map.conf, adding ",tls" after "prod" profile:

   RUN_ARGS="--spring.profiles.active=prod,tls"

3. Restart Centreon MAP service:

   systemctl start centreon-map

Centreon MAP server is now configured to respond to requests from HTTPS at port 8443.

To change the default port, refer to the dedicated procedure.

Don't forget to modify the URL on Centreon side in Map server address field in Administration > Extensions > Map > Options menu.

Configure TLS on the Broker connection

An additional Broker output for Centreon Central (centreon-broker-master) has been created during the installation.

You can check it in your Centreon web interface, from the Configuration > Pollers > Broker Configuration, by editing the centreon-broker-master configuration.

The output configuration should look like this:

Broker configuration

You can enable TLS output and set up Broker's private key and public certificate as described below:

"Trusted CA's certificate" field is optional. If you activate Broker's client authentication by setting this "ca_certificate.crt", then you must setup a keystore for MAP server

You MUST push the new broker configuration and restart the broker after configuration.

MAP server configuration

First of all, you should activate HTTPS/TLS on the web server

Then, set the following parameter in MAP server configuration at /etc/centreon-studio/studio-config.properties to enable TLS socket connection with Broker :

broker.tls=true

Configuration with a self signed certificate

If the Broker public certificate is self signed, you must create a trust store containing given certificate or its CA certificate with the following command line:

keytool -import -alias centreon-broker -file broker_public.crt -keystore truststore.jks

• "broker_public.crt" is Broker public certificate or its CA certificate in PEM format,
• "truststore.jks" is the generated trust store in JKS format,
• a store password is required during generation.

Then, put the generated output file "truststore.jks" into "/etc/centreon-studio" of MAP server host.

And add truststore parameters in /etc/centreon-studio/studio-config.properties:

centreon-map.truststore=/etc/centreon-studio/truststore.jks
centreon-map.truststore-pass=XXXX

Replace the trustStorePassword value "xxx" with the password you used when generate the trust store.

Meanwhile, you should activate the "tls_broker" profile of Centreon MAP service.

Edit the file /etc/centreon-studio/centreon-map.conf, and replace ",tls" by ",tls_broker" after "prod" profile:

RUN_ARGS="--spring.profiles.active=prod,tls_broker"

"tls_broker" profile implies "tls" profile. So Centreon MAP service serves necessarily HTTPS.

Configuration with a recognized CA certificate

If the broker public certificate is signed with a recognized CA, the JVM default trust store "cacerts (/etc/pki/java/cacerts)" will be used. Nothing to configure for Centreon MAP service
