Hello,

the command cat /proc/$LOGSTASH\_PID/environ can tell about the logstash keystore password since it's a an environment variable (LOGSTASH\_KEYSTORE\_PASS)

Is there a way to secure this password ?  
Thank you

No. If you have access to the Logstash process there's currently no way to keep the keystore password secret.
