[jira] Updated: (DERBY-1056) Print a security warning to derby.log and network server console if network server is started with remote connections enabled and security manager, user authentication, and ecrypted userid are not on

     [ http://issues.apache.org/jira/browse/DERBY-1056?page=all ]

Kathey Marsden updated DERBY-1056:
----------------------------------

        Summary: Print a security warning to derby.log and network server console if network server is started with remote connections enabled and security manager, user authentication, and ecrypted userid are not on  (was: Print a security warning to derby.log and network server console if network server is started with -h 0.0.0.0 and security manager, user authentication, and ecrypted userid are not on)
    Description: 
Information and questions from the user list seem to indicate that often users enable remote connections by starting  network server with the -h 0.0.0.0  or -h <machinename> option without taking proper security measures.    I think it would be worthwhile to print a security warning the console and derby.log if network server is starated without the proper security in place.

Serious security issues exist when starting network server and allowing remote connections unless users:

- Run in security manager with permissions restricted as much as possible.
- Enable user authentication
- Use encrypted userid/password (Currently only available with IBMJCE)
-  Maybe also print a warning if bootPassword is sent in the connectionAttributes, since this cannot be encrypted.  (I had thought there was a jira issue for this but can't find it.)

Even when started with the localhost default there can be security  issues  if the machine itself is not secure.

An example of such an attack might include creating databases  until the host machine disk filled up, deleting all user data etc.

DERBY-474

Dan pointed out that this needs to print when remote connections are enabled with -h <machinename> as well so changing the title.

I also thought of one other warning needed if bootPassword is passed in the connection attributes, so added that to the description.

Also Dan  asked me to elaborate about security issues  when Network Server is  started on localhost.  Mostly these arise from shared machines  where  users do not trust each other,  for example the District Attourney  and the Public Defender share a machine and  have separate databases  but  these are accessesed through network server.     The same risks apply because  the users of the machine do not trust each other.   The D.A. might set up  his database and user authentication  for the database  and think he is all set, but really the password is being sent CLEAR_TEXT and the public defender might be able to gain access.  
 The D.A might even think he could set up a bootPassword, but that  has two problems 1) The bootPassword is sent in the connection attributes and so is always sent clear text and 2) once the database is booted the public defender has access.

Perhaps this type of risk is just obvious, but because we don't  start up with connections restricted in anyway as they might be with other database servers, users may not realize the risk.

Some of these issues were discussed in this thread:

http://www.nabble.com/DRDA-Password-Encryption-%28SECMEC_EUSRIDPWD-and-SECMEC_USRENCPWD%29-t80296.html#a24266

At that time David suggested making a top level Client/Server Security Issue which is not a bad idea, but we actually have not had much luck executing on other such important top level issues as DERBY-310 and DERBY-209.  Since this one is security it might gain more attention.  I don't know.
