#SSL

5

Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client - typically a web server (website) and a browser, or a mail server and a mail client.

Learn more.

Hi community,

I would like to ask how to correctly enforce SSL on all "developer traffic" -- that is Management portal and Studio connections -- on a Caché instance.

Given large developer permissions, I would like to eliminate all plaintext credentials on the wire.

Currently, we compile our own httpd with SSL support for Management portal, but this breaks Add-Ins for us, in particular the SOAP wizard. So I guess this is not the "canonical way".

Thanks for any suggestions

Jiri

Adding TLS to ZAUTHENTICATE

I wrote a ZAUTHENTICATE.mac a couple of months back, and found recently that it is creating coredumps on almost a nightly basis. I think I have figured out this problem to be not clearing out my MsgSearch after I am doing 2 of them within the code.

1. Get User Attibutes from AD

2. Get User Groups From AD

So while I am trying to cleanup the code I thought it would be a good time to add a Certificate and TLS to the mix since I should of been using that all along. However I keep running into issues

TCP adaptor + SSH Tunnel

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

I was thinking that Ensemble could maintain the SSH tunnel,

which would improve our detecting of issues.

Has anyone done something like this?

I see that the class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself. Instead, it appears

Upgrading TLS configurations

Caché will not change the cryptographic settings in an existing TLS configuration when you upgrade. This means that unless you've updated them yourself, you're still using the values from the very first version you started using SSL in.

I have an Ensemble installation and just build my first RestService (using %CSP.Rest that forwards them to my Business Service). This works nice and fine when I use postman to make REST calls over http (port 57772). However when I attempt to make a request using https over port 443 I receive the following error:

I have an Ensemble installation with an FTP business operation which I would like to connect to a server over SSL in explicit mode (see also: https://www.rebex.net/kb/tls-ssl-explicit-implicit/default.aspx). I keep running into timeouts while attempting to do this via Ensemble. Does Ensemble actually support SSL in explicit mode??? Because I can't seem to find any setting where to switch it on.

Hi,

I can't work out how to use the Cache CA Server to process certificate request from external clients!

We are setting up an interface where we use SSL/TLS 'Mutual Authentication' to allow a client system to securely transmit document to our server. (they are off-site and hosting a service for us)

I am not a security expert, but my understanding of setting up mutual authentication where my instance of ensemble is the server, and it is receiving messages from a client is as follows

We are in the process of setting enabling SSL on a soap web service exposed via InterSystems, but are running into trouble. We have installed our certificates on our webserver (Apache 2.4) and enabled SSL over the default port 57772. However, we now get an error when sending a soap message to the web service (it used to work over http). Specifically the CSP gateway refuses to route te emssage the soap web service:

I have built an Ensemble SOAP service (EnsLib.SoapService.Service) as a business service which accepts soap requests from another application. To secure the traffic between the SOAP service and the application i'd like to enable SSL. I see that in the management portal I can upload the certificates, chains and keys and save them as an SSL / TLS configuration. However, it is not clear to me how I apply this SSL / TLS configurtion to the soap service I am running.

Atelier over https

Can Atelier connect to an Ensemble server that only accepts https connections?

How do I configure that? I did try an ssh into such server and Atelier over that but it didn't seem to work.

Any suggestions?

Thanks,

Chris

TLS Cipher Suite selection

Our client is a test out of 2016.1 (Build 656U) Healthshare that wants to do a one way SSL connection to our Java 1.7/Tomcat 8.0 server. We have yet to come up with a secure cipher set that Healthshare and Java agree on for the handshake. So far we've had to use these ciphers identified which are not recommended (though it does do a handshake properly).

I have posted to aid others in diagnosing problem with SSL/TLS connections to superserver port from .NET client executable.

The cache instance this appeared on is quite old - 2011 - so I do not know if Intersystems have added a better error message in a later version

The actual fault was due to the certificate in the %SuperServer SSL/TLS configuration having expired.

The unhelpful message that appeared in the .NET client included the following partial stack trace.

openssl for Windows

Question:

Where can I find the openssl command line tool for Windows?

Answer:

The openssl command line utility comes with Unix, but not with Windows. It is used for working with security certificates.

The main site is

https://www.openssl.org/

There are no binaries on this site but in the Community section there is a link for binaries which leads to:

I am using OAuth2 Cache framework, acting as a client to an authorization server. My setup is based on this excellent previous post [Caché Open Authorization Framework (OAuth 2.0) implementation – part 1].

I'm facing ‘Authorization Server Error: Error Processing Response - No match between server name 'googleapis.com' and SSL certificate values google.com…’

It looks like I should set SSLCheckServerIdentity to false but I can’t figure out how. Has anyone had the same issue?

Hi,

I'm posting this for the benefit of others. Not often one changes certificates in Cache, at least in my case. I run a system, that uses certificates to encrypt SOAP messages, and since the last time I ran it, my certificates expired.

So I renewed them using our PKI tool, so far so good. I gave all (3) certificates the same names (and filenames too) as to those expired, thinking that everything would just work fine next time I call the SOAP service.

Unfortunately, I got trapped.
