SSL query

ah so by best practice, following the naming convention even not needed for now is the best way. it will be future proof in case they decided to make the application available online. make sense.

If they make it available online, and the URL changes, then you'll need to re-issue the SSL Certificate. But otherwise, you are right.

Hi,
I'm new on SSL and have some questions. I have a project that is an application accessible via web browser. the application will only be accessible within office LAN.
the application vendor wanted as SSL so that all data in & out of the server are encrypted. So we get an SSL even we feel we dont actually need just to get this over with. since the application is within LAN, what domain name should i use when configuring the SSL in the IS server? is that going to be the local IP address of the server?
I want to check here as my vendor will most likely ask us to register a domain name. it looks like the vendor is following a checklist based on a online web application instead of our plan of going an internal LAN application.
It is still a good idea to use SSL even local services.
Do you have a typical MS domain setup?
If yes, do you have any public domains listed in DNS?
If so, just make a new subdomain as a CNAME record to the internal server name and get the SSL on that.
If you do not already have a public domain on your internal DNS it can be a more complicated decision from a "how do I want to manage this overall" point of view, but the technical process is the same.

@JaredBusch this is my first time handling this so sorry if i sounded newbie. what do you mean typical domain setup? also, what you mean public domains listed in DNS?

Start at the beginning.
Do you have a Windows domain based network? This is not something that is not known.
-
yes we have domain based network. for the public listed domains, we have a lot. each server carries its own naming convention and didnt follow the main company domain name.

A public domain is something like mangolassi.it or bundystl.com You have those on your internal DNS?
-
i will need assistance to check it on our internal DNS. let me check.

i only have 3 entries there as well, same as your screenshot.

Then you can make a new subdomain for one of them such as PBX in this example.
Then you can go to the app server and generate the CSR and use a service like StartSSL to get a free 1 year SSL certificate for it.
I would recommend LetsEncrypt but if there is no outside facing part to this, that is more work than it is worth. Just renew once a year with StartSSL and be done.

free from startssl is a very good idea, instead of paying for a year on SSL for internal network.
-
thank you very much jared and dafyre

I don't trust startssl to be secure at all tho, you can get a google.com cert without much problem. It's annoying because they somehow got included as a valid certificate provider.
Stick with Let's Encrypt for free certs.

I've used StartSSL for years. What is wrong with the service?

Looks like they did resolve the one I was thinking of. http://www.securityweek.com/startssl-flaw-allowed-attackers-obtain-ssl-cert-any-domain
Generally just a very lackadaisical take on security, half their answers to vulnerabilities are "Yeah, we know about that, it's not a problem."

Hmm I learn a lot on this SSL project. The IIS, SSL and even read some about Comodohacker..interesting...

This is a host name, not a subdomain. A subdomain would be like Omaha.nebraska.com where Omaha is a subdomain that has its own hosts listed, i.e. dodge.omaha.nebraska.com where dodge is the host name.

What's the difference? It's both a subdomain and a hostname.

Well I was going to ask if in my example Omaha. nebraska.com could point to an IP, but then I thought about that, and yes... I know that nebraska.com can point to an IP, soooo why not omaha.nebraska.com?
