SQL Server – Can only certain SQL users be forced to use TLS?

My school wants to develop custom software for some embedded devices. In this context, we may need the devices to connect to a SQL Server instance.

Is it possible to force certain SQL users to use encryption when connecting to the server? We do not want to enforce it on the whole instance because it's an important piece of older software.

We also evaluate other (honestly better) solutions, but I want to know what's possible.

Decryption of TLS / SSL traffic With the debug file from Fiddler on Wireshark

I want to decrypt some packages on Wireshark. When I search the Internet, some people say that they are using the SSLKEYLOGFILE environment. I do that, but it looks like the choir will not update this file when I visit my landing page.

By the way, somewhere I am familiarizing myself with Fiddler and find out that it creates a cert file and does some things to decrypt only the https message. I want to know where Fiddler's debug file is and how to give the wireshark to decrypt the packages it contains.

TLS: Cant Connect For LDAP

I use version 3.16 of Free Radius. I have a scenario where I connect to an AD server with TLS enabled. Everything is working well. Now I change my server to LDAP with non-TLS. I see that it still tries to do TLS before LDAP and fails.

tls – Need help understanding the following terms when creating a .pfx file for SSL installation on Windows IIS Server

Please refer to my previous question here

With general knowledge of the SSL installation I need to understand the following, especially in terms of wild guesswork:

The error "Can not load private key" and "Expect: ANY PRIVATE KEY" indicates that the key you specified is not a private key. What exactly the reason for that can not be deducted from the information, but here are some wild guesses:

– You have not seen that privateKey.key is a placeholder and your file has a different name.

– You did not change to the correct working directory where the certificate and the private key were located.

– You used your public key instead of your private key.

– You do not have correct permissions for your private key.

-Your private key does not have a recognized format (eg, newline gadgets)

I have to understand the five above hints.

Secure Store Service Application SharePoint 2013 can not be deployed. A TLS error is displayed

I can not deploy the Secure Store Service application for SharePoint 2013. A TLS error is displayed. Below is the error:

tls – I get the error message "Your connection is not private" and it disappears when I use a VPN

I am using a Mac (with macOS Sierra). Yesterday I watched a movie online from a less trusted website, and when I clicked the pause button, a tab appeared and suddenly disappeared.

If I open an https site from that moment on, an error will be output with the name "Your connection is not private", It Not No matter if I use Chrome, Safari or Mozilla Firefox, everything from them throw the same mistake. When I recently opened Google, a tab opened with the following URL: Gstatic.com/generate_204 by itself!

The interesting thing is when I use it gate or if I use a VPN and change my location somewhere else, All websites are starting to work!, Why is this happening?

Things that I have tried:

1) Check the date and time – they are all correct.

2) deleted my cache and restarted my computer and browser.

3) I tried to find unwanted installed apps or extensions on my Chrome that I did not install – I could not find any.

Could someone PLEASE give some help! I'm scared to death because my Mac has found a virus and all my credit card information is in danger!

https – How is it possible that TLS certificates issued to cloudflare.com work on other unrelated domains?

How is it checked?
I thought there are only three ways to validate trusted certificates:
Domain, organization and expanded.

How is it different from self-signed certificates if the certificate was not even issued for the domain?

I do not understand how a certificate can be issued, for example, for stackexchange.com and still appear safe when used with facebook.com

tls – What are the security precautions for using a TPM-generated VSC to create a CSR?

I'm new to information security, but I've received a project to create a secure TLS certificate signed by our CA for a new security process. I found this thread (How do I create a unique and non-duplicable VPN certificate / VPN key for a particular client hardware device?) It seems to be an answer to my problem.

Is this a secure way to create a certificate?

What are the protective measures when using a VSC?

And the line in the above process " attestation AIK_AND_CERT", what is the purpose of this?

TLS Handshake: No response to Client Hello from TLS1.0 Windows XP client

First me knows TLS1.0 is bad, but I have no choice but to support it – we can not control the client end, and if a large percentage of the clients are not supported, it would be a disadvantage for us head Competitive disadvantage for this project.

I'm not an SSL / TLS / etc expert, but I think I have an idea of ​​how it should work.

I have written a service that runs on a Windows 10 computer over https with a self-signed SSL certificate. This works fine if (of course) all clients explicitly trust this certificate or are configured to not validate the server certificate. Usually this will support TLS 1.1 and 1.2, but for the purposes of this test, I have limited it to Only 1.0

Some clients for this service are running Windows XP (the specific client I need to test with is Windows XP Embedded SP2, but can not specify that this will be used for all XP clients).

I used NetMon to capture a network trace.

I think it's a negotiating problem with the cipher suite.

As a test, I have an old version of FireFox installed on the XP machine and thus established a connection. This works fine, but as I understand FF uses its own TLS stack, so obviously an encryption suite can be arranged, but at least excludes other network problems or problems with my service.

I use IISCrypto View / modify related content on my Windows 10-based computer.

I used NetMon to capture and see traces Customer Hello Messages from these older clients, but no Hello server In answer.
I can see that the client is sending a list of (older) cipher suites, the third of which is TLS_RSA_WITH_3DES_EDE_CBC_SHAThat's one that I am appear to have in my list

I have used IISCrypto Enable this encryption suite on my Windows 10 computer and rearrange the list so that it appears at the top. However, this has not made a difference. It is possible for me added This was added to the list with IIS Crypto, but was not sure at the time (studied it for several days).

When I create a TLS 1.0 client and run it locally on my computer, it works fine.

My best guess is that one of the components of the cipher is not properly set up / present … Can anyone suggest what I can change that can help?

Many Thanks.

tls – change the SSL certification path

When connecting to a resource using SSL, I know that the certificates can be validated by the client to make sure the connection is secure.

I've recently had problems with SSL at work when connected to my company's network (using a specific Wi-Fi endpoint only). There were no issues using the Web browser, but when connecting to Curl or Java, errors such as "Issue with SSL certificate: Self-signed certificate in certificate chain" or "PKIX path setup failed, valid certification path not found to requested destination." I checked the certification path in the browser and found that the entire certification path of the website was replaced by certificates from my company, but this was only the case for certain websites, other websites such as Google or Microsoft amazon was still loaded with the right certificates.

Now I have some questions for you. How is it possible to change all certificates? Why is my browser not complaining about it? Does anyone know why this only happens for certain websites? I work in a very large company and still have not found the right person to talk to.
