How do you confirm TLS 1.2 is enabled?
Click on: Start -> Control Panel -> Internet Options 2. Click on the Advanced tab 3. Scroll to the bottom and check the TLS version described in steps 3 and 4: 4. If Use SSL 2.0 is enabled, you must have TLS 1.2 enabled (checked) 5.
TLS 1.2 is enabled by default. Therefore, no change to these keys is needed to enable it. You can make changes under Protocols to disable TLS 1.0 and TLS 1.1 after you've followed the rest of the guidance in these articles and you've verified that the environment works when only TLS 1.2 enabled.
Verify TLS (or SSL) inspection is working
Sign in to a Chrome device with a user account in the domain where the certificate was applied. Go to a site where TLS inspection is applied by your web filter. Verify the building icon is in the address bar. Click it to see details about permissions and the connection.
- Open Microsoft Edge.
- Click on Settings.
- Click on System.
- Click on Open your computer's proxy settings.
- In the search bar, type Internet options and press Enter.
- Select the Advanced tab.
- Scroll down to Security category and tick the box for Use TLS 1.2.
- Click OK.
- - Click on Internet Options.
- - Click on the Advanced tab and scroll all the way to the bottom.
- - Make sure that "Use TLS 1.2" is check and then hit OK. This will enable TLS 1.2 on the computer and allow the user to access OnBoard through IE and Edge.
- Different ways to check TLS version your instance is using:
- 1) Curl command:
- A) TLS1.0 --> curl -v -s --tlsv1.0 https://<instance-name>.service-now.com/stats.do -o /dev/null/ 2>&1.
- B) TLS1.1 --> curl -v -s --tlsv1.1 https://<instance-name>.service-now.com/stats.do -o /dev/null/ 2>&1.
| Browser | TLS 1.2 Supported (Not enabled by default) | Enabled by default |
|---|---|---|
| Microsoft Edge | All Versions | |
| Google Chrome | Version 29 | Version 29 |
| Mozilla Firefox | Version 23 | Version 27 |
| Apple Safari | Version 7 | Version 7 |
Most browsers will allow the use of any SSL or TLS protocol. However, credit unions and banks should use TLS 1.1 or 1.2 to ensure a protected connection. The later versions of TLS will protect encrypted codes against attacks, and keep your confidential information safe.
Transport Layer Security (TLS) is the successor protocol to SSL. TLS is an improved version of SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information. The two terms are often used interchangeably in the industry although SSL is still widely used.
- Open the Tools menu (select the cog near the top-right of Internet Explorer 10), then choose Internet options:
- Select the Advanced tab.
- Scroll down to the Security section at the bottom of the Settings list.
- Select Use TLS 1.1 and Use TLS 1.2.
- For extra security, deselect Use SSL 3.0.
Is TLS 1.2 Vulnerable?
Bad news: there's a vulnerability in TLS 1.2. Good news: researchers say it's “very hard to exploit” and major vendors have already released security patches for it.
TLS 1.2 is more secure than the previous cryptographic protocols such as SSL 2.0, SSL 3.0, TLS 1.0, and TLS 1.1. Essentially, TLS 1.2 keeps data being transferred across the network more secure.

Almost every single article under the sun tells me to check the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\ and check the keys within it.
