Insecure Transportation Security Protocol Supported (TLS 1.0)
Invicti detected that insecure transportation security protocol (TLS 1.0) is supported by your web server.
TLS 1.0 has several flaws. An attacker can cause connection failures and they can trigger the use of TLS 1.0 to exploit vulnerabilities like BEAST (Browser Exploit Against SSL/TLS).
Websites using TLS 1.0 are considered non-compliant by PCI since 30 June 2018.
We recommended to disable TLS 1.0 and replace it with TLS 1.2 or higher. See Remedy section for more details.
Configure your web server to disallow using weak ciphers. You need to restart the web server to enable changes.
- For Apache, adjust the SSLProtocol directive provided by the mod_ssl module. This directive can be set either at the server level or in a virtual host configuration.
- For Nginx, locate any use of the directive ssl_protocols in the
nginx.conffile and remove
- For Microsoft IIS, you should make some changes on the system registry. Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on your computer.
- Click on Start and then Run, type
regedit, and then click OK.
- In Registry Editor, locate the following registry key or create if it does not exist:
- Locate a key named
Serveror create if it doesn't exist.
- Under the
Serverkey, locate a DWORD value named
Enabledor create if it doesn't exist and set its value to "0".
