Disable RC4/DES/3DES cipher suites in Windows using registry, GPO, or local security settings.
- You can do this using GPO or Local security policy under Computer configuration -> Administrative Templates -> Network -> SSL Configuration Settings -> SSL Cipher Suite Order.
- Set this policy to enable. Each cipher suite should be separated with a comma. Remove as needed based on the list below.
- To disable based on registry, reference this article:
