Web Browser Security Issues
This section describes security issues with web browsers.
Web browsers and web servers often need to update their security requirements and configurations to ensure secure communication. Sometimes when web browser security requirements change, the browser is no longer able to connect to the Control System or other web interfaces.
The following fixes are available to resolve browser connection issues caused by changes in browser security requirements, or by an organization's need to maintain legacy (insecure) protocols:
| Issue | Affects MapR Version |
|---|---|
| Weak Ephemeral Diffie-Hellman Key | 3.x, 4.x, and 5.0 |
| Unable to Establish a Secure Connection | 3.1.x, 4.0.x |
| Requirement to Enable Insecure Protocols (Not Recommended) | 5.1 |
NOTE
Based on your MapR version, you may need to apply the fix for more than one issue.
