TLS_FALLBACK_CSV

The TLS_FALLBACK_SCSV vulnerability addresses a specific issue in SSL/TLS protocols where a client and server could be forced to use a less secure version of the protocol through a downgrade attack. This security mechanism prevents such attacks by allowing the client to indicate that it is attempting a fallback connection. If the server detects this in a scenario where a higher protocol version is supported, it will reject the connection, thwarting attempts to downgrade the security of the communication.

How to fix "TLS_FALLBACK_CSV" vulnerability?

1. Enable TLS_FALLBACK_SCSV on the Server:

2. Disable Older SSL/TLS Protocols: As part of a comprehensive approach, disable older, less secure protocols like SSL 3.0, TLS 1.0, and TLS 1.1 on your server. Focus on supporting TLS 1.2 and higher, which are more secure and less prone to certain types of downgrade attacks.
