TLS Downgrade Attack

What is the TLS Downgrade attack?

Modern TLS clients and servers support older versions of TLS protocol and weaker cryptographic algorithms for backward compatibility. TLS downgrade attack is an attack in which an attacker tricks a TLS client and the server to use an older version of the TLS protocol or weaker cryptographic algorithms or insecure parameters. As a result, the attacker can exploit the security vulnerabilities of the older protocol version or weak cryptographic algorithm, or weaker parameters to intercept the connection and steal sensitive data.

How does TLS downgrade attack work, and how can we prevent it? In this article, we would discuss that in detail.


In this article, we will discuss:

  • What is the TLS Downgrade attack?

  • How does the TLS Downgrade Attack work?

  • How to prevent the TLS Downgrade Attack?
