F5 “SSL Everywhere” architecture is centered on the custom-written SSL/TLS stack that is part of every F5 BIG-IP deployment. This enables F5 to have the visibility and control over SSL/TLS traffic in the era of HTTP/2.0.
Why is the visibility and control of SSL/TLS traffic so important? Only a decade ago, SSL was reserved for financial institutions and some specific organizations like public sector agencies for the log-in pages of security-conscious web sites and services. Today this has been expanded to most web-based services, and is quickly becoming the de-facto protocol for communications. Based on industry research from Gartner, more than 50 percent of the world’s Internet traffic will be encrypted by the end of 2015.
TLS today offers a paradigm shift in which companies approach IT networks, as it offers communications security over a network server. The connection between client and server is private because symmetric cryptography is used to encrypt the data transmitted.
Visibility and control over SSL/TLS traffic in HTTP/2.0
With the growing use of encrypted traffic, the traditional approach of depending on firewalls, intrusion protection systems and intrusion detection systems has become obsolete, as these devices will be blindsided without knowing the data stream that is passing through it.
