Validation section fix

[gsmcnamara-okta]

From the Validation section, is this part backwards?

Anytime data is passed from a trusted source to a less-trusted source,...

[PauloASilva]

You're right it would make more sense the other way around.

We can also consider rephrasing it a bit to something like "Anytime data is exchanged between two parties or systems, integrity checks can be made in order to guarantee that the data has not been tampered with and the receiving party/system receives exactly what the other party/system sent.

What do you think @gsmcnamara-okta? Would you like to open a Pull Request?
