Simple answer – yes.
You need to know more about what is going on, what an organisation does, why it does it to understand how IG applies.
If you could run a business without knowing anything about anyone you would have little or no issues but businesses (and life) is not like that.
The issues that are being faced by businesses are increasingly complex because life is increasingly complex and the impact of new technology impacts as well.
If you post a letter in theory you know that you have written one, put a stamp on it, put it in the post box, someone collects the post and then takes it to the Royal Mail Office and so on.
An email is not like that and has to be deconstructed and processed across multiple servers to get to the recipient so what happens when that goes wrong?
So the simple answer is Yes – IG is getting harder.
