What is the difference between Cyber Security and Digital Security? They sound very similar (same) to me, But I have read that

current techniques of Machine Learning can provide Digital Security, But not Cyber Security.

So what is the difference?

    Could you give us the source of the quote? – S.L. Barth - Reinstate Monica Jul 18 '16 at 13:56

    Its simply slides of a course at university. Maybe it is relevant that in another bullet point, it says "in 86% cases of breaches in Verizon, evidence was in logs". Maybe it suggests that digital security is available because samples are accessible. But somehow this is not the case for cyber security. Its as brief as that. – Makan Tayebi Jul 18 '16 at 14:01

    Since "cyber" pretty much means exactly the same thing as "digital", you might want to ask whoever came up with these bull** terms to actually define them and their respective definitions. – AviD Jul 18 '16 at 14:12

    No idea what the difference would be. From just reading the short quite, they could be synonyms - ML can target X, but can not provide X. – Anders Jul 18 '16 at 14:45
  • That's my bad. didn't articulate it well. The actual verb has been "do". ML can not do Cyber Security. which I changed. will correct. So far the Question is not looking good. I will clarify whatever was meant by the lecturer. – Makan Tayebi Jul 18 '16 at 14:49

"Cyber" is a very frequently misused buzzword people like to throw around because it sounds futuristic and cool. What many people mean when they use the word is "computer-related".

What it actually means is the short form of Cybernetic: The integration of human and technology.

What the quote could mean (you are not providing context) is that machine learning can help for security problems in machine-machine interaction (digital) but not human-machine interaction (cybernetic). For example, you can already use machine learning to teach a program to automatically detect an automated brute force attack on a login form, but you can't yet teach it to automatically detect a phishing attempt. (I am not claiming this is right or wrong, just that it might be what the author wants to say)

Generally speaking Digital Security is limited to only data or bit-type assets. Cyber Security on the other hand has a full ten domains (http://library.ahima.org/doc?oid=107038#.V4zmjNIrLIU) and includes things like operational, physical or business security. This can include things under the "security" structure that have nothing at all to do with Digital Security, such as insurance.
