Artificial intelligence vs machine learning vs deep learning – what's the difference?

A recent Sophos study found that almost half (48 per cent) of Australian businesses were hit by ransomware attacks last year, highlighting the need for security vendors to continuously innovate, and more importantly, stay ahead of the cybercriminals. As such, innovative technologies such as artificial intelligence (AI) have become imperative to cybersecurity. There is a misconception that these technologies are the same and can be used interchangeably; while they leverage the same AI principles, machine learning and deep learning are fundamentally different. So what is the difference and how does it work in relation to cyber security? AI is now a widely understood technology, mostly it has been made famous by Hollywood movies (although its application in security does not involve a robot attacking a hacker).
