Very far from it. The cloud is the source of some of the largest hacks ever.
I did a paper a few years ago about a company named Epsilon that was a cloud-based service providers for grocery stores. When customers sign up for discounts with companies like Walgreens and Safeway, the stores send the information to Epsilon and Epsilon then handles that e-mailing of store flyers to the customers. TENS OF MILLIONS OF CUSTOMERS.
Epsilon was hacked ten years ago and something like 75 million e-mail addresses and associated customer information was taken. It wasn't the world's most sensitive information, but it was far worse than just a compromise of e-mail information. The fact is, when a hacker has your e-mail address, your name AND a business where you do business, he can then launch an extremely believable phishing attack against you. For instance, he can send you something coming from your local grocery store naming you and stating that your prescription is ready to be picked up and "Click HERE for details."
So, that was about 75 million e-mail addresses and names compromised in a single attack. Probably at least three of the folks reading this post were affected. And I bet you never even knew.
That's the cloud: Insecure and very tempting to hackers due to the amount of the information that can be taken. I don't trust it a bit.
