In the US, security breaches have continued to raise concerns about the protection of personal data. In September, Facebook experienced the largest breach in its company history, with the personal information of nearly 50 million users hacked. That's led the company to re-think how it safeguards data. Mark Niu has the details from San Francisco.

As data breaches continue to pile up for U.S. retailers and tech companies like Facebook, even the generation that grew up using social media is putting the brakes on what they post.

"I'm very cautious about what I put on social media, I don't like? I don't reveal too much information."

"We also should not be putting so much trust into these websites and stuff."

Software developer James Hay advises against publishing information you're uncomfortable sharing.

JAMES HAY SOFTWARE DEVELOPER "That's the best way to keep hold of your information, just don't let it out to the public. Then, if it's a matter of a small startup that's gathering information online or if it's a mega-giant like Facebook - for business or your personal use of consumption, the same rules apply. You don't want to share anything you are not comfortable."

MARK NIU SAN FRANCISCO "The lines between personal and business data are also starting to blur. Facebook has been offering companies 'Workplace by Facebook' -- a work version of their social network for company employees to communicate and share information with each other."

On Sept. 28th, the day of the massive security breach, Workplace by Facebook customer, Walmart, reportedly contacted Facebook for assurances that their business data resided outside the consumer version of Facebook.

Facebook said yes, and even revealed it already had plans to move Workplace by Facebook to a separate domain that didn't even included the Facebook name.

RAY WANG PRINCIPAL ANALYST CONSTELLATION RESEARCH "A lot of concern about all the breaches that have been happening at Facebook. What people don't realize is that Facebook for work has been growing. There are 30,000 companies, there are hundreds of millions of users. The problem is what's the security like? Corporate IT folks and security folks are extremely worried about mingling those instances inside the Facebook environment. So, they've got a brand new environment, new data centers and a new name called Workplace.com."

Wang says it's a trend has been happening for some time.

He notes that Amazon created a separate setup for Amazon AWS Cloud services, and Alibaba has successfully separated its enterprise cloud services from consumers services, too.

RAY WANG PRINCIPAL ANALYST CONSTELLATION RESEARCH "We're seeing this separation occur because there are different needs. Consumer-grade is very different from enterprise-grade, especially when you have companies with trade secrets, lots of intellectual property and commentary they'd probably never want leaked out."

But that raises a question: doesn't the personal data deserve the same level of protection as businesses?

RAY WANG PRINCIPAL ANALYST CONSTELLATION RESEARCH "Enterprise and consumer security should be at the same level. At this point today, it isn't. That's one of the reasons there's a separation. Maybe there's a lot that's going to be learned at Workplace that filters over to the regular Facebook."

But in the end, businesses pay, while consumers get Facebook free. The tradeoff is access to your personal data. It's a commodity-sold to advertisers who want to use that information to sell you something. Mark Niu, CGTN, San Francisco.
