To help browse the web safely, browser including Chrome indicates connection security with an icon in the address bar on HTTPS conncection type.
Until now, there was no indication when a conncection is made over HTTP, but that's going to change now, as Google has come up with a feature in Chrome to indicate a "non-secure" icon over HTTP connections.
In following releases, "we will continue to extend HTTP warnings, for example, by labelling HTTP pages as "not secure" in Incognito mode," stated Google adding, "where users may have higher expectations of privacy. "
Eventually, Google plan to change HTTP security indicator to a red triangle currently used for broken HTTPS.
Problem with HTTP connection is, "when you load a website someone on the network can easily look at or modify the site before it gets to you."
In a post, the team said, that starting January 2017, [Chrome 56] will begin marking HTTP sites that "transmit passwords or credit cards as non-secure," and as part of a long-term plan it will "mark all HTTP sites as non-secure."
Chrome currently indicates HTTP connections with a neutral indicator.
Furthermore, the team notes they've acheived a milestone with more than half of Chrome desktop pages and top 100 websites [since February, 12] now serving over HTTPS.
HTTPS is easier and cheaper than ever before, and offer both "best performance" and "powerful features that are too sensitive for HTTP."
The company wants to label HTTP sites more clearly /accurately as non-secure in gradual steps, and based on increasingly stringent criteria.
