Google has rolled out new security features for users of Gmail and Drive, as well as its Chrome web browser. For Gmail and Drive users, Google is offering an opt-in feature called the Advanced Protection Program, aimed at those who are more prone to online threats because of the nature of their work. The company announced the program in a blog post on Tuesday.

Denunciations like "most frequently exploited product" have been common for the software.

The report comes as White House cybersecurity czar Rob Joyce says he is reviewing the Vulnerability Equities Process — the policy structure that decides whether zero days found by U.S. agencies should be disclosed to the manufacturer.

A blog post by the maker of the Firefox browser says Chrome engineers are correct in their assessment of the problems with Symantec-issued internet security certificates — but they may have gone too far by proposing to distrust them.

Two of the biggest names on the internet embarked on a game of chicken this week over the little green padlock in the address bar.
