Emails
can be a tricky thing. Even though they are one of the most important
tools in everyday life, they can often pose security problems for users.
To protect users, Google has released two new security features that
attempt to make Gmail a little more foolproof place to be. The new
features will rollout within a couple of weeks, Google says.
On
the Web and on the Android app, users will get see now red question
marks instead of profile pictures of senders if they have not been
authenticated by either Sender Policy Framework (SPF) or DKIM, the search giant said in
its blog
post.
For the Web only, Google is extending its Safe Browsing feature
from Google Search and Chrome to Gmail. When you receive an email with a
link to website known to be associated with phishing, malware, or
unwanted software, users will now see the below warning.

It is
important to mention that a sender who has not been authenticated or the
link that has been shown as potentially dangerous might or might not
pose any threat to the user. These warning signs have been added so that
the users can take a moment to consider their safety before they fall
prey to the hackers.
Earlier this year, Google added
a new security feature to Gmail - an upgrade to its Data Loss
Prevention service with the inclusion of OCR. The feature reads email
attachments with the aim of preventing a leak of confidential documents,
and is meant only for Google Apps for Work Unlimited customers.
Before
that, Google
started
warning Gmail users about emails from unencrypted sources, flagging
those email providers not using the Transport Layer Security (TLS)
standard.
