Google (hereinafter referred to as Google) provide Gmail service, upgraded security services. Google said in a blog post published today, Gmail will increase warning way, to help users send and receive e-mail for better self-protection measures. One of the biggest changes is the expansion of the "safe browsing" the scope of the notice, when a user receives a email with suspicious links, alerted not only in the preview. When clicked, the system will send a reminder before loading it in the link is still to determine whether the user wants to open the links .

Google in February this year, had begun to mark the unencrypted e-mail, alert Gmail users to set TLS encryption. If there is no in-transit encryption, email may be obtained by an attacker because the e-mail body and read data is sent in plain text. Google said that since after the alert, an increase in the number of emails sent using an encrypted connection 25%. This upgrade also from other email providers to deal with Google, update their technology and services, send e-mail to yourself to avoid waste and disturbed by the Google message flags.

In addition, Google also continues to struggle with the Government-backed attacks. Apple isn′t the only company with United States government spies battling the Silicon Valley technology companies. Google′s system to detect when there is a Government-sponsored hacking Gmail users being monitored, will display a full screen warning message . Google said in its official blog, 0.1% not only Gmail users will receive a warning, and this warning is usually cross-journalists, members of Parliament and the nation and party activists. But this warning is clearly very important, you can troubleshoot their mailbox is being monitored.

Google（以下简称谷歌）提供的Gmail服务，升级了安全服务。谷歌在今天发布的一篇博客文章中表示，Gmail里将增加警告的方式，以此帮助用户在收发电子邮件时更好地采取自我保护措施。其中一项最大变化是扩大了"安全浏览”通知的范围，当用户收到的电子邮件有可疑链接，不仅在预览时发出提醒。当点击后，系统会在该链接加载前仍旧发出提醒信息，确定用户是否想打开该链接。

谷歌在今年2月，已经开始对未加密电子邮件进行标记，提醒Gmail用户设置TLS加密。如果没有在途加密，电子邮件可能被攻击者获得，因为电子邮件身体和数据以纯文本发送读取。谷歌表示，自从发出提醒后，使用加密连接发送的电子邮件数量增加了25%。这种提升也来自于其他电子邮件服务商为了应付谷歌，更新了自己的技术和服务，使自己发送的电子邮件避免得到谷歌的垃圾和不安邮件标记。

除此之外，谷歌也继续与政府支持的攻击行为展开斗争。苹果并不是唯一一家与美国政府的间谍攻击做斗争的硅谷科技公司。当谷歌系统发现有政府支持的黑客正在监控Gmail用户时，会展示一条全屏警告信息。谷歌在官方博客中表示，只有不到0.1%的Gmail用户会收到这种警告，而这一警告信息的对象通常是跨国记者、议员和民族和党派激进人士。但这种警告显然非常重要，可以排查自己邮箱是否被监听。
