This seems to be useful for overseas employees!I wonder if iOS will respond by default ...
ALPHABET, Google's holding company, has released a new tool to protect user communication from the national Internet censorship.
Jigsaw (jigsaw), a subsidiary of Alphabet, released an Android app called "Intra".It is a tool that protects users from monitoring and operating DNS communication by state and ISP.
What is the monitoring and operation of DNS communication?For example, in Iran, the government is monitoring access to specific websites, preventing users from going to sites that they do not want to see religious and politically.The same is true for Chinese gold shields (also called Kinjun, Great Firewall), and is held in multiple countries, including Pakistan.
For example, if a user tries to access the domain Domain-gizmodo.com, the DNS server usually will refer to the IP address corresponding to that domain.In the case of China, a gold shield has a domain blacklist and trying to query a domain in it, tells user browsers instead of the correct IP address and guides them to another site.I will do it.
"Intra" prevents DNS monitoring and operations from third parties by encrypted communications in which IP addresses are referred to this DNS server.By default, it is set to use Google DNS servers, but you can also use another server.The DNS server needs to support the encryption technology called DOH, but it also supports the DNS server of CloudFlare, which has become a hot topic when the IP address inquiry is fast.It's two birds with one stone.
DNS eavesdropping and tampering is a solid hacking method that can be used not only for censorship by state and ISP, but also for attacking general users by malicious hackers.Not only is your privacy at risk, but you are guided to a fake site similar to the real thing and pulled out your password.
According to CNET, the Android 9 -Pie update can enable DNS encryption by default (I want to use Android).However, this app seems to have been released because about 80%of Android users do not use the latest OS.Users who use old Android OS are apps that you definitely want to use to protect yourself.
