Is the Internet as safe as we think?

Today, Internet users are at greater risk than ever. Along with our evolving technology and the evolving Internet society and culture, we are increasingly relying on this concept not only for exploitation but also for criminal purposes. When discussing all aspects of Internet security, there are many areas to study. As an ordinary IT user, and in my fluent field, I have a very strong opinion on which Internet security field I think I am worried.

When we post to the Internet, I think that we are safe and secure in our living room and office. It does not matter whether you are wearing underwear or wearing an appropriate suit. why? This is because we are not actually in a safe and private place, but actually in a very crowded room surrounded by hundreds of people. People do not have to listen to your conversation or listen. Listen to conversations and reply to other tweets by posting wall information and general tweets to people not on the circle list (ie, Facebook friends list, Twitter fans list, etc.) You can do it. If you are talking to your spouse at dinner at a restaurant, if you do not pay attention to the tables around you, you will still hear it even if you are not particularly concerned with your conversation You can do. What are you saying correctly?

Browsing web pages on a wired network behind a firewall or VPN is considered a secure way to access the web. But when we come online, most of us will not be that long. Instead, we like to surf on wireless networks. Given that everything worked well, think about whether the hotel or cafe coffee shop where we live will spend time introducing a secure wireless network to our customers.

When connecting to an untrusted network (such as public WiFi, WiFi from a store or hotel), we all want to access the Internet securely and safely from my device. A virtual private network (VPN) is a network that establishes a secure network connection on a public network such as a private network owned by the Internet or a service provider, and can transfer an untrusted network to itself and securely Technology. Your own server seems to be on a secure private network. Group nogroup By default, OpenVPN runs as the root user, so there is full root access to the system. Restrict OpenVPN to user nobody and group nogroup. This is an unprivileged user who does not have default login capabilities. It is usually reserved for running untrusted applications, such as web-connected servers.
