After getting incredible reviews on my original post 'Security on the Internet,' I decided that it would be a good idea to bring you, my readers, a second part to that post. So here it is! Today I would like to cover a few topics including PIN codes, links and email.
To begin with I would like to give you a few quick tips on creating a secure PIN code. As most PIN codes are four digits, that is what I will be teaching you today. The first point to remember about PIN codes is to not make them simple. This is to say that you shouldn't use your birthday or your anniversary as a code. But if those numbers aren't secure, what is? I personally recommend randomising digits with dice or online software, ensuring that no one could simply make an educated guess as to your PIN code. Never use dates or the last digits of your phone number. By randomising you create a code as secure as is possible for four digits.
The next thing I would like to talk about is links. Have you ever been in an IRC, or chat room with a stranger who suddenly sends you a link saying that you'll get something if you click it? This is commonly done with free music, movies and porn. People send these links that yes, may lead you to a free gift, but can also lead you to something else, like a download for a virus or a phishing page. I would caution against opening any links sent to you by strangers online, as they can be dangerous for you and your device.
A few seconds ago I mentioned phishing. Don't know what it is? Or do you think you'll get a tasty meal out of it? Phishing is actually a technique where hackers create a fake webpage, identical to the original, and use it to steal your passwords. When you sign in on a phishing page, assuming it is legitimate, your passwords are stored in a document for the hacker to recover and use later.
The final topic I would like to cover is email. For some time now I have been looking around for a secure email server, one where my passwords and private information will not be hacked or stolen. Google and Outlook are simple and convenient, but they are also not secure. They are quite easily hacked with phishing techniques or have their passwords easily leaked by those with access. In my search I have found only one email server that I fully trust. It is a company called ProtonMail. Based in Switzerland, ProtonMail is a zero-access server, meaning the company has no access to your passwords or emails. This protects you from information leaks and NSA snooping, which is great, but what about the phishing techniques I mentioned earlier? These are stopped by nice, dual-password feature that ProtonMail uses to lock out hackers. After analyzing at their source code and working with their software for some time, I have decided that ProtonMail is as secure as it gets.
