It seems that HTTPS is becoming more imperative to use than ever before. At this point and time most, if not, all websites should already have it implemented as the standard. I think that is not the case though.
There are websites out there that are still running on HTTP, or parts of it. What I mean by that is some websites are HTTPS, but then redirect you to an insecure HTTP page. It is quite scary especially if any sensitive information can be sent over HTTP on accident.
Without HTTPS, websites are vulnerable to traffic snooping. Routers on the internet or any specialized equipment installed can sniff out the contents of a non-encrypted HTTP packet and record it. This makes your login information 100% vulnerable to theft by hackers who use these tools for malicious purposes.
Also files downloaded through HTTP can be intercepted and compromised easily. This goes especially for proxy servers that cache files. A bad copy of a particular executable or image can be cached and downloaded into your machine. This is why most downloads nowadays include hash checks to make sure the file is from the original source.
It is always important that in your web browser, you should always look right next to your address bar. A lock indicates that HTTPS is present on the web page and the contents are encrypted. Also make sure that https:// is also present which can help you determine the safety of any information being sent.
Luckily some web browsers are starting to enforce websites to use HTTPS. I do know for a face that Google Chrome has already implemented this not too long ago for downloading. If you want to force HTTPS then luckily there’s an extension for that.
HTTPS everywhere is a browser extension that attempts to force websites to redirect to HTTPS. You can visit the following link and download it for your preferred browser here. Unfortunately sites that don’t support HTTPS at all won’t work. At that point, asking the webmaster to implement it would be a good start.
I hope that you will find this useful in ensuring that your browsing experience will always be safe!
