(Note that we recorded this podcast back in July 2012. You can also listen directly on Soundcloud. This raises the question: if snooping and falsifying web traffic is so easy when plain old HTTP is used, why do we still have HTTP at all?Ĭlick-and-drag above to skip to any point in the podcast. Those eavesdroppers could be nosy neighbours who have figured out your Wi-Fi password, other users in the coffee shop you’re visiting, curious colleagues on your work LAN, your ISP, cybercriminals, or even your government. Without HTTPS, there are many places along the way between your browser and the other end where not-so-innocent third parties could easily eavesdrop on (and falsify) your web browsing. This stops attackers sneakily altering or corrupting data in transit, such as replacing bank account numbers, changing payment amounts or modifying contract details. HTTPS traffic isn’t just encrypted, it’s also subjected to an integrity test. The content of the traffic can’t easily be modified on the way out or back.This makes it much harder (nearly, if not absolutely, impossible) for attackers to eavesdrop on secrets such as passwords, credit card numbers, documents, private photos and other personal files that show up in your network traffic. The content of your web request and the reply that comes back can’t easily be monitored by other people on the network.HTTPS, as you probably know, stands for secure HTTP, and it’s a cryptographic process – a cybersecurity dance, if you like – that your browser performs with a web server when it connects, improving privacy and security by agreeing to encrypt the data that goes back and forth.Įncrypting HTTP traffic end-to-end between your browser and the server means that:
