When was the last time you got paid $40,000 for a few days of work? That is what happened last year to Russian independent security researcher Andrey Leonov, who discovered that if you upload a specially constructed image file to Facebook, you can make Facebook's internal servers, nested deep within their firewalls, run arbitrary commands to expose sensitive internal files in a way that could easily lead to a data breach.
Controlling who can access your images and videos, and when, can be an important concern for your business and security workflow. You may have resources that you only want some of your users or employees to access, or you may need to make sure that your original resources are secure, and only transformed (edited) versions of your resources are delivered, e.g., with a watermark or logo displayed.
Even though websites have changed dramatically over the years – from simple text-based pages to advanced in-browser apps full of images and videos – the underlying HTTP protocol really hasn’t changed - until recently, with the approval of the HTTP/2 protocol by the IETF. Today Cloudinary is proud to announce, as part of a CDN infrastructure upgrade, general availability of HTTP/2 support in our image and video management solution. This will help you optimize the user experience on your app or website even more.
Are you delivering your site via HTTPS or considering it? You're not alone - in 2015 the number of sites running on HTTPS almost doubled. Both consumers and web developers are now much more aware of the value of the humble green lock displayed in the address bar. The benefits of using HTTPS extend beyond the customer’s safety, to SEO boosts, and advanced functionalities that are only available when delivering via HTTPS, such as HTTP/2 and WebRTC.
Modern web sites and mobile applications frequently showcase a rich set of images with various sizes and dimensions. Such services can even have their graphics, image resolutions and overall look & feel vary between different devices (desktop, mobile, etc.), and may change dramatically with constant upgrades.
