History SEP 2012 At ekoparty 2012, Thai Duong and Juliano Rizzo announced CRIME, a compression side-channel attack against HTTPS. An attacker with the ability to: Inject partial chosen plaintext into a victim's requests Measure the size of encrypted trafficcan leverage information leaked by compression to recover targeted parts of the plaintext. Compression side-channel attacks are not new. Indeed, ten years before Duong and Rizzo's presentation, a paper appeared describing such attacks in general. However, CRIME gave a concrete, real-world example. The particular demonstration given at ekoparty showed how an attacker might execute this attack to recover the headers of an HTTP request. Since HTTP headers contain cookies, and cookies are the primary vehicle for web application authentication (after login), this presents a significant attack. By disabling TLS/SSL-level compression – which was already little-used, and in fact disabled in most browsers – the attack as demonstrated at ekoparty is completely mitigated. Breach While CRIME was mitigated by disabling TLS/SPDY compression (and by modifying gzip to allow for explicit separation of compression contexts in SPDY), BREACH attacks HTTP responses. These are compressed using the common HTTP compression, which is much more common than TLS-level compression. This allows essentially the same attack demonstrated by Duong and Rizzo, but without relying on TLS-level compression (as they anticipated). BREACH is a category of vulnerabilities and not a specific instance affecting a specific piece of software. To be vulnerable, a web application must: Be served from a server that uses HTTP-level compression Reflect user-input in HTTP

But eliminates the option of humans being able to read the information without having a tool to translate it. The latter could be a disadvantage for system analysts who are accustomed to going through processes line by line for troubleshooting.What Is the HTTP/2 Adoption Plan?Major browsers, such as Chrome and Firefox, already include HTTP/2 support in their latest versions. Google will be phasing out its SPDY project by early 2016. It’s unknown how this will impact sites still using HTTP, but Google is allowing the extra time so developers can either move to the new protocol or, if they aren’t ready to upgrade to HTTP/2, revert to HTTP/1.1 to avoid the problems they might experience with SPDY (as they do to meet the needs of other browser types).Web servers, however, generally have longer update cycles and will therefore take longer to implement HTTP/2. Apache and Nginx currently support HTTP/2, while others are in the process of adopting the new protocol.How Should Developers Prepare?HTTP/2 requires developers to unlearn a lot of tricks they employed to overcome the limitations of HTTP. Design hacks developed to make HTTP run faster, such as CSS sprites and inlining, can create issues when used with HTTP/2.In addition, since HTTP/2 is binary, some network inspection/management techniques and tools that you’ve relied on in the past will no longer be useful. For example, plain-text debugging is no longer an option. Therefore monitoring tools will need upgrading as soon as HTTP/2-friendly updates are rolled out.Web server frameworks will also

Bloat and make sure that your users have a better experience? Note: dynamic content can also be cached by using a CDN cache instead of the original, probably distant server, thus reducing the time it takes to load. Caching, therefore, increases the loading speed of websites and according to Google, “no matter what, faster is better and less is more”.Note: Using caching plugins is not the only method to increase your websites speed, and should be done in concurrence with other methods which are listed in these great articles: How to Speed up Your WordPress Website — Part 1 and How to Speed up Your WordPress Website — Part 2Now that we’ve established that you need caching plugins for better loading speed, let’s understand why you need better loading speed times.Image Optimization for Speed and PerformanceWhile caching plugins significantly improve site speed, pairing them with image optimization can boost performance even further. Using an image optimizer plugin reduces file sizes without sacrificing image quality, helping your site load faster and reducing server load. This is especially useful for image-heavy websites, as optimized images not only improve user experience but also complement caching for a more efficient, faster website. How Does Loading Time Affect Your Site? There are a number of reasons why having better loading speeds is good for your website. SEO Loading times affect your SEO. According to Yoast SEO: Site speed is a ranking factorFast sites are easier to crawlFast loading sites have higher conversion ratesIt reduces bounce ratesIt improves general user experience (less stress!)Faster websites, therefore, get a favorable rank with search engines. Certainly, it’s not the only factor that does, but if we were to compare two websites, with all the information and other factors being the same, the website that loaded faster would get a better rank. Furthermore, Google has confirmed that it takes page speed into consideration. User Experience Better loading speeds affect the user experience, and not only that, but slow loading times will have a negative effect on the brand’s reputation. Bounce Rates Bounce rates represent the percentage of visitors who enter a website and then leave before viewing other pages on the website. According to Google: Up to 3 seconds of load time increase the bounce rate probability by 32%Up to 5 seconds of load time increase the bounce rate probability by 90%Up to 6 seconds of seconds load time increase the bounce rate probability by 106%Up to 10 seconds of seconds load time increase the bounce rate probability by 123%This indicates that the longer it takes for the website to load the first time, the less likely it is that the user will stay to look at other pages on
