It’s Time To Think Seriously About Retiring TLS Certificates Using SHA-1 Hashes

Time To Retire SHA-1SSL / TLS certificates and the certificate authorities that sign them are vital to online security. They’re responsible for two important aspects of secure online communication: encrypting network traffic and verifying the identity of sites. Any SSL / TLS certificate can be used to encrypt data, but only certificates signed by a certificate authority can be used to verify the identity of a site. If the identity verification system stopped working, there would be no way to stop a malicious site from pretending to be your bank, Google, or any other site. Read more »

Legacy Complexity Gets In Way Of CloudWhen I talk to companies with established legacy infrastructure on which their business depends, I often hear something like the following: “In theory, we’d love to use the cloud, but it’s way too complex and risky to move.” Their current infrastructure and the applications it supports are working now — however unsatisfactorily — and making the move would throw a cat among the pigeons, leading to potential operational disruption.

Why You Should Consider A Microservice Architecture For Your Next Cloud-Based Web Application

Consider A Microservice ArchitectureBack in the day, most applications were conceived and developed as monoliths. All of the application’s functionality was part of a single, inseparable unit. Many web applications are still developed in this way, especially in the enterprise, but, aided by cloud technology, some companies are embracing the benefits of a microservice architecture — with Netflix being a leading example.

A microservice architecture consists of multiple small, discrete units of functionality that communicate with each other via simple APIs. Microservice architectures have some unique benefits — and some unique drawbacks — when compared to monolithic design paradigms. Read more »

With ever increasing frequency, we hear of major security breaches at organizations users should be able to trust with their data. As more of the economy moves online, the potential rewards for hackers have increased exponentially. Developers feel beleaguered. In a reversal of the usual commonplace about criminals and those who fight them, hackers have the luxury of making as many mistakes as they need to before they hit on the right strategy.

For several hours the link leading to one or more of the distribution’s direct downloads in fact lead to a compromised version of the distro with a backdoor installed.

Is Your Website Obese? Here’s What You Can Do To Fix It

Is Your Website ObeseIt’s almost a little jarring, if you stop to think about it. Only two decades ago, the average size of a web page was 14.1 kilobytes. Anything larger was generally considered overdoing it.

As network technology improved and the Internet ingrained itself more and more into our lives, however, that number exploded – today, the average page hovers somewhere around 2 or 3 MB, and there’s no indication that this growth trend is going to stop anytime soon. Read more »
