Deliberate practice in information security
Deliberate practice is the act of performing a set of tasks that are just slightly more difficult than what you’re used to, so you can get better at a specific activity and move from a novice to an experienced practitioner. In this post, Security Engineer Sandra Escandor-O’Keefe walks us through the art of deliberate practice, offering tips for novices and mentors alike.

Optimizing HTTP/2 server push with Fastly
Since we made HTTP/2 generally available in November 2016, h2 traffic has been steadily growing as more customers migrate to the new version of the protocol; since the beginning of 2017, h2 traffic has increased by over 400% and h2 requests now make up more than 25% of the total requests on Fastly’s network. HTTP/2 has numerous practical implications, but in this post we’ll focus on server push, which can save on round trip request time. Here’s how you can get the most out of server push with Fastly.
How to bootstrap self-service continuous fuzzing
OSS-Fuzz is an innovative project that is both advancing the state of the art in OSS security engineering and immediately improving the overall quality of the software that serves the internet.

The IoT industry’s response to emerging threats
Late last year, we took a look at how the Internet of Things (IoT) is under attack. We analyzed hundreds of individual IoT devices to see how often they were probed for vulnerabilities, with the intention of being employed for IoT botnet attacks. We did more robust vulnerability research on IoT devices that have been found vulnerable in the past and concluded that while malicious probes are constant, manufacturers have taken action to update their firmware and address security holes. Read on to hear our latest findings.
