Creating Secure Code

First Principle of Code Protection: Code Isolation and Confinement

In today’s Internet-driven world, we often find ourselves running untrusted code on our devices. This code is contained in programs, applications, extensions, plug-ins, and codecs for media players, which we have become accustomed to naively trusting and downloading. However, malware creators take advantage of unknowing users who download or use infected code. Such infected code can be directed toward a variety of devices including our computers, tablets, and smartphones. Hackers may hide their malware code in any component where they see an opportunity to catch unaware users. Specialized codecs for media are examples of components that are frequently ...

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
