Right. Security isn’t a feature you add on. It’s a mindset that has to influence every line of code you ever write. Just like ethics, reliability and performance. We, as software developers, are building the world we will inhabit. Make it a good one.
Not wrong, but also a counsel of perfection. “Write better code.” But how? You’re right that security can’t be reviewed-in after the fact; it must be written securely in the first place. It follows that all devs (not just “security engineers”) need to learn more about security.
