Security by obscurity is underrated
Agree with the article.People have been misinterpreting "security by obscurity is bad" to mean any obscurity and obfuscation is bad. Instead it was originally meant as "if your only security is obscurity, it's bad".Many serious real-world scenarios do use obscurity as an additional layer. If only because sometimes, you know that a dedicated attacker will be able to breach, what you are looking for is to delay them as much as possible, and make a successful attack take enough time that it's not relevant anymore when it's broken.
