I see the contradiction there!

The bit about the "aims of the module" comes from its aims to get people thinking in a certain way about security, something I definitely already had. But that doesn't mean it had nothing to teach me - it was quite a while ago that I took it, but one exercise about the nuances of the setuid bit and how misconfigurations could be exploited stands out as something I doubt I'd have come across otherwise. There was also plenty of content on cryptography and basic binary reverse engineering/attacks that I'd not seen before.

My level of ability and knowledge isn't consistent - some places I'd dug into more, and some less. With tech, there's always a more detail to be explored and more learning to be done, even in areas I'm familiar with.
