Is there a tool or understandable source (manual, webpage, ...) in existence that helps a moderate* user to be more sensible about user permissions?
In my ideal-dream-world I'd have a CLI tool that lets you scan your system or a directory to find security loopholes and gives you a sensible, readable feedback on how one could improve one's security.
I mean "security" in the online generation's way: how to keep my machine (which is running arch btw) from being infiltrated by a virus, a worm, ... I'm not bothered by "my little brother will ruin my system" and tangent problems.
Does this kind of tool exist?
Jeesh: I sound like a windows user here: being paranoid about security and all. I just switched from mac - where I've never had any security problems - to linux. Although I know security is pretty baked in to unix with the concept permissions, I do feel a bit exposed because I'm not quite sure how much the safety my mac offered me was part of Mac in stead of unix. There must be some exploits a malicous party can use on the linux, no?
*a moderate user is a person that knows how to use the CLI (in fact I prefer to use the CLI) etcetera, but isn't the typ of person to compile his own version linux.
