Daryl wants to know if Linux is 100% secure. Leo says no, that standard isn't possible, but it is more secure than Windows. Why does Windows have so many vulnerabilities? Leo says that Windows has gotten better over time, but because Microsoft supports legacy code for older machines, it leaves Windows users vulnerable. Linux was written from the ground up to be more secure and it doesn't carry the burden to be "all things to all people." Since it's based on UNIX's permissions system, it's more secure.
