What are the correct permissions for the /tmp, /usr/tmp, and /var/tmp directories?
All of these directories should be owned by bin, group bin, mode 1777. This turns on the sticky bit, so that the only people who can remove a file from these directories are the owner and root. 4.2 : Available kernel add-ons 4.2.1 : Loadable Kernel Modules Several strides have been made in the past to reduce the amount of ‘cruft’ that gets into the default kernel. One way is to make the kernel so hard to use that practically no one but a person with precisely the ‘right’ hardware would be able to use the system Another way is to implement something called ‘LKM’s or “Loadable Kernel Modules”. These are run-time extensions to the system that allow the distribution kernel to not include things that people might want, but not nxbeed until they get the system up and running. While the security concerns of LKMs are valid, their implementation is such a win that the research to implement them is well worth it. It was really _very_ simple to make these, so this is nothing spectacular. Just som
