It also benefits from being open source as well as being a niche OS, which means there's less malware targeting it. In reality though, unless you have reasons to believe you ...

While the permissions of the parent directory will still be applied, these may be harder to administer than the permissions on the socket file itself. Unix domain sockets provide another means for verifying the ...

The four ring system was designed by Intel for anyone to use, and Microsoft chose a scheme to simplify development work and provide a faster OS at the cost of some security. As far as Microsoft is concerned, they haven't been phased out, so much as they were never used to begin with. Microsoft didn't ask Intel to make a two ring system; Intel provided a four ...
