What are the main differences between Linux and Windows (and Unix), in terms of security? Security in Windows 2000/XP/2003...
is in many ways similar to UNIX; it also has many important differences. Some of them are:
- file security is a bit more granular in Windows than in most popular UNIX variants,
- Windows security is configured through binary registry while UNIX uses text configuration files in /etc/ (which makes UNIX security configuration much more transparent),
- kernel security model is different,
- network service security is different, etc.
