There are some best practices used by major distributions, for example:

- mandatory access control (SELinux, for example),
- firewall by default,
- policykit fine-grained privilege control,
- buffer overflow protection,
- restricted kernel memory access to stop many rootkits,
- higher level hashing for passwords

However, the weakest link is always system administration, and any OS can fall victim to human error.

In one case, on windows, applications can self execute themselves, and install viruses and such. Linux has different levels of permissions, and always requires explicit authentication to execute programs, thus preventing a lot of viruses.
