Practical Unix and Internet Security (Repost)

Practical Unix & Internet Security is on its second edition, and its maturity shows. To call this highly readable book comprehensive is an understatement. The breadth is vast, from fundamentals (definitions of computer security; the history of Unix) and commonsense but little-observed security basics (making backups; physical and personnel security; buggy software) to modern software (NFS, WWW, firewalls) and the handling of security incidents. The section on users and passwords alone is 21 pages long–and worth every page. Useful appendices include a Unix security checklist, a list of emergency response organizations, and many references to electronic and paper resources.
