Sudo Mastery, 2nd Edition

Sudo: You're Doing It Wrong
Unix-like operating systems use a rudimentary access control system: the root account can do anything, while other users are peasants with only minimal access. This worked fine in UNIX's youth, but now that sysadmin responsibilities are spread among many people and applications, many people need a tiny slice of root's power.
Sudo lets you divide root's monolithic power between the people who need it with accountability and auditability.
Sudo Mastery will teach you to:
design a secure sudo policy
simplify policies with lists and aliases
manage shell environments
verify system integrity via intrusion detection
deploy a single sudo policy across your enterprise
manage sudo policies via LDAP
log and debug sudo
record and replay full sudo sessions
use authentication systems other than passwords
Master sudo with Sudo Mastery!
