Sudo Mastery

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
