ANSIBLE IS COMPLETE AUTOMATION
Ansible was written to automate complex multi-
tier deployments, including:
o Configuration managemento App deploymento Provisioningo Servers & network deviceso Cloud management & VMso Zero-downtime rolling
upgradeso Ad-hoc patches & updates
ANSIBLE: THE LANGUAGE OF ENTERPRISE ITo Ansible is the first “infrastructure-as-code” that can be read and
written across IT… from sys-admins to developers to managers
o Ansible is the only automation engine that can automate the entire application lifecycle & continuous delivery pipeline

Ansible Playbook
From development… to production.
HISTORY OF BASELINES
GOLD DISKo Infrequent, time consuming, and error proneo Inconsistent, relies on staff’s capabilityo No ongoing remediation or validation
SEMI-AUTOMATIONo Shell scripts, other toolingo Brittle. Changes really, really hurto No ongoing remediation or compliance
validation
And both of these options suck.
And how do you keep up with changes?

STIG ROLE COVERAGE

We don’t automatically correct every finding, as some are not always safe to run on live systems (i.e. partitioning).
