ANSIBLE IS COMPLETE AUTOMATION Ansible was written to automate complex multi-tier deployments, including: o Configuration management o App deployment o Provisioning o Servers & network devices o Cloud management & VMs o Zero-downtime rolling upgrades o Ad-hoc patches & updates

ANSIBLE: THE LANGUAGE OF ENTERPRISE IT o 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 DEV/TES T Q/AOPERATIONSMANAGEMENTINFRASTRUCTU RE Ansible Playbook From development…to production.

HISTORY OF BASELINES GOLD DISK o Infrequent, time consuming, and error prone o Inconsistent, relies on staff’s capability o No ongoing remediation or validation SEMI-AUTOMATION o Shell scripts, other tooling o Brittle. Changes really, really hurt o No ongoing remediation or compliance validation

And both of these options suck. And how do you keep up with changes?

ANSIBLE AND SECURITY BASELINES REPEAT o Same process every time REMEDIATE o Apply STIG whenever desired VALIDATE o Confirm compliance IDEMPOTENT o Run and re-run over and over

HOW MINDPOINT GROUP o Trusted o Capable RHEL 6.x (and variants) o Very common DISA STIG o Significant pain points for USG customers o SCAP for easy validation

STIG ROLE COVERAGE CAT 1 (HIGH): 100% CAT 2 (MEDIUM): 91% CAT 3 (LOW): 82% We don’t automatically correct every finding, as some are not always safe to run on live systems (i.e. partitioning).
