Meta Description
Learn STIG baseline hardening for RHEL/CentOS servers. Automate security compliance in 10 minutes instead of 40+ hours with production-tested Ansible playbooks.

What is STIG hardening, and why does it matter for your RHEL infrastructure?
If you manage Linux servers in regulated industries—government, finance, healthcare, defense—you’ve probably heard of STIG compliance. But if you’re still hardening servers manually, you’re spending way too much time on repetitive, error-prone configuration.
This guide covers STIG baseline hardening and how to automate it so you can deploy compliant servers in minutes.
What Is STIG?
STIG stands for Security Technical Implementation Guide. It’s a set of security standards created by DISA (Defense Information Systems Agency) for securing IT systems, especially critical for:
- Government agencies and contractors
- Financial institutions
- Healthcare organizations
- Any organization with compliance requirements
STIG baseline controls cover:
- Kernel parameter hardening
- SSH security configuration
- Firewall setup
- SELinux enforcement
- Audit logging
- File permission hardening
- Service hardening Why Manual Hardening Takes So Long
Hardening a single RHEL server manually involves dozens of configuration steps:
- Configuring SSH (disable root login, key-based auth only, change defaults)
- Setting up firewall rules (firewalld configuration)
- Enforcing SELinux (context policies, boolean settings)
- Configuring audit logging (auditd, rsyslog)
- Setting file permissions on critical system files
- Disabling unnecessary services
- Setting kernel parameters (sysctl configuration)
- Configuring password policies
- Testing and verification
Each step requires:
- Researching correct settings
- Manual command execution
- Verification it worked
- Documentation of what changed
For a single server, this takes 40-50 hours. For 10 servers, that’s 400+ hours of work.
And if you miss a step? You’re not STIG-compliant.
The Automated Solution
Instead of manual configuration, use Ansible playbooks to automate baseline STIG hardening.
What automation gives you:
- Consistent hardening across all servers (no missed steps)
- Deployment in 10-20 minutes per server (not 40+ hours)
- Repeatable process (deploy 100 servers the same way)
- Full documentation (exactly what was configured)
- Version control (track changes to playbooks)
- Easy to customize (modify playbooks for your policies)
We built production-tested Ansible playbooks that handle baseline STIG hardening automatically. Deploy to any new RHEL/CentOS/Rocky/AlmaLinux server in minutes.
How It Works
- Provision – Create new server on cloud provider (DigitalOcean, Linode, AWS)
- Prepare – Update OS, add to Ansible inventory
- Run – Execute playbook (answers 2 prompts: hostname and IP)
- Done – Server is STIG baseline hardened
That’s it. No manual configuration needed.
What Gets Hardened
- OS Parameters – Kernel hardening, system limits
- SSH – Key-based auth, disable root, strict settings
- Firewall – firewalld rules, network policies
- SELinux – Enforce mode, proper contexts
- Audit Logging – auditd, system audit trail
- Services – Disable unnecessary, harden enabled
- File Permissions – Critical files locked down
All configured automatically, consistently, and documented.
Example: SSH Hardening
Manual approach:
- Edit /etc/ssh/sshd_config (15 min)
- Set PermitRootLogin no (find line, uncomment, set value)
- Set PubkeyAuthentication yes
- Set PasswordAuthentication no
- Test SSH still works
- Restart SSH
- Verify changes
- Document what changed
Automated approach:
- Run playbook
- Answer: hostname and IP
- Done (60 seconds) Getting Started
