Assessment Tools
OpenSCAP
# Install
apt install openscap-scanner scap-security-guide
# Run CIS benchmark scan
oscap xccdf eval \
--profile xccdf_org.ssgproject.content_profile_cis \
--results results.xml \
--report report.html \

Lynis
# Install
apt install lynis
# Run audit
lynis audit system
# Generate report
lynis audit system --report-file /tmp/lynis-report.dat
InSpec
# cis-profile/controls/ssh.rb
control 'cis-ssh-1' do
impact 1.0
title 'Ensure SSH root login is disabled'
describe sshd_config do
its('PermitRootLogin') { should eq 'no' }
end
end
control 'cis-ssh-2' do
impact 0.7
title 'Ensure SSH password authentication is disabled'
describe sshd_config do
its('PasswordAuthentication') { should eq 'no' }
end
end
# Run InSpec
inspec exec cis-profile -t ssh://user@target
Kubernetes CIS
# kube-bench
docker run --rm -v /etc:/etc:ro -v /var:/var:ro \
aquasec/kube-bench:latest run --targets node
# Check specific sections
kube-bench run --targets master --check 1.1,1.2
Remediation Workflow
workflow:
1_scan:
- Run automated assessment
- Generate baseline report
2_analyze:
- Review findings
- Identify false positives
- Prioritize by risk
3_remediate:
- Apply fixes
- Document exceptions
- Verify changes
4_validate:
- Re-run assessment
- Confirm remediation
- Generate compliance report
Best Practices
- Baseline before hardening
- Document exceptions
- Automate assessments
- Track compliance over time
- Regular re-assessment
- Version control configurations
