ROADMAP • OpenStack Security Guide begins 24-JUNE-2013 • Content will be incorporated into SCAP Security Guide • Formation of Red Hat OpenStack STIG (eta Q4 2013) • Want to participate? • https://fedorahosted.org/scap-security-guide/ We need your feedback to prioritize other tech! • OpenShift vs JBoss vs Red Hat Storage vs ……..

APPENDIX I: Additional SSG Project Info 29
• Delivers practical security guidance, baselines, and associated validation mechanisms using the Security Content Automation Protocol (SCAP) • Current content for RHEL6, JBoss EAP5 • Upstream source for government implementation guidance • Specifically, DISA STIG and NSA SNAC Guide • First example of US Government policy, not just technology, derived from community open source project!
• Open Source project • https://fedorahosted.org/scap-security-guide (and yes, government can contribute!) (and yes, we checked with the lawyers) • Why? • • Enables agile government—vendor—consumer interaction Ensures consensus among stakeholders • Enables development in SCAP formats
• Recommendations map to compliance standards wherever possible • Because of this mapping, creation of custom “profiles” possible • RHEL6 STIG • RHEL6 Security Guide (via NSA) • Baseline content for FedRAMP • Your own?
• SCAP Formats • XML schemas, managed by NIST • Configuration checklist / guide format is XCCDF • Automated checking via OVAL
• COSTS • Complex XML schema • OVAL just a bit verbose </understatement> • BENEFITS • Ingestible by SCAP-compatible tools • OpenSCAP ships within RHEL! • XCCDF Profiles • Standardized outputs/reporting
APPENDIX: USAGE DEMO 35
USE THE WORKBOOK! • Available on wiki: https://fedorahosted.org/scap-security-guide/
STEP 1: DOWNLOAD • RPM yum repository (EPEL) $ sudo sh -c “wget -O /etc/yum.repos.d/epel-6-scap-security-guide.repo \ http://repos.fedorapeople.org/repos/scap-security-guide/epel-6-scap-securityguide.repo” $ sudo sh –c “yum install scap-security-guide” ” • Source Code $ git clone ssh://git.fedorahosted.org/git/scap-security-guide.git ” • Note: RPMs place files into /usr/share/xml/scap/ssg
STEP 2: REVIEW GUIDANCE • HTML guides located in /usr/share/xml/scap/ssg/guides/ • As of SSG v0.1-11, shipping EAP5 and RHEL6 guides $ firefox \ /usr/share/xml/scap/ssg/guides/rhel6-guide.html”
STEP 3: REVIEW POLICY MAPPINGS • Policy mappings located in /usr/share/xml/scap/ssg/policytables/ • Frequently used as Security Requirements Traceability Matrix (STRM) foundations $ firefox \ /usr/share/xml/scap/ssg/policytables/table-rhel6nistrefs.html”
STEP 4: RUN A SCAN $ sudo sh -c “oscap xccdf eval −−profile stig-rhel6-server \ −−results /root/ssg-results.xml \ −−report /root/ssg-results.html \ −−cpe /usr/share/xml/scap/ssg/content/ssg-rhel6-cpedictionary.xml \ /usr/share/xml/scap/ssg/content/ssg-rhel6-xccdf.xml”

STEP 6: GENERATE REMEDIATION SCRIPTS As of SSG v0.1-11 (e.g. June 2013) this feature is undergoing rapid development. Not complete, not fully tested, not ready for production! $ oscap xccdf generate fix \ —result-id xccdf_org.open-scap_testresult_stig-rhel6-server \ /var/www/html/results/results.xml “
