"$image" =~ ^[a-zA-Z0-9._/-]+:[a-zA-Z0-9._-]+$ ]]; then echo "ERROR: Invalid Docker image format: $image" return 1 fi return 0 } ``` 2. **Apply validation to all user inputs** 3. **Add bounds checking for numerical inputs** 4. **Sanitize file paths consistently** ## Priority 3: Maintenance and Monitoring (Complete within 30 days) ### 3.1 Automated Security Scanning **Effort:** 2-3 hours setup + ongoing maintenance **Implementation Steps:** 1. **Add ShellCheck to CI/CD:** ```yaml # .github/workflows/security.yml name: Security Scan on: [push, pull_request] jobs: shellcheck: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Run ShellCheck uses: ludeeus/action-shellcheck@master with: severity: warning ``` 2. **Weekly security script:** ```bash #!/bin/bash # weekly-security-scan.sh find . -name "*.sh" -exec shellcheck {} \; # Additional security tools as needed ``` **Acceptance Criteria:** - [ ] Automated ShellCheck on all commits - [ ] Weekly security scan implemented - [ ] Security issues tracked and resolved - [ ] Documentation updated ### 3.2 Security Documentation **Effort:** 4-6 hours **Deliverables:** - [ ] Security standards document - [ ] Incident response procedures - [ ] Security training materials - [ ] Regular review schedule ## Priority 4: Long-term Improvements (Complete within 60 days) ### 4.1 Security Architecture Review **Scope:** Overall security architecture and practices **Effort:** 8-12 hours **Activities:** - Review all inter-script dependencies - Analyze privilege requirements across the stack - Design secure defaults and configurations - Implement defense-in-depth strategies ### 4.2 Security Testing Framework **Scope:** Automated security testing **Effort:** 12-16 hours **Deliverables:** - Automated vulnerability scanning - Penetration testing procedures - Security regression testing - Performance impact assessment ## Implementation Timeline ### Week 1 (Priority 1) - [ ] Day 1-2: Fix curl | bash patterns in setup scripts - [ ] Day 3-4: Test and validate fixes - [ ] Day 5: Security review and documentation update ### Week 2 (Priority 2) - [ ] Day 1-3: Address excessive privilege usage - [ ] Day 4-5: Implement enhanced input validation - [ ] Weekend: Testing and validation ### Week 3-4 (Priority 3) - [ ] Week 3: Implement automated security scanning - [ ] Week 4: Complete security documentation ### Week 5-8 (Priority 4) - [ ] Ongoing: Security architecture review - [ ] Ongoing: Security testing framework development ## Resource Requirements ### Development Time - **Priority 1:** 8-12 hours total - **Priority 2:** 16-20 hours total - **Priority 3:** 12-16 hours total - **Priority 4:** 20-28 hours total ### Skills Required - Shell scripting expertise - Security best practices knowledge - CI/CD pipeline configuration - System administration ### Tools Needed - ShellCheck - Git hooks for security scanning - Testing environments (Docker) - Security scanning tools ## Success Metrics ### Security Improvements - [ ] 0 critical vulnerabilities - [ ] <5 high-risk issues - [ ] 100% of scripts pass security checks - [ ] All curl | bash patterns eliminated ### Process Improvements - [ ] Automated security scanning implemented - [ ] Security review process established - [ ] Documentation complete and up-to-date - [ ] Team trained on security practices ### Compliance Measures - [ ] Security checklist adopted - [ ] Regular security reviews scheduled - [ ] Incident response procedures tested - [ ] Security metrics tracked and reported ## Risk Management ### Implementation Risks - **Functionality Impact:** Thorough testing required for all changes - **Timeline Pressure:** Prioritize critical fixes, defer non-critical items if needed - **Resource Availability:** Ensure dedicated time for security work ### Mitigation Strategies - Implement changes in isolated branches - Require peer review for all security changes - Maintain rollback procedures for all modifications - Test in staging environment before production deployment ## Communication Plan ### Stakeholder Updates - **Weekly:** Progress updates to development team - **Bi-weekly:** Status reports to management - **Monthly:** Security metrics and trend analysis ### Escalation Procedures - **Blocked Issues:** Escalate within 24 hours - **New Critical Findings:** Immediate escalation - **Timeline Risks:** Weekly assessment and communication --- **Document Owner:** Security Team **Last Updated:** $(date '+%Y-%m-%d') **Next Review:** $(date -d '+30 days' '+%Y-%m-%d') **Approval Required:** Development Team Lead, Security Officer **Change Control:** All modifications to this plan require documented approval
