h2. *Summary*

Implement automated Software Bill of Materials (SBOM) generation for Apache Geode to enhance supply chain security, improve dependency transparency, and meet modern compliance requirements for enterprise deployments.
h3. *Background*

Apache Geode currently lacks comprehensive dependency tracking and supply chain visibility, which creates challenges for:
* Security vulnerability assessment across 8,629 Java files and 30+ modules
* Enterprise compliance requirements (NIST, CISA guidelines)
* Dependency license compliance verification
* Supply chain risk management

h3. *Current State Analysis*
* {*}Dependency Management{*}: Centralized in DependencyConstraints.groovy with 70+ external libraries
* {*}Build System{*}: Gradle 7.3.3 with modular architecture (geode-core, geode-gfsh, geode-lucene, etc.)
* {*}Security Scanning{*}: Basic CodeQL in GitHub Actions, no dependency vulnerability scanning
* {*}Compliance Tools{*}: Limited to basic license headers and Apache RAT

h3. *Business Justification*
# {*}Security Compliance{*}: Meet NIST SSDF and CISA requirements for federal deployments
# {*}Enterprise Adoption{*}: Fortune 500 companies increasingly require SBOM for procurement
# {*}Supply Chain Security{*}: Enable rapid response to zero-day vulnerabilities (Log4Shell-like events)
# {*}License Compliance{*}: Automated verification of 3rd party library licenses
# {*}DevSecOps Integration{*}: Foundation for advanced security scanning and monitoring

h2. *🎯 Acceptance Criteria*
h3. *Primary Requirements*
*  Generate SPDX 2.3 format SBOM for all release artifacts
*  Include both direct and transitive dependencies with version information
*  Capture license information for all components
*  Generate SBOMs for multi-module builds (30+ Geode modules)
*  Integrate with existing Gradle build pipeline
*  Support both JSON and XML output formats

h3. *Technical Requirements*
*  No increase in build time >5%
*  Compatible with current Gradle 7.3.3 (prepare for Gradle 8+ migration)
*  Generate separate SBOMs for different distribution artifacts:
  ** apache-geode-\\{version}.tgz (full distribution)
  ** geode-core-\\{version}.jar
  ** geode-gfsh-\\{version}.jar
  ** Docker images
*  Include vulnerability database integration capabilities

h3. *Quality Gates*
*  SBOM validation against SPDX specification
*  All dependencies properly identified with CPE identifiers where applicable
*  License compatibility verification
*  Automated regression testing

----
h2. *🔧 Technical Implementation Plan*
h3. *Phase 1: Core SBOM Generation (Sprint 1-2)*

// Add to root build.gradle
plugins

{     id 'org.spdx.sbom' version '0.8.0' }

sbom {
    targets {
        release {
            scopes = ['runtimeClasspath', 'compileClasspath']
            configurations = ['runtimeClasspath']
            outputDir = file("${buildDir}/sbom")
            outputName = "apache-geode-${version}"
        }
    }
}
 
 
h3. *Phase 2: Multi-Module Integration (Sprint 3)*
* Configure SBOM generation for each Geode module
* Aggregate module SBOMs into distribution-level SBOM
* Handle inter-module dependencies correctly

h3. *Phase 3: CI/CD Integration (Sprint 4)*

 
 
# Add to .github/workflows/

- name: Generate SBOM
  run: ./gradlew generateSbom
  
 - name: Validate SBOM
  uses: anchore/sbom-action@v0
  with:
    path: ./build/sbom/
    
 - name: Upload SBOM Artifacts
  uses: actions/upload-artifact@v3
  with:
    name: sbom-files
    path: build/sbom/
 
 
h3. *Phase 4: Enhanced Security Integration (Sprint 5)*

* Vulnerability scanning integration with generated SBOMs
* License compliance verification
* Supply chain risk assessment
