Supply Chain Security - OWASP Top 10

Supply Chain Security is a critical aspect of the OWASP Top 10 vulnerabilities, focusing on risks associated with software supply chains. This lesson covers key concepts, best practices, and steps for enhancing the security of software supply chains.

2.1 Definition of Supply Chain Security

Supply Chain Security involves protecting the integrity, confidentiality, and availability of products and information as they move through the supply chain, from suppliers to customers.

2.2 Key Terms

• **Supply Chain**: The network between a company and its suppliers to produce and distribute a specific product.
• **Integrity**: Assurance that software and data have not been altered or tampered with.
• **Confidentiality**: Ensuring that sensitive information is accessed only by authorized parties.

3.1 Implement Code Signing

Code signing verifies the integrity and authenticity of software. Use digital signatures to ensure that your source code has not been altered.

3.2 Regular Audits and Assessments

Conduct regular security audits of third-party components and libraries to identify vulnerabilities.

3.3 Supply Chain Risk Management

Develop a risk management strategy that includes:

1. Identifying critical components in the supply chain.
2. Assessing the security posture of suppliers.
3. Implementing mitigation strategies for identified risks.

3.4 Continuous Monitoring

Establish a system for continuous monitoring of supply chain components to detect and respond to incidents promptly.

3.5 Security Training for Developers

Provide security training for developers to help them recognize and mitigate supply chain risks.
