Software supply chains have emerged as a prime target for cyberattacks, leaving organizations vulnerable to significant financial losses, downtime, reputational damage, and other severe consequences. The staggering financial impact of these attacks is underscored by a recent study by IBM Security, which found that the average cost of a software supply chain attack is a staggering $4.24 million. This alarming figure encompasses not only the immediate costs of remediation but also the long-term ramifications of lost revenue, disrupted operations, and tarnished brand reputation.
To safeguard against these increasingly sophisticated threats, businesses must proactively address common compliance pitfalls and implement robust security measures. The prevalence of these attacks is undeniable: A study revealed that 17% of all breaches start with a supply chain attack. Additionally, a Venafi report found that 82% of CIOs Say Their Software Supply Chains Are Vulnerable.
As organizations strive to fortify their software supply chains, compliance with industry standards emerges as a critical cornerstone. However, achieving and maintaining compliance in the software supply chain is no straightforward task. Numerous compliance frameworks exist, each with its own set of requirements and complexities. Moreover, the rapidly evolving nature of software development and open-source practices makes it challenging to stay up-to-date with the latest compliance requirements and best practices.
Defining compliance in the context of software supply chain security
Let’s start by defining compliance in the context of software supply chain security Cloud Security Alliance identifies “Compliance” as “the management of regulatory or industry compliance standards that are cascaded to teams like information security — as well as legal, risk and audit — to form requirements and policies that shape an organization’s business operations.”
In the Software Supply Chain Security landscape, these standards are set by different compliance frameworks. These frameworks mark best practices and standards that organizations can follow to manage the risks associated with third-party software and services. They provide a structured approach to identifying, assessing, and mitigating vulnerabilities in the software supply chain, ultimately helping organizations achieve their compliance goals.
Prominent software supply chain security frameworks
As previously mentioned, numerous software supply chain security frameworks exist today. Here are some prominent examples:
1. Supply Chain Levels for Software Artifacts (SLSA)
Developed by Google, SLSA defines a multi-level framework for ensuring the integrity and provenance of software artifacts throughout the supply chain. Each level offers distinct security guarantees, ranging from basic signing to attestations of reproducible builds and cryptographic verification. It’s a good fit for organizations seeking a flexible and granular approach to securing their software supply chain.
Key Levels of SLSA:
- Level 1 (Basic Signing): Adds basic signing to artifacts, establishing ownership and preventing tampering.
- Level 2 (Reproducible Builds): Ensures consistent and verifiable builds across environments, with provenance information recorded.
- Level 3 (Cryptographic Verification): Provides cryptographic verification of builds and dependencies, offering strong assurances of authenticity.
- Level 4 (Enhanced Signing & Attestations): Implements advanced signing and attestations for maximum security and tamper detection.
2. CIS Software Supply Chain Security benchmark
Developed by the Center for Internet Security (CIS), a trusted source for security guidelines, this benchmark provides a structured approach to securing software supply chains. It offers prescriptive recommendations across five key stages:
- Source Code: Protect your codebase from unauthorized access and modifications.
- Build Integrity: Ensure the integrity of build processes and artifacts.
- Dependency Management: Securely manage and verify third-party software dependencies.
- Release Integrity: Safeguard software releases from tampering and unauthorized distribution.
- Deployment Integrity: Implement secure practices for deploying software to production environments.
With over 100 recommendations ranging from basic hygiene to advanced controls, the CIS benchmark caters to organizations of all sizes and technical expertise. Its flexible and adaptable nature allows customization to different development environments and technologies.
3. OWASP Software Component Verification Standard
SCVS is an emerging framework developed by the Open Web Application Security Project (OWASP). It aims to establish a standardized approach to verifying the integrity and provenance of software components throughout the supply chain. This framework provides a set of activities, controls, and best practices that can help organizations:
- Gain increased visibility and control over their software components.
- Proactively identify and mitigate security vulnerabilities before they become exploits.
- Align their practices with industry best practices and standards.
4.OpenSSF FLOSS
This voluntary self-assessment program empowers open-source projects to demonstrate their commitment to security and improve their security posture. By following best practices in key areas like dependency management, build integrity, and release signing, projects can earn badges recognized across the open-source ecosystem.
There are many benefits to participating in the OpenSSF Best Practices Badge Program, including:
- Improved security posture: By following the best practices outlined in the program, projects can significantly improve their security posture and reduce the risk of vulnerabilities.
- Increased visibility: Projects that earn badges are recognized for their commitment to security, which can help them attract new users, contributors, and sponsors.
- Community support: The program provides access to a community of security experts who can help projects achieve their security goals.
5. OpenSSF Scorecard
Imagine a security report card for open-source projects. That’s essentially what the Scorecard provides. It analyzes publicly available information to assess the security health of open-source projects across various aspects:
- Dependencies: Identifies and evaluates potential vulnerabilities in third-party software used by the project.
- Build systems: Checks for secure build practices to ensure the integrity of compiled code.
- Release signing: Verifies if releases are digitally signed to prevent tampering.
- Vulnerability disclosure: Assesses the project’s practices for identifying, reporting, and resolving vulnerabilities.
6. Enduring Security Framework (ESF)
ESF Software Supply Chain Security (SSCS) is a comprehensive initiative led by the Enduring Security Framework (ESF) that focuses on securing the entire software development and delivery process. It emphasizes collaboration between public and private entities to address vulnerabilities and mitigate risks throughout the supply chain.
Here are some key aspects of ESF SSCS:
