Software Attestation: Safeguard Your Systems Against Tampered Code #
Software attestation is a crucial cybersecurity process that ensures your software components are authentic, untampered, and meet security standards before they’re deployed. This process, along with SBOM attestation, is essential for organizations managing complex software supply chains, making sure that software remains uncompromised from development to deployment.

What is Software Attestation
Software attestation ensures that software running on a system is genuine, unaltered, and secure. By generating and validating cryptographic evidence, organizations can confirm the integrity and origin of software components throughout their lifecycle. In an era where software supply chain security is increasingly complex and vulnerable, software attestation becomes critical in protecting against unauthorized modifications, safeguarding both the software’s integrity and the broader system’s security.
Why Software Attestation is Essential #
Trusted software is key to maintaining security. Attestation ensures that software components, especially those from third-party vendors, stay uncompromised. This factor becomes crucial for environments handling sensitive data or critical infrastructure.
Furthermore, SBOM attestation enhances security by verifying the legitimacy and security of all components listed in a Software Bill of Materials (SBOM). As SBOMs become more prevalent in software supply chains, this type of attestation is vital for maintaining compliance and trust.
Recently, the Biden administration highlighted the importance of this process by pushing to strengthen cybersecurity across the federal government. In response to increasing threats, Executive Order 14028 set stricter standards for software development. This initiative led the Cybersecurity and Infrastructure Security Agency (CISA) to release a secure software development attestation form. This form ensures that software producers working with the federal government follow secure development practices.
This action marks a significant step in protecting government systems from supply chain attacks, such as the SolarWinds breach. It also establishes a benchmark for the private sector, encouraging companies to adopt secure-by-design principles. By prioritizing software attestation, organizations not only meet these new standards but also bolster their overall security posture in an interconnected world.
Practical Applications of Software Attestation
Software attestation is particularly relevant in industries where security is paramount, such as finance, healthcare, and government. For instance, financial institutions might use software attestation to ensure that all software deployed in their infrastructure complies with the Digital Operational Resilience Act (DORA). Additionally, healthcare providers may require SBOM attestation to verify that medical software is free from vulnerabilities and secure for patient data.
Furthermore, in modern CI/CD pipelines, software attestation plays a critical role in protecting against artifact poisoning. As discussed in Xygeni’s blog, artifact poisoning occurs when attackers inject malicious code into software artifacts during the build process. Software attestation mitigates this risk by ensuring that only verified, secure artifacts get deployed and preventing compromised code from entering production environments
How Software Attestation Works #
Software attestation typically involves cryptographic techniques, where a component like a TPM or a secure enclave generates a cryptographic signature based on the software’s current state. An external entity then verifies this signature to ensure the software hasn’t been altered.
For example, in application security, a system might perform attestation checks before launching a critical process, confirming that the software hasn’t been compromised since its last verification. This method ensures continuous trustworthiness and proves essential in environments where maintaining software integrity is non-negotiable.
Benefits of Implementing Software Attestation #
Software attestation is vital for preventing unauthorized modifications to software, which could lead to security breaches. It ensures that all software components are secure, reliable, and compliant with industry standards, thereby reducing the risk of introducing vulnerabilities into production environments.
Key Benefits
- Enhanced Security: Software attestation verifies the integrity of software components, preventing the deployment of compromised or malicious code.
- Compliance Assurance: It ensures that software meets regulatory requirements, such as those outlined in DORA or NIST standards.
- Protection Against Artifact Poisoning: By verifying software artifacts, software attestation protects CI/CD pipelines from the risks associated with artifact poisoning.
- Transparency and Trust: SBOM attestation provides detailed visibility into the software supply chain, fostering trust between software producers and consumers.
Challenges in Software Attestation #
Organizations often struggle with the complexity of managing software attestation across diverse environments and multiple software components. Additionally, ensuring that the attestation process integrates seamlessly into the software development lifecycle (SDLC) without causing delays can be challenging.
