U.S. CISA Secure Software Development Attestation Form (SSDAF) — Secure Software Self-Attestation Requirements

Why it Matters

The U.S. CISA Secure Software Development Attestation Form (SSDAF)strengthens trust by ensuring organizations follow secure softwaredevelopment practices and regulatory requirements.

Key benefits include:

• Support stronger supply chain security

Require softwareproviders to attest to secure development, limiting risks fromthird-party software procurement and integration.

• Enhance regulatory compliance

Enableorganizations to demonstrate alignment with federal cybersecuritystandards, improving their ability to meet compliance obligationsduring audits.

• Increase software transparency

Promote greatervisibility into suppliers' development practices, enabling informedrisk management and procurement decisions.

• Improve incident response readiness

Mandate securedevelopment controls that reduce exploitable vulnerabilities andsupport more effective detection and remediation of software-basedthreats.

• Strengthen organizational reputation

Provide assuranceto customers and stakeholders regarding the security integrity ofdeployed software products and internal development processes.

How it Works

The U.S. CISA Secure Software Development Attestation Form (SSDAF)structures secure software development requirements around a set ofsecurity controls, process safeguards, and regulatory criteriaaligned with executive orders and federal guidelines. The frameworkestablishes a formal lifecycle for assessing software supply chainrisks and codifies key security practices into defined domains suchas source code integrity, vulnerability management, and securedevelopment methods. Organizations are required to self-attest to theimplementation of these controls as part of compliance with federalprocurement requirements.

In practice, organizations apply the SSDAF by integrating its controlrequirements into their secure development lifecycle (SDLC), mappingthe framework’s standards to internal governance policies, andconducting regular compliance assessments. Security teams implementcontrols such as code review processes, automated vulnerabilityscanning, and developer training to address compliance gaps. Ongoingmonitoring and document collection support continuous alignment withSSDAF expectations and facilitate timely incident response andremediation.

Through SmartSuite, organizations streamline SSDAF operationalizationby leveraging pre-built control libraries tailored to secure softwaredevelopment, managing risks within configurable registers, andenforcing policy governance workflows. The platform’s evidencecollection features support audit readiness, while compliancetracking modules and reporting dashboards enable ongoing monitoringof software supply chain security practices and regulatory adherence.

Key Elements

• Secure Software Development Practices

Specifiesrequired processes for building software that address securityconsiderations throughout the development lifecycle.

• Supplier Risk Management Controls

Outlinesmechanisms for evaluating and managing third-party and supply chainsoftware risks.

• Secure Software Design Standards

Establishesminimum standards for secure architecture and coding within developedapplications.

• Vulnerability Management Requirements

Describesprocedures for identifying, disclosing, and remediatingvulnerabilities in delivered software.

• Continuous Monitoring Activities

Provides forongoing oversight and review of software to ensure continuedcompliance with security requirements.

• Attestation and Documentation Processes

Defines necessaryevidence and documentation to support self-attestation of securesoftware development.

Framework Scope

The U.S. CISA Secure Software Development Attestation Form (SSDAF) isadopted by software producers contracting with U.S. federal agencies,addressing the development and delivery of secure software running onfederal information systems and cloud services. Organizationstypically complete the SSDAF when demonstrating control effectivenessand meeting federal supply chain security requirements.

Framework Objectives

The U.S. CISA Secure Software Development Attestation Form (SSDAF)defines key outcomes for secure software practices and organizationalcompliance.

Strengthen cybersecurity governance through formalized securesoftware development processes

Enhance risk management by addressing vulnerabilities in softwaresupply chains

Promote regulatory compliance with federal security and privacyrequirements

Improve data protection through implementation of robust securitycontrols

Support operational resilience by ensuring software integrity andtrustworthiness

Demonstrate audit readiness and transparency in software developmentpractices The U.S. CISA Secure Software Development Attestation Form(SSDAF) aligns with secure development practices found in NIST SP800-218, NIST SP 800-53, and the OWASP Software Assurance MaturityModel. Organizations typically implement SSDAF to fulfill federalprocurement requirements, regulatory compliance, or to demonstratesecure software development practices to government customers.
