CRA Policy Template
Secure Software Development Policy
1. Introduction
1.1 Purpose and Scope: This Secure Software Development Policy (SSDP) establishes a comprehensive framework for developing and maintaining secure software products within [Organization Name]. The policy aims to minimize vulnerabilities and protect against cyber threats throughout the software development lifecycle (SDLC). This applies to all software developed, acquired, or maintained by the organization, including but not limited to web applications, mobile applications, internal systems, and third-party integrations.
1.2 Relevance to CRA: This SSDP directly addresses the Canadian Revenue Agency (CRA) requirements for the protection of sensitive taxpayer data and the maintenance of robust cybersecurity controls. It aligns with CRA's expectations for secure software development practices, contributing to compliance with relevant legislation, regulations, and internal policies regarding data privacy, security, and operational integrity. This policy helps mitigate risks associated with non-compliance, including potential fines, reputational damage, and legal repercussions.
2. Key Components
This SSDP comprises the following key components:
Secure Requirements Gathering and Design: Defining security requirements early in the SDLC.
Secure Coding Practices: Implementing secure coding techniques throughout development.
Security Testing and Verification: Conducting thorough security testing at various stages.
Vulnerability Management: Identifying, assessing, and remediating vulnerabilities.
Secure Deployment and Operations: Ensuring secure deployment and ongoing operational security.
Security Awareness Training: Educating developers and other stakeholders on security best practices.
Third-Party Vendor Management: Managing security risks associated with third-party software and services.
3. Detailed Content
3.1 Secure Requirements Gathering and Design:
In-depth explanation: Security considerations must be integrated into all phases of the SDLC, starting with requirements gathering and design. This involves identifying potential security risks and incorporating appropriate security controls into the system architecture and design.
Best practices: Utilize threat modeling techniques (e.g., STRIDE, PASTA) to identify potential threats and vulnerabilities. Incorporate security requirements into user stories and design documents. Employ security design principles (e.g., least privilege, defense in depth).
Example: A new tax processing application requires secure authentication. The design documents explicitly specify the use of multi-factor authentication (MFA) and strong password policies, complying with CRA's standards for access control.
Common pitfalls: Neglecting security considerations until later stages of development; insufficient threat modeling; relying solely on default security settings.
3.2 Secure Coding Practices:
In-depth explanation: Developers must adhere to secure coding guidelines and best practices to minimize vulnerabilities in the codebase. This includes using secure libraries, avoiding common vulnerabilities (OWASP Top 10), and performing regular code reviews.
Best practices: Follow secure coding standards (e.g., OWASP Secure Coding Practices); use static and dynamic application security testing (SAST/DAST) tools; perform regular code reviews with security experts; utilize secure coding style guides.
Example: A developer uses parameterized queries to prevent SQL injection vulnerabilities when interacting with a database containing taxpayer information. They also sanitize all user inputs to avoid cross-site scripting (XSS) attacks.
Common pitfalls: Using outdated libraries; neglecting input validation; hardcoding sensitive information; failing to handle exceptions properly.
3.3 Security Testing and Verification:
In-depth explanation: Thorough security testing is crucial to identify and mitigate vulnerabilities before deployment. This involves various testing methodologies, including penetration testing, static and dynamic analysis, and vulnerability scanning.
Best practices: Conduct penetration testing by certified security professionals; utilize automated SAST/DAST tools; perform code reviews; integrate security testing into the CI/CD pipeline.
Example: A penetration test reveals a vulnerability in the authentication mechanism of a new online portal. This vulnerability is then remediated before the application is deployed to production.
Common pitfalls: Inadequate testing coverage; insufficient expertise in security testing; ignoring test results; not prioritizing critical vulnerabilities.
3.4 Vulnerability Management:
In-depth explanation: Establish a process for identifying, assessing, and remediating security vulnerabilities throughout the software lifecycle.
Best practices: Use vulnerability scanners; implement a vulnerability management system; prioritize vulnerabilities based on risk; track remediation efforts; conduct regular security assessments.
Example: A vulnerability scanner detects a known vulnerability in a third-party library used in an existing application. The vulnerability is assessed for risk, and a patch is applied promptly.
Common pitfalls: Failure to monitor for vulnerabilities; delaying remediation; insufficient risk assessment; lack of communication about vulnerabilities.
3.5 Secure Deployment and Operations:
In-depth explanation: Secure deployment practices minimize the risk of vulnerabilities being introduced during deployment. Ongoing operational security includes monitoring for threats and vulnerabilities in the deployed system.
Best practices: Employ secure configuration management; use secure deployment tools; monitor system logs; implement intrusion detection and prevention systems; regularly update software and libraries.
Example: The deployment process includes automated security checks and validation steps to verify the integrity and security of the deployed application.
Common pitfalls: Manual deployment processes; neglecting security hardening of servers; inadequate logging and monitoring; delayed patching.
3.6 Security Awareness Training:
In-depth explanation: Regular security awareness training for developers and other stakeholders is essential to improve security practices and reduce human error.
Best practices: Provide regular training on secure coding practices, security threats, and best practices; conduct phishing simulations; use interactive training modules.
Example: Developers are trained on the OWASP Top 10 vulnerabilities and best practices for preventing them.
Common pitfalls: Infrequent training; lack of engagement in training; failure to update training materials.
3.7 Third-Party Vendor Management:
In-depth explanation: Manage the security risks associated with third-party software and services used in the organization's applications.
Best practices: Conduct thorough due diligence on third-party vendors; require security assessments from vendors; monitor vendor performance; include security clauses in contracts.
Example: Before using a cloud-based service, a security assessment is conducted to ensure the service meets the organization's security requirements.
Common pitfalls: Lack of due diligence; failing to monitor vendor security performance; insufficient contractual security requirements.
4. Implementation Guidelines
1. Establish a Secure Development Team: Create a cross-functional team with security expertise to oversee the implementation of this policy.
2. Develop Secure Coding Standards: Define clear and comprehensive secure coding standards based on industry best practices (e.g., OWASP).
3. Implement Security Testing Procedures: Integrate security testing into the SDLC, including static and dynamic analysis, penetration testing, and vulnerability scanning.
4. Establish a Vulnerability Management Program: Develop a process for identifying, assessing, and remediating vulnerabilities.
