ASD enforces stricter security standards for software developers

🔑 Enhanced Key Takeaways

•The updated ISM introduces a specific control (ISM-2121) explicitly stating that software developers lacking sufficient cybersecurity knowledge and skills for their projects should not be utilized, emphasizing a 'secure by default' approach where software is secure out-of-the-box.
•The ISM now recommends that organizations maintain a register of developers' cybersecurity knowledge and skills, and encourages training or upskilling in secure coding and programming practices.
•Beyond traditional software, the ISM's guidelines for software development also extend to artificial intelligence (AI) applications and AI models, including recommendations for storing AI models in non-executable file formats and mitigating OWASP Top 10 risks for Large Language Model (LLM) applications.
•The ISM emphasizes the use of 'Secure by Design' principles, memory-safe programming languages (such as C#, Go, Java, Ruby, Rust, and Swift), threat modeling, and comprehensive security testing methods like Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA).
•The ISM is part of a broader global effort to secure the software supply chain, with its guidelines focusing on key areas such as segregated development environments, software bill of materials (SBOM), and vulnerability disclosure programs, aligning with international initiatives from the UK, EU, and US.

🛠️ Technical Deep Dive

Secure by Design & Secure by Default: Software should be inherently secure without extensive post-installation configuration. This includes built-in security measures like multi-factor authentication and event logging at no extra cost.
Developer Skill Vetting: Control ISM-2121 mandates that software developers possess adequate cybersecurity knowledge and skills for their tasks, with a companion control suggesting training and recording of these skills.
Environment Segregation: Development, testing, staging, and production environments, along with their associated data, must be segregated to prevent the spread of malicious or faulty code.
Authoritative Source for Software: A secure and authoritative source for software artifacts must be established and maintained, with robust access controls and event logging to prevent unauthorized access or modification.
Memory-Safe Languages & Practices: The ISM advocates for the use of memory-safe programming languages (e.g., C#, Go, Java, Ruby, Rust, Swift) or, less preferably, memory-safe programming practices to reduce common security risks.
Threat Modeling: Threat modeling is a required practice throughout the software development lifecycle, with reviews to reflect as-built software and evolving threat environments.
Software Security Testing: Comprehensive testing should be repeatable and scalable, including peer reviews, code reviews, unit testing, integration testing, SAST, DAST, and SCA.
Digital Signatures & Cryptographic Checksums: Installers, patches, and updates must be digitally signed or provided with cryptographic checksums to verify authenticity and integrity.
Software Bill of Materials (SBOM): Production and availability of SBOMs are recommended to enhance cyber supply chain transparency and facilitate risk management of software components.
Vulnerability Disclosure Programs: Implementation of vulnerability disclosure programs based on responsible disclosure is encouraged to improve product security.
AI Application Development: Specific controls apply to AI applications, including designing them to reduce attack surface, storing AI models in non-executable formats, and mitigating OWASP Top 10 for LLM applications.

🔮 Future ImplicationsAI analysis grounded in cited sources

Australian government software will see a significant uplift in baseline security.

The mandatory alignment with revised ISM standards for government-facing software will compel agencies and contractors to adopt more rigorous secure coding practices and developer skill verification, leading to more resilient systems.

There will be increased demand for cybersecurity training and certification for software developers in Australia.

The ISM's new controls explicitly requiring developers to possess sufficient cybersecurity skills and recommending training will drive organizations to invest in upskilling their development teams.

The adoption of 'Secure by Design' and 'Secure by Default' principles will become a de facto industry standard for Australian software development.

As the ISM is a benchmark for government and increasingly private sector organizations, these principles will permeate broader industry practices to ensure compliance and enhance trust.
