Defence Industry Security Program (DISP)

Cyber Security Standards for Australian Defence Contractors

Organisations that want to work with the Australian Defence Force (ADF) or the broader Department of Defence supply chain need to understand the security standards expected of them. In most cases, the key framework is the Defence Industry Security Program (DISP), which helps Australian businesses meet Defence security obligations when engaging in tenders, contracts, and projects. Defence states that DISP supports entities to understand and meet their security obligations when working with Defence.

What Is DISP?

The Defence Industry Security Program (DISP) is the Australian Government’s primary security framework for organisations working with the Department of Defence. It ensures contractors implement strong safeguards when handling sensitive information and systems, reducing cyber risk across the Defence supply chain.

DISP is built around four key security areas:

  • Governance – Policies, risk management, and security oversight
  • Personnel security – Staff vetting and ongoing suitability checks
  • Physical security – Protection of facilities, assets, and equipment
  • ICT & cyber security – Securing systems, networks, and data

For businesses seeking Defence work, DISP membership is often mandatory. It demonstrates that your organisation has the appropriate controls, processes, and compliance measures in place.

Importantly, companies must align with standards such as the ASD Essential Eight, ensuring a strong cyber security posture. Achieving DISP strengthens your organisation’s credibility, resilience, and eligibility for Defence contracts.

The Core Cyber Security Standard: ASD Essential Eight

The ASD Essential Eight is the core cyber security standard used within the Defence Industry Security Program (DISP) and is widely recognised as Australia’s baseline for protecting business systems. Developed by the Australian Signals Directorate, it focuses on reducing the risk of cyber attacks through practical, high-impact controls.

The Essential Eight includes:

  • Application control to prevent unauthorised software execution
  • Patch applications to fix known vulnerabilities quickly
  • Microsoft Office macro controls to block malicious scripts
  • User application hardening to reduce attack surfaces
  • Restrict administrative privileges to limit access risks
  • Patch operating systems to maintain system security
  • Multi-factor authentication (MFA) to protect user accounts
  • Regular backups to enable recovery from incidents

These strategies are specifically designed to defend against common threats such as ransomware, phishing, and credential compromise, making them essential for organisations working with Defence or handling sensitive data.

Required Maturity Level for Defence Contractors

To meet Defence Industry Security Program (DISP) requirements, organisations are typically required to achieve Essential Eight Maturity Level 2 (ML2), a key benchmark in modern cybersecurity frameworks. This level ensures that security controls are fully implemented, consistently applied, and actively managed across all systems. Achieving ML2 demonstrates a strong commitment to protecting sensitive defence data and aligning with Australian Government security expectations.

At this maturity level, organisations focus on:

  • Consistent application of security controls across all devices and users
  • Active system monitoring and maintenance to detect and respond to threats
  • Structured risk management processes to identify and mitigate vulnerabilities
  • Embedding cybersecurity into daily operations and staff workflows

Reaching Essential Eight ML2 is not a “set and forget” approach. Instead, it requires continuous improvement, regular reviews, and ongoing optimisation of security measures. This ensures organisations remain resilient against evolving cyber threats while maintaining compliance.

Implementing ML2 also supports improved visibility, stronger endpoint protection, and better incident response, making it a critical step for any business working with defence contracts.

Ongoing Cyber Security & Assurance Requirements

Ongoing Cyber Security & Assurance Requirements are a critical part of maintaining DISP compliance and ensuring organisations remain protected against evolving threats. Unlike one-time implementations, DISP requires continuous validation, reporting, and improvement of cybersecurity controls. Businesses must demonstrate that their security posture is actively managed, documented, and regularly reviewed to meet Australian defence standards.

To maintain compliance, organisations should:

  • Complete the Essential Eight Cyber Security Questionnaire (CSQ) annually to validate maturity levels
  • Maintain up-to-date policies and procedures aligned with security frameworks
  • Provide clear evidence of implemented security controls across systems and users
  • Regularly review and test security measures to identify gaps and improve resilience
  • Manage third-party and supplier risks to prevent external vulnerabilities

These ongoing requirements ensure that cybersecurity is not static but continuously evolving and improving. By embedding these practices into daily operations, organisations can achieve long-term compliance, stronger risk management, and enhanced protection of sensitive defence-related data and systems.

Supporting Frameworks and Standards

Supporting Frameworks and Standards play a vital role in strengthening DISP compliance and enhancing an organisation’s overall cybersecurity posture. In addition to the Essential Eight, businesses working with Defence may be required to align with additional frameworks depending on the sensitivity and scope of their work. These frameworks provide structured guidance, governance models, and security controls to ensure systems and data are adequately protected.

Key frameworks include:

  • Information Security Manual (ISM) – A comprehensive cybersecurity framework developed by the Australian Government, offering detailed security controls and best practices for protecting systems, networks, and sensitive data in high-security environments.
  • Defence Security Principles Framework (DSPF) – A broader Defence framework that outlines core security principles, including governance, personnel security, physical security, and risk management requirements.

By aligning with these frameworks, organisations can ensure they meet Defence security expectations, improve risk management, and maintain a consistent, auditable approach to cybersecurity across all operations.

Why This Matters for Defence Suppliers

Why This Matters for Defence Suppliers is a critical consideration for any organisation working within the Defence sector. Due to the sensitive nature of Defence projects, contractors are frequently targeted by cyber threats, making strong cybersecurity practices essential. Aligning with DISP requirements and the Essential Eight enables organisations to protect their systems, data, and reputation while meeting strict government expectations.

By adopting these standards, organisations can:

  • Qualify for Defence contracts and tenders, opening new business opportunities
  • Protect sensitive Defence and client data from unauthorised access
  • Reduce the risk of cyber incidents and data breaches through proactive controls
  • Improve governance, compliance, and audit readiness across the organisation
  • Build trust with Defence agencies and prime contractors

Implementing these frameworks is not just about compliance—it delivers long-term business value, strengthens security maturity, and positions organisations as trusted, reliable partners in the Defence supply chain while supporting ongoing growth and operational resilience.

How Your Business Can Prepare

How Your Business Can Prepare for DISP compliance starts with a structured and proactive approach to cybersecurity. Achieving alignment with the Essential Eight Maturity Level 2 (ML2) requires organisations to assess their current environment, identify gaps, and implement practical security improvements. Early planning is critical, as uplift activities can take time depending on existing systems and processes.

To prepare effectively, organisations should:

  • Conduct a gap assessment against Essential Eight ML2 to identify weaknesses and prioritise actions
  • Strengthen identity and access controls, including MFA and Conditional Access policies
  • Implement endpoint security solutions such as Microsoft Intune and Microsoft Defender
  • Improve patching and vulnerability management to reduce exposure to threats
  • Establish secure backup and recovery processes to ensure business continuity
  • Develop clear policies, documentation, and staff awareness training

By following these steps, businesses can build a strong cybersecurity foundation, improve compliance readiness, and ensure they are well-positioned to meet Defence security requirements while protecting critical systems and data.
