Security governance is the backbone of the Defence Industry Security Program (DISP). While policies, systems, and physical controls are important, DISP assessments consistently focus on how security is governed, not just what controls exist.
Many organisations underestimate this area, assuming governance is implicit or can be satisfied through documentation alone. In reality, DISP expects security to be actively owned, overseen, and embedded into organisational decision-making.
This article explains what security governance means under DISP, how Defence expects it to operate, and why governance is critical to maintaining membership over time.
What security governance means under DISP
Security governance under DISP refers to the formal structures, roles, responsibilities, and oversight mechanisms used to manage security risk on an ongoing basis.
It is not limited to a single document or policy. Instead, it addresses:
- Who is accountable for security
- How security decisions are made
- How risks and incidents are escalated
- How changes are assessed and approved
- How compliance is reviewed and maintained
Effective governance ensures that security arrangements remain aligned with business operations as they evolve.
Why Defence places strong emphasis on governance
Defence recognises that most security failures occur during change, not during steady-state operations.
Organisations change constantly. Personnel move roles, systems are upgraded, contracts expand, and facilities change. Without clear governance, these changes can introduce unmanaged security risk.
DISP uses governance as a primary indicator of whether an organisation can manage security over time, not just at the point of accreditation.
Accountability for security under DISP
A core expectation under DISP is that security accountability is clearly defined and documented.
Defence requires organisations to formally appoint:
- a Security Officer (SO), responsible for day-to-day security management and coordination, and
- a Chief Security Officer (CSO), responsible for senior oversight, endorsement, and accountability for security matters.
These roles are central to governance under DISP. Defence expects them to be clearly assigned, understood by the organisation, and supported by appropriate authority.
Accountability must be explicit. It cannot be assumed or shared informally.
The role of senior leadership
While the SO manages operational security activities, DISP governance requires active involvement from senior leadership, particularly through the CSO role.
Senior leaders are expected to:
- Endorse security policies and frameworks
- Support security-related decisions
- Ensure adequate resources are allocated
- Maintain awareness of security risks affecting the organisation
Where security governance is isolated from leadership, Defence confidence is reduced.
Defining and documenting security roles
Clear definition of security roles is a recurring focus during DISP assessments.
Defence looks for evidence that:
- SO and CSO responsibilities are documented
- Authority and escalation paths are defined
- Responsibilities are realistic and achievable
- Back-up arrangements exist if role holders change
In smaller organisations, security roles may be combined with other duties. This is acceptable provided responsibilities remain clear and manageable.
Governance across the DISP security domains
Security governance must extend across all DISP domains, including:
- Personnel security
- Physical security
- Information and cyber security
- Security awareness and training
Governance arrangements should provide oversight across these areas rather than treating them as separate silos. Fragmented governance often leads to gaps, particularly when changes occur.
Policies as governance mechanisms
Under DISP, policies support governance only when they are actively used.
Defence expects policies to:
- Reflect real practices
- Be approved by the appropriate authority
- Be communicated to relevant personnel
- Be reviewed periodically
Policies that exist solely for accreditation purposes, without operational ownership, undermine governance credibility.
Governance and security risk management
DISP governance is closely linked to risk management.
Organisations are expected to:
- Identify security risks
- Assess their impact and likelihood
- Implement appropriate controls
- Review risk as conditions change
DISP does not require risk elimination, but it does require informed and documented decision-making.
Managing organisational change
Governance plays a critical role in managing change under DISP.
Changes that typically require security review include:
- New Defence contracts or expanded scope
- Changes in information classification
- System upgrades or migrations
- Facility relocations or access changes
- Changes to key or relevant personnel
Where governance is weak, changes may occur without security consideration, creating compliance risk.
Ongoing compliance and “maintaining membership”
Security governance under DISP extends beyond accreditation and into maintaining membership.
Organisations are required to:
- Submit an Annual Security Report each year
- Report changes in circumstance when they occur
- Maintain required registers (such as incidents and other security-related records)
- Ensure personnel security arrangements remain current
- Oversee ongoing compliance across all security domains
These activities sit squarely within governance responsibilities and are typically coordinated by the SO, with review and endorsement by the CSO.
Oversight, review, and assurance
Defence expects organisations to demonstrate that governance mechanisms are active.
This may include:
- Periodic internal security reviews
- Management reporting on security matters
- Tracking and remediation of issues
- Preparation for annual reporting
Oversight provides evidence that security is being managed deliberately rather than assumed.
Common governance weaknesses identified under DISP
Governance issues often arise where:
- SO or CSO roles are unclear or unsupported
- Accountability exists on paper only
- Senior leadership is disengaged
- Changes are implemented without security review
- Governance responsibilities are delegated without authority
These weaknesses frequently lead to broader compliance issues over time.
Governance in organisations of different sizes
DISP governance expectations apply regardless of organisation size.
Small organisations may use simpler governance structures, while larger organisations require more formal mechanisms to manage complexity. In all cases, Defence assesses appropriateness, not bureaucracy.
Governance as an enabler
Strong security governance supports operational effectiveness.
When roles are clear and oversight is structured:
- Security issues are identified earlier
- Decisions are made with confidence
- Compliance is easier to maintain
- Change is managed without disruption
Governance should enable secure operations, not obstruct them.
Final thoughts
Security governance is central to DISP because it underpins every other security control.
Policies, systems, and procedures can all fail if governance is weak. Conversely, strong governance allows organisations to adapt and grow while maintaining Defence confidence.
For DISP members, effective governance is not simply a compliance requirement. It is a capability that sustains trust, resilience, and long-term participation in the Defence supply chain.
Most organisations entering the Defence supply chain underestimate what DISP actually requires or assume existing policies are enough.
