In today’s interconnected world, digital security has become a paramount concern, which nbn – the driving force behind lifting the digital capability of Australia – knows more than most.

In 2009, the Federal Government established NBN Co with a distinct purpose: to construct, develop and manage a nationwide wholesale broadband access network for Australia. The nbn network now provides digital connectivity to over 12 million premises around Australia, with the importance of cyber security rising sharply since 2009.

Australian companies encounter many cyber security challenges, encompassing conventional and emerging threats – anticipating the occurrence of data breaches or the precise timing of an impending threat is often a very complex task.

nbn has adopted an ‘all hazards or converged’ security model, which prioritises and aligns personnel, physical and cyber security to ensure fast and reliable connectivity and one that aims to create a safe and secure environment.

The last wall(s) of defence

nbn’s security model is based on a comprehensive understanding of security and follows the ‘three lines of defence’ principle to fortify its security measures:

  • Line one comprises the operations team responsible for implementing and maintaining the security ecosystem, ensuring the availability and effectiveness of tools, processes, and controls
  • Line two acts as an independent assessor and business partner of line one, identifying potential gaps, points of improvement or vulnerabilities, and then working with the line to continually improve our effectiveness
  • Line three provides independent assurance of lines one and two, providing appropriate governance, alignment and accountability
    are maintained

During interactions with property developers, nbn aims to focus not just on current connectivity solutions but also on future-ready technology, to help ensure it’s ready to meet the digital demands of tomorrow.

A vital part of the community

As nbn extends its connectivity services to new developments and, by proxy, becomes increasingly important to many community services, such as electronic signage and public Wi-Fi, nbn’s supply chain continues to play a vital role.

Like any property company, nbn faces the challenges of managing an extensive and complex supply chain. The supply chain’s crucial role in ensuring the security of nbn is maintained, and the ongoing focus the organisation places on working collaboratively with its partners, will ensure this happens.
