Cyber Mapping

TXA's Cyber Security and Risk Management Framework

HomeProjects

TX Australia 

Formed in 1999, TXA is a joint venture company owned by Australia’s three commercial metropolitan television networks, Seven, Nine and Ten. A critical infrastructure provider, TXA supplies the transmission of free to air television for these three networks.

The Challenge

With the continued challenge of data-security and cyber-crime, the Australian Federal Government are implementing stronger legislation to help manage cyber security accountability. In line with these changes, TXA has a Board driven initiative to develop a Cyber Security Strategy for the organisation and gain a better understanding of their own digital risk profile. TXA recognises the significant financial, operational and reputational damage a cyber-attack can result in. Subsequently, TXA engaged GHD Digital due to the specialised capabilities in cyber security and risk management for critical infrastructure organisations.

"With the increasing convergence of our OT (Operational Technology) and IT networks the need for a more intelligent and capable Cyber-Security strategy for the TXA is no longer a nice to have but an absolute requirement." 

- Michael Ryder, General Manager Technology & Engineering

The Solution

With in-depth knowledge and expertise across cyber security and risk management, the GHD cyber security team worked closely with TXA to complete a vulnerability assessment and conduct a mapping program of their entire network.

TXA management were looking to understand their entire risk posture and know where and when to invest to reduce their overall risk in the short, medium and longer terms. They were also looking for efficiencies from their current investments and processes. Following early assessment of the client’s areas of risk, the NIST Cybersecurity Framework 1.1 was identified by our team as the best solution to manage and measure this risk, now and into the future.

As part of the overall solution offered by GHD Digital, a full suite of corporate policies, department procedures and processes were developed, and various monitoring and technical controls to improve visibility and reduce risk were implemented. In addition, third party and supply chain risk assessments were conducted and the GHD cyber security team assisted in the development of third party supplier policies and visibility measures and controls.

"TXA’s Network has grown out of Telemetry requirements for our Broadcast Transmission infrastructure and is quite complex so in order to perform the most appropriate Security Gap Analysis we need specialists like the GHD Cybersecurity Team to step us through the process. By applying the NIST framework we were able to define an actionable roadmap to improve and build out the necessary policies, procedures and systems to get us where we needed to as an organisation." 

- Michael Ryder, General Manager Technology & Engineering

The Benefits 

Following the implementation of the suggested solution, TXA gained a number of benefits, including:

  • a tailored Cyber Security Strategy that clearly identifies their current risk posture and detailed plan for future maturity
  • efficient data handling and enhanced information sharing
  • complete visibility of all assets and risk profiles of each asset connected to their network
  • reduced risk from third party suppliers and contractors with clearly defined procedures, processes and accountability documentation

Combined, these benefits will help to identify and reduce business risk. Other benefits include the ability to comply with the Australian mandatory data breach scheme and if required GDPR, allowing for peace of mind for Directors, stakeholders and staff.
