TXA Australia
Formed in 1999, TXA is a joint venture company owned by Australia’s three commercial metropolitan television networks, Seven, Nine and Ten. As 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 Government is implementing stronger legislation to help manage cybersecurity accountability. In line with these changes, TXA has a board driven initiative to develop a cybersecurity strategy for the organisation and gain a better understanding of their digital risk profile. TXA recognises the significant financial, operational and reputational damage a cyber-attack can result in.
"With the increasing convergence of our Operational Technology and IT networks the need for a more intelligent and capable cybersecurity 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 across cybersecurity and risk management, the GHD Digital Cybersecurity Team worked closely with TXA to complete a vulnerability assessment and conduct a mapping program of their entire network.
TXA's 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 an early assessment of the TXA's areas of risk, the NIST Cybersecurity Framework 1.1 was identified as an appropriate solution to manage and measure this risk, now and into the future.
As part of the overall solution, 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 Digital Cybersecurity 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 Digital 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.

The Benefits
Following the implementation of the suggested solution, TXA gained a number of benefits, including:
- A tailored cybersecurity 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
