Nov 1, 2023 • 1 min read

Client Overview

Our client is a major Federal Government department which operates one of the largest and most complex ICT networks in Australia. Operating across multiple security domains, the client maintains over 134,000 workstations, 8,400 servers and 3,000 applications in support of over 133,000 users. This network is critical to the operations and business elements of the department.

Client’s Challenge

The primary challenge facing our client’s ICT network is the extensive volume of information, data and access points that must be safeguarded against insider threats. With a network and workforce of such magnitude, the potential for insider threats is significant. This multifaceted challenge encompasses:

  • Diverse Attack Vectors: Insider threats can manifest in various forms, including unauthorised data access, credential misuse and attempts to bypass security protocols. The complexity of the network amplifies this challenge.
  • Data Sensitivity: The client network handles highly sensitive data, making its protection paramount.
  • Network Complexity: Our client operates multiple networks, adding to the complexity of monitoring and securing each component effectively.
  • Human Elements: Balancing security with usability is complex, as insider threats can be malicious, negligent, and unintentional.
  • Policy and Legislation: Rapid adoption of new technologies, and the evolving threat landscape can expose legislative and regulatory documents that govern security controls to emerging threats.
  • Timely Detection: Swiftly identifying insider threats within the vast volume of data is vital to prevent disruptions and breaches.
  • Resource Constraints: Despite a substantial workforce, allocating resources effectively to address insider threats is demanding.

In the realm of compliance management, we have meticulously overseen the network's adherence to rigorous regulatory standards, preserving data integrity and operational compliance.

Tailored security policies have been developed in collaboration with the client to instill a culture of security consciousness and compliance among the workforces. This strategic emphasis on behaviour and policy is pivotal in creating a comprehensive security shield.

Real-time threat intelligence has empowered the client’s ICT network to remain vigilant in the face of evolving threats. This up-to-the-minute awareness is pivotal in ensuring preparedness and response.

The security architecture of the network has been redesigned, adding multiple layers of protection to shield against breaches and vulnerabilities. Identity and access management have been bolstered, ensuring that only authorised personnel can access sensitive data and resources. Our expert consultants have also provided ongoing guidance, supporting network security measures at all levels.
