Downer Professional Services Negates Insider Cyber Threats to Secure, Assure and Defend ICT Networks
Nov 1, 2023 • 1 min read
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.
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.
