Home Affairs Probes Secure Service Edge for Improved Cybersecurity

Concise Overview

• The Department of Home Affairs is updating its security infrastructure using Secure Service Edge (SSE).
• The organization aims for a scalable and modern secure gateway to boost cybersecurity.
• Initial priorities include web proxy functionalities, cloud access security broker (CASB), and measures for data loss prevention.
• Future initiatives may encompass full CASB integration and zero trust network access.
• The existing gateway accommodates as many as 18,000 users and supports a variety of cloud-based applications.
• Home Affairs plans to shift towards a cloud-driven secure web gateway with an on-premises setup.
• This effort corresponds with the Resilient Digital Infrastructure (RDI) framework to enhance IT security.

Home Affairs Pursues Secure Service Edge for Enhanced Cybersecurity

Reasons Behind Home Affairs’ Adoption of Secure Service Edge

The Australian government is proactively addressing cybersecurity by exploring Secure Service Edge (SSE) options. The Department of Home Affairs has issued a tender request, indicating its plan to modernise perimeter security and move towards a more scalable and robust digital security framework.

Defining Secure Service Edge (SSE)

SSE represents a cloud-native security architecture that consolidates various cybersecurity functions, such as secure web gateways (SWG), cloud access security brokers (CASB), and Zero Trust Network Access (ZTNA). This framework enables organizations to safeguard users, applications, and data regardless of their geographical location, thus ensuring a flexible and expandable security landscape.

The Importance of a Secure Web Gateway

In the near term, Home Affairs is focusing on implementing a secure web gateway (SWG) as it adopts SSE. The SWG will deliver web filtering, protection against malware, and data loss prevention to strengthen online security. The department is striving to create a system that is resilient, scalable, and minimizes disruption to its ongoing operations.

Cloud-Based Deployment vs. On-Premises Solutions

Currently, Home Affairs uses an on-premises security gateway, but its future vision includes incorporating a cloud-based solution alongside an on-premises aspect. This hybrid strategy provides greater flexibility, allowing the agency to retain control over sensitive information while utilizing the benefits of cloud-based security, such as scalability and up-to-date threat intelligence.

Alignment with the Resilient Digital Infrastructure (RDI) Framework

The transition to SSE aligns with the wider Resilient Digital Infrastructure (RDI) framework, which aims to modernise IT security among federal government agencies. The RDI framework encourages the consolidation of IT infrastructure policies, focusing on secure internet gateways, email safety, and SSE technology to boost cybersecurity resilience across Australia.

Consequences for Cybersecurity in Australia

Home Affairs’ adoption of SSE sets a standard for other government entities and private organizations striving to strengthen their cybersecurity strategies. As cyber threats continue to advance, the implementation of modern security frameworks like SSE will help ensure the protection of Australian government systems against complex cyberattacks.

Conclusion

The Department of Home Affairs is making substantial progress in updating its security framework by examining Secure Service Edge (SSE) options. With an initial focus on web proxy functionalities and limited CASB features, the department intends to shift towards a cloud-driven secure web gateway. This initiative aligns with the Resilient Digital Infrastructure (RDI) framework, reaffirming Australia’s commitment to cybersecurity. By embracing SSE, Home Affairs is establishing a standard for other government bodies to enhance cyber resilience.

Common Questions

Q: What is Secure Service Edge (SSE)?

A:
