Introduction: Hybrid Work and the Australian Risk Landscape

The digital landscape for businesses in Australia is undergoing a significant transformation, particularly with the rise of hybrid and remote work. This shift has increased the reliance on cloud applications, Software-as-a-Service (SaaS) platforms, and remote connectivity, expanding the corporate attack surface like never before. As businesses embrace this new reality, understanding the essential connection strategies to safeguard their operations has never been more crucial.

The recent trends in cybersecurity indicate that ransomware attacks and data breaches frequently initiate through compromised remote access, stolen credentials, or employees unwittingly visiting malicious websites. According to a report from Australian Cyber Security Centre (ACSC), small to mid-sized businesses are particularly vulnerable, operating with flat networks that use broad Virtual Private Network (VPN) access and often lack adequate segmentation (ACSC, 2021).

The Importance of Zero Trust and SASE

To tackle these challenges effectively, adopting frameworks such as Zero Trust (“never trust, always verify”) and Secure Access Service Edge (SASE) is imperative. Zero Trust principles enforce least-privilege access based on user identity, device security, and contextual factors (Forrester, 2022). Meanwhile, SASE represents a cloud-delivered architecture that converges network and security services, bringing solutions like Zero Trust Network Access (ZTNA), secure web gateways, and advanced threat prevention closer to the users.

Harmony SASE is Check Point’s state-of-the-art platform that encapsulates these concepts, providing unified security across corporate networks and remote environments. It serves to enhance secure private application access, internet access protection, device posture enforcement, and advanced threat prevention services to Australian businesses.

Section 1: How Are You Connecting Remote Users to Corporate Resources?

The Business Language

It is critical to understand how remote users gain access to corporate resources. A prevalent reliance on traditional VPNs grants users broad network access once authenticated, opening up vast attack surfaces. If compromised, attackers can exploit this access to move laterally across your network and sensitive data.

Why This Matters

• Traditional VPNs provide IP-based access to entire subnets, leading to increased vulnerabilities (Cybersecurity & Infrastructure Security Agency, 2022).
• Lateral movement of data and privilege misuse are common tactics in cyberattacks, with industry guidance advocating for application-level segmentation instead (ACSC).
• Compromised remote access can trigger notifiable data breach obligations in regulated sectors such as financial services and healthcare, making proper access management crucial (Australian Privacy Act, 1988).

How Harmony SASE Helps

Harmony SASE employs Zero Trust Network Access (ZTNA) to enhance security protocols by limiting access to only expressly authorised applications, switching from legacy VPN access to tightly controlled, application-level permissions. Instead of providing a tunnel into the entire network, ZTNA ensures that users access only the applications they require to conduct their duties.

Section 2: How Are You Limiting User Access Only to the Applications They Need?

The Business Language

Implementing access controls is vital to minimizing potential risk exposure. Limiting users to only the applications necessary for their role is a fundamental principle of effective cybersecurity, often referred to as the Principle of Least Privilege (PoLP).

Why This Matters

• Users today often gain valid credentials through phishing or password reuse, which can lead to extensive damage. Limiting access diminishes the potential for lateral movement across your networks (Proofpoint, 2021).
• Over-privileged accounts are consistently identified as major risks during incident investigations, making PoLP essential in incident and ransomware case studies (CyberEdge Group, 2022).
• By ensuring users only access specific applications, businesses can significantly reduce exposure to potential threats.

How Harmony SASE Helps

Harmony SASE implements least-privilege access at the application level, allowing policies that define which specific users or groups can interact with particular corporate applications. This targeted access presents a strong line of defence against account compromise, ensuring that, for example, if a single user is phished, it acts as a speed bump rather than a highway into the organisational environment.

Section 3: How Do You Ensure Employees’ Device Security?

The Business Language

Ensuring that employees’ devices are secure is no longer a “nice to have” but a “must-have” for protecting corporate data and resources.

Why This Matters

• Compromised endpoints remain a leading infection vector for malware and credential theft. Cybercriminals often exploit these vulnerabilities once devices are connected to the corporate network (Verizon, 2022).
• Effective endpoint security must include elements such as full disk encryption, up-to-date operating systems, and active endpoint protection tools (IBM Security, 2021).
• Remote users often connect to corporate resources via personal Wi-Fi networks, increasing risks compared to controlled office environments (ACSC).

How Harmony SASE Helps

Harmony SASE integrates Device Posture Check (DPC) capabilities, which ensure that only compliant devices can access corporate resources. This includes checks on disk encryption status, active security software, OS version updates, and defined custom posture attributes. By implementing a “no compliant device, no access” policy, businesses can enforce stricter security measures that align seamlessly with Zero Trust principles.

Section 4: How Do You Connect Unmanaged Devices and Contractors to Company Resources?

The Business Language

Connecting unmanaged devices and third-party contractors to company resources poses significant security risks that need to be addressed strategically.

Why This Matters

• Many businesses require access from contractors and partners who often utilize unmanaged devices, presenting a challenging security landscape (Cyber Risk Management, 2022).
• Relying on a traditional VPN for these users has historically been deemed high-risk, as it not only grants broader access but can also expose sensitive data to the internet.
• Third-party access remains a known source of security incidents and supply chain compromises, frequently occurring due to accounts and devices operating outside primary security controls (McKinsey, 2021).

How Harmony SASE Helps

With Harmony SASE, businesses can eliminate the need for VPN access while offering agentless (clientless) ZTNA for unmanaged devices. This secure web portal allows contractors to access specific corporate resources without jeopardizing security. By adhering to Zero Trust policies, users only see and access applications explicitly published for their use, thus enforcing stringent controls and safeguarding corporate resources.

Section 5: How Are You Limiting Employee Access to Malicious Websites?

The Business Language

Another crucial aspect of cybersecurity is the ability to limit employee access to potentially harmful websites that may lead to serious breaches.

Why This Matters

• Employees often encounter phishing sites, malicious advertisements, and compromised legitimate sites that threaten to steal credentials or deploy malware (Webroot, 2021).
• Web traffic without filtering can provide a pathway into corporate networks, as phished users unknowingly reach malicious domains (Cisco, 2022).
• Smaller organisations are particularly susceptible; even one successful attack can cause substantial recovery time and costs, making proactive web threat management essential.

How Harmony SASE Helps

Harmony SASE encompasses secure web gateways and web filtering features designed to monitor and control web traffic. It inspects all requests, categorising and blocking access to known malicious sites in real time. Importantly, this protection extends whether employees are working in the office, from home, or on the move, ensuring robust cybersecurity without hindering user experience.

Section 6: How Are You Protecting Users from Downloading Malware?

The Business Language

Downloading files from the internet is an everyday activity for most employees, but this habit carries significant risks.

Why This Matters

• Downloads via emails, SaaS platforms, and websites can introduce malware, keyloggers, or other malicious content, which can cripple organisational security (Fortinet, 2021).
• Once malware is present on a device, it may encrypt files, steal credentials, or move laterally within the network, posing severe operational risks (Cybersecurity & Infrastructure Security Agency, 2022).
• Preventing malware during the download process constitutes a much more effective and economical approach than dealing with post-incident recovery and associated costs.

How Harmony SASE Helps

Harmony SASE provides targeted malware protection, scanning downloaded files for malicious content before they reach the endpoint. This proactive approach enables businesses to thwart potential threats before they infiltrate the network. In this way, the security team gains visibility across all download activities, allowing for timely responses to any suspicious behaviour while ensuring a safer user experience.
