1. The Challenge

A small to medium-sized healthcare organisation had recently experienced cyberattacks, raising concerns about the security of its IT environment and the protection of sensitive patient and business information.

The organisation relied on email, cloud applications, clinical systems, and network infrastructure to support its daily operations. Following the incidents, it became important to review the existing security controls, identify weaknesses, and reduce the risk of further compromise.

RemoteLink worked with the organisation to assess its IT security environment and identify areas requiring improvement. The review focused on user accounts, authentication, email security, endpoint protection, access permissions, network security, and backup arrangements.

The objective was to address the identified security risks while maintaining the availability of systems required for day-to-day healthcare operations.

​

2. The RemoteLink Approach

Cybersecurity Assessment and Risk Identification

RemoteLink reviewed the organisation's IT environment to identify security weaknesses and prioritise remediation activities.

The assessment covered:

• User accounts, multi-factor authentication (MFA), and administrator privileges.

• Microsoft 365 security settings, email protection, and suspicious account activity.

• Endpoint protection, system updates, and network security.

• Access to sensitive information and shared business data.

• Backup coverage and the ability to recover critical information.

• Existing security procedures and incident response arrangements.

The findings were used to establish priorities based on the potential impact and likelihood of security incidents. This helped focus attention on the areas requiring the most urgent attention.

Strengthening Identity and Access Security

User accounts and access permissions were reviewed to reduce the risk of unauthorised access.

RemoteLink addressed identified gaps in authentication and account security, including MFA coverage, privileged access, and unnecessary permissions, where applicable.

Microsoft 365 security settings were also reviewed to improve protection against account compromise and suspicious activity. Appropriate changes were made based on the organisation's existing configuration, licensing, and operational requirements.

These measures helped strengthen the controls protecting staff accounts and the information accessible through them.

Improving Email and Endpoint Protection

Email and endpoint security were reviewed because compromised accounts, phishing messages, and malicious software can provide attackers with opportunities to access business systems.

RemoteLink reviewed the available email security controls, endpoint protection, and system update arrangements. Identified weaknesses were prioritised for remediation.

The work focused on improving protection against phishing, malicious attachments, unauthorised access, and exploitation of known vulnerabilities.

Reviewing Data Protection and Recovery

RemoteLink reviewed the arrangements protecting the organisation's business information and critical data.

The review considered backup coverage, access permissions, administrative controls, and recovery requirements. Relevant improvements were identified and addressed according to priority.

Backup and recovery arrangements are particularly important for healthcare organisations because a cyber incident can affect both access to sensitive information and the continuity of business operations.

Improving Staff Awareness and Ongoing Security Management

Technical controls were supported by a focus on staff awareness and ongoing security management.

Staff guidance and security procedures were reviewed to help employees recognise suspicious emails, unexpected authentication requests, and potential security incidents.

RemoteLink also established or recommended ongoing review activities appropriate to the work completed, including security updates, access reviews, monitoring, and backup checks.

​

3. Outcomes and Business Benefits

The engagement gave the organisation a structured approach to identifying and addressing cybersecurity risks.

The work focused on strengthening security controls, improving visibility of potential weaknesses, and establishing clearer priorities for ongoing remediation.

The business benefits included:

• Improved security management: Security weaknesses were assessed and prioritised rather than addressed in isolation.

• Stronger access controls: Identified gaps in account security and permissions were addressed.

• Improved protection: Email, endpoint, and infrastructure security controls were reviewed and improved where required.

• Greater recovery preparedness: Backup and recovery arrangements received attention as part of the overall security review.

• Ongoing risk reduction: A more structured approach to security maintenance and remediation was established.

The effectiveness of these improvements should be assessed through ongoing monitoring, periodic reviews, and appropriate testing. No cybersecurity programme can eliminate all risk or guarantee that future attacks will be prevented.

​

4. Ongoing Cybersecurity

Cybersecurity is an ongoing responsibility rather than a one-off project. New vulnerabilities emerge, staff access changes, and attackers continue to develop new techniques.

Following the engagement, the organisation's ongoing security activities included, or were planned to include, appropriate monitoring, vulnerability management, access reviews, backup verification, and periodic reassessment of security risks.

The organisation's controls could also be reviewed against the Australian Cyber Security Centre's Essential Eight to help guide further improvements, based on its environment and risk profile.

​

Conclusion

The engagement demonstrated the importance of taking a structured, risk-based approach to cybersecurity following a cyber incident.

By reviewing the IT environment, prioritising weaknesses, and addressing security controls across accounts, email, endpoints, and data protection, RemoteLink helped establish a more systematic approach to managing the organisation's cybersecurity risks.

For small and medium-sized healthcare providers, a proactive approach to IT security helps protect sensitive information, support business continuity, and provide a clearer path towards ongoing security improvement.
