A common starting point for organisations that want to improve data security is to ask: what security tools do we need? A better starting point is to ask: what data do we hold, how sensitive is it, and who should have access to it?
Without that foundation, security investment is difficult to direct. Tools are applied broadly rather than where risk is highest. Access controls are set by convenience rather than by need. And the organisation may be spending on controls that protect low-value data while gaps remain in the systems that matter most.
Microsolve helps clients build data security from the ground up starting with visibility, then classification, then controls proportionate to the sensitivity and value of each data type.
Effective data security is layered. No single control is sufficient. The layers work together to reduce the likelihood of an incident, limit the damage if one occurs, and enable the organisation to detect and respond quickly.
Before controls can be applied, the data landscape must be understood.
What data does the organisation hold?
Where does it sit on servers, in Microsoft 365, in cloud applications, on endpoints?
How sensitive is it?
Who can access it?
Classification creates the basis for proportionate, targeted controls.
Users should only have access to the data they need to do their job. Broad, unconstrained access is a significant risk multiplier. It means that a compromised account, a malicious insider, or a social engineering attack has access to far more data than necessary. Microsolve reviews and implements access controls that align with least-privilege principles across on-premise and cloud environments.
Sensitive data should be encrypted both in transit as it moves between systems and users, as well as at rest where it is stored on servers, endpoints, and cloud platforms. Encryption does not prevent all attacks, but it significantly limits the value of data to an attacker who obtains it without the keys to read it.
Access to sensitive data should be logged and monitored. Unusual patterns — a user accessing a large volume of files outside working hours, a new connection from an unfamiliar location, attempts to access restricted areas — are indicators worth investigating. Monitoring turns security from a one-time configuration task into an ongoing, active discipline.
Data does not only sit on servers. It moves to endpoints - laptops, workstations, mobile devices - where it may be stored, transmitted, or shared outside managed channels. Endpoint controls ensure that sensitive data is handled appropriately as it moves through the organisation.
Security vulnerabilities in operating systems, applications, and services create pathways for attackers to access data. Regular patching, vulnerability scanning, and configuration hardening reduce the attack surface and prevent common exploitation techniques.
Not all data security needs are equal. Organisations that hold personal information, health records, financial data, or information subject to specific regulatory frameworks carry obligations that go beyond general good practice.
In Australia, the Privacy Act 1988 and the Australian Privacy Principles set out requirements for how personal information must be handled, stored, and protected. The Notifiable Data Breaches scheme requires organisations to notify the Office of the Australian Information Commissioner and affected individuals when a breach is likely to result in serious harm.
Beyond privacy legislation, frameworks including the ASD Essential Eight, ISO 27001, and industry-specific requirements define standards that many organisations are expected to meet or align with.
Microsolve works with clients to understand their specific obligations and design data security controls that are proportionate, documented, and defensible, not just technically adequate.
Microsolve delivers data security as a managed, ongoing service, not a one-off assessment or a product sale. Our approach covers the full lifecycle of data security from initial assessment through to implementation, monitoring, and regular review.
Reviews current data landscape, access controls, permissions, and exposure against risk profile.
Defines sensitivity categories and maps existing data accordingly.
Designs least-privilege access across on-premise and cloud environments including Microsoft 365 and Azure AD / Entra ID.
Deploys at-rest and in-transit encryption for sensitive data across servers, endpoints, and cloud storage.
Configures Data Loss Prevention (DLP) policies, sensitivity labels, information barriers, and external sharing controls.
Provides continuous monitoring of data access, sharing activity, and security events with alerting for anomalies.
Delivers regular patching and vulnerability scanning to maintain hardened infrastructure.
Conducts periodic reviews of data security environment against current threats and evolving business requirements.
Offers expert support for data security incidents, including containment, recovery, and breach notification guidance.
Ransomware does not create vulnerabilities, it exploits them. The most common pathways are credential compromise, phishing, and unpatched systems. Once inside, ransomware seeks out the data that matters most to the organisation and makes it inaccessible unless a ransom is paid.
Preventing ransomware and recovering from it both depend on strong data security practices: access controls that limit how far an attack can spread, monitoring that detects unusual activity early, immutable backups that provide a clean recovery path, and incident response plans that are tested before they are needed.
Data security and backup are not separate disciplines. They are complementary layers of the same operational resilience posture.
Data security refers to the combination of controls such as technical, administrative, and policy-based, that protect business data from unauthorised access, modification, loss, or exposure. It includes access controls, encryption, monitoring, patch management, and incident response.
Start with visibility. Understand what data you hold, where it sits, how sensitive it is, and who can access it. That assessment gives the basis for proportionate, targeted controls rather than applying tools broadly and hoping for the best.
The most common sources of data loss and exposure are ransomware and malware, phishing and credential compromise, insider threat (accidental or malicious), misconfigured cloud services, and lost or unprotected endpoint devices.
The Privacy Act 1988 and the Australian Privacy Principles require organisations that handle personal information to protect it from misuse, loss, and unauthorised access. The Notifiable Data Breaches scheme requires organisations to notify affected individuals and the OAIC when a breach is likely to cause serious harm. Appropriate data security controls are integral to meeting these obligations.
Least-privilege access means users are only granted access to the data and systems they need to perform their role and nothing more. Limiting access reduces the potential damage from compromised accounts, malicious insiders, or social engineering attacks.
Microsoft 365 contains a significant volume of sensitive business data — email, documents, contacts, communications. Proper data security in a Microsoft 365 environment includes DLP policies, sensitivity labels, access controls, audit logging, and external sharing restrictions. Microsolve manages these configurations as part of a broader data security service.
A data security assessment gives you a clear, practical view of where your organisation's data sits, who can access it, and where the meaningful risks are. It is the starting point for proportionate, manageable protection.
