Cloud security and access control for firms
Moving to the cloud does not have to mean losing control of your data. How to secure cloud tools and get access control right.
Most accounting practices now run on cloud software, and for good reason: it removes the burden of maintaining servers and makes remote work practical. But moving to the cloud shifts, rather than removes, your security responsibilities. Getting access control right is where much of that responsibility lands.
The cloud shares responsibility
Reputable cloud providers invest heavily in securing their infrastructure, often more than a small firm ever could. What they cannot do is control how you configure access, who you invite in, and how carefully your team behaves. That part is yours. Understanding this shared-responsibility model is the foundation of cloud security.
- Provider secures the platform. Data centres, encryption, uptime.
- You secure access. Accounts, permissions and staff behaviour.
- Both matter. A secure platform with sloppy access is still exposed.
Get access control right
Access control is the discipline of ensuring people can reach only what their role requires, and nothing more. A junior preparer rarely needs the full client list or historic payroll data. Applying least privilege limits the damage if any single account is compromised.
Use role-based access
Rather than granting permissions one by one, define roles that match how your firm works and assign people to them. This keeps access consistent and makes it easy to adjust when someone changes role or leaves. Finye supports role-based access so you can control what each team member sees and does across the practice.
Protect the accounts themselves
Strong access control still fails if accounts are easy to break into. Require multi-factor authentication so a stolen password alone is not enough. The Australian Cyber Security Centre consistently ranks multi-factor authentication among the most effective controls a business can adopt.
Review access regularly
Access tends to accumulate. People change roles, projects end, and old permissions linger. Schedule a periodic review to remove access that is no longer needed and to promptly revoke it when someone leaves. Dormant accounts with live permissions are a favourite target for attackers.
Cloud tools can be more secure than the old on-premise setup they replaced, provided you take your share of the responsibility seriously. Sound access control, protected accounts and regular reviews cover most of the risk. For related guidance on protecting client information, see Finye's guides or read more on our blog.
