SOC 2 access reviews for internal apps: a quarterly process

What problem access reviews actually solve

An access review is a quick, written check that answers one question: does each person still need the access they currently have? It’s not a technical deep dive. It’s a practical habit that keeps internal apps from slowly turning into “everyone can do everything.”

The main issue access reviews prevent is privilege creep. That’s when people collect extra permissions over time and never give them back. A support agent gets refund access to help during a busy month. Two quarters later they’ve moved teams, but the refund permission is still there because no one remembered to remove it.

Access reviews mainly fix three everyday problems: old access that lingers after role changes, “temporary” admin access that becomes permanent, and the uncomfortable moment when someone asks who can do what and nobody can answer with confidence.

The goal isn’t to catch bad people. It’s to confirm that good intent still matches current reality: current job, current team, current risk.

Set expectations early: keep it lightweight and recurring. A quarterly review should feel like routine maintenance, not a one-time cleanup that takes weeks. Small, consistent corrections beat a big “access reset” that everyone avoids until an audit forces it.

Where internal app access usually goes wrong

Internal apps usually start simple. A few people need to get work done quickly, so access is granted fast and rarely revisited. Over months, the app gains features, more teams touch it, and permissions quietly pile up.

The biggest offenders are everyday tools that feel “safe” because they aren’t customer-facing: ops admin panels, support tools (ticketing, refunds, account lookups), BI dashboards, CRM systems, and HR tools like payroll or hiring pipelines.

As these tools grow, access often expands in the easiest possible way: copy a coworker’s permissions, add a quick exception, or grant an admin role so someone can unblock themselves. Months later, nobody remembers why those permissions were added, but they still exist.

A few risk areas show up again and again because the impact is immediate:

• Data exports (CSV downloads, bulk exports)
• Payments and refunds (Stripe actions, credits, chargebacks)
• User management (create users, reset passwords, assign roles)
• Configuration changes (feature flags, pricing rules, integrations)
• Broad record access (sensitive fields across all accounts)

One common gap: teams review app permissions but forget infrastructure access. App roles control what someone can do inside the tool. Infrastructure access covers the database, cloud console, logs, and deployment pipelines. Someone can be “read-only” in the app and still have powerful access through underlying systems if you don’t track both.

A lightweight quarterly review, in one page

A quarterly access review only works if it’s easy to finish. The goal is simple: confirm who still needs access to each internal app, then remove anything that’s no longer needed before it turns into privilege creep.

Pick a steady cadence (quarterly) and the smallest group that can make good decisions. In most teams, that’s an app owner (knows what the app does), a manager for each department (knows people and roles), and someone who can apply changes (IT or a platform admin).

Set a cutoff date and treat the review as an “as of” snapshot, for example: “Access list as of April 1.” Access changes every day. A snapshot keeps the review fair and stops endless re-checking.

For each user, you only need a clear decision: keep access as-is, remove access (or reduce it), or record an exception with a reason and an end date.

Evidence doesn’t need to be a long report. It just needs to be clear, consistent, and repeatable: the snapshot date, who reviewed, what changed, and why any exceptions exist.

One-page template you can reuse

A single table or spreadsheet is enough. Track the app, user, role or permission level, last login (optional), decision (keep/remove/exception), exception reason and expiry, reviewer, review date, and change applied date.

If you build internal tools on a platform like AppMaster, you can keep this evidence inside the same admin app: one screen for the snapshot, one for decisions, and one for exception reminders. It keeps the review close to the system it’s describing and makes it easier to repeat.

Simple permission design that makes reviews easier

If access reviews feel messy, it’s usually because permissions are messy. The goal isn’t perfect policy language. It’s a role setup that lets you answer one question quickly: “Should this person still be able to do this?”

Keep roles small and readable. Most internal apps can live with 5 to 20 roles. Once you have hundreds of one-off exceptions, every quarterly review becomes a debate instead of a check.

A practical approach is job-based roles with least privilege as the default. Give people what they need for daily work, and make anything extra a time-bound add-on that expires or gets re-approved.

A few role design rules make reviews easier:

• Prefer job roles (Support Agent, Ops Manager) over person-specific roles
• Separate “can view” from “can change” permissions
• Treat “can export” as its own permission
• Keep powerful actions rare (delete, refund, change billing, edit payroll)
• Document what each role is for in one plain sentence

It also helps to have one “break-glass” admin role for emergencies, wrapped in extra controls: approval, time limits, and detailed logging.

Example: in a support portal, “Support Viewer” can read tickets, “Support Editor” can update and reply, and “Support Exporter” can download reports. During the quarterly review, you can quickly spot that someone who moved teams still has Exporter and remove it without blocking day-to-day work.

A basic data model for tracking access and reviews

Access reviews get easier when you can answer three questions quickly: who has access, why they have it, and when it should end.

You can start in a spreadsheet, but a small database pays off once you have more than a few apps and teams. If you already build internal tools in AppMaster, this fits naturally in the Data Designer (PostgreSQL).

Here is a simple, practical schema to start with:

-- Core
Users(id, email, full_name, department, manager_id, status, created_at)
Apps(id, name, owner_user_id, status, created_at)
Roles(id, app_id, name, description, created_at)
Permissions(id, app_id, key, description)

-- Many-to-many, with audit-friendly fields
UserRoleAssignments(
  id, user_id, role_id,
  granted_by_user_id,
  reason,
  ticket_ref,
  created_at,
  expires_at
)

-- Optional: role to permission mapping (if you want explicit RBAC)
RolePermissions(id, role_id, permission_id)

-- Review history
AccessReviewRecords(
  id, app_id,
  reviewer_user_id,
  review_date,
  outcome,
  notes
)

-- Exception tracking: temporary elevation
AccessExceptions(
  id, user_id, app_id,
  permission_or_role,
  approved_by_user_id,
  reason,
  ticket_ref,
  created_at,
  expires_at
)

A few rules make this work in real life. Every assignment needs an owner (who approved it), a reason (plain language), and a ticket reference (so you can trace the request). Use expires_at aggressively for temporary access, on-call rotations, and incident support. If it’s hard to choose an expiry date, that’s often a sign the role is too broad.

Keep review outcomes simple so people actually record them: keep as-is, remove, downgrade, renew with a new expiry, or document as exception.

The review record table matters most. It proves the review happened, who did it, what changed, and why.

Step-by-step: how to run the quarterly access review

A quarterly review works best when it feels like routine admin work, not an audit event. The goal is straightforward: someone responsible looks at access, makes decisions, and you can show what changed.

1. Pull an access snapshot for each internal app. Export a point-in-time list of active users, their roles or permission groups, key privileges, last login, and who approved access originally (if you have it). If the app supports it, include service accounts and API keys.

2. Send each snapshot to one named app owner. Keep ownership clear: one person approves, others can comment. If there’s no obvious owner, assign one before you start. Add a due date and a rule: no response means access gets reduced to the safest default.

3. Highlight permissions that deserve extra attention. Don’t ask owners to read every row equally. Mark anything that can move money, export data, delete records, change permissions, or access customer data. Also flag users with no login activity since last quarter.

4. Apply changes quickly and record them as you go. Remove unused accounts, downgrade roles, and turn “temporary” access into time-boxed access with expiry dates. The review isn’t complete until changes are actually in the system.

5. Close the loop with a short write-up and saved evidence. One page is enough: what you reviewed, who approved, what changed, and what’s still open.

Save evidence that’s easy to show later:

• The exported snapshot (dated)
• Approval notes from each app owner
• A change log (adds, removals, downgrades)
• A short summary of outcomes
• Exceptions and their expiration dates

If your internal tools are built on a platform like AppMaster, you can make access owners and approval notes part of the workflow so evidence is created as work happens.

What to check first to catch privilege creep early

When you only have time for a few checks, focus where access quietly expands over time. These are also the items auditors ask about because they show whether your controls work in real life.

Start with fast, high-signal checks:

• Accounts that no longer match reality (former employees, ended contractors) but still have logins or API tokens
• Shared credentials where you can’t tell who did what
• Elevated access that was meant to be temporary but has no end date or review note
• People who changed roles but kept access from the old job (support to sales, but still has refunds or data export)
• Apps with no clear owner to approve access requests and review the user list

Then do a quick “why” check on anything that looks off. Ask for a ticket, request, or manager approval that explains the access. If you can’t find a reason in a few minutes, downgrade or remove it.

Example: a marketing analyst helps ops for two weeks and gets admin rights to an internal dashboard. Three months later, they still have admin, plus access to billing. A quarterly review should catch that by comparing current job role to current permissions.

Common mistakes that make reviews ineffective

The point of these reviews is simple: prove that someone checks access, understands why it exists, and removes what’s no longer needed. The fastest way to fail is to treat it as a box to tick.

Mistakes that quietly break the process

• Keeping the whole review in a shared spreadsheet where anyone can edit rows, no one clearly owns approvals, and sign-off is just “looks good.”
• Approving access without confirming the person still needs it for their current job, or without checking scope (read vs write, production vs staging).
• Only reviewing admins, while ignoring powerful non-admin roles like “Finance: payouts,” “Support: refunds,” or “Ops: data export.”
• Removing access in a meeting but not recording what was removed and when, so the same accounts reappear next quarter.
• Letting exceptions stay forever because there’s no expiry date and no one is prompted to re-justify them.

A common example: a support lead temporarily gets “Refunds” access during a busy month. Three months later, they’ve moved to sales, but the permission is still there because it was never tracked as a removal item and no one asked for a new reason.

Fixes that keep reviews honest

• Require a named reviewer and a dated sign-off, even if the tool is basic.
• For each high-impact permission, record a short reason tied to a job need.
• Review high-impact roles and workflows, not just the admin list.
• Track removals as their own outcome (who, what, when), then confirm they stayed removed.
• Put an expiry on exceptions by default, and require fresh approval to renew.

Quarterly checklist you can reuse each time

A good quarterly review is boring on purpose. You want the same steps every time and no guessing about who approved what.

• Take an access snapshot and label it. Export a current list of users and roles/permissions for each app, save it with an “as of” date (for example: SupportPortal_access_2026-01-01). If you can’t export, capture screenshots or a report and store it the same way.
• Confirm each app has a single named owner who decides. For every internal app, write down the owner and have them mark each user as keep, remove, or change role.
• Review high-risk permissions separately. Pull admins and export/download permissions into their own short list. That’s where privilege creep hides.
• Expire temporary access on purpose. Any “just for this project” access needs an expiry date. If there’s no expiry date, treat it as permanent and re-justify it or remove it.
• Complete removals and verify they worked. Don’t stop at “ticket created.” Confirm access is actually gone (re-run the snapshot or spot-check role screens) and note the verification date.

Store a simple review record for each app: reviewer name, date, outcome (no changes / changes made), and a short note on any exceptions.

A realistic example: one quarter at a small company

A 45-person company runs two internal apps: a Support tool (tickets, refunds, customer notes) and an Ops admin panel (orders, inventory, payout reports). The apps were built quickly in a no-code platform like AppMaster and kept growing as teams asked for “just one more screen.”

At the start of the quarter, access looked fine on paper. Ops, Support, and Finance each had their own roles. But the last quarter had a busy launch, and a few “temporary” changes never got rolled back.

One clear case of privilege creep: a Support lead needed admin access for one weekend to fix a batch of duplicated orders. The team granted the full “Ops Admin” role to avoid blocking the work. Three months later, that role was still there. During the review, the manager admitted the lead only needed two actions: view order history and trigger a resend of receipts.

The review meeting took 35 minutes. They went user by user, starting with the highest-privilege roles and any access that hadn’t been used lately:

• Keep: Ops managers kept full admin, since it matched daily work.
• Remove: one Finance contractor still had access to the Support tool.
• Downgrade: the Support lead moved from “Ops Admin” to a limited “Order Support” role.
• Temporary exception: a Finance analyst got elevated access for 14 days for quarterly reconciliation, with an owner and an end date.

They also cleaned up a shared admin account used for testing. Instead of letting everyone borrow it, they disabled it and created named accounts with the right roles.

What they saved after one quarter:

• 3 full admin roles removed
• 4 users downgraded to least-privilege roles
• 2 stale accounts disabled (one former employee, one contractor)
• 1 temporary exception created with an end date and owner

Nothing broke, and Support still got the two actions they needed. The win was reducing “just in case” access before it became normal.

Next steps: make the process repeatable

Pick a small starting point and keep it boring. The goal isn’t a perfect system. It’s a rhythm that runs every quarter without heroics.

Start with your top three internal apps: the ones that touch customer data, money, or admin actions. For each app, name a single owner who can answer, “Who should have access, and why?” Then write down a handful of roles that match how people actually work (Viewer, Agent, Manager, Admin).

Put the review on the calendar now with a clear window. A simple pattern is a recurring reminder on the first business day of the quarter and a two-week window so approvers aren’t rushed and leavers don’t linger.

Decide where the review record lives and who can change it. Whatever you choose, keep it consistent and controlled so you can point to one place when someone asks for evidence.

A setup that holds up over time:

• Assign an owner and backup owner for each internal app
• Keep a single access review log with edit rights limited to owners and security
• Require a one-sentence reason for each keep/remove/exception decision
• Track follow-up actions with due dates
• Do a quick sign-off at the end of the window (owner + manager)

If you’re already building internal tools on AppMaster (appmaster.io), you can embed this process directly into the apps you run: role-based access, approvals for elevated roles, and audit-friendly records that capture who changed what and why.

Once the same people do the same small steps every quarter, privilege creep becomes obvious and easy to fix.
