Security and Permissions

How ACL and CLP strategy secures users, projects, tasks, and status updates.

User profile security

Each user can only modify or delete their profile; unauthorized access is restricted.

Project and task integrity

Only project owners can create, update, or delete associated tasks. Validation through Cloud Code is recommended.

Scoped access permissions

Restrict project information and task visibility according to user roles to enforce security.

Build with AI Agent

Use the Back4app AI Agent to generate a fully functional Professional Service Automation platform from this template, encompassing frontend, backend, authentication, and project/task management flows.

Back4app AI Agent
Ready to build
Create a Professional Service Automation app backend on Back4app with this exact schema and behavior.

Schema:
1. User (use Back4app built-in): username, email, password; objectId, createdAt, updatedAt (system).
2. Project: name (String, required), description (String), status (String); objectId, createdAt, updatedAt (system).
3. Task: project (Pointer to Project, required), due date (Date), assigned user (Pointer to User); objectId, createdAt, updatedAt (system).
4. Status: project (Pointer to Project, required), update (String, required), timestamp (Date, required); objectId, createdAt, updatedAt (system).

Security:
- Only the user can update/delete their profile. Only the owner can create/delete their projects and associated tasks. Cloud Code validation is encouraged.

Auth:
- Sign-up, login, logout.

Behavior:
- List users, create projects and tasks, update statuses, and manage access.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for user profiles, projects, tasks, and status updates.
