Permission Model

Permission Sets

flowchart LR
    subgraph PS["PERMISSION SETS"]
        subgraph ADMIN["FTS_App_Access<br/>(Administrators)"]
            A1["App: FlexibleTeamShare"]
            A2["Tabs: All visible"]
            A3["Apex: All classes"]
            A4["Objects: Full CRUD + MAR"]
            A5["Team_Sharing_Config: CRUD"]

        subgraph USER["FTS_Data_Access<br/>(End Users)"]
            U1["ObjectTeamMember__c: CRUD"]
            U2["Team_Sharing_Config__c: Read"]
            U3["Apex: Controller only"]
            U4["No View/Modify All Records"]
        end
    end

Permission Set	Audience	Capabilities
FTS_App_Access	Administrators	Full app access, all tabs, all Apex classes, full CRUD + Modify All Records on objects, Team_Sharing_Config CRUD
FTS_Data_Access	End Users	ObjectTeamMember__c CRUD, Team_Sharing_Config__c Read, controller Apex classes only, no View/Modify All Records

Access Control Logic

flowchart TB
    START["Who can manage<br/>team members?"] --> CHECK1{"System<br/>Administrator?"}
    CHECK1 -->|Yes| ALLOWED["ALLOWED"]
    CHECK1 -->|No| CHECK2{"Record<br/>Owner?"}
    CHECK2 -->|Yes| ALLOWED
    CHECK2 -->|No| CHECK3{"Team Member with<br/>Role = Manager<br/>or Owner?"}
    CHECK3 -->|Yes| ALLOWED
    CHECK3 -->|No| DENIED["DENIED"]

The isCurrentUserManager() method determines who can manage team members:

1. System Administrators — always allowed
2. Record Owners — always allowed
3. Manager/Owner role team members — allowed
4. Everyone else — denied

CRUD/FLS Enforcement

flowchart LR
    subgraph CRUD["CRUD/FLS Checks"]
        C["Create"] --> C1["isCreateable()"]
        U["Update"] --> U1["isUpdateable() +<br/>isCurrentUserManager()"]
        D["Delete"] --> D1["isDeletable() +<br/>isCurrentUserManager()"]
        R["Read"] --> R1["WITH USER_MODE"]
    end

    subgraph LOC["Execution Mode"]
        L1["Enforced in Controller"]
        L2["Elevated Access<br/>(without sharing)"]
        L3["Respects OWD/Sharing"]
    end

    C1 --> L1
    U1 --> L2
    D1 --> L2
    R1 --> L3

Operation	Security Check	Implementation
Create Team Member	Schema.sObjectType.ObjectTeamMember__c.isCreateable()	Enforced in controller
Update Team Member	isUpdateable() + isCurrentUserManager()	Elevated access (without sharing) after authorization
Delete Team Member	isDeletable() + isCurrentUserManager()	Elevated access (without sharing) after authorization
Read Team Members	WITH USER_MODE / sharing model	Respects OWD/sharing

Note

Update and Delete operations use elevated access (without sharing) to allow managers to modify any team member on the record, not just ones they created. Authorization is always checked first via isCurrentUserManager().

Input Validation

Input	Validation	Location
recordId	Not blank, valid Salesforce ID format	Controller
userId	Not blank, valid User ID	Controller
accessLevel	Not blank, valid picklist value	Controller + Picklist
role	Not blank, valid picklist value	Controller + Picklist
endDate	Must be future date or null	Controller + Validation Rule
objectApiName	Derived from Salesforce ID (not user input)	Controller

Validation Rules

Rule	Object	Description
End_Date_Cannot_Be_Past	ObjectTeamMember__c	Prevents setting end date in the past

Access Level Mapping

        O1["Read"]

    end

    I1 --> O1
    I2 --> O2

Security Best Practices Implemented

Control	Status	Implementation
CRUD checks in controllers	Implemented	isAccessible(), isCreateable(), isUpdateable(), isDeletable()
FLS enforcement	Implemented	Permission Sets control field access
SOQL injection prevention	Implemented	Bind variables for user input, whitelist for object names
Sharing model	Implemented	with sharing on controllers, without sharing only where documented
Input validation	Implemented	Null checks, format validation, business rules
XSS prevention	Implemented	LWC framework handles output encoding

External Integration Security

Check	Result
HTTP Callouts	None — package makes no external calls
Named Credentials	Not used
External Objects	Not used
Remote Site Settings	Not required
CSP Violations	Pass — no Content-Security-Policy violations
