Access Control Patterns
Implement robust access control mechanisms using `Ownable`, `Pausable`, and role-based access control (RBAC) patterns.
What is Access Control?
In smart contracts, access control defines who can perform specific actions. It's like setting permissions on a file or folder.
Without proper access control, anyone could call sensitive functions, leading to vulnerabilities or unintended behavior.
Why It's Crucial
Imagine a contract that manages funds or critical system settings. You wouldn't want just anyone to be able to:
- Withdraw all funds.
- Change the contract's owner.
- Pause essential operations.
Access control is a fundamental security measure.
