Only give people access to customer card data if they absolutely need it for their job. This rule is called "least privilege" – giving users the minimum access they need to do their work.
For example:
- IT administrators get special access to manage computers
- Customer service staff only see the information they need to help customers
- Accounting staff only access financial systems
Why Is This Important?
Limiting access protects your business in three ways:
- Prevents accidents – People can't accidentally change settings or delete important data if they don't have access to it.
- Reduces security risks – If someone's account gets hacked, the damage is limited to only what that person could access.
- Protects sensitive information – Employees only see the data they need for their specific job, keeping customer information private.
The basic rule
Ask yourself: "Does this person need access to do their job?"
If yes → Give them access
If no → Don't give them access
It's that simple. Only give people access to systems and data they actually need to use."
