How does the principle of least privilege enhance security in payment systems?

The principle of least privilege enhances security in payment systems by ensuring that users are granted access only to the resources and information that are necessary for them to perform their job functions. This limitation reduces the potential attack surface, as it minimizes the number of resources that could be exploited by malicious actors.

When users have only the bare minimum access rights, the risk of unauthorized actions, data breaches, or accidental changes to sensitive information is significantly lowered. If a user's account is compromised, the damage can be contained more effectively, as the attacker will not have access to a wider range of systems or data.

In the context of payment systems, where data integrity and confidentiality are crucial, adhering to the principle of least privilege not only strengthens security but also helps in compliance with regulations and standards designed to protect sensitive financial information.
