John, your role at MMT Digital involved implementing automated and secure Stripe payment systems. Can you describe how you ensured the security of sensitive financial data during transmission and storage?

Security of financial data is paramount, especially when dealing with payment systems. At MMT Digital, I took a number of steps to ensure that sensitive data was protected during transmission and storage. The company reputation and trust is all that matters to them, so I made sure that was kept in mind.I used HTTPS to encrypt all data transmitted between the client and the server. This prevented eavesdropping and man-in-the-middle attacks. I used and had to become proficient with lots of those systems. It really is amazing what goes on the hood and the coding that has been used.I also tokenized sensitive data, such as credit card numbers, before storing it in the database. Tokenization replaces sensitive data with non-sensitive substitutes, making it useless to attackers if the database is compromised. It is extremely useful and good, that a system such as Stripe can handle all of this.I also implemented strong access controls to restrict access to sensitive data. Only authorized users were able to access the data, and they were only granted the permissions they needed to perform their job functions. The access controls should be restricted as much as possible, with the principle of minimal access and ensuring that if people leave the company, that their profiles and access are immediately removed. Access can be given and taken away.I also regularly audited the security of the payment system to identify and address any vulnerabilities. This involved performing penetration tests and code reviews. Any code that gets written, should have lots of eyeballs reviewing and testing, as the responsibility for it is with all of the team. This helps, and is not all on one person only, which is more ideal.In general, with security, you can never be sure about how good it is, it is better to always iterate and have different scenarios to protect it. Better to think of 10 different scenarios than only thinking of 1. At MMT Digital, I ensured the security of Stripe payment systems by using HTTPS to encrypt data during transmission, tokenizing sensitive data before storage, implementing strong access controls, and regularly auditing the security of the payment system to identify and address vulnerabilities.
