1 Use strong authentication

Authentication is the process of verifying the identity of a user or a device that wants to access your financial application. You should use strong authentication methods, such as passwords, biometric scans, one-time codes, or multi-factor authentication (MFA). MFA is a technique that requires two or more pieces of evidence to grant access, such as something you know (password), something you have (phone), or something you are (fingerprint). MFA can reduce the risk of credential theft, phishing, and brute-force attacks.

2 Encrypt data in transit and at rest

Encryption is the process of transforming data into an unreadable format that can only be deciphered by authorized parties. You should encrypt your data both in transit and at rest. Data in transit is the data that flows between your financial application and other systems, such as servers, databases, or third-party services. Data at rest is the data that is stored on your devices, disks, or cloud platforms. Encrypting data can protect it from interception, modification, or theft by unauthorized parties.

3 Implement access control policies

Access control is the process of defining who can access what data and functions in your financial application. You should implement access control policies that follow the principle of least privilege, which means granting the minimum level of access necessary for each user or role. For example, you can restrict access to sensitive data, such as personal information, financial records, or transaction details, to only authorized employees or customers. You can also limit access to certain functions, such as creating, modifying, or deleting data, to only authorized users or roles. Access control can prevent unauthorized or accidental changes, leaks, or misuse of data.

4 Monitor and audit activities

Monitoring and auditing are the processes of collecting, analyzing, and reporting on the activities and events that occur in your financial application. You should monitor and audit your application for any unusual or suspicious behavior, such as failed login attempts, unauthorized access, data tampering, or performance issues. You should also log and track the actions and changes made by users or devices, such as creating, modifying, or deleting data, or performing transactions. Monitoring and auditing can help you detect and respond to security incidents, identify and fix vulnerabilities, and comply with regulations and standards.

5 Educate and train users

Education and training are the processes of informing and instructing the users of your financial application about the security risks and best practices. You should educate and train your users, such as employees, customers, or partners, on how to use your application securely and responsibly. For example, you can teach them how to create and manage strong passwords, how to recognize and avoid phishing emails, how to report and handle security incidents, and how to protect their devices and data. Education and training can increase the awareness and skills of your users, and reduce the likelihood of human errors or negligence.

Ensure to implement right Identity Management solution to control the user access along with the implemention of Lifecycle management for Onboarding and off boarding process. It’s important to prevent exfiltration of enterprise or protected data, and raises alerts and alarms when access attempts are made by unauthorized personnel or programs, whether from inside or outside the enterprise perimeter.

There is security in simplicity and separation of tasks. For example, if the application operates on simple datatypes such as .csv or .txt, the sharing of data through uploads and downloads between the application and the client machine leaves less room for IT security vulnerabilities. If the application uses open-source software, which of course must be thoroughly tested for IT security vulnerabilities, there is also some security in separating this code from client machines and onto isolated servers.
