How does a firewall enhance the security of banking applications?

A firewall enhances the security of banking applications by monitoring and controlling network traffic based on predefined security rules. This functionality is crucial in a banking environment where sensitive financial information is regularly transmitted and accessed.

By filtering inbound and outbound traffic, firewalls can block unauthorized access attempts, prevent data breaches, and mitigate various cyber threats such as denial-of-service attacks or other forms of malicious activities. The ability to establish rules that dictate permissible traffic enhances the overall security posture by allowing only legitimate users and communications while denying access to suspicious or harmful connections.

This proactive management of traffic ensures that banking applications remain secure from external threats, making it a fundamental component of a comprehensive security strategy. While encryption and user access control are important elements of security, they serve different purposes and do not encompass the specific traffic management role that firewalls provide.
