Abstract

The emergence of wireless networks has promoted the ease, immediacy and efficiency of access and transacting financial internet services. Nonetheless, such developments offer chances of severe criminal activities, including information violations, identity theft, and data leakage. The paper reviews protective structures of financial internet services, emphasizing secure wireless convenience and connection. It evaluates the vulnerabilities of Wi-Fi, LTE, and emerging 5G wireless communication technologies concerning confidentiality, integrity, and availability of sensitive financial information. A layered security approach towards wireless transactions is proposed and it includes end-to-end encryption, multifactor authentication, VPNs and advanced intrusion detection systems (IDS). Moreover, blockchain is regarded with zero-trust frameworks to enhance trust and transparency in the financial systems. Cases of cyberattack on financial infrastructures have revealed flaws in the current systems, demonstrating vulnerabilities in current wireless security frameworks. It is based on these trends of flexibility to develop this model to articulate the policies of the electronic security in wireless networks without infringing on the standards of PCI-DSS and GDPR. The hyper-connected world enables service providers to manage risk more effectively and deliver services safely to users by introducing risk-enhancing principles that amplify networks and financial systems. This study will be part of the overall process of improving the cybersecurity condition and resilience of financial technologies to more complex and varied vectors of cyber threats.
