Abstract: The secure transfer of files over the internet is a pressing concern in today's digital environment. Sensitive data, spanning personal, corporate, and governmental domains, is frequently transmitted over networks susceptible to numerous cyber threats. These threats include unauthorized access, data breaches, interception during transmission, and exploitation of system vulnerabilities. Traditional file transfer methods, such as email attachments and basic file transfer protocols, often lack adequate security measures, exposing data to risks like man-in-the-middle attacks, phishing, malware, and ransomware. The increasing sophistication of cyber-attacks, alongside stringent regulatory requirements for data protection, underscores the urgent need for robust, secure file transfer solutions [1, 2]. Unauthorized access poses a significant risk where attackers gain entry to files without permission, leading to data breaches that cause financial and reputational damage [3]. Data interception during transmission is another critical issue, as data can be captured and manipulated while in transit [4]. System vulnerabilities, such as weak passwords, unpatched software, and inadequate encryption, further increase the risk, providing attackers with opportunities to exploit these weaknesses [5]. Additionally, phishing and social engineering attacks deceive users into revealing sensitive information or downloading malicious software, compromising the security of file transfers [6]. Malware and ransomware attacks encrypt data or demand a ransom, disrupting operations and causing substantial losses [7]. The prevalence of these threats renders traditional file transfer methods inadequate for ensuring the security and integrity of sensitive data. To address these challenges, a comprehensive solution is proposed: The Secure File Transfer Website. This system is built on a robust client-server architecture designed to provide a secure environment for file transfer operations. Users can securely upload files, which are encrypted to guarantee end-to-end security during transmission. Advanced techniques are employed to ensure encryption keys are securely embedded, rendering intercepted files inaccessible without the proper decryption keys [1]. The system sends SMS notifications with secure download links upon file uploads, enhancing security and timely access. Overall, the Secure File Transfer Website effectively protects sensitive data from unauthorized access and cyber threats, providing a reliable platform for users [5].
