In IT infrastructure, security is the first and foremost important factor to maintain a system’s confidentiality, integrity and availability. Compromising any of these factors can have disastrous effects on a system or a company. History has taught us the consequences of neglecting security needs. So, information security has become a topic of interest and various researchers are introducing different methodologies to secure the systems. Firewalls, Intrusion Detection Systems (IDSs), Endpoint Detection & Response (EDR), Managed Detection & Response (MDR), etc., are some famous security solutions that have enhanced the security of cyber-physical systems. Moreover, there are various advancements in cryptography and many new algorithms are being suggested by researchers. This work presents a novel approach to secure data communication within a network where the information can be vulnerable during transit. This work uses a Raspberry Pi in router creation, and a Virtual Private Network (VPN) is deployed over the router through a cloud link. AWS is being utilized in cloud knot. Thus, a secure gateway is formed in which the data is encrypted, and even the network admin or service provider cannot read the data. Advanced Encryption Standard (AES) has been used as an encryption algorithm in this work. The prototype is tested via IP and network traffic tests, and results verified that this router’s network traffic is secure over the internet.
