In a recent LinkedIn post, Chirag Goswami provides a clear and concise overview of essential network protocols, breaking down their functions and importance for understanding modern digital infrastructure. Goswami, an advocate for robust cybersecurity and network architecture, aims to educate professionals on the fundamental building blocks of internet communication.
The post begins by defining network protocols as the rules that govern how devices communicate and exchange data. Goswami emphasizes their critical role in ensuring reliable connectivity across both the internet and private networks.

Understanding Core Web Protocols: HTTP vs. HTTPS
A significant portion of Goswami’s explanation focuses on the distinction between HTTP and HTTPS, two protocols vital for web browsing. According to Chirag Goswami, HTTP (Hypertext Transfer Protocol) is the standard for transferring web pages between browsers and servers.
However, Goswami points out a critical security limitation of HTTP: it does not encrypt data in transit. This lack of encryption leaves sensitive information vulnerable to interception.
In contrast, Chirag Goswami highlights HTTPS (Hypertext Transfer Protocol Secure) as the solution for secure web communication. He explains that HTTPS utilizes TLS (Transport Layer Security) to encrypt data, thereby protecting sensitive information.
“HTTPS secures web communication by encrypting data with TLS, protecting sensitive information from interception”
File Transfer and Data Reliability: FTP, TCP, and UDP
Moving beyond web browsing, Goswami’s post delves into protocols for file transfer and data delivery. He addresses FTP (File Transfer Protocol), noting its function in enabling file transfers between clients and servers. However, Chirag Goswami strongly advises against its use for sensitive data, recommending secure alternatives like SFTP or FTPS instead.
The discussion then pivots to data transmission reliability. Chirag Goswami explains TCP (Transmission Control Protocol) as a protocol that guarantees reliable, ordered, and error-checked delivery of data. He identifies it as ideal for applications where data integrity is paramount, such as web browsing, email, and file transfers.
Conversely, Goswami introduces UDP (User Datagram Protocol) as a protocol that prioritizes speed over reliability. This makes UDP suitable for real-time applications like live streaming, VoIP, and online gaming, where slight data loss is acceptable in exchange for lower latency.

The Role of IP and the Importance of Protocol Knowledge
Chirag Goswami also clarifies the function of IP (Internet Protocol). According to the post, IP is responsible for the addressing and routing of data packets, ensuring they reach their intended destination across various networks.
Goswami concludes by underscoring the practical importance of understanding these protocols. He argues that this knowledge is essential for effective network troubleshooting, designing secure IT infrastructure, and conducting robust cybersecurity operations.
The insights shared by Chirag Goswami serve as a valuable primer for anyone involved in IT, networking, or cybersecurity, offering a clear breakdown of the technologies that underpin our digital world. His company, Cybernara, is positioned as a resource for organizations seeking to enhance their network security and communication protocols.
