What protocol is used by port 4747 for communication?

Port 4747 is used specifically for communication involving the Qlik Sense services, and it operates over the HTTPS protocol. HTTPS is the secure version of HTTP, incorporating encryption to protect data integrity and confidentiality during transmission. This is particularly important in enterprise applications like Qlik Sense, where sensitive data often needs to be communicated between various components securely over the network.

Utilizing HTTPS on port 4747 ensures that any communication between the Qlik Sense services is encrypted, helping to safeguard against potential eavesdropping or tampering. This is crucial in maintaining the security of the data being processed and the connections made to various Qlik Sense services.

In contrast, other protocols such as HTTP, FTP, and Telnet do not provide this level of security. While HTTP is used for regular web traffic, it does not encrypt data. FTP is primarily used for file transfers and lacks encryption by default, making it vulnerable for data interchange. Telnet is an older protocol for remote command line access and does not offer encryption either, which poses significant security risks in modern applications. Therefore, HTTPS is the appropriate protocol for secure communication on port 4747 in the context of Qlik Sense.
