Which protocol is commonly used for secure communication in a Cortex environment?

In a Cortex environment, secure communication is vital to protect sensitive information from unauthorized access and to maintain data integrity during transmission. HTTPS, which stands for Hypertext Transfer Protocol Secure, is the correct choice for this purpose. It is the secure version of HTTP, incorporating SSL/TLS protocols to encrypt data sent over the internet. This encryption helps to ensure that the information exchanged between a client and a server is secure and cannot be easily intercepted by malicious actors.

The use of HTTPS is critical in contexts like Cortex, where data security is a top priority. It establishes a secure channel that not only protects the confidentiality of the information but also authenticates the communicating parties, making it a trusted protocol in many modern applications.

In contrast, HTTP does not provide any encryption, leaving data vulnerable to interception. FTP (File Transfer Protocol) is primarily used for transferring files but lacks security, making it unsuitable for sensitive data exchange. Telnet is also an insecure protocol used for accessing remote computers; it transmits data in plaintext, which can easily be intercepted, further underscoring the importance of using secure protocols like HTTPS in a professional environment.
