Explanation: In order to resolve the issue, you should use TLS (Transport Layer Security). Transport Layer Security (TLS) is a cryptographic protocol that provides security and data integrity for communications over networks such as the Internet. TLS and SSL encrypt the segments of network connections at the Transport Layer end-to-end. Several versions of the protocols are in wide-spread use in applications like web browsing, electronic mail, Internet faxing, instant messaging, and voice-over-IP (VoIP). The TLS protocol, an application layer protocol, allows client/server applications to communicate across a network in a way designed to prevent eavesdropping, tampering, and message forgery. TLS provides endpoint authentication and communications confidentiality over the Internet using cryptography. Answer: C is incorrect. Internet Protocol Security (IPSec) is a method of securing data. It secures traffic by using encryption and digital signing. It enhances the security of data as if an IPSec packet is captured, its contents cannot be read. IPSec also provides sender verification that ensures the certainty of the datagram’s origin to the receiver. Answer: D is incorrect. Hypertext Transfer Protocol Secure (HTTPS) protocol is a protocol used in the Universal Resource Locater (URL) address line to connect to a secure site. If a site has been made secure by using the Secure Sockets Layer (SSL) then HTTPS, instead of HTTP protocol, should be used as a protocol type in the URL. Answer: A is incorrect. The SCP (secure copy) protocol is a network protocol that supports file transfers. The SCP protocol, which runs on port 22, is based on the BSD RCP protocol which is tunneled through the Secure Shell (SSH) protocol to provide encryption and authentication. SCP might not even be considered a protocol itself, but merely a combination of RCP and SSH. The RCP protocol performs the file transfer and the SSH protocol performs authentication and encryption. SCP protects the authenticity and confidentiality of the data in transit. It hinders the ability for packet sniffers to extract usable information from the data packets.
