Explanation

Encryption in transit is a method that could be used to prevent passive attacks against secure voice communications between an organization and its vendor. Encryption in transit is a technique that encrypts the data while it is being transmitted over a network, such as the Internet, a phone line, or a wireless connection. Encryption in transit can protect the data from eavesdropping, interception, or modification by unauthorized parties, such as passive attackers who monitor the network traffic. Encryption in transit can be achieved by using protocols such as Secure Sockets Layer (SSL), Transport Layer Security (TLS), Secure Shell (SSH), or Internet Protocol Security (IPsec), which provide encryption, authentication, and integrity for the data.
