Datagram Transport Layer Security (DTLS) is a communications protocol that provides security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.
FAQ - Stunnel Can I forward UDP services over stunnel? As described thus far, no. Stunnel works with SSL, which runs only on TCP. There are ways to forward UDP packets over TCP, and in principle these should be able to work over stunnel. There are also other programs that do this natively, and could be used standalone or via stunnel, such as Zebedee. Computer Networks Chapter 2 Review Questions Flashcards The SSL socket takes unencrypted data from the application layer, encrypts it and then passes it to the TCP socket. If the application developer wants TCP to be enhanced with SSL, she has to include the SSL code in the application. For the client- server application over UDP, why may the client program be executed before the server program Port 993 (tcp/udp) :: SpeedGuide udp: imaps: imap4 protocol over TLS/SSL: IANA: 6 records found.

DNS over TLS, or DoT, is a standard for encrypting DNS queries to keep them secure and private. DoT uses the same security protocol, TLS, that HTTPS websites use to encrypt and authenticate communications. (TLS is also known as "SSL.") DoT adds TLS encryption on top of the user datagram protocol (UDP), which is used for DNS queries.
HTTPS over UDP is secure. This is because the security of HTTPS doesn't use any of the properties of TCP except that it is a transport layer. Just like UDP, TCP is easy to spoof and manipulate. TCP is only to make things more reliable, not more secure. With UDP, packets can …
While most popular services on the Internet run over the TCP protocol, UDP services are widely deployed. DNS, SNMP, and DHCP (registered ports 53, 161/162, and 67/68) are three of the most common. Because UDP scanning is generally slower and more difficult than TCP, some security auditors ignore these ports.
Testing Sophos SSL VPN over TCP or UDP – Which is Faster? My test base is two virtual Windows servers behind two virtual Sophos XG appliance with an SSL VPN Site-to-Site The Sophos XG devices are on the same virtual switch. This is, therefore, a high-speed reliable WAN configuration. The test is
