There is a renewed interest in the IETF to increase the security of
transmissions over the Internet. Many application protocols have defined
methods for using TLS to authenticate the server (and sometimes the client),
and to encrypt the connection between the client and server. However, there is
a diversity of definitions and requirements, and that diversity has caused
confusion for application developers and also has led to lack of
interoperability or lack of deployment. Implementers and deployers are faced
with multiple security issues in real-world usage of TLS, which currently does
not preclude insecure ciphers and modes of operation.

This WG has the following tasks:

- Update the definitions for using TLS over a set of representative application
protocols

- Specify a set of best practices for TLS clients and servers, including but
not limited to recommended versions of TLS, using forward secrecy, and one or
more ciphersuites and extensions that are mandatory to implement

- Define a standard way for an application client and server to use
unauthenticated encryption through TLS when server and/or client authentication
cannot be achieved

- Create a document that helps application protocol developers use TLS in
future application definitions

The initial set of representative application protocols is SMTP, POP, IMAP,
XMPP, and HTTP. It is expected that other protocols that use TLS might later be
updated using the guidelines from this WG, and that those updates will happen
through other WGs or through individual submission.

The WG will make the fewest changes needed to achieve good interoperable
security for the applications using TLS.

This WG will collaborate with other IETF WGs, in particular with the TLS and
DANE WGs.
