How TLS/SSL Works: Logon and Authentication. How TLS/SSL Works. In this section. TLS/SSL authenticates and secures data transfers by using certificate- based authentication and symmetric encryption keys. This section discusses how the RFC- standard TLS protocol is used in the Windows Server 2.

This section is divided into five subsections: Schannel SSP Architecture illustrates how the Microsoft Security Support Provider Interface (SSPI) in Windows Server 2. Secure Channel (Schannel) Security Support Provider (SSP). TLS/SSL Architecture discusses the Handshake and Record Layer and related sub- protocols of TLS/SSL, as well as the Schannel session cache. TLS/SSL Protocol Processes and Interactions illustrates full handshake protocol, application data flow, resuming a secure session, and renegotiation with what is included in TLS messages. Some processes — such as certificate mapping, and how internally renegotiations are handled — are specific to Windows systems and might or might not differ in other implementations of the TLS protocol.

Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as "SSL", are cryptographic protocols that provide.

The Windows Server 2. Internet. Transport Layer Security (TLS) 1.

Secure Sockets Layer 3. Secure Sockets Layer (SSL) 2. All three protocols provide authentication through the use of certificates and secure communication through a variety of possible cipher suites. The generic term cipher suite refers to a combination of protocols such as key exchange, bulk encryption, and message integrity. Because authentication relies on digital certificates, certification authorities (CAs) like Verisign are an important part of Secure Channel (Schannel).

A CA is a mutually trusted third party that confirms the identity of a certificate requestor (usually a user or computer), and then issues the requestor a certificate. The certificate binds the requestor’s identity to a public key. CAs also renew and revoke certificates as necessary.

For example, if a client is presented with a server’s certificate, the client computer might try to match the server’s CA against the client’s list of trusted CAs. If the issuing CA is trusted, the client will verify that the certificate is authentic and has not been tampered with. Microsoft Internet Explorer and Internet Information Services (IIS) make use of these protocols, and preferably TLS, for Secure Hypertext Transfer Protocol (HTTPS). This document focuses on TLS, because TLS is replacing SSL and PCT.

TLS is standardized in RFC 2. IETF RFC database.

Note. Throughout this document TLS/SSL refers to the common protocol features of Transport Layer Security and Secure Sockets Layer. TLS refers to only Transport Layer Security, and SSL refers to only Secure Sockets Layer.

Schannel SSP Architecture. The Windows Server 2. TLS/SSL protocols as a Security Support Provider SSP, a dynamic- link library (DLL) called Schannel that is supplied with the operating system.

Which SSP is used depends on the capabilities of the computer on the other side of the connection and the configuration of the individual application that is being used. The Microsoft Security Support Provider Interface (SSPI) is the foundation for authentication in Windows Server 2. That is, applications and infrastructure services that require authentication use SSPI to provide it. The SSPI is the implementation of the Generic Security Service API (GSSAPI) in Windows Server 2.

Article ID -- Article Title. FD36152 - Technical Note: FortiGate is not forwarding TCP ports 5060, 50 FD40558 - Technical Note: Error 'Unable to establish.

For more information about GSSAPI, see RFC 2. RFC 2. 74. 4 in the IETF RFC database. The default SSPs in Windows Server 2. Kerberos, NTLM, Digest, Schannel, and Negotiate authentication protocols — are incorporated into the SSPI in the form of DLLs.

Additional SSPs can be incorporated if they can interoperate with the SSPI. SSPI Architecture In the Windows Server 2. SSPI provides a mechanism that carries authentication tokens over the existing communication channel between the client and server.

When two parties need to be authenticated so that they can communicate more securely, the requests for authentication are routed to the SSPI, which completes the authentication process, regardless of the network protocol currently in use.

The SSPI returns transparent binary large objects, and then these are passed between the applications, at which point they can be passed to the SSPI layer on that side. Thus, the SSPI enables an application to use various security models available on a computer or network without changing the interface to the security system. The following table describes the SSP components that are plugged into the SSPI. Each of the protocols in the table is used in different ways in Windows Server 2. SSP Layer Components.

Kerberos V5 authentication. An industry- standard protocol that is used with either a password or a smart card for interactive logon. It is also the preferred authentication method for services in Windows 2. Windows Server 2. NTLM authentication. A challenge- response protocol that is used to provide compatibility with versions of Windows earlier than Windows 2.

Digest authentication. An industry standard that is used in Windows Server 2. Lightweight Directory Access Protocol (LDAP) and Web authentication. Digest transmits credentials across the network as a Message Digest 5 (MD5) hash or message digest. Schannel. An SSP that implements SSL and TLS.

Schannel is used for applications used in cross- organization environments, such as Web- based server authentication, in which a user attempts to access a secure Web server or corporate access using VPN. Negotiate. An SSP that can be used to negotiate a specific authentication protocol. When an application calls into SSPI to log on to a network, it can specify an SSP to process the request. If the application specifies Negotiate, Negotiate analyzes the request and picks the best SSP to handle the request, based on customer- configured security policy. Secure Channel SSPYou can use the Secure Channel (Schannel) SSP for access to Web- enabled services, such as e- mail or personal information served on Web pages. The Schannel SSP uses public key certificates to authenticate parties. It includes four authentication protocols in its suite.

When authenticating parties, it will select one of the four protocols in the following order of preference. TLS version 1. 0. SSL version 3. 0. PCT. PCT is turned off by default in Windows Server 2. PCT has been superseded by Secure Sockets Layer 3. TLS protocol. The Schannel SSP supports PCT 1. For example, if a server supports all four Schannel protocols and the client supports only SSL 3.

PCT, Schannel uses SSL 3. TLS/SSL Architecture. The Schannel authentication protocol suite is based on public key cryptography. The Schannel suite includes Transport Layer Security (TLS), Secure Sockets Layer (SSL) version 3. SSL version 2. 0, and Private Communications Transport (PCT).

All Schannel protocols are based on a client/server model. An Schannel client sends a message to a server, and the server responds with the information needed to authenticate itself. The client and server perform an additional exchange of session keys, and the authentication dialogue ends. Aja Ki Pro Rack Software Download.

When authentication is completed, secure communication can begin between the server and the client using the secret keys established during the authentication process. Schannel does not require server keys to be stored on domain controllers or in a database, such as Active Directory. Clients, however, must be able to confirm the validity of credentials with a trusted authority.

Schannel validates the credentials with the root CA’s certificates, which are loaded when you install Windows Server 2. Therefore, users do not need to establish accounts before authenticating and creating a secure connection with a server. The TLS/SSL security protocol is layered between the application protocol layer and the TCP/IP layer, where it can secure and send application data to the transport layer.
