WS-Security describes binary security token soapui to SOAP messaging to provide quality of protection through message integrity, message confidentiality, and single message authentication. These mechanisms can be used to accommodate a wide variety of security models and encryption technologies.
WS-Security also provides a general-purpose mechanism for associating security tokens with messages. No specific type of security token is required by WS-Security. It is designed to be extensible e. For example, a client might provide proof of identity and proof that they have a particular business certification.
Additionally, WS-Security describes how to encode binary security tokens. Specifically, the specification describes how to encode X.
It also binary security token soapui extensibility mechanisms that can be used to further describe the characteristics of the credentials that are included with a message. By itself, WS-Security does not ensure security nor does it provide a complete security solution. WS-Security is a building block that is used in conjunction with other Web service and application-specific protocols to accommodate a wide variety binary security token soapui security models and encryption technologies.
Implementing WS-Security does not mean that an application cannot be attacked or that the security cannot be compromised. WS-Security and related specifications are provided as-is and for review and evaluation only. IBM and Microsoft and VeriSign hope to solicit your contributions and suggestions in the near future. IBM and Microsoft and VeriSign make no warrantees or representations regarding the specifications in any manner whatsoever.
This specification proposes a standard set of SOAP extensions that can be used when building secure Web services to implement integrity and confidentiality. Specifically WS-Security provides support for multiple security tokens, multiple trust domains, multiple signature formats, and multiple encryption technologies. This specification provides three main mechanisms: These mechanisms by themselves do not provide a complete security solution. Instead, WS-Security is a building block that can be used in conjunction with other Web service extensions and higher-level application-specific protocols to accommodate a wide variety of security models and encryption technologies.
These mechanisms can be used independently e. This specification is intended to provide a flexible set of mechanisms that can be used to construct a range of security protocols; in other words this specification intentionally does not describe explicit fixed security protocols.
As with every security protocol, significant efforts binary security token soapui be applied to ensure that security protocols constructed using WS-Security are not vulnerable to a wide range of attacks. The Web services security language must support a wide variety of security models. The following list identifies the key driving requirements for this specification: Multiple security tokens for authentication or authorization Multiple trust domains Multiple binary security token soapui technologies End-to-end message-level security and not just transport-level security 1.
Non-Goals The following topics are outside the scope of this document: Establishing a security context or authentication mechanisms that require multiple exchanges. Key exchange and derived keys How trust is established or determined.
Example The following example illustrates a message with a username security token:. The first two lines start the SOAP envelope. Line begins the headers that are associated with this SOAP message. Lines to specify how to route this message as defined in WS-Routing.
This header contains security information for an intended receiver. This element continues until line Lines to specify a security token that is associated with the message.
Lines to specify a digital signature. This signature ensures the integrity of the signed elements that they aren't modified. The signature uses the XML Binary security token soapui specification. In this example, the signature is based binary security token soapui a key generated demo online handel mit binare optionen the users' password; typically stronger signing mechanisms would be used see the Extended Example below.
Lines to describe the digital signature. Line specifies how to canonicalize normalize the data that is being signed. Lines to select the elements that are signed. In this example only binary security token soapui message body is signed; typically additional elements of the message, such as parts of the routing header, should be included in the signature see the Extended Example below.
Line specifies the signature value of the canonicalized form of the data that is being signed as defined in the XML Signature specification. Lines to provide a hint as to where to find the security token associated with this signature.
Specifically, lines to indicate that the security token can be found at pulled from the specified URL. Lines to contain the body payload of the SOAP message. The current SOAP 1. Readers are presumed to be familiar with the terms in the Internet Security Glossary.
Signature - A signature is a cryptographic binding of binary security token soapui proof-of-possession and a digest. This covers both symmetric key-based and public key-based signatures. Consequently, non-repudiation is not always achieved. In order to secure a SOAP binary security token soapui, two types of threats should be considered: In this document we specify an abstract message security model in terms of security tokens combined with digital signatures as proof of possession of the security token key.
As well, the signature can be used to "bind" or "associate" the signature with the claims in the security token assuming the token is trusted. Note that such a binding is limited to those elements covered by the signature.
Furthermore note that this document does not specify a particular method for authentication, it simply indicates that security tokens MAY be bound to messages. A claim can be either endorsed or unendorsed by a trusted authority. A set of endorsed claims is usually represented as a signed security token that is digitally signed or encrypted by the authority. An endorsed binary security token soapui can also be represented as a reference to an authority so that the receiver can "pull" the claim from the referenced authority.
An unendorsed claim can be trusted if there is a trust relationship between the sender and the receiver. For example, the unendorsed claim that the sender is Bob is sufficient for a certain receiver to believe that the sender is in fact Bob, if the sender and the receiver use a trusted connection and there is an out-of-band trust relationship between them. One special type of unendorsed claim is Proof-of-Possession.
Such a claim proves that the sender has a particular piece of knowledge that is verifiable by, appropriate actors. A Proof-of-Possession claim is sometimes combined with other security tokens to prove the claims of the sender. Note that a digital signature used for message integrity can also be used as a Proof-of-Possession claimalthough in this specification we do not consider such a digital signature as a type of security token.
It should be noted that this security model, by itself, is subject to multiple security attacks. Refer to the Security Considerations section for additional details. Protecting the message content binary security token soapui being intercepted confidentiality or illegally modified integrity are primary security concerns.
Message integrity is provided by leveraging XML Signature in conjunction with security tokens to ensure that messages are transmitted without modifications. The integrity mechanisms are designed to support multiple signaturespotentially by binary security token soapui actors, and to be extensible to support additional signature formats.
The encryption mechanisms are designed to support binary security token soapui encryption processes and operations by multiple actors. The message receiver SHOULD reject a message with invalid signature, missing or inappropriate claims as it is an unauthorized or malformed message.
This specification provides a flexible way for the message sender to claim the security properties by associating zero or more security tokens with the message. An example of a security claim is the identity of the sender; the sender can claim that he is Bob, known as an employee of some company, and therefore he has the right to send the message.
This MAY be either the ultimate receiver of the message or an intermediary. Note that this specification does not impose any specific order of processing the sub-elements.
The receiving application can use whatever policy is needed. When a sub-element refers to a key carried in another sub-element for example, a signature sub-element that refers to a binary security token sub-element that contains the X. This is the header block for passing security-related message information to a receiver. This attribute allows a specific SOAP actor to be identified. This attribute is not required; however, no two instances of the header block may omit an actor or specify the same actor.
This is an extensibility mechanism to allow different extensible types of security information, based on a schema, to be passed. This is an extensibility mechanism to allow additional attributes, based on schemas, to be added to the header. This optional element provides password information. This optional attribute specifies the type of password being provided.
The following table identifies the pre-defined types:. A binary security token binary security token soapui two attributes that are used to interpret it. The ValueType attribute indicates what the security token is, for example, a Kerberos ticket. The EncodingType tells how the security token binary security token soapui encoded, for example Base64Binary. The BinarySecurityToken element defines a security token that is binary encoded.
The encoding is specified using the EncodingType attribute, and the value type and space are specified using the ValueType attribute.
An optional string label for this security token. The ValueType attribute is used to indicate the "value space" of the encoded binary data e.
The ValueType attribute allows a qualified name that defines the value type and space of the encoded binary data.
