Since both of those systems speak the same language — SAML — the user only needs to log in once. Each identity provider and service provider need to agree upon the configuration for SAML. Both ends need to have the exact configuration for the SAML authentication to work. OAuth is a slightly newer standard that was co-developed by Google and Twitter to enable streamlined internet logins. Identity management best practices require user accounts to be both limited to only the resources the user needs to do their job and to be audited and managed centrally.
By using an SSO solution, you can disable accounts from one system and remove access to all available resources at once, which protects your data from theft.

Inside Out Security. Your specification template should layout clear milestones. If your client writes the functional and user interface design, you should subsequently agree on a set of milestones. Sometimes these are billing thresholds as well, but at the very least they provide a clear metric toward completion.
When possible, milestones should be approximately equal in duration. Of course, this template should be adjusted as-needed. He approaches the document slightly differently, but shares a similar sentiment. What does the application do? What application states high-level descriptions of core user scenarios will the user encounter?
For example, your UI description might look like:. There will always be details that neither of you had considered, and both you and the client will, while looking at the intermediate results, encounter new ideas, design changes, unexpected design flaws, and unworkable suggestions.
The design will evolve, and the changes should be captured in your document. Even then, I created a design document with detailed specifications, and adjusted it as necessary. Above all, keep in touch. At least several times a week, contact your client, report on your progress, ask for clarification, and make certain that you share identical visions. As a litmus test for your communication, try and ensure that you and your client give the same answers to these three questions:.
SDD stands for software design document or software design description. A functional design document describes a software product's capabilities, appearance, and functions it needs to ultimately perform. Design documents are also referred to as functional specifications or functional specifications documents FSDs , or functional requirements specifications.
A high-level design document HLDD describes the architecture used in the development of a particular software product. It usually includes a diagram that depicts the envisioned structure of the software system. Since this is a high-level document, non-technical language is often used. The software design document SDD typically describes a software product's data design, architecture design, interface design, and procedural design. Subscription implies consent to our privacy policy. The user wants to log in to a remote application, such as a support or accounting application the service provider.
The following happens:. The user accesses the remote application using a link on an intranet, a bookmark, or similar and the application loads. This is the authentication request. The user either has an existing active browser session with the identity provider or establishes one by logging into the identity provider. The service provider, which already knows the identity provider and has a certificate fingerprint, retrieves the authentication response and validates it using the certificate fingerprint.
The diagram below illustrates the single sign-on flow for service provider-initiated SSO, i.
