DETAILED DESCRIPTION
In the following description, specific details are set forth although it should be appreciated by one of ordinary skill that the systems and methods can be practiced without at least some of the details. In some instances, known features or processes are not described in detail so as not to obscure the present invention.
Asset management systems such as the IBM Rational® Asset Manager can catalog and manage assets, which include a collection of golden software artifacts, or files that can be grouped together to solve a business solution. Artifacts can include work products from software development processes, such as software requirements, designs, models, source code, data, tests, user interfaces, and documentation. Assets can also include metadata, which provides information about the purpose, use, or relationship to other assets, permitting the assets to be traced for reuse and the like. The DSL of an asset management system can process software development outputs, or formal deliverables that a development project provides such as a “golden build” of a package, or generated binary that was scanned and tested. Other outputs can include packages, for example, click on Red Hat package manager (RPM), enterprise archive (EAR), or Java archive (JAR) hyperlinks, or test results output as hypertext markup language (HTML), PDF, or related forms, or documentation, and so on.
A uniform resource locator (URL) is typically used for providing asset traceability. For example, a URL can provide a link to a defect managed by a change management repository, or to a requirement managed by a requirement repository, where many change requests, code versions, and other software items may be allocated. The link can be an open community (OSLC) link or the like.
Asset management system users other than the asset creator, for example, consumers of an install package, typically do not have permission to access a data repository owning resources related to the asset, such as defects, builds, test results, and so on, which are typically located at a different tool/server. Users with permission to access that package, or asset, for example, may desire to fetch summary information corresponding to that package's related resources even though the consuming user does not have direct access to the repository owning these related resources. For example, a user may find it useful to view a link, e.g., from an install package asset, to a test plan summary resource; more specifically, to the test plan name, status, execution result/s, contact/owner information, or related summary information.
In accordance with embodiments of the present inventive concepts, an asset user can receive permission from the asset creator to view summary information corresponding to asset links, e.g., test plans, designs, requirements and so on, stored at a different repository, even though the user does not have the credentials to directly access the data itself directly. To achieve this, the asset creator authenticates with the linked resource target repository to retrieve an access token, and provides the asset management with the permission to use a token that toke in the future to render summary information about that linked resource to asset users, thereby avoiding the need to create a status report or summary document to be published with the asset. The asset management system can use the token to provide a compact rendering of a summary for repository resources linked when the asset user browses for data related to the asset. More specifically, a third party user with access to that software asset can be presented with summary information corresponding to the linked resource utilizing the asset owner's key, and the fact that the asset management server and target repository owning that resource server established a trust as servers can communicate with each other and share data by establishing a friend relationship and configuring OAuth access, referred to as friend servers. In this manner, tokens can be used instead of sensitive credential information to share restricted information between users of a system.
FIG. 1 illustrates a block diagram of a network environment 10 at which embodiments of the present inventive concepts can be practiced.
The network environment 10 provides electronic communications between various electronic devices, including but not limited to an asset management system 12, an asset management user computer 14, a data management repository 18, and a data distribution control system 26 geographically separate from each other and in communication with each other via a network 36. Alternatively, the asset management system 12, the asset management user computer 14, the data management repository 18, and/or the data distribution control system 26 can be directly connected, or co-exist at a same hardware device. The network 36 can include a public switched telephone network (PSTN), a mobile communications network, a data network, such as a local area network (LAN) or wide area network (WAN), or a combination thereof, or other communication network known to those of ordinary skill in the art. The electronic devices 12, 14, 18, 26 can also communicate with one or more information sources, for example, other data repositories. One or more of the electronic devices 12, 14, 18, 26 can include, but not limited to, personal computers, handheld devices, servers, or any other device that can generate and/or receive data or related electronic information. Each of the electronic devices 12, 14, 18, 26 includes a CPU or related processor, a memory device, e.g., a volatile or non-volatile memory, and an input/output (I/O) logic, e.g., a network interface card (NIC), for connecting to the network 36. The processor, the memory, and the I/O logic communicate with each other via a data/control bus and/or data connector, for example, a peripheral component interconnect (PCI) bus. Stored in the memory of the data distribution control system 26 can include program code which, when executed by a processor, can perform functions of the data distribution control system 26.
The asset management system 12 can manage and control the design, development, and consumption of software assets. The asset management system 12 can include a commercial system, for example, an IBM Rational® Asset Manager platform.
The data management repository 18 can include a definitive software library (DSL) 20, in which authorized versions of software package configuration items are stored and protected.
The data distribution control system 26 can facilitate an authorization process between the asset management system 12 and the data management repository 18, for example, providing an authorization token to the asset management system 12 for authorizing one or more third party users, i.e., users other than an asset creator, to receive information, for example, a compact summary rendering for a URL, at the data management repository 18.
In an embodiment, the data distribution control system 26 can notify the asset creator if a token expires. Accordingly, an asset to which the token corresponds can be updated, for example, the credentials can be updated. Alternatively, a new token can be provided that can be stored with the asset at the asset management system 12.
FIG. 2 is a flowchart of a method 200 for sharing restricted data, in accordance with an embodiment. The method 200 can be governed by instructions that are stored in a memory of one or more electronic devices, for example, the asset management system 12, the asset management user computer 14, the data management repository 18, and/or the data distribution control system 26 of FIG. 1.
At block 202, an asset creator can authorize one or more third party users, access to data at a target repository, for example the data management repository 18. The third party users are otherwise not permitted to access the target repository, for example, due to insufficient credentials or other security-related limitations. The data can be summary information corresponding to the asset, for example, summary information related to defects, requirements, tests, builds, and so on, stored at the target repository. A preferred form of authorization is a token, thereby eliminating the need to share sensitive credential information such as passwords between the asset creator and a third party user. The token includes data that allows a program at the asset management system 12, the asset management user computer 14, the data management repository 18, and/or the data distribution control system 26 to securely connect and share the asset data such as summary information between each other. Here, the user has no access to the token. Instead, the asset management system 12 uses the token to retrieve that data on behalf of the asset creator, and can list the result for the user. The asset creator can instruct the data distribution control system 26, or the data management repository 18 to generate an access token. The token can be generated automatically, for example, in response to the asset creator authenticating with the data management repository 18.
At block 204, data retrieved with the access token can be shared with one or more third party users. The data retrieved with the access token can be shared with other users on the same device, for example, the asset management user computer 14, or shared among users on different computers.
At block 206, the authorized third party user can access the asset. In doing so, when the user browses the asset, for example, shown in the screenshot 500 of FIG. 5, the user can receive a rendered compact summary corresponding to the URL executed during the browsing session.
Accordingly, the method 200 when performed can permit an asset creator or other user authorized to access source code or other software-related data at a data repository to share a token and the like with a user who does not have direct access to this data, even when this data is stored at another server.
FIG. 3 is a flowchart of a method 300 for controlling a disclosure of restricted electronic data, in accordance with an embodiment. The method 300 can be governed by instructions that are stored in a memory of one or more electronic devices, for example, the asset management system 12, the asset management user computer 14, the data management repository 18, and/or the data distribution control system 26 of FIG. 1.
At block 302, a link can be provided from an asset to a resource in a target repository, for example, a test data management repository. For example, an asset creator can select a uniform resource locator (URL) that points to a resource at the target data repository 18 related to the asset. In one embodiment, the resource can be information related to defects at a change management repository. In another embodiment, the resource can be a requirement managed at a requirements repository. In another embodiment, the resource can be at a test repository that includes test plans and the like. In another embodiment, the resource can information related to one or more builds, for example, build results generated from assets in the asset management system 12 provided at the target data repository 18. The abovementioned repositories and/or other libraries or data storage facilities, can include asset-related data that provides additional data and traceability to software artifacts or assets to be shared, reused, and or like.
At block 304, a pre-condition arises where the asset management system 12 and the target data repository 18 established a trust domain. An asset creator can authenticate with the target data repository 18. In an embodiment, the oAuth open standard for authorization can be used to authenticate and/or authorize the asset creator with respect to the target data repository 18. An authorization technique such as the open authentication, or oAuth, protocol, can be applied, allowing an asset creator to authenticate with a target repository in a manner that obviates the need for the asset creator to share credentials such as a password.
At block 306, an access token can be provided to the asset management system 12 by the target data repository 18 using the data distribution control system 26. The token is generated by 18 and can only be used by the asset management system 12 for that particular identified resource in the target data repository 18. The token can be constructed to limit the information accessible by a third party user, for example, according to user-defined requirements.
At block 308, a third party user can access the asset. In doing so, the user can browse for data related to the asset by selecting or hovering on the link that provides asset traceability, for example, by attempting to access data at the data repository 18 that is related to the asset such as a test plan.
At block 310, the data distribution control system 26 can process the token, and data related to the oAuth protocol, to render a compact summary rendering for the URL selected by the user, who is authorized on behalf of the asset creator's permissions to receive the summary information.
FIG. 4 illustrates data flow paths between elements of a system that authorize users to share data, in accordance with an embodiment. The system can include an asset creation device 42, a target repository 18, a third party user device 46, an asset management system 12, and/or a data distribution control system 26.
At step 402, an asset creator creates an asset.
At step 404, the asset creator creates a link to a resource at the target repository 18. The asset creator can select at the asset creation device 42 a URL to the resource at the target repository 18.
At step 406, the data distribution control system 26 can manage the authentication of the asset creation device 42 with the target repository 18, for example, to create the link.
At step 408, the target repository 18 can provide the asset management system 12, for example, via the data distribution control system 26, an access token, so that the asset management system 12 can access the resource at the target repository 18 in the future. The data distribution control system 26 and/or the asset management system 12 can store the access token and/or the link information, for example, a URL to which the summary information relates. In this manner, a user can grant a third party user access to information stored with another service provider, without sharing sensitive credentials, and without sharing the full extent of their asset data.
At step 410, a third party user accesses, from a third party user device 46, the asset at the asset management system 12.
At step 412, the asset management system 12, or the data distribution control system 26 processes the access token. At step 416, the asset management system 12 outputs the asset-related data, for example, listing the data provided at step 414 from the target repository 18 according to the selected URL.
FIG. 6 is a flowchart of a method 600 for responding to a token expiration, in accordance with an embodiment. The method 600 can be applied in scenarios where a token expires or where a user wishes to expire a token for security reasons. The method 600 can be governed by instructions that are stored in a memory of one or more electronic devices, for example, the asset management system 12, the asset management user computer 14, the data management repository 18, and/or the data distribution control system 26 of FIG. 1.
At block 602, a user is notified when a token expires. The user can be an asset creator or owner. A token can expire automatically, for example, after predetermined time period or number of accesses. A token can alternatively expire according to a user request. The asset creator 14 can receive a notification of a token expiration via mail, short message (SMS), or other electronic communication.
At block 604, the user can access the asset management system 12, or, more specifically, access an asset.
At block 606, the asset management system 12 redirects user to a target repository 18 where the user's credentials can provided, for example, name, identification, or other security information.
At block 608, a new authorization token can be generated in response to a query for the user's credentials at the target repository 18. The new authorization token can be sent from the target repository 18 to the asset management system 12. Other methods described herein can be applied to process the new token, for example, for authentication.
At block 610, the asset management system 12 can store the new token, for example, to be used by third party users when accessing the corresponding asset.
