  • Using ASP.NET Membership Provider with an ACL

    - by geekrutherford
    Up until recently one of my applications has used the membership provider within ASP.NET exclusively. However, it has been proposed that while the currently defined roles are beneficial, security needs to be more granular to restrict both access to certain pages and functionality present within a given page.   Unfortunately, the role based security ASP.NET gives you out of the box falls down in this area. This is not due to a lack of foresight by Microsoft, but rather it was simply not designed for implementing both role based security and any inherent ACL you may define within these roles. Mind you some would say an ACL is independent of the role to which a user belongs and is assigned to the user directly.   The application mentioned here has it's own User object (which encapsulates the membership provider user object as a property) and SQL Server table to store extended information not present in the aspnet_users table. While I could have modified the aspnet membership schema to suit the applications needs, it seemed smarter to simply create a separate table with a foreign key back to the aspnet_users table.   Since I have a separate object to store extended user information, I simply created an ACL object and expose it as a property of my user object.   This is all well and good, but it does not help in regards to the SiteMapProvider and restricting access at the page level based on the users ACL.   The straightforward answer would be to develop some code within the databound event for the menu that checks the page title and has hardcoded logic that dictates a user must have certain permissions turned on. The problem with this approach is that it's HARDCODED!!! If you need to change access to a page you'd need to do a build and go through your normal deployment process....ugh!!!   An alternative method, albeit not perfect, is to utilize the resourceKey property on the SiteMapNodes in the SiteMap file with the name of the required permission to view the page. Within the databound event for your menu you iterate the SiteMapNodes in the menus SiteMapProvider looking for a match at the page level based on title. When a match is detected, you have a switch/case on the SiteMapNodes resourceKey (the name of the ACL permission required). The case for the resourceKey ensures the users ACL permission is turned on and viola!!!   This is noteably not perfect in that it is using the resourceKey in a manner other than intended.  Since the application is not localized, using it in the manner described it not an issue.   Below is a sample SiteMap file with the resourceKey used as the ACL permission identifier:     Below is the ItemDataBound event. This application uses the Telerik Menu control:

  • What is the best way to diagrammatically represent a system threading architecture?

    - by thegreendroid
    I am yet to find the perfect way to diagrammatically represent the overall threading architecture for a system (using UML or otherwise). I am after a diagramming technique that would show all the threads in a given system and how they interact with each other. There are a few similar questions - Drawing Thread Interaction, UML Diagrams of Multithreaded Applications and Intuitive UML Approach to Depict Threads but they don't fully answer my question.

  • A Hot Topic - Profitability and Cost Management

    - by john.orourke(at)oracle.com
    Maybe it's due to the recent recession, or current economic recovery but a hot topic and area of focus for many organizations these days is profitability and cost management.  For most organizations, aggressive cost-cutting and cost management were critical to remaining profitable while top line revenue was flat or shrinking.  However, now we are seeing many organizations taking a more "surgical" approach to profitability and cost management, by accurately allocating revenue and costs to individual product lines, services, customer segments, locations, channels and other lines of business to understand which ones are truly profitable and which ones are not.  Based on these insights, managers can make more informed decisions about which products or services to invest in or retire, how to price their products or services for different customer segments, and where to focus their marketing and customer service resources. The most common industries where this product, service and customer-focused costing and profitability analysis is being adopted include financial services, consumer packaged goods, retail and manufacturing.  However we are seeing adoption of profitability and cost management applications in other industries and use cases.  Here are a few examples: Telecommunications Industry:  Network Costing and Management to identify the most cost effective and/or profitable network areas, to optimize existing resources, infrastructure and network capacity.  Regulatory Cost Accounting to perform more accurate allocations of revenue and costs across services and customer segments, improve ability to set billing rates for future periods, for various products and customer segments and more easily develop analysis needed for rate case proposals. Healthcare Insurance:  Visually, justifiable Medical Loss Ratio results, better knowledge of the cost to service healthcare plans and members, accurate understanding of member segment and plan profitability, improved marketing programs through better member segmentation. Public Sector:  Statutory / Regulatory Compliance:  A variety of statutory and regulatory documents state explicitly or implicitly that the use of government resources must be properly tracked and tied to performance goals.  Managerial costing methods implemented through Cost Management applications provide unparalleled visibility into costs and shared services usage throughout a Public Sector agency. Funding Support:  Regulations require public sector funding requests to be evaluated based upon the ability to achieve performance goals against the associated cost.   Improved visibility and understanding of costs of different programs/services means that organizations can demonstrably monitor performance and the associated resource costs improve the chances of having their funding requests granted. Profitability and Cost Management is one of the fastest-growing solution areas in Oracle's Enterprise Performance Management product line and we are seeing a growing number of customer successes across geographies and industries.  Listed below are just a few examples.  Here's a link to the replay from a recent webcast on this topic which featured Schroders Plc, a UK-based Financial Services company: http://www.oracle.com/go/?&Src=7011668&Act=168&pcode=WWMK10037859MPP043 Here's a link to a case study on Shenhua Guohua Power in China: http://www.oracle.com/us/corporate/customers/shenhua-snapshot-159574.pdf Here's a link to information on Oracle's web site about our profitability and cost management solutions: http://www.oracle.com/us/solutions/ent-performance-bi/performance-management/profitability-cost-mgmt/index.html

  • Applying Quotas Across all My Sites

    - by Bil Simser
    Just a quick snippet this morning. If you need to apply a new quota template to all users My Sites here's a quick script to do it. Changing an existing quota is fine but if you're migrating users from another system or you just want to up everyone's storage a bit here's what you do. Create a new quota template. This is found in Central Admin under Application Management | Site Collections | Specify quota templates. There's already a default "Individual Quota" created you might want to create your own or have a special one for your users Open up the PowerShell Management Console and enter "Get-SPWebApplication". This will list all your web applications on the farm.  To apply it to all My Sites (each site is a site collection of its own) run this script below. .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: $webapps = Get-SPWebApplication; 2:   3: $webapp = $webapps[4]; 4:   5: foreach ($site in $webapp.Sites) { 6: Set-SPSite -Identity $site.url -QuotaTemplate "Your Quota Template" 7: } The first line gets all the web applications on the server. In our case, the forth one is the mysite web app (yours will probably be a different number). Just run Get-SPWebApplication from the console to figure out which one to use. You could get fancy and pipe the name to find it but I'm too lazy for that.Then we loop through all the sites on the list using the $site.url property and pass it to the Set-SPSite cmdlet and specify the name of the our custom QuotaTemplate.Easy. Now all users are updated with the new quota template.

  • Does 3d modeling software *choice used during asset creation affect performance at runtime

    - by user134143
    Does software used to create 3d assets (for game development specifically) have an impact on the efficiency of the program? In other words, is it possible to reduce the operating footprint of an application merely by utilizing alternative development software during production of 3d assets? If you use two different applications to create a 3 dimensional image of a box, can one of them result in better performance if aspects of the image are identical? I am attempting to get the information I need without causing unnecessary debate over specific software choice.

  • Projected Results

    - by Sylvie MacKenzie, PMP
    Excerpt from PROFIT - ORACLE - by Monica Mehta Yasser Mahmud has seen a revolution in project management over the past decade. During that time, the former Primavera product strategist (who joined Oracle when his company was acquired in 2008) has not only observed a transformation in the way IT systems support corporate projects but the role project portfolio management (PPM) plays in the enterprise. “15 years ago project management was the domain of project management office (PMO),” Mahmud recalls of earlier days. “But over the course of the past decade, we've seen it transform into a mission critical enterprise discipline, that has made Primavera indispensable in the board room. Now, as a senior manager, a board member, or a C-level executive you have direct and complete visibility into what’s kind of going on in the organization—at a level of detail that you're going to consume that information.” Now serving as Oracle’s vice president of product strategy and industry marketing, Mahmud shares his thoughts on how Oracle’s Primavera solutions have evolved and how best-in-class project portfolio management systems can help businesses stay competitive. Profit: What do you feel are the market dynamics that are changing project management today? Mahmud: First, the data explosion. We're generating data at twice the rate at which we can actually store it. The same concept applies for project-intensive organizations. A lot of data is gathered, but what are we really doing with it? Are we turning data into insight? Are we using that insight and turning it into foresight with analytics tools? This is a key driver that will separate the very good companies—the very competitive companies—from those that are not as competitive. Another trend is centered on the explosion of mobile computing. By the year 2013, an estimated 35 percent of the world’s workforce is going to be mobile. That’s one billion people. So the question is not if you're going to go mobile, it’s how fast you are going to go mobile. What kind of impact does that have on how the workforce participates in projects? What worked ten to fifteen years ago is not going to work today. It requires a real rethink around the interfaces and how data is actually presented. Profit: What is the role of project management in this new landscape? Mahmud: We recently conducted a PPM study with the Economist Intelligence Unit centered to determine how important project management is considered within organizations. Our target was primarily CFOs, CIOs, and senior managers and we discovered that while 95 percent of participants believed it critical to their business, only six percent were confident that projects were delivered on time and on budget. That’s a huge gap. Most organizations are looking for efficiency, especially in these volatile financial times. But senior management can’t keep track of every project in a large organization. As a result, executives are attempting to inventory the work being conducted under their watch. What is often needed is a very high-level assessment conducted at the board level to say, “Here are the 50 initiatives that we have underway. How do they line up with our strategic drivers?” This line of questioning can provide early warning that work and strategy are out of alignment; finding the gap between what the business needs to do and the actual performance scorecard. That’s low-hanging fruit for any executive looking to increase efficiency and save money. But it can only be obtained through proper assessment of existing projects—and you need a project system of record to get that done. Over the next decade or so, project management is going to transform into holistic work management. Business leaders will want make sure key projects align with corporate strategy, but also the ability to drill down into daily activity and smaller projects to make sure they line up as well. Keeping employees from working on tasks—even for a few hours—that don’t line up with corporate goals will, in many ways, become a competitive differentiator. Profit: How do all of these market challenges and shifting trends impact Oracle’s Primavera solutions and meeting customers’ needs? Mahmud: For Primavera, it’s a transformation from being a project management application to a PPM system in the enterprise. Also making that system a mission-critical application by connecting to other key applications within the ecosystem, such as the enterprise resource planning (ERP), supply chain, and CRM systems. Analytics have also become a huge component. Business analytics have made Oracle’s Primavera applications pertinent in the boardroom. Now, as a senior manager, a board member, a CXO, CIO, or CEO, you have direct visibility into what’s going on in the organization at a level that you're able to consume that information. In addition, all of this information pairs up really well with your financials and other data. Certainly, when you're an Oracle shop, you have that visibility that you didn’t have before from a project execution perspective. Profit: What new strategies and tools are being implemented to create a more efficient workplace for users? Mahmud: We believe very strongly that just because you call something an enterprise project portfolio management system doesn’t make it so—you have to get people to want to participate in the system. This can’t be mandated down from the top. It simply doesn’t work that way. A truly adoptable solution is one that makes it super easy for all types users to participate, by providing them interfaces where they live. Keeping that in mind, a major area of development has been alternative user interfaces. This is increasingly resulting in the creation of lighter weight, targeted interfaces such as iOS applications, and smartphones interfaces such as for iPhone and Android platform. Profit: How does this translate into the development of Oracle’s Primavera solutions? Mahmud: Let me give you a few examples. We recently announced the launch of our Primavera P6 Team Member application, which is a native iOS application for the iPhone. This interface makes it easier for team members to do their jobs quickly and effectively. Similarly, we introduced the Primavera analytics application, which can be consumed via mobile devices, and when married with Oracle Spatial capabilities, users can get a geographical view of what’s going on and which projects are occurring in various locations around the world. Lastly, we introduced advanced email integration that allows project team members to status work via E-mail. This functionality leverages the fact that users are in E-mail system throughout the day and allows them to status their work without the need to launch the Primavera application. It comes back to a mantra: provide as many alternative user interfaces as possible, so you can give people the ability to work, to participate, to raise issues, to create projects, in the places where they live. Do it in such a way that it’s non-intrusive, do it in such a way that it’s easy and intuitive and they can get it done in a short amount of time. If you do that, workers can get back to doing what they're actually getting paid for.

  • Token based Authentication and Claims for Restful Services

    - by Your DisplayName here!
    WIF as it exists today is optimized for web applications (passive/WS-Federation) and SOAP based services (active/WS-Trust). While there is limited support for WCF WebServiceHost based services (for standard credential types like Windows and Basic), there is no ready to use plumbing for RESTful services that do authentication based on tokens. This is not an oversight from the WIF team, but the REST services security world is currently rapidly changing – and that’s by design. There are a number of intermediate solutions, emerging protocols and token types, as well as some already deprecated ones. So it didn’t make sense to bake that into the core feature set of WIF. But after all, the F in WIF stands for Foundation. So just like the WIF APIs integrate tokens and claims into other hosts, this is also (easily) possible with RESTful services. Here’s how. HTTP Services and Authentication Unlike SOAP services, in the REST world there is no (over) specified security framework like WS-Security. Instead standard HTTP means are used to transmit credentials and SSL is used to secure the transport and data in transit. For most cases the HTTP Authorize header is used to transmit the security token (this can be as simple as a username/password up to issued tokens of some sort). The Authorize header consists of the actual credential (consider this opaque from a transport perspective) as well as a scheme. The scheme is some string that gives the service a hint what type of credential was used (e.g. Basic for basic authentication credentials). HTTP also includes a way to advertise the right credential type back to the client, for this the WWW-Authenticate response header is used. So for token based authentication, the service would simply need to read the incoming Authorization header, extract the token, parse and validate it. After the token has been validated, you also typically want some sort of client identity representation based on the incoming token. This is regardless of how technology-wise the actual service was built. In ASP.NET (MVC) you could use an HttpModule or an ActionFilter. In (todays) WCF, you would use the ServiceAuthorizationManager infrastructure. The nice thing about using WCF’ native extensibility points is that you get self-hosting for free. This is where WIF comes into play. WIF has ready to use infrastructure built-in that just need to be plugged into the corresponding hosting environment: Representation of identity based on claims. This is a very natural way of translating a security token (and again I mean this in the widest sense – could be also a username/password) into something our applications can work with. Infrastructure to convert tokens into claims (called security token handler) Claims transformation Claims-based authorization So much for the theory. In the next post I will show you how to implement that for WCF – including full source code and samples. (Wanna learn more about federation, WIF, claims, tokens etc.? Click here.)
