  • Security-Active Application in background-Does it store image of current screen

    - by user1509593
    Is this a probable security flaw. A user in public (lets say Starbucks) tries to log in to iOS application. He enters user id and password [Password is hidden using xxxxxxxx (not exposed)] and a call comes in or he presses home and the application goes to background. a) Does iOS store an image of current screen b) A malicious hacker with intent takes control of the device. Can he read the password ? Do we have to clear out sensitive information while going to background

  • Thread pool stack security issue

    - by elmatador
    In a naive implementation of a thread pool, can a piece of code that is being executed read the data left by some previous code on the stack (if it was running on the same thread instance)? Also, are there any other inherent security issues connected to thread pools?

  • Security Resources Defining, Static/Dynamic

    - by mmontalvo
    I am implementing a simple(hopefully) security manager within an application. Is it better to have predefined(static) roles, custom roles(dynamic)? I am leaning more towards dynamic groups or roles only because then it would not require a redeploy to update the system. Also, what would be the best approach to define resources in general? The application has a database that can hold either the static or dynamic values.

  • What is New in ASP.NET 4.0 Code Access Security

    - by HosamKamel
    ASP.NET Code Access Security (CAS) is a feature that helps protect server applications on hosting multiple Web sites, ASP.NET lets you assign a configurable trust level that corresponds to a predefined set of permissions. ASP.NET has predefined ASP.NET Trust Levels and Policy Files that you can assign to applications, you also can assign custom trust level and policy files. Most web hosting companies run ASP.NET applications in Medium Trust to prevent that one website affect or harm another site etc. As .NET Framework's Code Access Security model has evolved, ASP.NET 4.0 Code Access Security also has introduced several changes and improvements.   A Full post addresses the new changes in ASP.NET 4.0 is published at Asp.Net QA Team Here http://weblogs.asp.net/asptest/archive/2010/04/23/what-is-new-in-asp-net-4-0-code-access-security.aspx

  • Oracle Database Security Protecting the Oracle IRM Schema

    - by Simon Thorpe
    Acquiring the Information Rights Management technology in 2006 was part of Oracle's strategic security vision and IRM compliments nicely the overall Oracle security set of solutions. A year ago I spoke about how Oracle has solutions that can help companies protect information throughout its entire life cycle. With our acquisition of Sun this set of solutions has solidified and has even extended down to the operating system and hardware level. Oracle can now offer customers technology that protects their data from the disk, through the database to documents on the desktop! With the recent release of Oracle IRM 11g I was tasked to configure demonstration and evaluation environments and I thought it would make a nice story to leverage some of the security features in the latest release of the Oracle Database. After building these environments I thought I would put together a simple video demonstrating how both Database Advanced Security and Information Rights Management combined can provide a very secure platform for protecting your information. Have a look at the following which highlights these database security options.Transparent Data Encryption protecting the communication from the Oracle IRM server to the Database server. Encryption techniques provide confidentiality and integrity of the data passing to and from the IRM service on the back end. Transparent Data Encryption protecting the Oracle IRM database schema. Encryption is used to provide confidentiality of the IRM data whilst it resides at rest in the database table space. Database Vault is used to ensure only the Oracle IRM service has access to query and update the information that resides in the database. This is an excellent method of ensuring that database administrators cannot look at or make changes to the Oracle IRM database whilst retaining their ability to administrate the database. The last thing you want after deploying an IRM solution is for a curious or unhappy DBA to run a query that grants them rights to your company financial data or documents pertaining to a merger or acquisition.

  • Best way to fix security problems caused by windows updates?

    - by Chris Lively
    I have a laptop running Windows 7 32-bit. Last nights security updates caused my logitech mouse to stop working (specifically, it caused several USB ports to stop altogether). After reviewing the system event log I found that the IPBusEnum component was failing due to an activation security error. A little more research and I found that this was caused by the TrustedInstaller replacing the security permissions on those keys and generally mucking them up. To fix this I had to open regedit, take ownership of ALL the keys related to IPBusEnum and force it to use the inherited permissions from the tree. Is there a better way to fix this when MS screws up the updates? I would hate to have to walk around to a number of machines and manually fix the registry key security settings.

  • Difference between $ and # in ADF/JSF/JSP

    - by pavan.pvj
    Found this one interesting. So, picked it from one of the books and posting here.JSP 2.1 and JSF 1.2 - both of them use a unified Expression language. One major and the most obvious difference is between $ and #. JSP 2.1 uses $ and JSF 1.2 uses # in an EL. $ - immediate evaluation# - deferred evaluation$ - $ syntax executes expressions eagerly/immediately, which means that the result is returned immediately when the page renders.# - # syntax defers the expression evaluation to a point defined by the implementing technology. In general, JSF uses deferred EL evaluation because of its multiple lifecycle phases in which events are handled. To ensure the model is prepared before the values are accessed by EL, it must defer EL evaluation until the appropriate point in the life cycle.Note: This is picked up from Oracle Fusion Developer Guide (ISBN: 9780071622547). There is also a very good article here:http://java.sun.com/products/jsp/reference/techart/unifiedEL.html
