I want to use PKI public and private encryption for authentication to allow for a more streamlined and secure application access control system. Any help in the generation of certificate and authentication will be useful. One more question, can i use System.Security.Cryptography.X509Certificates class for the same?
View 1 RepliesI am developing and application in vb.net winxp+ (windows xp upwards). The application has to receive backup data from clients software located at different pc over the Internet. but am concerned about security of this application on the Internet. what would be the best way to implement security in vb.net 2008 to make sure that the data is not sniffed or interfere with?
am thinking of encrypting the data before sending, saving it that way until it need to be viewed before decrypting. what type of encryption would you suggest? Is there any other way you would suggest this data be sent?

View 2 RepliesThrough COM, one can potentially gain absolute control over a target system. For example: using javascript's ActiveXObject object in IE, one can create certain objects which were designed to have direct access or interaction with system properties and files.One would think common sense dictates users disable ActiveX features in IE immediately after installing the browser to ensure their system is protected while surfing the net, or at least paying close attention to which websites they permit. But, I doubt many average PC users know how or why to do this, or just get tired of mirco-managing it over time. I think any PC user or admin my COM class caters to would greatly appreciate not having to deal with that. Thankfully it looks like IE versions come packaged with ActiveX disabled by default nowadays.
I've built a very versatile COM class library in VB. I didn't intend for it to be callable from any website, but that feature is just part of the COM platform. I'd like to prevent the library from being called from IE unless the website is on a white-listed domain to proactively protect the user (and ultimately their entire intranet) from harm from malicious websites. What would be the best method in VB.Net to tell which application called my DLL, to be able to tell if it was called from any command or process originating from IE? And, what domain called my dll? System.Environment.GetCommandLineArgs()(0) gets me the calling application path. With this info, I can compare it to a black/white-list of applications.
I have built a MVC website on IIS6. I used the built-in ASP.NET Security without Membership, just the way it was implemented in the template solution. It is easy to secure a contoller or action, but now I need to expose the user management to an admin logged into the site. I understand that the builtin ASP controls for doing this are not "best practice" and are a dog to get working. So what is the best practice for offering user management through a ASP.NET MVC application?
I considered using the Entity Framework and wireing it up to the myriad of stored procs. but that seems awkward. I see options for AccountMembershipService and FormsAuthenticationService. That is what the existing project account controller uses. But, I am not fimilliar with either.I can't help but think that this should have already been there from the project template. This is a fundamental part of any website and you were given 15%, why not the rest?
i created the following ActionFilterAttribute to check if a user is granted access to a page. I also created two custom Exceptions to handle different scenarios: NotLoggedInException and InsufficientPrivilegeException.
[Code]...
Where do I catch the exceptions to for instance redirect users if not authorized?Should I perhaps use the SiteMap authorization somewhere else instead of using the ActionFilterAttribute and throwing Exceptions..?
note: as you can see I'm using a custom class for BLL.Page. This is a ORM page which has Role based security stored in the database. SiteMap is also populated based on this data

View 1 RepliesI want to add a feature to my trial version of the application. After first activation, I want to make it limited to 90 days. But I am concerned about user's changing the date of system hence deceiving my application. Is there any possibility to make it fool proof in a way that even if user takes the calender back, application expires after 90 days of first activation? First activation date has been saved in the database.
View 2 RepliesOut of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.

I am writing a small visual basic application to install clean up tools quickly on any machines that we need to work on here at my workplace. I am using 4-5 cleanup programs that I have packaged into MSI's and have batch scripts that I am calling in my visual basic application to run them as silent installs. However, because I am doing the silent installs, windows always pops up with the "open file - security warning" and I have to click run for each individual program. I am wondering how to get around this from my end within the application. I know it can be disabled in windows but I am not wanting to have to go through a process on every machine that I run this program on. I would like to find a fix on the back end in my script.
View 2 RepliesI have a Visual Basic.Net Windows Forms application to which I am considering adding the WebBrowser control. I'm assuming that the PC's on which this application will ultimately be deployed/installed will have the latest Windows (XP, Vista, or 7) updates, a firewall, and an Internet security suite installed/running.
With this deployment environment in mind, does the WebBrowser control make my application or the deployment PC vulnerable to any significant security risks? Are there any programming issues that should be addressed to eliminate potential security risks when using the WebBrowser control?

We have a web app that is using forms security.One of the options includes the ability to print an html page to PDF. We're currently evaluating different products like PdfMetamorphosis, but I believe all of them will have this issue.The client makes a request for the pdf by clicking a link button. The code for the button instantiates the PDF builder and passes it a url to convert. However, the URL is behind our forms authentication. Which means that the resulting PDF is nothing but a login page.
Unfortunately, we need the user information in order to verify acccess to the printed page (among other reasons). Which means I can't just allow access to everyone to that folder.So I need one of three possible solutions.
1) I need a way to give the PdfMetamorphosis component the authorization ticket to pass on in it's request.
2) I need an html to pdf component that will do this.
3) Something else?
I don't think the first one is possible and I haven't been able to find a html to pdf component that takes this into consideration.

View 1 RepliesI can use the c110 cam and one of the 270 versions at same time to get two seperate displays but when I try to usetwo of the 270 cams at same time which both show in device manager, I get "camera in use by another application" even though there are two cams (270's)and I reference them both seperately from a populated combo box containig all media devices present.will need to use all of the same type of cam for this app which will have from 4 to 16 or more cameras viewing and or recording at the same time. If there were 16 slightly different versions of the same cam which would give me different drivers, It would be fine but as you can probably imagine, not acceptable.

I'm working with vb.net in Visual Studio 2010, I have a method which writes entries in eventlog, this work fine in Windows XP but did not in Windows 7, here it throws a security exception.I allready know that this problem is because the user who exectues this assembly does not have permissions to write the registry, so my question is if does not exist some way to give permissions on the fly, something like declarative permissions or something
