By Default, ASP.NET does not allow HTML tags to be sent to server via client side due to security reason. Which property needs to be set that allows HTML tags to be processed by server?

  
ValidateRequest Property needs to be set to false. By default it's true so it does not allow unencoded HTML tags to be processed at server. It can be set at page level or at application level via web.config. (More...)

ASP.NET Security Fundamental Operations

  
Security in the context of ASP.NET application involves 3 fundamental operations [1,4,5]:
. Authentication: the process of validating the identity of a user to allow or deny a request [4,9,10]. This involves accepting credentials (e.g. username and password) from the users and validating it against a designated authority. After the identity is verified and validated, the user is considered to be legal and the resource request is fulfilled. Future request from the same user ideally are not subject to the authentication process until the user logs out of the web application.
. Authorization: the process of ensuring that users with valid identity are allowed to access specific resources.
. Impersonation: this process enables an application to ensure the identity of the user, and in turn make request to the other resources. Access to resources will be granted or denied based on the identity that is being impersonated. In other words, impersonation enables a server process to run using the security credentials of the client [6,9]. Thus, the ASP.NET applications are capable to execute the identity of client on whose behalf they are operating.
Since there are a lot of ASP.NET security features to cover, this paper will only focus on authentication in ASP.NET.

Difference of ASP and ASP.NET Security Flow

  
The security flow for ASP.NET page request is different from the classic ASP security flow. In ASP, IIS impersonates the authenticated user by default, and in ASP.NET, the developer has more control over configuring security at different level [2].

What is CODE Access security?

  
CAS is part of .NET security model that determines whether or not a piece of code is allowed to run and what resources it can use while running. Example CAS will allow an application to read but not to write and delete a file or a resource from a folder. (More...)

What is CODE Access security?

  
Code Access Security (CAS), in the Microsoft .NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions.

It performs following function
1. Defines permissions and permission sets that represent the right to access various system resources.
2. Enables administrators to configure security policy by associating sets of permissions with groups of code (code groups).
3. Enables code to request the permissions it requires in order to run, as well as the permissions that would be useful to have, and specifies which permissions the code must never have.
4. Grants permissions to each assembly that is loaded, based on the permissions requested by the code and on the operations permitted by security policy.
5. Enables code to demand that its callers have specific permissions.
6. Enables code to demand that its callers possess a digital signature, thus allowing only callers from a particular organization or site to call the protected code.
7. Enforces restrictions on code at run time by comparing the granted permissions of every caller on the call stack to the permissions that callers must have. (More...)
