In order to access identity related information, you can run FedUtil. Once you have run FedUtil, your application can
access IClaimsPrincipal and IClaimsIdentity using the standard ASP.NET constructs as shown in the following code
example:
void Page_Load(object sender, EventArgs e)
{
// Cast the Thread.CurrentPrincipal
IClaimsPrincipal icp = Thread.CurrentPrincipal as IClaimsPrincipal;
// Access IClaimsIdentity which contains claims
IClaimsIdentity claimsIdentity = (IClaimsIdentity)icp.Identity;
// Access claims
foreach(Claim claim in claimsIdentity.Claims)
{
}
}

QUESTION 12
You are developing an ASP.NET MVC application.
The application provides a RESTful API for third-party applications. This API updates the information for a contact by
embedding the information in the URL of an HTTP POST.
You need to save the Contact type when third-party applications use the EditContact method.
Which code segment should you use? {Each correct answer presents a complete solution. Choose all that apply.)
A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: BC
Basics of RESTful services:
REST stands for Representational State Transfer, it is a simple stateless architecture that runs over HTTP where each
unique URL is representation of some resource. There are four basic design principles which should be followed when
creating RESTful service:
* Use HTTP methods (verbs) explicitly and in consistent way to interact with resources (Uniform Interface), i.e. to
retrieve a resource use GET, to create a resource use POST, to update a resource use PUT/PATCH, and to remove a
resource use DELETE.Etc.
QUESTION 13
You are developing an ASP.NET MVC application that uses forms authentication. The application uses SQL queries
that display customer order data.
You need to prevent all SQL injection attacks against the application.
How should you secure the queries?
A. Implement parameterization.
B. Pattern check the input.
C. Filter out prohibited words in the input.
D. Escape single quotes on string-based input parameters.
Correct Answer: A
With most development platforms, parameterized statements that work with parameters can be used (sometimes called
placeholders or bind variables) instead of embedding user input in the statement. A placeholder can only store a value
of the given type and not an arbitrary SQL fragment. Hence the SQL injection would simply be treated as a strange (and
probably invalid) parameter value.
