You are developing an ASP.NET MVC application that uses forms authentication. The 

application uses SQL queries that display customer order data. 

Logs show there have been several malicious attacks against the servers. 

You need to prevent all SQL injection attacks from malicious users against the application. 

How should you secure the queries? 

A. Check the input against patterns seen in the logs and other records. 

B. Escape single quotes and apostrophes on all string-based input parameters. 

C. Implement parameterization of all input strings. 

D. Filter out prohibited words in the input submitted by the users. 

Answer:

Explanation: SQL Injection Prevention, Defense Option 1: Prepared Statements (Parameterized Queries) The use of prepared statements (aka parameterized queries) is how all developers should first be taught how to write database queries. They are simple to write, and easier to understand than dynamic queries. Parameterized queries force the developer to first define all the SQL code, and then pass in each parameter to the query later. This coding style allows the database to distinguish between code and data, regardless of what user input is supplied. 

Prepared statements ensure that an attacker is not able to change the intent of a query, even if SQL commands are inserted by an attacker.

Q69. - (Topic 2) 

You are designing a Windows Communication Foundation (WCF) service that uses the Product class. 

You need to update the class to meet the storage requirement. 

What should you do? (Each correct answer presents part of the solution. Choose all that apply.) 

A. Mark the Product class with the DataContract attribute. 

B. Mark the public members of the Product class with the DataContractFormat attribute. 

C. Mark the Product class with the CollectionDataContract attribute. 

D. Mark the public members of the Product class with the DataMember attribute. 

Answer: A,D 

Explanation: So as of .NET 3.5 SP1, you don't have to add data contract or data member 

attributes anymore - if you don't then the data contract serializer will serialize all public 

properties on your class, just like the XML serializer would. 

HOWEVER: by not adding those attributes, you lose a lot of useful capabilities: 

. without [DataContract], you cannot define an XML namespace for your data to live 

in . without [DataMember], you cannot serialize non-public properties or fields . without [DataMember], you cannot define an order of serialization (Order=) and the 

DCS will serialize all properties alphabetically . without [DataMember], you cannot define a different name for your property (Name=) . without [DataMember], you cannot define things like IsRequired= or other useful attributes . without [DataMember], you cannot leave out certain public properties - all public properties will be serialized by the DCS
