Preventing SQL injection attacks in ASP.NET

dotnethitman.spaces.live.com — SQL injection can occur when an application uses input to construct dynamic SQL statements or when it uses stored procedures to connect to the database. Conventional security measures, such as the use of SSL and IPSec, do not protect your application from SQL injection attacks. Successful SQL injection attacks enable malicious users to execute commands in an application's database. You should always be reviewing your code to find these or other security vulnerabilities; remember all type of attacks start with some input, and your first line of defense should be input validation using both client-side and server-side validation. read more...

Using Validation Application Block in ASP.NET

dotnethitman.spaces.live.com — Any web page which requires input from the user simply cant allow just any data to be entered because the data might be too long, missing or incorrect. We need to validate the data entered by the users in a number of ways; for example, First Name and Last Name might be required fields and Date of Birth cannot be greater than the current date etc. We can very well use the client side validators provided by ASP.NET like RequiredFieldValidator, CompareValidator or RegularExpressionValidtor but is that really enough? What if JavaScript is disabled by the client? What if we need to validate our business objects? It is often important to validate data several times within the same application. For example, you may need to validate object instances that you: -Generate in separate tiers or components of your application -Retrieve from a cache, a repository, or a third-party data access layer -Receive from a Web Service as an object instance or a set of property values -Reconstruct from existing values, perhaps populating them by copying properties from a similar object or using values retrieved from a database Enter the Enterprise Library with its Validation Application Block. read more...
