User input remains the primary cause of vulnerabilities in most of the web applications. The process of screening the user entered input for malicious content is known as input validation. Input validation is a proactive step taken to avoid falling prey to commonly known vulnerabilities. Although the need for performing good input validation is fairly obvious to everyone in the field, not many people do a good job at the same.
The Validator.NET application was designed to enable developers to programmatically determine user input locations that could be potentially exploited by hackers and provides proactive steps to build data validation routines which are loaded into a protection module. The tool helps eliminate common vulnerabilities such as SQL Injection and Cross-Site Scripting.
The need for input validation originates from the premonition that all input is evil. Hackers and security professionals have managed to compromise the web applications time and again because the developers followed no strategy to defend their web applications. In a race to check for malicious content the developers always were left behind because the hackers managed to encode their malicious content in innocuous looking input.
Writing code to check for every input field was often taxing, inefficient, incomplete and not through. For the same reasons Microsoft provided extensive validation framework in ASP.NET. The aim was to help developers perform data validation routines faster and in a more efficient manner. Even with the presence of these validators, data validations techniques are no where near acceptable level.
Lack of security awareness among developers is part of the reason for insufficient data validation techniques in most of the existing applications. The result is that we have many production environments which do not have acceptable data validation mechanisms. The cost of making code fixes in these applications is often very high and hence is not the most effective solution.
Buffer overflows, SQL inject, Cross-Site Scripting and Denial of service are just a few of the most common vulnerabilities caused by bad input validation techniques.
If proper data validations techniques are not implemented then there always exists the possibility of falling prey to one or more of the above mentioned vulnerabilities.
The need was to develop a cost effective input validation solution for the large number .NET of web application that do not have acceptable validation routines. The solution was required to have minimal code changes and should be completely configurable to tailor the needs of every web application. Considering the problems at hand, Foundstone devised the Validator.NET tool.
Validator.NET For PC (Updated 2022)
Foundstone VNUC is an ASP.NET application that enables to create web pages with lightweight validation in C#. It helps web developers perform cross site scripting and SQL injection validation. The tool also helps to validate user entered data when it is posted back to the server.
VNUC uses the W3C Schema validation tool suite to help validate user entered data and reduce the need of regular code validation routines. The tool enables developers to perform data validation in a simple, safe and efficient manner.
The Validator.NET tool enables to create a quick validator for a single web page, a folder or the entire web application. The developers can also use the tool to create validation routines for common scenarios like numeric fields, email fields and single select fields. The tool can perform additional checks like validation of maximum and minimum numbers, maximum number of characters, minimum password length, improper date format and for non-numeric fields like zipcode.
The following security checks are performed at the time of validation:
The Tool provides a simple W3C validator which is efficient and very helpful in validating the data. This validator supports the following fields:
The W3C validator also makes use of reflection-based scanning to check for the most common web vulnerabilities like SQL Injection, Cross-Site Scripting and XSS. Validation checks for duplicate values, null values, empty strings, improper value values like script/address, any values that are empty (null, 0, false, false, 0) and the range of values (e.g., 0-100).
In addition to the above checks, the tool provides additional security features like support for max and min number values, password restriction, zipcodes etc.
The user enters data in the form of a web page. This page is rendered to a text file containing the user input. The user input is then parsed using an intermediate language called the B3ISAS description language (B3ISAS is a light-weight, XML based language).
The parsed XML is then validated using the w3c validator. The validator performs the validation in two ways.
a) The validator parses the input from the web page and validates it. This is done once when the validation is initiated (either by a button click or by the browser submission).
b) The validator uses the B3ISAS descriptions to perform full-scan for various potential web vulnerabilities.
When the validator finds a W3
Validator.NET Crack + With License Code
The validator.net is a free tool that discovers vulnerable input fields within an application and warns its returns a recommendation of what to do to protect the application against malicious input. It is developed by Foundstone which is a New Zealand based software development company. Its primary objective is to enhance the overall security of.NET applications.
Validator.NET uses a set of rules which are specific to a particular application. These rules enable the tool to scan the code base for all possible input sites. The tool generates a list of all the input fields present in the application which are vulnerable to most of the common input validation. The recommended input validations can be done using data attributes which are declared in every input field in the application.
Validator.NET also provides the developer with an option to write custom validations for the fields which do not have any data annotations. The tool will then check if the input is conforms to the validations that are defined by the developer.
The tool will provide the developer the correct way to protect the data present in the particular input field. It will list the input fields present in the application which are vulnerable to SQL injection, Cross-Site Scripting and Denial of service.
Validator.NET provides the developer with a visual web application where he or she can customize the rules for a particular input field. The developer can simply add or modify the validations for that particular input field. The result is that the tool will provide real time protection of the input field.
The developer can prevent the users from entering the inputs which are not valid by simply disabling the input field. The result is that the tool will prevent data in SQL injection attacks.
Validator.NET will provide the developer with the set of data validation attributes which need to be included in the input field to make it compliant to the data validation rules. For example the data annotation could be like this:
[Required(ErrorMessage=”Required”)]
But Validator.NET can check for the existence of data annotationannotation and provide the developer the correct set of data annotation.
Validator.NET also provides the developer with an option to write custom validation rules that will be loaded in the tool. The custom validations can be used for complex validation scenarios that are not possible with the data annotation. This is possible because the custom validations are first tested and then loaded into the tool for use.
This is not to say that the custom validations are used for all the applications. For larger applications they

Validator.NET Crack+ [Mac/Win] (Updated 2022)
Foundstone has released an open source tool called the Validator.NET application. The application was developed to fill the gap in the performance and ease of use of the existing application security solutions. The tool provides a comprehensive set of data validation tools. The Validator.NET application can be used to prevent different types of XSS attacks, SQL injection attacks, Cross Site Scripting attacks and file upload attacks.
The two major innovative features of this application are that it is:
1. A free tool provided by Foundstone in the public domain with no restrictions;
2. Can be integrated within the existing development environment without any changes to the code or the application logic.
The next sections describe in detail the two major innovative features of Validator.NET:
1. Public domain with no restrictions, free to use
With the acquisition of open source products from many companies by Foundstone, a number of licenses have been placed on the work and the use of the product. This tool works in the public domain with no restrictions. Not only the binary but the source code to the product is available free of charge. The tools can be used as a stand-alone or integrated into the development environment of the project as required.
The workflow to use this tool is simple and fast:
1. Download the tool from the open source web site.
2. Run the validator application locally.
3. To get a report, browse to the url www.validator.com and you will get the report.
The web server to the validator needs to be in the public domain. The web server should not have any authentication mechanism like the IIS authentication mechanism. While this is not a problem on a production server, it is a requirement if the server is to be used for testing purpose. The app pool to the application server should have the HTTP run as a system process with no authentication mechanism.
We used IIS 7.0 to host the web application.
The tool can be hosted in any IIS application with the HTTP run as a system process and no authentication mechanism. The details of how to host the application are provided on the open source web site. We used the W3 Web Server as the web server with the HTTP run as a system process and no authentication mechanism enabled. We used the iisapp.exe application for hosting the web application.
The tool can be hosted either as a stand alone or as a module in the web server application. We used the standalone form of hosting.

What’s New In Validator.NET?
The Validator.NET is an easy to use data validation tool, which helps developers add input validation features to their web applications. The tool provides a set of rules which can be used to perform validation on the user entered data.
Today Validator.NET includes data validation rules for SQL Injection, Cross-Site Scripting (XSS), Buffer Overflow and Denial of Service.
Examples:
SELECT * FROM tbl_name WHERE ID=1;
SELECT * FROM tbl_name WHERE ID=:id;
SELECT * FROM tbl_name WHERE ID=:id AND (col_name=:value OR col_name=:value2);
SELECT * FROM tbl_name WHERE ID=:id AND (col_name=:value OR col_name=:value2 AND group_name =:group)
While performing data validation the Validator.NET tool produces outcome results that helps the developers complete their tasks faster, effectively and in a more streamlined manner. With the results of the data validation, developers can easily identify all potentially dangerous and vulnerable locations within the applications.
Having the knowledge of the bad input, developers can easily incorporate the data validations at various locations to eliminate risky behaviour. Validation rules can be applied on requests coming from different platforms and browsers. The tool will work on different versions of.NET technologies, including the latest release of ASP.NET.
Validator.NET is a stand alone.NET application. It does not require database access and can be deployed on every web server in your IT infrastructure in order to provide a global approach to input validation. Data validation tool should be installed on the production environment, after which a single change to the web application would be enough to start protecting the application. Validator.NET is completely configurable and can be easily configured to match your unique web application requirements.
Unlike other application that add data validation routines to a web application, Validator.NET comes packaged with a set of default and static data validation rules that help protect your web applications from the common vulnerabilities.
Key Features:
Fast, lightweight, production ready
Configurable rules that helps prevent most of the common web application vulnerabilities
Data validation tools can be integrated with most of the existing technologies in the.NET applications. The tool is designed to suit the latest version of ASP.NET, hence it works with all the latest.NET technologies.
