Authentication of an ASP.NET Web application

Form authentication is the most commonly used authentication methods of all in ASP.NET programming. Depending on the Client requirement, as a programmer one might want to consider using the SSL throughout the site or at least on the login page. But overall, this approach is not so secure as it sends the User’s credentials to the server in clear context.

Lack of password policy, passing incorrect internal messages to the browser, using cookies and other insecure means to store the Users’ credentials, etc. are the possible deficiencies with decision of authentication policy in ASP.NET programming.

A web application’s authentication in ASP.NET can be further enhanced with the following:
> Password policy… enforcement of a password policy including strong passwords, password expiration, and possibly locking User accounts after some unsuccessful login attempts.
> Hashing of password… if you manage your authentication store, make sure to hash your all the passwords for the system
> Brute Force Attacks… introduction of a random delay of a few seconds on every login attempt will make the brute force attacks impractical to execute

Metadata: Concept in ASP.NET programming

Metadata – typically means the data within the data files. With reference to ASP.NET programming, meta data is the binary information which describes the characteristics of a resource. This information includes the description of the Assembly, data types and members with their security permissions, declarations, implementations, references to other types and members, etc.

In ASP.NET programming, the metadata describes all classes and class members that are defined in the assembly, and the members which the current assembly will call from another assembly. Moreover, the metadata eliminates the need for interface definition language (IDL) files, header files, or any external method of component reference.

During the compilation of any program, both the metadata and MSIL are together wrapped in a Portable Executable files. Now, when the program is running, the JIT compiler of CLR uses the metadata and converts the MSIL into a native code. And when the code is executed, the runtime loads metadata into memory and references it to get the information about the code’s classes, members, inheritance, and so on.

ASP.NET Strong Names

In ASP.NET programming terms, a strong name consists of the assembly's identity — its simple text name, version number, and culture information (if provided) — plus a public key and a digital signature.

In particular, strong names satisfy the following requirements:

They guarantee name uniqueness by relying on unique key pairs. No one can generate the same assembly name that you can, because an assembly generated with one private key has a different name than an assembly generated with another private key.

Strong names protect the version lineage of an assembly for ASP.NET programmers. It can ensure that no one can produce a subsequent version of your assembly. Users can be sure that a version of the assembly they are loading comes from the same publisher that created the version the application was built with.

Strong names provide a strong integrity check. Passing the .NET Framework security checks guarantees that the contents of the assembly have not been changed since it was built. Note, however, that strong names in and of themselves do not imply a level of trust like that provided, for example, by a digital signature and supporting certificate.

Satellite Assembly in ASP.NET Programming

A compiled code library used for deployment, version, and security is known as assembly in ASP.NET programming terms. A single assembly can consist of one or more files. Microsoft’s Visual Studio does not support using different languages in one assembly.

A classic .NET framework assembly contains resources specific to a give programming language. With usage of the satellite assemblies, one can place the resources for different languages in different assemblies. The correct assembly s then loaded into memory only if the User selects to view the application in that language. Overall, the assemblies must contain culture-neutral resources. If as a ASP.NET programmer, you want to localize the assembly, then you should go for satellite assembly.

A process assembly represents a process that will use classes defined in library assemblies. There are basically two types of assemblies: process assemblies (.exe) and library assemblies (.dll).

Common Language Runtime (CLR) in ASP.NET

The Common Language Runtime (CLR) is an execution environment in ASP.NET development simple words. The main function of the CLR is conversion of the managed code into native code and then executes the program accordingly. It works as a layer between the operating system and the applications written in .NET languages that confirms to the Common Language Specifications (CLS).

The managed code compiled when only it is needed, that is it converts the appropriate instructions when each function is called. The Just In Time (JIT) is included in the CLR – it compiles the conversion of the Intermediate language to native code on demand at application run time.

During the execution of the program, the CLR manages memory, thread execution, garbage collection, exception handling, Common Type System (CTS), code safety verifications, and other system services. It is also referred to as a managed environment, because it also controls the interaction of the operating system with the program during the execution of a program.

Data binding in ASP.NET

The process of binding data on the server side control that will then render that data in some form to the Client is known basically as data binding in ASP.NET programming.  The only possible constraint for the data binding are that the server-side control must support a property called DataSource and a method called DataBind().

It works in this way: when you add a data binding to an ASP.NET webform, the Visual Studio .NET adds a data binding expression to the ASPX file. When the webform is requested for the first time, the ASPX file is parsed. The data binding event is fired when the controls databind method is called, and the handlers added by the ASP runtime evaluates the data binding expression and performs the actual data binding.

It we are able to ge the data bindings at run time, we could use reflection to perform 2-way data binding. However, there is no way to get the data bindings at runtime.

Yes, the ASP.NET programmers can add properties to the controls to store the data bindings in order to fix that problem. Although it can be an obstruction to make the code very clear, this option is still open.

Cookies in ASP.NET: Usage & security

In one of the previous blog article, we had explained the general purpose and meaning of using cookies in ASP.NET development. To take the discussion further, let us talk here about the technical ways and options of using cookie and their security.

Following are the most common ways for ASP.NET developers to user the cookies:
> By using HttpCookies class
> By storing multiple values in the same cookie
>By using Response directly

Security:
Security has always been a dicy question for all the ASP.NET developers all the times. They can be easily used by Spyware to track the User’s browsing activities. Cookies can be stolen by hackers too, to gain access to a victim’s web account. Even cookies are not software and they cannot be programmed like normal executable apps.

Although, they cannot carry viruses and cannot install malware on the host computer.

At SPEC INDIA, our trained team of ASP.NET developers are eager to make very smart and secure use of cookies, thus to ensure the authentication to the browser sessions. It you have any requirement or queries, feel free to drop an email at our id lead@spec-india.com, we will be happy to assist you.

Cookies in ASP.NET: An Introduction

 

 

Cookies are small amounts of text that could be stored on the Client computer system by the browser. They are not software. Cookies are ways to store the data about a website visitors during the time when web server and browser are not connected. Thus, they are basically used to remember the Users between visits. They are particularly small in size, so the ASP.NET developers cannot store more than 4k of information. 

However, the client computers can open the cookie and see the content of a cookie, so it is highly recommended to not to store any passwords here. They are generally used to save User preference information.

Use of Cookies:

• Storing Shopping cart content
• User authentication
• Setting User preferences
• Identification of a User information
  etc.

Database Web Application Development in ASP.NET

Oracle or MS-SQL serve as some effective backend to build database applications in ASP.NET. In this article, we will talk about Oracle in general. Oracle integrates directly with Microsoft ASP.NET in a number of ways:

>  Enabling ASP.NET data access by using ODP.NET

>  Using Oracle developer tools for Visual Studio tools

>  Direct integration with Microsoft ASP.NET controls and services

The databases have always been the core part of the dynamic websites for ASP.NET developers.  From the above 3, I guess the 2^nd one is the easy way comparatively to make the database and the frontend of the website interact with each other.

Initially, the ASP.NET developers should use the available tools to build a web application that retrieves the data from the Oracle database into a data grid. After that, a general login control can be added in order to secure the application by permitting only the authorized web users to access the application and the information. Finally, the developers can create any number of authorized web users using Oracle providers for ASP.NET. And all the information for these created web users will be stored within the Oracle database for checking their authenticity.

At SPEC INDIA, our trained team of ASP.NET professionals are able to make any application or the most complex dynamic websites as per the customized requirements of our Clients. You can always send an email of your requirements at our email contact lead@spec-india.com and we will definitely get back to you on the same with quality results.

Ajax: Introduction and Advantages

Basically, the term AJAX stands for Asynchronous JavaScript and XML. A set of technologies coming under this development environment is referred collectively as AJAX.  It represents a similar concept to the Client-server development, but here the amount of data transferred is minimized over a terminal application by transferring only the necessary data back and forth. Similarly, with AJAX, only the necessart data is transferred back and forth between the Client and the web server. This clear minimizes the network utilization and processing on the Client.

The main technical advantages of AJAX are as listed:

Ø  Minimal data transfer

Ø  AJAX allows asynchronous calls

Ø  Only limited processing on the server

Ø  High responsiveness

Ø  Rapid location of the context of the page

At SPEC INDIA, with the development of ASP.NET applications and websites, our developers make a very smart use of all the AJAX tools. The primary reason as always been to minimize the page loading time and hence to add to the speed of the website functioning.

What makes the ASP.NET websites slow?

With Christmas holidays approaching, almost all the Companies will wish their ASP.NET websites to be at the top of Google rankings, and have the minimal loading times. The speed of the website directly affects bounce ratese, conversion rates, revenue, user satisfaction, SEP and virtually every other business metric worth to be counted.

Here are some of the considerations that the ASP.NET developers should consider always to make the loading time of their webpage as faster as possible:
    Too many HTTP requests
    Minimal Client-side (front-end) processing
    Too many bytes
    Low number of parallel requests (separate query strings)
    Failure to use a global network
    Failure to influence the browser cache/local storage
    Third-party widgets and API integrations
and so on…

At SPEC INDIA, our well-trained team of ASP.NET developers always takes care to avoid these mistakes, because ultimately they hinder in conduction of the marketing activities of the website as a whole. For this, we keep the architecture of the websites very SEO friendly right from the beginning.
