It is not limited to development only. A secured app always involves various layers of security in the framework, web server, configuration and etc.\u00a0 <\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Developing an application using ASP.Net is becoming easier because of the developing technology and the environment. Today, many of the complexities are considered by the framework and it allows the users to focus more on the business value and the application instead of considering the technical aspects.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">But one thing is certain that unless the developers make security one of their prime focus in the early development cycle, the project manager might simply end up with the application that cannot go live without compromising on the safety issues.<\/span><\/p>\n<hr \/>\n<h5 style=\"text-align: justify;\"><span style=\"font-size: 18pt;\"><a href=\"https:\/\/www.idslogic.com\/tips-to-secure-your-asp-net-application\/\"><span style=\"color: #800000;\"><strong>Tips to secure your ASP.NET application<\/strong><\/span><\/a><\/span><\/h5>\n<p><a href=\"https:\/\/www.idslogic.com\/tips-to-secure-your-asp-net-application\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-1535\" src=\"http:\/\/www.idslogic.com\/blog\/wp-content\/uploads\/2018\/04\/secure-your-ASP.NET-application.jpg\" alt=\"\" width=\"1024\" height=\"111\" srcset=\"https:\/\/www.idslogic.com\/blog\/wp-content\/uploads\/2018\/04\/secure-your-ASP.NET-application.jpg 1024w, https:\/\/www.idslogic.com\/blog\/wp-content\/uploads\/2018\/04\/secure-your-ASP.NET-application-300x33.jpg 300w, https:\/\/www.idslogic.com\/blog\/wp-content\/uploads\/2018\/04\/secure-your-ASP.NET-application-768x83.jpg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/p>\n<p><span style=\"font-size: 14pt;\">Implementing security is the first step associated with ASP.Net website development. Fixing the software defect after it is launched would cost up to 15 times more that the cost involved in the development phase. <\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Though securing the application may be a complex task, but it has to be done on a continuous basis. The .NET framework offers reliable features that make it an easy task to secure your web application.<\/span><\/p>\n<hr \/>\n<h6 style=\"text-align: justify;\"><span style=\"color: #003366; font-size: 18pt;\"><strong>Authentication:<\/strong><\/span><\/h6>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">ASP.Net supports various authentication methods, and form authentication is the most commonly used web applications. But the approach is not a secured approach as it sends the user\u2019s credentials in clear text to the server. <\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Though you might plan to consider using SSL on the site or at least on the login page, but it might be impractical for the commercial web applications to use it. Considering Silverlight on any sensitive page will help to provide encryption of any data that is submitted data. It can be further enhanced with the following:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li><span style=\"font-size: 14pt;\"><strong>1- Password policy<\/strong>: Use a password policy that uses a strong password, expiration and also automatic locking of user accounts on few unsuccessful login attempts.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\"><strong>2- Password hashing<\/strong>: In case you are managing your own authentication store, don\u2019t forget to hash all user passwords.<\/span><\/li>\n<\/ul>\n<hr \/>\n<h6 style=\"text-align: justify;\"><span style=\"font-size: 18pt;\"><strong><span style=\"color: #003366;\">Data Validation and Page Authorization:<\/span> <\/strong><\/span><\/h6>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">Many small business applications are built as a series of isolated web pages. Designing each page to handle its own functionality and security may work good for any mini application, but this will not work when the concerns are for a larger web application.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\">The development of the web framework that is to be used by all ASP.Net web pages can help to maintain security in a consistent manner. The framework should be designed to employ data validation security checkpoints upon every user request.<\/span><\/p>\n<blockquote>\n<p style=\"box-shadow: 0 0 16px #cccccc; padding: 10px;\"><span style=\"font-size: 14pt;\"><span style=\"color: #800000;\"><strong>Also Read:<\/strong>\u00a0<a href=\"\/blog\/top-asp-net-blogging-platforms-to-power-your-website\"><span style=\"color: #ff0000;\">Top ASP.NET Blogging Platforms to Power Your Website<\/span><\/a><\/span><\/span><\/p>\n<\/blockquote>\n<p style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><br \/>\nThis will allow the application to streamline and also tighten various security aspects throughout the application. The framework should be developed as an isolated component and should be able to do the following functionality:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li><span style=\"font-size: 14pt;\"><strong>1-<\/strong> Authentication- check that the use is a valid user<\/span><\/li>\n<li><span style=\"font-size: 14pt;\"><strong>2-<\/strong> Authorization: ensure that the use has the right to do the current database operation<\/span><\/li>\n<li><span style=\"font-size: 14pt;\"><strong>3-<\/strong> Parameter validation: validation of all the parameters that are provided by the user for length, range, type and etc.<\/span><\/li>\n<li><span style=\"font-size: 14pt;\"><strong>4-<\/strong> User data: Send back data that the use is only entitled to view<\/span><\/li>\n<li><span style=\"font-size: 14pt;\"><strong>5-<\/strong> Database queries: try not to use dynamic SQL queries and only use parameters.<\/span><\/li>\n<\/ul>\n<blockquote>\n<hr \/>\n<p style=\"text-align: justify;\"><span style=\"color: #000080; font-size: 18pt;\">&#8220;Though security issues are often neglected, but its importance should never be underestimated.
