How to Secure Web Applications Built on ASP.Net?

ASP.Net is an open source, server side web application framework which runs on Windows. It allows a developer to choose many different working environments. This framework is largely preferred by enterprises for developing web applications.  However, older versions of Dot Net may have security flaws which provide an open invitation to hackers and other malicious web elements. These issues need to be identified and fixed as soon as possible; especially on web applications that transmit a wide range of information; examples being banking websites; staffing management portals, and commuting web applications similar to the ones that are operated by transport departments and/or  travel operators.

The usage of Asp.Net to develop web applications is definitely recommended; but as every other framework; older versions of Dot Net also have certain loopholes. However, certain procedures can be followed to ensure that enterprise as well as business web applications remain secure and ward off any attempts by hackers and/or others to disrupt a web application’s safe activity. These include:

Strong Authentication:  The first step will be to create strong passwords for web administrators who do not have any identifiable pattern or sequence of numbers/letters/characters.  Multi-factor authentication can also be used in which administrators, contributors and employees with access to a website’s backend must enter valid user ID, password as well as a unique authenticator number. For all these, it should be ensured that the content management system, scripts and plugins of a web application is continuously updated.

Usage of Content Security Policies: Cross-site Scripting (XSS) attacks can affect an application built on Dot Net. These attacks occur when a hacker troublesome JavaScript code is inserted into a website pages without authorization.  This can in fact cause the impact of spam on a website’s visitors who are exposed to the code. The best solution for this would be the utilization of a Content Security Policy (CSP) is that can keep a website secure from XSS attacks. Using CSP requires will require adding accurate HTTP headers to a webpage. These headers provide a string of directives that tell browsers which domains are okay and what exceptions to consider.  However, usage of content security policies will need assistance from experienced cyber security analysts in Florida.

Site-Wide SSL Connection: A Secure Sockets Layer (SSL) certificate ensures a secure connection between a website and its users or visitors.  It does this by securely encrypting all information that passes between browsers and servers. With an SSL connection, hackers can be prevented from intercepting as well as accessing data in transit between users’ browsers and web servers.

Setting-up Backups: Website backups are critical to the protection of your data from hackers, administrator errors and loss.  Such measures can be very useful in unpredicted circumstances such as server issues or even during website maintenance. These can be automated or handled by a web-hosting provider in the United States.
