. How we can prevent Bypass authentication SQL attack

Posted by Alice Portman on December 7th, 2016

In this type of attack, attacker can log on to an application, with administrative powers, without feeds a valid username and password. Authentication bypass vulnerabilities can have so many different causes that it is not possible to give a wide-ranging list of methods to prevent.  But the following steps you can take include:

The penetration testing framework helps in to check for known vulnerabilities regarding authentication in IT infrastructure.

In authentication code development, it needs to be active monitoring in SQL injection vulnerabilities or buffer overflow errors.

Be aware of the sorts of vulnerabilities outlined in this article.

As ever, ensure that your applications are patched and up to date, and your network hardware is running the latest firmware.

URL method for prevention of SQL Injection-

URL method is filter approach. It is used to address the problem of SQL. It is a program that runs on the server before the servlet or JSP page.  A filter can be involved in one or more JSP pages or servlets. A filter examines the request and information going with these assets.

  • Authentication- user identity will results the Blocking or authentication.
  • Logging and auditing- it will tracks web application users.
  • Image conversion-it converts the images and Scale maps.
  • Data compression-Making downloads faster.
  • Localization- in this request is targeting and response to an individual.
  • XSL/T transformations of XML content- these targeting responses of web application more than one type of client system.

These are the applications filters.  There are many application filters, such as encryption, triggering resource access events, tokenizing, mime-type chaining, and caching. Single filter can be use for many webpages, it is the biggest advantages of using filter. It enhances the scalability and reusability.

 Designing of filter provide security against the SQL Injection. A  hacker attacks  with  the  help  of  URL alteration. This URL is not validated  thus this URL  request straight goes to the database server. The database server will act according that, so the little change in the URL by an hacker can take ruin all over  the  application.  By engaging  a filter  between  the  request and the  database  server  and  can  secure  the  web  application,  and  by  the  reusability feature of the servlets, there is need to be design a single filter for all pages.
