The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

SQLi Testing

Asked by pma111 in Miscellaneous Security

Im trying to get my head around SQL Injection attacks and where to start to identify SQLi vulnerabilities in our own applications. I am not from a web development background, albeit am learning on a daily basis, so could do with some basic pointers to set me on the right track. Basically we have some test applications on a test server which we want to see if there are any SQL injection flaws in them. All our applications were coded in asp.net / c#. Some of the underlying databases are MS Access, whilst others are SQL Server.

My questions are:

1.By viewing a pages source code (view > source in IE), will I be able to get a clue about which stored procedure is being run when a user submits data, or searches for something in the application. Have you any tips on how to find the name of SPs being fired off.
2.Would you say MS Access is more susceptible to SQLi than SQL Server etc. I wasnt aware MS Access could run stored procedures.
3.Which elements need to be reviewed for SQLI flaws, both the web development pages and the SQL query, stored procedure? Anything else?
4.Do you do manual SQLi testing or use any specific freeware tools?
