Hide detailed error messages from end users, but store the information where administrators can access it. Use the event log to store error messages so that systems administrators can easily analyze your application s output. When you must display detailed error messages to end users, provide detailed information only to those users who are authenticated and highly privileged, or who are connecting from the local computer. Reduce the application s vulnerability to denial-of-service attacks by closing open database connections when a failure occurs. Reduce privileges when a failure occurs to reduce the opportunity for an attacker to exploit a weakness in your error-handling code.

You have been hired by Trey Research to perform a code security review of an internal Windows Forms application used by the Human Resources team to control payroll. The application is used by both permanent employees and contractors, and the IT department is concerned that a contractor will gain access to employees personal information or, even worse, modify the data. Your boss asks you to interview a few of the organization s personnel and then make recommendations to reduce the application s vulnerabilities.
Interviews
Following is a list of company personnel interviewed and their statements:
IT Manager I trust our employees not to mess around with the payroll data base, but some of our contractors seem a little shady. Just make sure they can t see what I er, the employees earn. Systems Administrator As far as I know, nobody has ever abused our payroll application. The problem is, I have no way of knowing. For all I know, that temp with the mustache is changing my salary right now. I really need to be able to monitor that application. If I could use our existing event management system to detect problems, that would be awesome. Chief Security Officer I am more concerned about internal employees abus ing this application than I am about the contractors. Internal employees are more likely to be motivated to examine others salaries. Certainly, the motivation for changing their salaries is there.
Exercise
Answer the following questions for your boss: 1. What types of exploits is the application potentially vulnerable to 2. How can an attacker exploit a Windows Forms application 3. During your code review, what problems would you look for 4. What recommendation can you make to address the systems administrator s concern

Summary
Follow a three-step process to validate user input: constrain, reject, and sanitize. Prevent canonicalization problems by using the .NET Framework to manually canonicalize paths before processing them. Reduce the likelihood of being exploited by a SQL injection attack by rigorously validating user input that will be included in a database query, using parameterized SQL commands instead of dynamic SQL queries, and using stored procedures. Remove HTML encoding from user input to reduce your application s vulnerabili ties to CSS. Detailed error messages are a potentially useful source of information to an attacker. Therefore, you should display detailed error messages only to users who have been authenticated. To prevent failures from causing additional problems, close all open connections, and fail to a more secure mode.
