Prevent SQL Injection with Acunetix Vulnerability Scanner

by Kate Bailey

One of the most effective methods of preventing SQL injection from being used is to thoroughly validate every input from the user, by identifying all possible meta-characters which could be utilized by the database system and filtering them out. Filters should be in place to remove everything but known good data. An account lockout policy should also be in place to prevent the brute force guessing of passwords. Acunetix Vulnerability Scanners can help.

All validation for security purposes must be carried out within the server side script and not thorough client side authentication - such as JavaScript - as it can easily be bypassed by the user disabling JavaScript in their browser. When dealing with a numeric input, such as age, telephone number or credit/debit card number the value of the variable should be processed through a specially constructed function to ensure that the data only comprises of numeric characters (and possibly spaces). Similar functions can be constructed to handle other data types such as Dates, Integers and Floats. Alternatively, for some numeric fields such as integers or dates the input method could be through the use of a drop-down selection box. If the input is selected from a dropdown box it would be generated by the source code and no validation will be necessary.

In December 2006, University of Colorado, Boulder experienced a hack attack that resulted in the theft of thousands of names and social security numbers - a total of 17,500 records were compromised. University of Texas, Dallas, reported in December 2006 that the data of 35,000 individuals (current students and alumni) was compromised. Social security numbers were exposed, according to the Privacy Clearing House.

For PCI scanning to be compliant, at a minimum it must be run against the internal and external networks on a quarterly basis. It also must be run after any significant changes in the network like installations, changes in network topology, firewall rule modifications, product upgrades, etc. It is important to have some kind of vulnerability scanner if you have a business online.

Recent trends over the past 12 months show that there is a shift from such disruptive vandalism that gains notoriety towards theft of data that translates into profit. The report on 2006 is still to be published. If you are looking for website security for your home business or online business, a vulnerability scanner is what you need. Acunetix Vulnerability Scanner will help keep your website safe.
