Acunetix Vulnerability Scanner for Website Safety

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.

A Penetration Test is often times conducted after the vulnerability scan. A penetration test attempts to exploit one or more of the vulnerabilities identified during the vulnerability scan. A penetration test attempts to verify if an identified vulnerability is actually susceptible to being exploited."A PCI Scan is a vulnerability scan that includes not only a report of the potential ways that hackers could use to gain access to the website, but it also outlines a solution for repairing or removing the vulnerability. If you run it, and there are no security issues, a penetration test is not necessary.

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.

The Payment Card Industry requires that scans be performed by an Approved Scanning Vendor (ASV). These vendors perform the vulnerability scans, penetration tests, and PCI scans. Many online security sites offer PCI scanning as a service to their customers. Often, these companies have an ASV partner who does the actual scanning and who sends the compliance reports. To increase the value of their service, many of these security sites offer seals - small images - that are displayed on the websites that they scan through their ASV partner.
