The first time you design a site for a client in a particular field, you’re learning a lot about the industry and the target market. What’s important to the business owner and the customer? The second web site you design in that field is a little easier. You’ve got some background information going in. As you do more site in that niche, things get better and easier.
I know a lot of small business owners who are extremely good at what they do: dentists who give unparalleled dental care, real estate agents who get you the best possible price for your house, and tax reviewers who save you thousands of dollars. Can you guess why they are so phenomenal in their field? It’s because they’ve spent their time developing those skills. They have not spent that time learning how to build a web site, configure a hosting package, and create email accounts.
Perhaps it’s unfair then that when we see a business card that has an email address from hotmail, yahoo, or any of a dozen other free email providers, we interpret that as an indication that this person and this business might be a fly-by-night operation. But that is in fact a judgment a lot of people make. A business that is using a free email address must be cheap. What other corners are they going to cut?
One of the most obvious vulnerabilities of web sites that interact with a database is the SQL injection attack. What’s that you ask? Suppose your site allows visitors to enter information that is used to generate a database query. A common example would be for the user to enter a password. A hacker will attempt to enter unexpected values that will cause unexpected SQL statements to be executed.
