First off, please understand that all sites and hosted venues are susceptible to site security issues. This includes do it yourself builders as well. And, this is not something to take lightly especially where your customers are concerned.
It’s one thing to protect your website files but are you making sure your customer data is protected? We have all read about the large department stores getting hacked and then losing their customer credit card information to the hackers. Something like this could ruin even the smallest of businesses with lawsuits, etc.. Bottom line, it’s your job to reduce the likelihood of getting hacked especially if you are collecting user data of any kind. So how do you protect your site?
