With the internet you can assume nothing when it comes to the safety of your web site and your information.  No matter how safe you think you may be with the things you are responsible for there is no safety net to protect you from the world at large.  Whether you think you are prepared or not the internet is part of your life and can be a great source of pleasure or woe.

Case in point:
I spent most of today trying to get a website back online that I knew wasn't safe but chose to do nothing about because it is relatively low on the hacker radar.  Turns out I was mistaken in this assumption and subsequently had to explain why the website went down, what data may have been compromised and spend most of the day adding code to circumvent the security issue I tried to ignore.  Nothing is sacred and nothing is safe; lesson learned.

Be careful with your information as you cannot always trust that websites are built to protect you from the onslaught of malicious code.
