Network security is everyone's concern, and this applies to computer security as well. Many security breaches occur due to user ignorance of basic security principles, not malicious intent. Network and computer security are like an onion - there are multiple layers. Good security begins with understanding what you can do to keep your systems safe and implementing a layered approach. If you depend on one program or feature to secure your computer, then when (not if, but when) that dependency is breached, you may have personal information stolen or even have your computer taken over.
