    Attack Prevention 3 Attack Prevention: Preventing Cyber Attacks Technology is everywhere , which is evident in the everyday products that we as a society use such as computers, cell phones, global positioning devices, and the Internet. As technology expands and grows, so does the reliance and dependence on these types of products. But reliance and dependence are not the only things that technology brings. Cyber attacks are a gradually increasing occurrence that is derived from technology; however, s topping these types of attacks before they occur is usually more difficult than can be expected, but is overall not impossible.
