"Have you ever lost a term paper you worked on for weeks because your hard drive crashed or you deleted the wrong file? You were upset, angry, and frustrated. Multiply that paper and your feelings hundreds of times over, and you can understand why companies must protect computers, networks, and the information they store and transmit from a variety of potential threats. For example, security breaches of corporate information systems—from human hackers or electronic versions such as viruses and worms—are increasing at an alarming rate. The ever-increasing dependence on computers requires plans that cover human error, power outages, equipment failure, hacking, and terrorist attacks. To withstand natural disasters such as major fires, earthquakes, and floods, many companies install specialized fault-tolerant computer systems. Disasters are not the only threat to data. A great deal of data, much of it confidential, can easily be tapped or destroyed by anyone who knows about computers. Keeping your networks secure from unauthorized access—from internal as well as external sources—requires formal security policies and enforcement procedures. The increasing popularity of mobile devices—laptops, tablets, and cell phones—and wireless networks requires new types of security provisions. In response to mounting security concerns, companies have increased spending on technology to protect their IT infrastructure and data. Along with specialized hardware and software, companies need to develop specific security strategies that take a proactive approach to prevent security and technical problems before they start. However, a recent CIO article lamented the lack of basic security policies that companies only implement after a hack or data crisis."
