Surprise attacks by small, simply armed groups on modern, high-technology nations, sometimes referred to as asymetrical warfare, are on the rise and are effecting not only the security of individual companies but also the security of nations. The reason for the rise is that the entry costs of getting into cyber-crime are very low. The tools can be purchased on the internet for prices like $40 or $50. Groups have been formed to organize the perpetrators, especially in less developed nations offering high rewards, especially if major break-ins are achieved. The rewards can be impressive and the crime conducted with little personal risk or even inconvenience.
The cost is hitting companies big time. A recent UK report by PricewaterhouseCoopers showed that the cost of cybercrime has doubled in the last few years and continues to rise.
There is an urgent need for a concerted response to this crime wave, a response consisting of both private an public interests. A good rundown on this area is found by clicking this link.
