In reaction to the continually changing business climate companies develop many business strategies to increase their competitiveness and improve profitability. Companies regularly reshape themselves continually exploring new markets and developing new products. When they can't expand into new markets or develop new products on their own, they seek alternatives. These alternatives include merging with or acquiring other companies to create a single more capable company. Companies acquire other companies for a wide variety of reasons. In some cases company survival may actually be the reason. What does this condition mean to the security professional?
