Hacking a network of computers in a company for example can disrupt work and incur major costs in the repair of the network overall including the installation of a higher range of security methods. The time wasted and costs associated with this can be harmful to a company especially if private or financial files have been accessed. The repercussions can be extreme in such cases. Many companies now hire people with hacking skills in order to asses how vulnerable their networking systems are and also to figure out what security methods will give them the best results. The more prolific the company, the more security is necessary in order to protect their systems.
