The use of ICT in companies and organizations is on the rise today. Each company relies on more than one ICT systems for their operations. The reason behind this is that ICT improves the ease through which individuals access company services and information. It has also made it easy for companies to deliver services to their customers. For instance, an individual can know the services offered by a company and even contact them from the company's website. Companies use computer networks as a way of transferring data from one department to another. Computer networks are also used for communication between the company and outsiders. Companies rely on database management systems for storage of data about their customers and staff.Despite the advantages brought about by the use of ICT systems, they present a threat to the company if they are not well secured. Hackers can take advantage of the security loopholes associated with such systems to gain illegal access into the sensitive data belonging to the company. If this happens, the company will incur huge loses, including being sued, losing customers and even being closed.
