If you use computers in your business to function, then you might not want the computer to be down when you

will need to place orders with the suppliers whenever a customer tries to transact. You will need to make sure

that the computer is secure and always working otherwise the business will find it very hard to recover. Security

means having policies and procedures in place which will be used as a measure to prevent unauthorised access,

alternation, theft or any physical damage to the information system. Controls are methods and policies in place

which will ensure the organisation and assets are safe. The controls will also ensure the records are reliable and

operational and up to management standards.
