Information Systems Security

You work for a medium-sized IT firm and your boss mentions that recently a number of employees have received calls from individuals who didn't identify themselves and asked a lot of questions about the company and its computer infrastructure. At first, he thought this was just a computer software vendor who was trying to sell your company some new product, but no vendor has approached the company. He also says several strange e-mails requesting personal information have been sent to employees. There have also been outsiders searching your company's trash dumpsters for recyclable containers. Your boss asks what you think about all of these strange incidents. Respond and be sure to provide recommendations on what should be done to secure your company's private and personal data - both electronically and in terms of what data may be going in the dumpster.  Include a detailed response on why employees should never answer any questions about their company's computer infrastructure to nonauthorized individuals.
