The Company Where You Work Was Recently the Victim of a Logic

The company where you work was recently the victim of a logic bomb. The company has a policy against connecting flash drives, writable CDs/DVDs, etc. and had even had the ports and drives for those devices removed from employees computers. The CFO does not understand how the malware appeared within the company given these preventative measures and wonders what other threats may already be on the network. Prepare a report on the various types of malware, how they may gain access to the corporate network, and how the company can protect against this type of attack.
