1 Assume that you are working as IT Security section in a company called Xybocin Corp. You company 6M has 150 employees in three departments which are ENG, BUSS and MAN. The company had no firewall to secure its network and the entire company is in one LAN and connected directly to Internet. However Xybocin Corp has one application proxy for SMTP and another Server that has all the customer financial data of Xybocin Corp. The Server is managed by MAN department. 

You have to create a proposal to submit in front of Xybocin Corp management for purchasing four hew firewalls with 18000 OMR. In the proposal you have to design/draw the new network architecture for the company for improving security with firewalls. Mention the advantages of each design components and its importance in improving security of the company. Also, if possible in your design give higher level of security to MAN department and highest level of security to the server with available firewalls. 

2 Mention why users are considered as weakest link in computer security with a relevant example, How you can solve this problem? 

3 Mention the importance of auditability in evaluating firewall products. Give an example.
