Research the costs associated with the following items when implemented by a firm with 1,000 employees and 100 servers (since you would research only one resource for each of these in real life, you will need to obtain three (3) costs for each item):

1. Managed antivirus software (not open source) licenses for 500 workstations

2. Cisco firewall (other than residential models from LinkSys)

3. Tripwire host-based IDS for 10 servers

4. Java programming continuing education training program for 10 employees

5. Checkpoint firewall solutions

Once the costs have been identified, compare and contrast the costs for each item. Justify your choice for each item (cost, service, vendor experience, etc.). Additionally, identify if any of these require contingency plans due to known and unknown risks, and factor that cost in as well.
