As a network operator, there will be computer vulnerabilities on systems that you do not control. Nonetheless, you will be asked to protect the vulnerable systems. It is very important to keep yourself apprised of the latest vulnerabilities so that you can react quickly if one hits a system under your guard.

For this Discussion, perform your own independent research on current vulnerabilities. Then:

1. Describe one current exploit of network and host vulnerabilities. What are the risks that this exploit presents?

2. Describe two countermeasures for this exploit. Are there any sideeffects to these countermeasures? How effective are they?
