$4.$ Identify how systems administrators protect against internal and external security issues.

In a technical field steeped in protocols and algorithms, creativity is indeed a vital quality for system administrators. Enterprise troubleshooting often requires an open$-$minded, holistic, and creative approach to isolate critical issues in hardware, software, and the tech integrations that bind all of them together. Unique use cases arise every day and require system administrators to consider alternate avenues of approach and test out novel solutions to new problems. For this assignment, read the three scenarios. The resources included in each of the sections will help you construct a response that addresses the following:
