Securing Networks

Students learn how connecting devices creates new opportunities for adversaries and how defenders protect data in transit. They study common network attacks and the vulnerabilities behind them, then learn to apply managerial controls and configure wireless security. Students explore network segmentation and how it improves security, and they learn to place and configure firewalls using access control lists to manage traffic. They also analyze network log files to identify indicators of compromise.
