Security Event Triage: Leveraging Existing Security Device Alerts

Identifying suspicious activity on your network can be achieved by analyzing security device logs. In this course, Security Event Triage: Leveraging Existing Security Device Alerts, you'll learn how to analyze security device logs looking for security problems. First, you'll learn about network security devices and the relationship between the OSI model and the ability to decipher the meaning of network traffic captures. Next, you'll see how to analyze firewall logs to identify abnormal activity which could indicate a security compromise, and how analyzing network access control (NAC) logs can identify questionable host and network connectivity for unauthenticated as well as authenticated devices. Finally, you'll explore how to use cloud-based methods such as cloud packet capturing and centralized security monitoring to identify potential security problems in the cloud. When you're done with this course, you'll have the foundational knowledge of continuous monitoring and interpretation of correlated log events needed to gain the best possible picture of network security events.
