312-38 Exam Dumps : Certified Network Defender (CND)

A Network Protocol Analyzer, such as Wireshark, is a tool that captures and analyzes packets in real-time, displaying them in a human-readable format. It allows network administrators to inspect individual packets deeply, which is essential for identifying and investigating data leaks within an organization. By examining the packet contents, the source and destination of the traffic, and other details, a Network Protocol Analyzer can help pinpoint the exact nature and origin of a data leak.

References: The use of Network Protocol Analyzers for investigating data leaks is a standard practice in network security, aligning with the objectives of the EC-Council’s Certified Network Defender (CND) program. The capabilities of these tools are detailed in resources like the Wireshark user guide and network security best practices123.

AWS CloudTrail is the service that enables governance, compliance, operational auditing, and risk auditing of your AWS account. It allows you to log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. CloudTrail provides event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services. This event history simplifies security analysis, resource change tracking, and troubleshooting. It is specifically designed for reviewing account activity and events for supported services made by AWS.

References: The information about AWS CloudTrail as a service for viewing account activity and events is detailed in the AWS CloudTrail user guide and is a fundamental aspect of AWS security best practices1.

Daniel is adopting a Reactive network security approach. This approach involves monitoring network traffic to detect any abnormalities or intrusions as they occur. The goal of reactive security is to identify and respond to threats in real-time. It is a part of the broader defense strategy that includes Protect, Detect, Respond, and Predict, where ‘Detect’ aligns with the reactive approach. By using network monitoring tools, Daniel is able to observe the network for any signs of compromise or unusual activity and then take appropriate action to mitigate the threat.

References: The Certified Network Defender (CND) program by EC-Council emphasizes the importance of a continual/adaptive security strategy, which includes the ability to detect ongoing threats as a critical component of network defense12. This strategy is further detailed in the CND course outline, which covers key topics such as network traffic monitoring and analysis, indicating the reactive nature of such activities1.
