Which Of The Following Is A Cisco Ios Feature That Can Collect Time

Identify the key Cisco IOS feature that can collect timestamps of traffic sent between specific source and destination addresses for audit review purposes.

Paper For Above instruction

In the realm of network security and management, the ability to accurately track and analyze traffic flows is crucial. Cisco IOS, the operating system used on Cisco routers and switches, offers several features that facilitate network monitoring, management, and security auditing. Among these features, NetFlow stands out as a primary capability for collecting detailed traffic data, including timestamps of data packets exchanged between sources and destinations.

NetFlow is a network protocol developed by Cisco that collects IP traffic information and provides comprehensive visibility into traffic flow. This feature allows network administrators to gather statistics about the IP traffic traversing Cisco devices, including source and destination IP addresses, port numbers, Layer 4 protocol types, interface information, and timestamps. The collected data can be used for network planning, capacity management, troubleshooting, and security auditing (Cisco, 2020).

Specifically, NetFlow provides the ability to record timestamps of when traffic flows occur, which is essential during audit processes. When a network administrator needs to review traffic sent between a particular source and destination, NetFlow logs detailed flow records that include start and end times of flows, duration, volume, and other critical parameters (Li and Herrod, 2021). This granularity ensures that network activities can be reconstructed and analyzed precisely, making NetFlow an indispensable tool for security audits and compliance checks.

CS-MARS, another Cisco product, integrates with network devices to provide intrusion analysis and events correlation, but it does not directly collect timestamp data at the flow level from IOS devices. SNMPv3, meanwhile, is primarily used for network management and device monitoring, lacking detailed flow-based timestamp capabilities required for traffic audits (Cisco, 2019). RMON (Remote Network Monitoring) offers traffic monitoring, but it is primarily focused on statistics and alarms rather than detailed flow timestamps. Therefore, the best answer for the feature capable of collecting timestamps for traffic flow review in Cisco IOS is NetFlow.

In conclusion, Cisco IOS's NetFlow feature provides the necessary detailed traffic flow data, including timestamps, typically used in audit scenarios for analyzing traffic between specific source and destination hosts. This makes NetFlow an essential component of network visibility and security audit tools within Cisco network environments.
