Traffic mirroring is a technique that copies the traffic from a source port or VLAN to a destination port or VLAN, where it can be analyzed by a security device or tool. Traffic mirroring does not affect the original traffic flow and does not introduce any latency or modification to the packets. Inline traffic interrogation is a technique that forwards the traffic directly to the security device or tool, where it can be inspected and modified before being sent to the destination. Inline traffic interrogation can introduce latency and affect the performance of the network. References:

During the collection phase of the forensic process, data related to a specific event is labeled and recorded to preserve its integrity. This step ensures that the data remains unaltered and authentic from the time of collection until it is presented as evidence, maintaining the chain of custody.

Full packet capture data involves storing the entire content of packets that traverse a network. This type of data is comprehensive and allows for detailed analysis but requires a significant amount of storage space compared to other data types like transaction, statistical, or session data.
