What is the first step in network forensics after detecting an incident?
The first step in network forensics is to preserve the network evidence to avoid contamination and loss of data.
What is the main objective of malware analysis?
Malware analysis aims to understand the nature and behavior of malware in order to determine how it spreads and how to mitigate its impact.
How can you identify suspicious network traffic during an incident?
Suspicious network traffic is typically identified by unusual patterns, such as high traffic volume, odd source and destination IP addresses, or traffic to unexpected ports.
Why is timestamp analysis important in network forensics?
Timestamp analysis helps to construct the timeline of the incident, identifying when specific activities occurred.
What is the purpose of extracting artifacts from a compromised system?
Artifacts provide critical evidence of the attacker's activities and help in understanding how the system was compromised.
How can you detect malware using network traffic analysis?
