During an investigation of a cloud-based webmail login using compromised credentials, a security analyst needs to review information about the source IP for the login. Which of the following logs should the analyst retrieve?

Network logs are essential for tracking and analyzing all incoming and outgoing traffic on a network. They contain records of source and destination IP addresses, which are vital for understanding the context of a login attempt, especially when compromised credentials are involved. This makes them the most relevant logs for the analyst's investigation.

System logs provide information about the operating system's events, including system errors and status messages. Although they can offer some insights into system health and performance, they do not specifically track network activity or provide source IP information relevant to login attempts.

Firewall logs record traffic that is allowed or denied by the firewall rules in place. While they might indicate actions taken on specific traffic, they do not provide comprehensive details about all login attempts, particularly in relation to the source IP of compromised credentials.
