What are the differences between network forensics and host-based forensics?

Network-based incidents and incidents focused on individual devices present distinct differences in terms of scope, methodology, and impact.

1. Scope:

– Network-based incidents involve analyzing activities, traffic, and anomalies across an entire network infrastructure.

– Incidents on individual devices involve examining specific devices, their logs, configurations, and any potential threats or compromises.

2. Methodology:

– Network-based incidents require monitoring network traffic, logs, and patterns to identify potential threats or intrusions.

– Incidents on individual devices demand examining system logs, antivirus reports, installed software, and user behaviors to determine the source of an issue.

3. Impact:

– Network-based incidents can impact multiple devices, systems, or services connected to the network.

– Incidents on individual devices may have more localized effects but can also serve as entry points for broader network attacks if compromised.

In summary, investigating network-based incidents involves a more holistic approach, considering the interconnected nature of devices and services, while incidents on individual devices typically focus on specific endpoints to identify and resolve security issues.
