UDP Table

Overview

Evidence: Udp Table Description: Collect Udp Table Category: Network Platform: Linux Short Name: udptable Is Parsed: Yes Sent to Investigation Hub: Yes Collect File(s): No

Background

Linux UDP table provides information about active UDP connections and network sockets. This data is essential for understanding network connectivity and detecting unauthorized network connections.

Data Collected

This collector gathers structured data about udp table.

Udp Table Data

Field	Description	Example
ID	Primary key (auto-increment)	1
Inode	Socket inode number	12345
ProcessId	Process ID using the socket	1234
UserId	User ID of the process	1000
LocalIP	Local IP address	0.0.0.0
LocalPort	Local port number	53
RemoteIP	Remote IP address	0.0.0.0
RemotePort	Remote port number	0
State	Connection state	UNCONN

Collection Method

This collector parses the necessary data from the udp_table table.

This collector collects files from the following locations:

• /proc/net/udp

• /proc/net/udp6

Usage

This evidence is crucial for forensic investigations as it provides UDP connection information. It helps investigators understand network connectivity, detect unauthorized connections, and investigate network-based attacks. The data can reveal active connections, network sockets, and potential network vulnerabilities. Analysts can use this information to identify network compromises, trace network activities, and assess network security posture.

Notes

This data may contain sensitive information that should be handled according to data protection requirements. Ensure proper chain of custody is maintained during collection and analysis.
