The command snmpwalk -v 2c -c public 192.168.1.23 is used to query SNMP (Simple Network Management Protocol) data from a device. Here's the purpose in the context provided:
* SNMP Enumeration:
* Function: snmpwalk is used to retrieve a large amount of information from the target device using SNMP.
* Version: -v 2c specifies the SNMP version.
* Community String: -c public specifies the community string, which is essentially a password for SNMP queries.
* Purpose of the Command:
* Validate Results: The tester uses SNMP to gather detailed information about the network devices to confirm the findings of the vulnerability scanner and remove any false positives.
* Detailed Information: SNMP can provide detailed information about device configurations, network interfaces, and other settings that can validate the scanner's results.
* Comparison with Other Options:
* Bypassing Defensive Systems (A): Not directly related to SNMP enumeration.
* Using Automation Tools (B): While SNMPwalk is automated, the primary purpose here is validation.
* Script Exploits (C): SNMPwalk is not used for scripting exploits but for information gathering.
By using snmpwalk, the tester is validating the results from the vulnerability scanner and removing any false positives, ensuring accurate reporting.
