SNMP – a goldmine of information just waiting to be discovered


Simple Network Management Protocol (SNMP) is commonly mismanaged by busy administrators and developers. Frequently, you will see default community strings or community strings that are reused throughout the entire organization you are testing. You will want to ensure that your clients are using the most secure version of SNMP and that you cannot simply walk in to a building, unplug a phone, and sniff the community string. Newer versions of SNMP include strong encryption to avoid such flaws.
