For more than a decade, many network administrators have relied on SNMP, the Simple Network Management Protocol, to monitor and manage network devices. Now in its third release, SNMP has become the de facto standard for network management since its development in 1987. However, a recent report from the computer security watchdog CERT Coordination Center indicates that vulnerabilities in many SNMP implementations have left the products of more 100 vendors vulnerable to attack. Successful exploitation of these vulnerabilities could lead to unauthorized privileged access, denial of service attacks, or other undesirable behaviors.
