Boreal, the SNMP Vulnerabilities Test Suite, is now incorporated into SilverCreek, the SNMP Test Suite. SilverCreek is composed of many test suites and more information on the SNMP Vulnerability Test Suite can be found here.
The objective of the SilverCreek SNMP Vulnerability Test Suite is to identify vulnerabilities in the ASN.1 encapsulation of the SNMP packets in a device so that they may be corrected and Denial of Service attacks prevented.
