Cabletron Systems –
Enterasys Division. – Consultant
In VPN SQA (2004)
Hired by Cabletron System’s – Enterasys Division to conduct the quality Assurance for their VPN Vectra System. I was solely responsible for the Quality Assurance of the Remote Access Configuration and the VPN Monitoring Tools developed to support the Vectra VPN Solution. I defined the representative test environment to conduct the tests, built a test lab for the testing and conducted the testing after writing a test strategy and test plan and test procedures for the project. The Remote Access Configuration Tool is responsible for generating multiple “Remote User Configurations” from a basic Security Policy Database (SPD) file template. Information from the Remote User Configuration – Security Policy Database is sent the appropriate RADIUS database(s). The Security Policy Database files may or may not be encrypted. The configuration tool was provided as a way for Users to only have to put connection information in one place and have that information propageted to other services. Each connection in the newly created SPD file maintained the same pre-shared Key. It was my responsibility to create tests that verified that the appropriate RADIUS databases were updated with the new user information. The configuration tool was tightly coupled with another software product - the IRE Client which is the software that was used to create one or more template SPD files. All the Radius fields that were populated i.e. FQDN, Authentication method, Tunnel related passwords, pre-shared keys, Tunnel type, Filter ID, ESP etc were verified for correct data content and integrity. The verified parameters were then used in different VPN configurations to ensure the proper operation and use of inter- related VPN configuration and operation parameters.
I was also charged with the responsibility of testing the Cabletron’s VPN Monitoring Tool . The VPN Monitoring Tool is a Java-based management tool used to monitor the performance and throughput of tunnels on Cabletron routers within a Cabletron VPN environment. The Tool allows the user to view the current operating statistics for a VPN device with automatic updates of information. The monitored data is gathered from several Management Information Bases (MIBS) supported by the VPN devices. These MIBs include the Interface Group MIB (RFC 1213), IP Tunnel MIB (RFC 2667), the IPSec Monitoring MIB(s), the Layer Two Tunneling Protocol (L2TP) MIB and the Cabletron’s VPN Monitoring MIB. The Monitored Data is organized into distinct categories, including : Tunnel S ummary, Tunnel Counters, Tunnel Details, L2TP Tunnel Summary, L2TP Tunnel Summary Counters, L2TP Tunnel Details, L2TP Session Summary and L2TP Session Counters. The Tool displays a single view per browser window and each individual view performed its own polling for SNMP data during a configurable polling interval . The Monitored and Historical data were displayed for specific devices, designated by their IP Address. Wrote and conducted tests to asertain the scalability of the VPN Monitoring Tool. I am in the process of developing automated tests for both the VPN Remote Configuration and the VPN Monitoring Tools.
GTE Internetworking - Consultant in SQA Sept 2003 – June 2004
Provided technical
leadership to a team of 5 SQA Consultants charged with the responsibility for
testing the GTE Internetworking's managed Virtual Private Network (VPN)
Advantage service. The development effort was projected for five years but the
initial commercial release happened in December 1998. The VPN Advantage service
provides intranets , extranets and secure access cost
effectively by using the public internet as a communication medium for private
networks. The key challenges were Security and Quality of Service of the public
internet infrastructure and the performance and management of the VPN Service.
As the technical lead of the software quality assurance team, I wrote and
implemented the VPN testing strategy which included the testing of the VPN
Advantage implement- ation of IPsec
for secure communications. The security requirements for the service involved
shared secret as well as digital certificates using different Certificate Authorities
and Security Associations. The security services include Access Control,
connectionless integrity, data orrigin
authentication, anti replay and traffic flow confidentiality. VPN Advantage is
designed to use Commercial of the Shelf (COTS) gateways, Firewalls and hardware
encryption devices to implement secure networks. I successfully used several
automation tools for test execution - these include NextPoint
System's S3, Ganymede Software's Chariot and Seque's
Silk to implement a semi automated testing environment. Defined the high level
require- ments for a Test Management System designed
to move the test effort close to a fully automated environment. I Conducted
hand on testing for the Configurator and the Network
Management Subsystems of the VPN Advantage service. I Provided
technical guidance to the SQA team and briefed top level management during the
course of the test effort. I was instrumental in defining the SQA process for
the project.
