GM Scan Tools Good, Better and Best

GM’s hardware (Tech 2, MDI, MDI2, VXdiag vcx nano gm, etc.) and software (Tech2win, GlobalTis, TIS2000, GDS2, etc) are designed and validated to work within specified hardware and software versions. This document details the ideal computer scenarios with which GM hardware and software will function as designed. Non-compliance could result in undesired results for which GM is not responsible and will not support.

General Notes
The GM IT guidelines are organized as follows:
  • Good – the minimum acceptable systems capability/components for conducting diagnostics and programming with related GM hardware and
  • Better – the systems infrastructure capability/components that will deliver better performance and security while seeking to maximize the lifecycle of the
  • Best – the systems infrastructure capability/components that will deliver best performance and security while seeking to maximize the lifecycle of the
NOTE: If you are looking to purchase new infrastructure, systems or solutions, please
adhere to the specifications outlined in the “Better or Best” sections.
Hardware
The following section details guidelines for required hardware and software as well as a guide for purchasing new hardware and software. NOTE: GM hardware and software must be utilized on a dedicated computer.
Consumer-Grade versus Enterprise-Grade: Most computer manufacturers offer two different grades of computers: consumer-grade hardware intended for home and personal use, and enterprise-grade hardware intended for businesses. While the price of consumer-grade hardware may seem attractive for independent businesses, oftentimes the total cost of ownership ends up being greater due to the limited functionality, higher failure rates, and more complex support.

Desktop Security
 GoodBetterBest
PC Virus MonitoringEnterprise-grade, antivirus products should be installed on all PCs and configured to automatically perform the following:

·         Download and install most current virus signature updates
·         Actively monitor for viruses
·         Quarantine and eradicate infected files
·         Antivirus solution should include antivirus, anti-spyware, intrusion prevention, application control, spam control and rootkit detection
Patch Management·         GM recommends that patch management be performed on every PC to ensure each workstation has current patches.

·         Workstation Management should include remote monitoring of hardware/software failures, down servers, low disk space, excessive CPU usage and excessive memory usage. Install critical security patches within one month of
release.
Password ProtectionEmployees have multiple user ID’s and passwords used to access the tools that support user’s job roles. Implementing a password management policy is a significant piece of data security and access control.

All passwords should be promptly changed if suspected of/are being comprised, or disclosed to vendors for maintenance/support.
•  Refrain from divulging passwords unless absolutely necessary (i.e., helpdesk
assistance)
•  Protect stored passwords – discourage employees from writing down access information and keeping it in plain sight of passerby (i.e., username & password written on post it note nearby workspace).
•  Passwords should be encrypted when transmitted electronically.
•  Passwords must be changed every 90 days.
•  Users are not able to reuse their last five (5) passwords.
•  User accounts are locked-out or suspended after the tenth (10) failed login attempts.
•  Remove all employee credentials from all network devices immediately upon employment ending.
