Security – Risk Management

PG&E utilizes the following five information classifications:

  • PG&E Public

Anything produced for public review and available to anyone inside or outside the

  • company. This includes materials such as press releases, advertisements, or bill inserts.
  • PG&E Internal

Information intended primarily for use within PG&E, such as organization charts,

personnel numbers, and company email messages. Distribution should be limited based

  • n business need to know, and access controls are required.
  • PG&E Confidential

Information such as trade secrets, customer or employee information, and passwords that should be shared solely on a business need to know basis. PG&E Confidential data must be encrypted for storage and transmission if electronic and, if printed, protected through controlled physical access, such as a locked filing cabinet.

  • PG&E Restricted or PG&E Privileged (Law only)

Information such as Social Security Numbers, undisclosed financial information, and protected health information should be shared solely on a business need to know basis. Data must be for storage and transmission encrypted if electronic and, if printed, protected through controlled physical access. Note that PG&E Privileged is only used by Law.

Security is Physical

Control of assets is critical to our business:

  • San Jose Mercury News

June 4th, 2013

In the early-morning hours of April 16, someone opened fire at the utility's substation on Metcalf Road near Highway 101. The gunshots damaged five transformers and caused cooling oil to leak from a transformer bank, and the damage prompted state regulators to urge electricity conservation in the ensuing days. AT&T phone service in the area was also affected.

Critical Infrastructure Protection (CIP) standards

Version 5 now requires the following:

  • Encryption
  • Role-based instead of risk-based classifications
  • Multiple levels of compliance – Low, Medium and High Impact (in theory, a company could

have 10 facilities of which six are low impact facilities, three are medium impact facilities, and

  • ne is a high impact facility)
  • New terminology (such as BES Cyber Asset)
  • All serial connections are to be considered
  • Multi-factor authentication requirements
  • Triggers are required to be defined for recovery plans
  • All software (COTS and custom) must be known
  • All security patches from the beginning of time on each device must be known
