49020.17 Modem Usage

  • The critical and sensitive nature of the informational resources residing in CDCRCalifornia Department of Corrections and Rehabilitation’s computers requires stringent controls of devices attached to these computers, and over which persons are allowed to use these devices.

  • All access to the CDCRCalifornia Department of Corrections and Rehabilitation’s systems shall be monitored and controlled by EISEnterprise Information Services (formerly Information Services Division). All other means of accessing CDCRCalifornia Department of Corrections and Rehabilitation systems including, but not limited to, wireless communication devices and dialup modem, are prohibited unless approved by the ISOInformation Security Officer.

  • Modem use is restricted to computers not connected to the CDCRCalifornia Department of Corrections and Rehabilitation Network, unless such use is an approved part of the ISAInformation Systems Analyst. Requests for additional modems to be used within the CDCRCalifornia Department of Corrections and Rehabilitation teleprocessing environment are subject to approval.

  • Modems may be used to access remotely the CDCRCalifornia Department of Corrections and Rehabilitation network resources through EISEnterprise Information Services (formerly Information Services Division)-supported access mechanisms. They may also be used to provide access to the Internet and specific destinations and e-mail capability when such access is not available through the CDCRCalifornia Department of Corrections and Rehabilitation network resources. Justification and procurement of modems for these purposes shall be conducted in accordance with DOMDepartment Operations Manual, Chapter 4, Article 41, Departmental Workgroup Computing Policy.

  • Specific restrictions on the use of modems are:

    • There shall be no inmate or parolee access to any computer for which a modem has been approved. Computers that are attached to modems shall not be located in areas where inmates or parolees have access.

    • No applications that were developed by inmates shall be implemented on a modem-equipped computer.

    • No modems shall be installed on any computer that is a part of a LANLocal Area Network that has been approved for inmate use.

    • The location and usage of all modems must be tracked and monitored at all times.

    • Computers with “pocket” modems may not be used within the secured perimeter of facilities. They shall not be used in parole offices unless the area where the modem is to be used is secured from parolee access.

    • Non-CDCRCalifornia Department of Corrections and Rehabilitation computers shall not access the CDCRCalifornia Department of Corrections and Rehabilitation Network via modem.
