SC-15: COLLABORATIVE COMPUTING DEVICES

TAILORED FOR INDUSTRIAL CONTROL SYSTEMS

  • ICS Control Baselines:
  • Low
  • Moderate
  • High

The information system:

    • a. Prohibits remote activation of collaborative computing devices with the following exceptions: [Assignment: organization-defined exceptions where remote activation is to be allowed]; and
    • b. Provides an explicit indication of use to users physically present at the devices.

SUPPLEMENTAL GUIDANCE

Collaborative computing devices include, for example, networked white boards, cameras, and microphones. Explicit indication of use includes, for example, signals to users when collaborative computing devices are activated.

ICS SUPPLEMENTAL GUIDANCE

No ICS Supplemental Guidance.

CONTROL ENHANCEMENTS

SC-15 (1) COLLABORATIVE COMPUTING DEVICES | PHYSICAL DISCONNECT

NOT SELECTED FOR THE NIST ISC CONTROL SET

The information system provides physical disconnect of collaborative computing devices in a manner that supports ease of use.

Supplemental Guidance:

Failing to physically disconnect from collaborative computing devices can result in subsequent compromises of organizational information. Providing easy methods to physically disconnect from such devices after a collaborative computing session helps to ensure that participants actually carry out the disconnect activity without having to go through complex and tedious procedures.

SC-15 (2) COLLABORATIVE COMPUTING DEVICES | BLOCKING INBOUND / OUTBOUND COMMUNICATIONS TRAFFIC

NOT SELECTED FOR THE NIST ISC CONTROL SET

[Withdrawn: Incorporated into SC-7].

SC-15 (3) COLLABORATIVE COMPUTING DEVICES | DISABLING / REMOVAL IN SECURE WORK AREAS

NOT SELECTED FOR THE NIST ISC CONTROL SET

The organization disables or removes collaborative computing devices from [Assignment: organization-defined information systems or information system components] in [Assignment: organization-defined secure work areas].

Supplemental Guidance:

Failing to disable or remove collaborative computing devices from information systems or information system components can result in subsequent compromises of organizational information including, for example, eavesdropping on conversations.

SC-15 (4) COLLABORATIVE COMPUTING DEVICES | EXPLICITLY INDICATE CURRENT PARTICIPANTS

NOT SELECTED FOR THE NIST ISC CONTROL SET

The information system provides an explicit indication of current participants in [Assignment: organization-defined online meetings and teleconferences].

Supplemental Guidance:

This control enhancement helps to prevent unauthorized individuals from participating in collaborative computing sessions without the explicit knowledge of other participants.
