Activity: Turn on remote access controls during business hours. This will limit remote ssh access to CDS to users who have approved work permits and have been granted access by the operator. The purpose of this to test the remote access control system, by allowing operators to administer the system and to condition the remote users to acquiring a work permit and coordinating with the operator prior to remotely accessing CDS. At this time it is proposed that this system only be enabled 8am - 4pm Monday-Friday while there is typically operator coverage. During O2 this could be enabled 24x7. As users will be locked out of CDS until coordinating with the operator, it is expected that there will be increased support requests until users and operators get used to the workflow.
