Phoenix fabs, power plants and hospitals all hand out contractor access. Few can say who still has it.

Usually, yes. The vendor engineer requests a session to a named tool for a set window, a fab sponsor approves it, the session runs through a recorded gateway into the tool network, and access closes when the window ends. Most equipment makers can support this once their service contract spells it out.

Under A.R.S. §18-552 it runs from the point you determine a breach occurred, not from the first alert. If law enforcement says notice would impede a criminal investigation, the 45 days start once they say it no longer will. Let counsel own the determination date, since it fixes your deadline.

For the access control requirements in CIP-004 and CIP-005, yes. That means authorization records, periodic access verification, revocation tracking and remote access through intermediate systems. We don't act as your auditor, and substation network design and physical security stay with your own teams.

Keep plant identities apart from corporate ones where your customer's security terms require it. Give contractors sponsored accounts with end dates from the first week. And pick an MFA method that works in gowns and gloves, such as badge taps or FIDO2 keys, wherever phones are restricted on the floor.

It can when the staffing agency's assignment data reaches your identity governance tool. Access to the EHR then opens before the first shift with a unit-based role and closes when the contract ends, instead of depending on a manager remembering to file a ticket.
