Contractors, temps and the visiting engineer
Contractors, temps and the visiting engineer. What it costs, who decides, and what usually goes wrong.
Where time records form part of the operating evidence, employee attendance tracker offers a related workflow reference without replacing the control owner’s review.
For an independent reference point, see CISA Insider Threat Mitigation Guide.
Who this covers
Four kinds of person who are not your employees
The equipment vendor's engineer, on site with a laptop, plugging into a machine.
The remote support session, opened for a fault and sometimes left open.
Agency and temporary staff, on assignments measured in weeks, arriving faster than any provisioning process.
Professional services: consultants, auditors, integrators, each needing something.
All four touch covered information in the ordinary course of work and all four sit outside the arrangements built for employees.
Provisioning at speed
The tension, stated honestly
A machine is down, the engineer is here, and the account request will take two days. Every business resolves this the same way and the resolution is a shared account somebody set up years ago.
The fix is not a faster approval chain. It is a pre-agreed arrangement: a named, time-limited account per vendor, created in advance, enabled on request and disabled automatically.
That takes an afternoon to set up per vendor and removes the pressure that produces the shared account.
The escort
Somebody stays with them
For physical visits, an escort who knows what the visitor is doing and stays present. Not surveillance: presence, and a record that somebody was there.
It is the cheapest control in this entry and it is also the one that catches the ordinary problem, which is a well-meaning engineer copying a file to their own laptop to look at later.
Contracts
Three clauses worth having
With the equipment vendor: what their engineers may connect, what they may copy, and what happens to anything they take away. With the labour supplier: who is responsible for background checks and for training, and what they are told about your requirements. With professional services: confidentiality, and the same offboarding obligations as anybody else.
None is unusual and none appears by default.
Training them
Somebody has to, and it is usually you
A contractor's own employer trains them on their own environment, not on yours. A ten-minute induction covering what may be copied, what may be connected, and who to tell if something goes wrong is worth more than a clause about it.
Record it, for the same reason employee training is recorded.
Remote sessions
Opened deliberately, closed the same day
Support connections that persist are one of the most common findings in this area, and they persist because nobody owns closing them. Attach the closure to the ticket rather than to somebody's intention, and review what is open monthly.
The review takes ten minutes and reliably finds something.
The register
Know who has access who is not on payroll
A list, reviewed quarterly, of every non-employee with access to anything. Most suppliers cannot produce this and an assessor will ask for it.
Building it is a morning and it usually finds two or three accounts belonging to people who finished an engagement a year ago.
The badge that never expires
Physical access, reviewed with the digital kind
Contractor badges outlive contracts more reliably than accounts do, because nobody receives a notification. Review them on the same quarterly cycle as the access register and against the same list.
The engineer who fixes it fastest
Convenience arrives with a reputation
The vendor engineer everybody likes is frequently the one who works around your controls to get the machine running, and is thanked for it. Raise it with their employer rather than with them, and put the expectation in the contract before the next visit.
