Episode 41 — Control vendor remote access with strict guardrails

Vendor remote access often targets high-value administrative paths, so the exam looks for controls that make these connections rare, provable, and tightly constrained. Start with a simple rule set: access is granted only for defined work, through a hardened gateway that enforces multifactor authentication, device posture checks, and strong encryption. Accounts are unique per individual, never shared, and membership resides in scoped groups tied to least-privilege roles. Sessions traverse jump hosts or bastion services where keystrokes and commands can be captured, and routing forces all traffic through inspected choke points with deny-by-default egress. Change control records why the access is needed and who approved it, while asset inventories identify which systems are eligible targets. Expect to see time-bounded windows for enablement, with automatic disablement at expiration, and logs that correlate identity, device, destination, and activity to create an audit-ready trail.Turn those expectations into operating habits that hold under pressure. When an urgent fix is needed, just-in-time elevation creates the access for the specific ticket while still requiring strong authentication and session recording; after closure, a post-use review confirms activity matched the approved scope. Troubleshooting often reveals shadow pathways: vendor tools that punch outbound tunnels, unmanaged support laptops, or legacy ports opened “temporarily” and never closed. Correct remedies replace ad hoc tools with the sanctioned gateway, remove shared secrets, and instrument alerts for new remote software installations or unexpected outbound flows. Contracts require incident notification and evidence delivery on request, and vendor leaver processes revoke entitlements the same day people change roles. In exam scenarios, the best choices combine prevention, visibility, and accountability so vendor access becomes a narrow, monitored channel that cannot be reused or expanded without detection.
