Exposed Management Interface

A firewall, switch or server management interface (SSH, HTTPS admin, RDP, WinRM) is reachable directly from the internet.

Trigger: Attack surface scanning finds a management protocol port open and reachable from an external vantage point.
Risk: Internet-reachable management interfaces are a primary initial-access vector; brute force, credential stuffing and unpatched-management-plane exploits all rely on this exposure existing. AssurIQ weights this heavily in exposure scoring regardless of the device's patch level.

Prerequisites

Confirm which specific interface and port are exposed and to which device
Identify a legitimate administrative access path that does not require the exposed interface
Confirm firewall or cloud security group ownership to make the change

Confirm the exposure with an external scan from outside the customer network.
Identify the rule, NAT mapping or security group entry that allows the exposure.
Restrict the rule to specific trusted source IP ranges, or remove the public mapping entirely.
Provide an alternative access path — VPN, jump host or bastion — for legitimate administrative access.
Re-scan externally to confirm the interface is no longer reachable from the internet.
Record the change and update the attack-surface finding.

External re-scan shows the management port no longer reachable
Legitimate administrators confirm they can still reach the device via the alternative path
Attack Surface no longer lists the asset's exposed management interface

If the restriction blocks a required legitimate access path, add the specific missing source range rather than reopening the interface publicly.
Restore the alternate access path configuration if it was newly introduced and needs adjustment.
