How is a vulnerability assessment different from a penetration test for a mining operator?

A vulnerability assessment is the recurring, broad-coverage layer. It runs on a schedule across IT and mine OT and flags known vulnerabilities, missing patches, weak configurations, and unmapped assets at scale. A penetration test is a deeper, point-in-time exercise that tries to exploit a defined scope to prove real impact. Most operators run vulnerability assessment continuously to keep an accurate picture of exposure, and use a penetration test periodically on the parts of the estate that justify it.

Is it safe to run vulnerability scanning near live mine OT?

Active scanning, the kind that sends probe packets and waits for a response, is not something we run against a live fleet-management network, a processing ICS, or a blast control system. Many of these devices were never built to handle unexpected traffic and can fault or behave unpredictably when they receive it. On the OT side we use passive discovery and, where a system supports it safely, credentialed checks that read configuration without probing, so the assessment builds an accurate inventory without sending anything disruptive into the control network.

How often should a mining operator run a vulnerability assessment?

IT assets are typically scanned monthly or continuously depending on exposure. Mine OT assets are assessed less frequently, often quarterly or aligned to a maintenance window, since even passive discovery is scheduled with the operations team rather than run without coordination. The right cadence depends on how much of the estate, especially remote sites and internet-reachable OT paths, has never been assessed at all, which for many operators is still most of it.

What is actually in scope across a mining operation?

The corporate IT side gets standard authenticated and unauthenticated scanning of servers, workstations, cloud workloads, and applications. The OT side, autonomous haulage and fleet management, the remote operations centre, ore-processing ICS, and environmental monitoring, gets passive discovery and configuration review instead. The estate almost always includes the resource and geological data stores and the remote-monitoring paths that connect mine OT to the internet, which is where a purely IT-focused scan misses the most consequential findings.

Vulnerability assessment mining Indonesia

Vulnerability assessment across a mining operation cannot mean pointing a scanner at every IP address and letting it run, the way it might on a corporate network. Part of the estate is corporate IT that can absorb an aggressive scan without consequence, and part of it is mine OT, autonomous haulage, a remote operations centre, ore-processing ICS, where an unexpected packet can fault a controller that has no business faulting. It is also a recurring exercise rather than a one-off, which is what separates it from a single penetration test. This page covers how vulnerability assessment works across both sides of a mining estate. For how vulnerability assessment works in general, see our Vulnerability Assessment service page.

Why vulnerability assessment matters in mining

The corporate IT side of a mining operator looks like most other enterprise IT and tolerates scanning without much thought. The rest of the estate, spread across remote sites and increasingly connected to the internet, is where the assessment earns its place.

Unmapped internet-reachable OT paths

Remote monitoring has connected mine OT to the internet through paths operators have often not fully mapped. A vulnerability assessment that reaches into the OT side is one of the more direct ways to find those connections before someone else does, rather than assuming the asset inventory is complete.

Asset discovery across remote sites

A mining operator's estate is spread across pits, processing plants, and remote sites that rarely share one accurate inventory. Recurring assessment keeps that inventory honest, which matters more here than in a single-building enterprise where the asset list drifts far less.

Fragile ICS that needs safe scanning

PLCs and RTUs on haulage, processing, and blast control networks were built for control reliability, not for handling unexpected traffic. An active scan that would be routine against a server can fault a controller, with a physical consequence rather than just a logged error, so these assets need a scanning method matched to what they can tolerate.

Reporting integrity exposure

The systems and data stores behind ESDM environmental and production reporting are part of the scope for a reason. An attacker who can reach and alter those records creates regulatory and legal exposure, and a recurring assessment keeps an eye on where those systems sit relative to everything else.

Vulnerability assessment or penetration test

The two are complementary, not interchangeable, and it is worth keeping them separate rather than treating any security check as one activity.

	Vulnerability assessment	Penetration test
What it does	Identifies known vulnerabilities, missing patches, weak configurations, and unmapped assets at scale	Attempts to exploit a defined scope to prove real business or operational impact
Coverage	Broad, across IT and mine OT	Deep, on a focused target such as one site or system
Cadence	Recurring, on a schedule	Point-in-time, periodic
Approach near OT	Passive discovery and safe credentialed checks, no active probing of live control systems	Tightly scoped and authorised, active techniques avoided against live OT

How we deliver it across IT and OT

The estate gets one assessment programme but two distinct methods, matched to what each side of the network can tolerate.

Authenticated and unauthenticated scanning of IT servers and endpointsCloud workload and application vulnerability scanningPassive network discovery for mine OT asset inventoryFirmware version checks against known CVEs for PLCs and RTUs, without active probingRemote-monitoring path and IT/OT boundary reviewResource and geological data store exposure review

Inventory IT and OT assets across the pit, processing plant, and remote sites→Scan IT assets on a recurring schedule, actively and safely→Run passive discovery and safe credentialed checks on mine OT, scheduled with the operations team→Assess each finding for exploitability and operational impact, not CVSS score alone→Report and track remediation across both IT and OT

Findings are not ranked by CVSS score alone, because OT context regularly shifts what actually carries risk. A finding on a controller tied to autonomous haulage or a safety-adjacent process gets weighed differently than the same technical finding on an isolated reporting workstation, even when the raw score would suggest otherwise. Scanning near mine OT is always coordinated with remote operations rather than run in isolation.

For the deeper, point-in-time review of OT architecture, segmentation, and IEC 62443 alignment rather than recurring scanning, see our OT and ICS security assessment for Indonesian mining operators page. For the wider OT and ICS threat model and VAPT approach, our OT and ICS security in Indonesia guide covers that ground in general.

Sector-specific figures for OT vulnerability counts or remediation timelines in Indonesian mining are not backed by a primary source we could verify, so this page leads with the methodology rather than an invented number. What holds across nickel, coal, and bauxite operators is that large parts of the OT estate, particularly at remote sites, have never been assessed even at the passive level, and that is usually the more useful starting point than debating scan frequency.

If most of your mine OT has never been assessed, even non-intrusively, our team can help you scope where to start.
