Protect SCADA, PLC, DCS, dan industrial control systems dari cyber attacks yang mengancam keselamatan, operasional produksi, dan infrastruktur energi nasional
OT/ICS Security Expertise:
Manufaktur, energi (power plants, oil & gas), air/water treatment, telekomunikasi = infrastruktur kritis nasional (IKN). Cyber attack pada SCADA/ICS tidak hanya disrupt produksi—tetapi mengancam keselamatan pekerja, lingkungan, dan keberlangsungan negara. Stuxnet, Triton, Colonial Pipeline = warning bahwa OT/ICS adalah prime target untuk nation-state actors dan cyber criminals.
SCADA, PLC, DCS di pabrik/power plants installed 20-30 tahun lalu—running on Windows XP, unpatched firmware, hardcoded passwords. Designed for air-gapped isolation, bukan connected networks. Now connected ke IT untuk remote monitoring = exposed to cyber threats.
Manufacturing plants operate 24/7 continuous production. Taking system offline untuk security patching = millions in lost revenue. OT systems can't reboot tanpa stopping assembly lines. Result: vulnerabilities remain unpatched for years.
Compromised safety instrumented systems (SIS) dapat cause explosions, chemical leaks, equipment damage, worker injuries/deaths. Triton malware specifically targeted safety systems di petrochemical plant. Cyber security = worker safety.
Industry 4.0, IoT sensors, remote monitoring—OT networks now connected ke IT corporate networks dan internet. Lateral movement dari compromised IT workstation ke OT control systems. Air gap no longer exists—convergence = new risks.
Equipment vendors, system integrators, maintenance contractors memiliki persistent VPN access ke OT networks untuk remote support. Compromised vendor credentials = direct access ke SCADA systems. Supply chain = weak link.
Power plants, oil refineries, water treatment facilities = strategic targets untuk nation-state APT groups. Pre-positioning for potential cyber warfare, economic sabotage, atau geopolitical leverage. Stuxnet, BlackEnergy, Triton = state-sponsored attacks.
Ransomware targeting manufacturing—encryption SCADA, HMI screens, engineering workstations = instant production halt. Colonial Pipeline, JBS Foods, Norsk Hydro—all paid millions to restore operations. Downtime = millions per hour.
Triton malware specifically targeted Safety Instrumented Systems (SIS) di petrochemical plant—designed to cause explosions. Manipulation of safety PLCs, disabling emergency shutdown systems = worker deaths, environmental disaster.
Attackers inject malicious code into PLC firmware (Stuxnet did this)—causing equipment malfunction, production defects, atau physical damage. Firmware rootkits difficult to detect, persist through reboots, evade traditional security tools.
Compromise IT network (phishing, malware) → pivot to OT network via interconnections, shared credentials, weak segmentation. Once in OT, attackers can monitor/manipulate industrial processes. IT-OT convergence = IT vulnerabilities become OT risks.
Compromised equipment vendors atau system integrators insert backdoors into SCADA software, PLC firmware, HMI applications during installation/updates. Vendor remote access = persistent foothold. SolarWinds-style attacks on industrial suppliers.
BlackEnergy malware caused Ukraine power outage (2015)—230,000 people without electricity. Attackers opened circuit breakers remotely, wiped SCADA systems. Critical infrastructure disruption = geopolitical weapon, economic damage, public panic.
Comprehensive assessment OT infrastructure—SCADA, PLC, DCS, HMI, historian servers. Identify vulnerabilities, misconfigurations, weak access controls. Non-disruptive testing methodology untuk avoid production impact.
Design & implement Purdue Model network segmentation—isolate OT dari IT, create security zones (Level 0-4), deploy industrial firewalls, unidirectional gateways untuk prevent lateral movement IT→OT.
Deploy OT-specific monitoring tools—network traffic analysis (ICS protocols: Modbus, DNP3, OPC), behavioral anomaly detection, asset visibility. Detect unauthorized PLC programming, firmware changes, suspicious commands.
Secure vendor remote access—implement privileged access management (PAM), multi-factor authentication, session monitoring untuk vendor VPNs. Vendor security assessments, contractual security requirements, audit vendor activities.
Implement IEC 62443 industrial cybersecurity standard—foundational requirements, system requirements, component requirements. Gap assessment, security level target definition, compliance roadmap untuk certification.
Develop OT-specific incident response playbooks—ransomware on SCADA, PLC compromise, safety system sabotage scenarios. Backup/restore procedures, failover to manual operations, coordination dengan safety teams.
