ICS threats to cybersecurity

The threats of anomalies in Industrial Control Systems

With a Rhebo Industrial Security Assessment, industrial companies and operators of critical infrastructure gain complete transparency of their Industrial Control System (ICS). All suspicious componentes, connections and communication processes are identified. The results enable those responsible for cybersecurity to immediately eliminate threats and to secure their ICS.

‍The following examples showcase typical results from Rhebo audits and the identified anomalies.

‍Also, explore the technical error state anomalies that threaten the productivity of automated manufacturing companies.

Preventing Malware Infection

Analysis

Rhebo Industrial Protector registered multiple communication via the protocol types VNC, NetBIOS and SMB. The protocols are typically used by Windows devices for remote configuration and file sharing.

‍

Their usage is usually not wanted in industrial networks.

Security Threat

The protocols are often used by malware (e.g. NotPetya and WannaCry). If the affected devices have direct or indirect access to the Internet, the ICS is at risk of compromise or infection.‍

Threats:

  • financial loss due to production downtime
  • power failure due to blackout
  • system recovery and repair costs
