Command-Level Security Gaps in Industrial Protocols Exploited

• •Industrial protocols like Modbus lack authentication, exposing critical infrastructure to risks.
• •PacketViper offers command-level inspection to prevent unauthorized commands in real-time.
• •The solution is agentless, requiring no changes to existing PLCs or SCADA systems.

PacketViper has highlighted significant vulnerabilities in industrial protocols like Modbus, which lack authentication and authorization, making them susceptible to unauthorized commands. These protocols are widely used in critical infrastructure sectors such as water, power, and manufacturing. Attackers can exploit these vulnerabilities through compromised credentials or unauthorized devices, issuing commands that appear legitimate at the port level. PacketViper's solution provides command-level inspection and enforcement to mitigate these risks in real-time. The technology decodes commands to understand their context and applies policies to block unauthorized actions. This inline approach ensures that only legitimate commands are executed, protecting physical processes and safety margins. Current deployments are agentless, requiring no changes to existing systems, and focus on monitoring and blocking unauthorized write commands.
