OT Security Issues: Exploring the Causes

done  Increase of connectivity between OT and IT networks

Emotion IconThe occurrence of security threats through the connection between OT and IT network

done  Environmental vulnerabilities for security threats

Emotion IconAn outdated operating system, patch

Emotion IconFrequent use of file-sharing/remote access programs

Emotion IconUse of OT protocols vulnerable to security

done  The inadequate asset visibility specialized for OT  environment

Emotion IconLimitations in applying IT network security techniques to OT networks

Emotion IconAdvanced malware/ransomware targeting specific ICS

Emotion IconLack of security technologies based on OT protocol analysis

done  Need for systematic management across OT and IT

Emotion IconInadequate network visibility and monitoring management

Emotion IconA lack of investment in security threat detection and management

Emotion IconThe absence of systematic and integrated security compliance

Matters to consider upon OT security construction

Security requirements that take into account the internal environment of the OT network must be fulfilled. The availability of facilities must be guaranteed, and the analysis of various OT protocols must support visibility, data transmission, and security threat detection.
