The Best Solution For Your Security
Organisational and technical security controls are intended to safeguard against various types of cyberattacks and misuse of assets – including DDoS attacks, mass malware, and targeted ransomware attacks.
The challenge from a security standpoint therefore includes a networked OT infrastructure comprising of highly modern systems alongside 20-30 year old machines. While attackers have so far focused on office IT, it is reasonable to expect that attacks will also be conducted via OT in the future. In any scenario, systematic management for OT security risks is advised.

these are 12 building blocks for OT Security
From Our Perspective
1.
Organisation
Operator is in charge (work management), and there are local contacts
2.
Prioritisation
Risk-based approach based on maximum damage, sensitive data
3.
Inventory
Machine-related assets, ideally in a database (CMDB)
4.
Segmentation
Horizontal (OT – IT with DMZ) and vertical by lines, facilities – NIST reference architecture
5.
Endpoint/Malware Protection
Also, partially possible with legacy systems, scan stick, data locks
6.
Vulnerability Management
Patches in OT are not or hardly possible, focus on systems with access from outside
7.
Employee Awareness
Dedicated OT campaigns to highlight risks as well as proprietary formats
8.
Backups
For larger OT backup tools, processes to create backups after changes
9.
Emergency Concept
Scenarios from single machine failure to all systems with IP address
10.
OT Remote Access
Today, it is necessary, but it is complex to implement. Access restriction, internal enabling, roles/rights, and scheduling are all options
11.
Purchasing Guidelines
Already in specifications, acceptance criteria, demand transparency
12.
Anomaly Detection
Network-based, useful for stable processes, and cost-benefit analysis is crucial
