OT & IoT Security
Transparency and security in IT, IoT and OT (ICS) environmentsSOLUTIONS / SECURITY / OT & IOT SECURITY
How OT security differs from IT security
Digitization caught all areas of the economy and society. Therefore, sooner or later almost every company will have to deal with the topics of OT (Operational Technology), IoT and Industry 4.0. However, they not only offer immense potential – they also harbor great risks.
For a long time, operational technology (OT) was strictly separated from the IT network and the outside world (air gap). With the increasing digitization and spread of IoT, the two worlds are growing ever closer together and are therefore being targeted by attackers.
Challenges
- Maintenance access
- Increasing number of network devices
- Integration of the supply chain
- Flat networks
- Weak authentication
- No data encryption
- Insecure old ICS protocols
- Legacy or unpatched systems
- Lack of visibility within ICS networks
- Shadow OT devices
- Lack of asset management
- No proactive threat monitoring
The secret of a successful common security strategy for IT and OT systems lies in knowing their different needs. Industrial companies need IT security solutions that have been specially designed for use in the OT area – robust, smart, comprehensive.
If cybercriminals succeed in compromising ICS systems, this can not only impair productivity, lead to financial losses and a risk to the brand’s reputation; Malfunctions could also endanger the physical safety of employees.
Measures for securing OT systems
1. Perform risk analysis
What should be protected and against what should it be protected? The aim is to identify and evaluate the most important dangers. The risk analysis should be carried out specifically for a company, a production environment, a system, a plant or a machine. This also includes getting an understanding of potential attack vectors such as uncontrolled remote access. The higher the risk rating for a system, the more each access to or through this system is checked.
2. Visibility – create visibility
It is important to make fully visible what is happening in the network. In order to protect yourself against cyber attacks, you need a deeper insight into your own infrastructure and network activities. Every device in the network must be identified, classified and checked for known vulnerabilities.
3. Segmentation – create network zones
A key aspect of ensuring security in the OT environment is the segmentation of the operator network into individual, separate segments. Internal segmentation firewalls are used to set up and control network segments quickly and dynamically. They also check all data traffic when the segment limits are exceeded.
4. Control access
Authentication and authorization ensure that only authorized employees / maintenance companies have access to machines and systems.
5. Identify and stop abnormal behavior
In addition, the communication of these assets must be continuously monitored. Anomalous behavior can be identified and finally prevented on the basis of a “normal state”.
