Conclusions and recommendations

[relemedf5w023]

For years, security vendors have debated the cognitive differences between IT and OT when it comes to security. Our research shows that campus networks bring a new factor to the table: communications technology, or CT. To maintain a campus network, IT/OT staff must also have CT knowledge to ensure its security.

Here is a list of key measures to protect the campus network and prevent threats from affecting the production control network:

Use VPN or IPsec to protect remote georgia mobile database channels, including remote sites and base stations. It is important to remember that LTE and 5G do not provide automatic encryption;
use application-level encryption such as HTTPS, MQTTS, LDAPS, encrypted VNC, RDP v10 and secure industrial protocols such as S7Comm-Plus;
use cybersecurity tools that understand the underlying network protocols (Modbus and others);
Use EDR, XDR or MDR to monitor for possible attacks and lateral movement within the campus as well as within the container backbone network;
ensure network segmentation using VLAN or SDN;
Keep servers, routers, and base stations up to date. Since many components of the core network run on Linux, pay special attention to Linux vulnerability reports;
Invest in campus network anomaly detection products that provide a reliable way to weed out unlisted device/SIM pairs.
