Protocols and network security in ICS infrastructures
In the last years the growth of Internet and the number of devices with connectivity and process capacity have brought with them the need to adjust the corresponding security measures. Nevertheless, these security adjustments have not always grown at the same pace as the new technologies and the new devices. The Industrial Control System infrastructures are no exception and they find themselves equally affected by this evolutionary movement, if not even more so, given that the industrial control platforms used, and specifically communication protocols, are, in the main, outdated and intrinsically weak by design.
The guide discusses some of the most representative communication protocols Industrial Control Systems indicating the security aspects and additional measures necessary to the weaknesses found
