A bad plant condition and interferers may degrade the communication between CM and CMTS. Luckily though there is lot of data that can be monitored to detect quite some issues.
Thanks to the power of the cloud, it's easier than ever to break the encryption as used with DOCSIS and EuroDOCSIS. Since version 3.0 of the standard it's also much easier for operators to counter these attacks, but despite having arrived at DOCSIS 3.1 already, not everyone already implements the DOCSIS 3.0 security.
