ENISA publishes its Annual Incidents report which analyses the security incidents causing severe outrages in the Telecom sector in 2015.
The ENISA report provides an overview of the root causes of the incidents and an aggregated level of which services and network assets are impacted in 2015. The key findings are:
-138 major incidents were reported in 2015.
-The most affected service in 2015 was mobile internet and mobile telephony, as the previous years.
-The most frequent causes for incidents are system failures. Software bugs and hardware failures are the most common causes affecting switches and routers, and mobile base stations.
-The total number of incidents caused by malicious actions dropped to 2.5% from 9.6% in 2014
Udo Helmbrecht, ENISA's Executive Director, reminded that: "all parts of society rely on public electronic communications networks and services. Being transparent and discussing the causes of incidents, is essential for risk management and improving the level of security."
