The Southern Cross cable network underwent a major upgrade project to increase its capacity and deploy new technologies. The upgrade included:
1) Implementing a unified layer 0 and 1 platform to provide both submarine and terrestrial segments as a seamless network, minimizing conversions with ROADMs and wavelength switching.
2) Upgrading all seven submarine segments and five terrestrial segments with 40G and 100G coherent wavelengths for a total of 2.8T of new capacity.
3) Deploying a single service platform to efficiently switch, groom, and protect traffic across protocols from a single node using intelligent switching.
This talk will provide an in-depth treatment of satellite telephony networks from a security perspective. The overall system seems secure, but in reality, it cannot be expected to be fully reliable.
We will briefly cover the satellite mobile system architecture, then discuss GMR (GEO-Mobile Radio) system elements, e.g. GSS (Gateway Station Subsystem), MES (Mobile Earth Station), AOC (Advanced Operation Center), and TCS (Traffic Control Subsystem) for GMR-1 systems and NCC (Network Control Center), GW (Gateway), SCF (Satellite Control Facility) and CMIS (Customer Management Information System) for GMR-2 systems.
From there, we will discuss the security issues of GMR system as it shares similar vulnerabilities with GSM–GMR is derived from the terrestrial digital cellular standard GSM and support access to GSM core networks, along with some interesting demos.
Time permitting, a question and answer session at the end of the presentation will allow participants to cover any additional issues in satellite telephony system they’d like to discuss.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
