Data connections can be encrypted at layer 2 or 3 of the ISO/OSI layermodel. SINA L2 Boxes are particularly suited to the rapid and secure transfer of large quantities of data, for example in mirrored data centres, as they produce no overhead and thus offer the highest possible security and full performance with minimum latency. They are therefore preferred for time-critical applications and heavily utilised connections.
Layer 2 encryption is protocol-independent. The encryption at layer 3, on the other hand, is protocol-dependent (IP-based) and thus more flexible in terms of device selection. This means that more complex environments can be mapped at layer 3. It is possible to configure security connections with gateways, stationary and mobile clients. Encryption can be made at both layers with SINA as point-to-point, point-to-multipoint and multipoint-to-multipoint connections.
Public authorities and corporations can select the encryption method best suited to their specific application.
As a VPN gateway, the SINA L3 Box is a key component of the central IT infrastructure in high-security networks. The data exchange between the SINA components is securely transmitted via encrypted VPN tunnels. SINA L3 Boxes connect public authority or corporate networks via the Internet. In addition, access to (terminal) servers by SINA clients is provided via pre-switched SINA L3 Boxes, which serve as cryptographic network accesspoints.
The holistic security concept of the SINA L3 Box comprises a secure SINA OS system platform, smart card technology, IPSec-protected communication and scaled and configured hardware compliant with approval standards.
The SINA L3 Boxes are approved in various configurations for the transmission of classified material up to and including German SECRET, NATO SECRET and
SECRET UE/EU SECRET. They are used, for example, to protect the IVBV and IVBB networks of the German Federal Administration or to ensure secure communication between all of the Ministry of Foreign Affairs' German embassies and the central network nodes in Berlin and Bonn.
The modern workplace needs to be increasingly flexible.There are high expectations in terms of convenience, security and efficiency. However, the reality often looks quite different: regulations regarding internet use and the daily handling of data and documents which serve the required security often are at the expense of convenience and productivity.
With the SINA Workstation as a desktop, notebook or tablet, you can have both security and convenience, online and offline, as you move at will around your trusted working environment. At the same time, you will always have access to data and documents from your working environment: you can use all the functions of your familiar applications and apps, such as email, word processing, presentation slides, spread sheets etc. from anywhere in the world. With a voice and video conference system, you can conduct conversations in real time and your telephone set will become redundant, thus enabling you to reduce telephone costs. Thanks to the tablet's handwriting recognition feature, you always have your notepad with you. Enjoy the mobility and flexibility of your familiar workstation as well as the additional benefit of constant security with the SINA Workstation.
