2021: Compatibility with Astra Linux CE release "Eagle" version 2.12.29 and Astra Linux SE release "Smolensk" version 1.6

On January 29, 2021, S-Terra CSP announced that, together with Astra Linux GC, it had completed joint tests of the S-Terra Client A software complex version 4.3 and Astra Linux OS versions 1.6SE and 2.12CE.

S-Terra Client A is a software package designed to protect and filter traffic with session status control on user devices running Astra Linux. The product provides enciphering those transferred data according to the technology IPsec VPN in accordance with the requirements of modern GOST and is certified FSB of Russia as a means () cryptographic information protection according to CIPF class KS1 and KS2.

During the tests, "S-Terra Client A" was installed on workplaces running domestic operating systems of two different versions: Astra Linux Common Edition (release "Eagle" version 2.12.29) and Astra Linux Special Edition (release "Smolensk" version 1.6 with installed Security Update 20200722SE16).

During the test, it was established that "C-Terra Client A," is correctly installed and operates in the specified OS, removal from the OS is carried out successfully. The results of the compatibility study showed the suitability for use of a VPN client with both Astra Linux operating systems and are officially confirmed by Ready for Astra Linux 3675/2020 and 3676/2020 certificates.

Obtaining Ready for Astra Linux status with the C-Terra Client A product means that the range of operating systems for which S-Terra security software is available has become wider, the technical director of S-Terra CSP LLC emphasized. "Another Christopher Gazarov step has been taken to one side. import substitution Organizations using the Russian Astra Linux operating systems on their devices can now use a domestic VPN client to protect access from these devices to their corporate network.

2020: As part of a three-part remote session protection solution

On November 30, 2020, it became known that S-Terra CSP and Aktiv jointly protected access to corporate resources from a remote workplace. The compact and functional solution is made using Russian developments: Rutoken EDS 2.0 Flash electronic identifier, combining the functions of a cryptographic token and a secure flash disk, a certified operating system Astra Linux 1.6 SE and a software VPN client S-Terra Client A designed to work in Astra Linux OS.

Increased security is provided by creating a trusted session and ensuring the isolation of personal and workspaces. In this case, the user needs to perform simple actions: connect Rutoken EDS 2.0 Flash to his computer or laptop, choose to boot from a USB token and pass two-factor authentication to the operating system, gaining access to the necessary resources.

Astra Linux 1.6 SE is pre-installed on a managed protected Flash disk of the Rutoken EDS 2.0 Flash identifier and does not interact with the computer file system, which ensures operating system malware that the device is not used.

During the working session, all network interactions are protected by the VPN client C-Terra Client A, which is pre-installed in Astra Linux 1.6 SE on a secure Flash disk. For enciphering the Russian cryptographic algorithms Magma and Grasshopper are used, the keys are stored in a special protected memory of the Rutoken EDS 2.0 Flash device.

The three-component solution, created in collaboration with Aktiv, provides users with reliable protection when working remotely. This task has become extremely relevant in the last year, - said Andrey Shpakov, Head of the Technical Consulting Department of S-Terra CSP LLC. - It is important that the use of domestic funds allows you to create a trusted environment, provide multifactorial authentication and protect the transmitted data in full compliance with the requirements of Russian legislation.

In these special times, we continue to follow our principles that good decisions are made together and together, and continue to build on partnership. Together with our friends from S-Terra CSP and Astra Linux Group of Companies, we create an ecosystem of trusted complex solutions for secure remote work. We configure standards and technologies for the information security market taking into account the realities of time, "said Pavel Anfimov, Head of Product and Integration at Rutoken Aktiv.

Based on the results of testing, a certificate of compatibility of the electronic identifier Rutoken EDS 2.0 Flash and the software VPN client C-Terra Client A when working in the operating system Astra Linux 1.6 SE^[1].
