Kaspersky Endpoint Security for Linux Space Edition

History

2025: Product Announcement

Kaspersky Lab has developed a specialized solution to protect the satellite platform of the RUVDSSat1 hosting provider RUVDS from cyber threats. The software is called Kaspersky Endpoint Security for Linux (KESL) - Space Edition and will ensure the security of the spacecraft throughout its mission. This was reported in the press service of Kaspersky Lab on December 12, 2025.

The software is based on KESL technologies, taking into account special performance requirements in conditions of limited computing resources in orbit. Kaspersky Lab has adapted its technologies to the specifics of the space platform in order to protect the payload that the hosting provider places on the satellite.

A separate Raspberry Pi Zero microcomputer with a processor frequency of 1 GHz and 512 MB of RAM is responsible for solving IT problems in the spacecraft. The company has adapted its security technologies for this platform, taking into account severe restrictions on computing resources.

The development of a protective solution for space required a special approach due to the minimum capacity of the on-board computer. The software should work efficiently with an extremely limited amount of RAM and a low processor frequency. This is fundamentally different from the working conditions of security solutions on Earth servers.

The project has a research character and is focused on a wide variety of experts and enthusiasts of space exploration. At the same time, the hosting provider does not exclude the possibility of providing the computing power of the satellite on a commercial basis. The minimum period of operation of the RUVDSSat1 in orbit will be one year.

The openness of the project to the scientific community will allow researchers to study the features of computing systems in space. The data obtained can be used to develop technologies for protecting orbiters and improve cybersecurity methods in space.^[1]
