ScreenOS
ScreenOS is a real-time embedded operating system for NetScreen range of hardware firewall devices from Juniper Networks.
Features
Beside transport level security ScreenOS also integrates these flow management applications:
- IP gateway VPN management - ICSA-certified IPSec
- IP packet inspection (low level) for protection against TCP/IP attacks
- Virtualization for network segmentation
2015 "Unauthorized Code" Incident
In December 2015 Juniper Systems announced that they had discovered "unauthorized code" in the ScreenOS software that underlies their NetScreen devices, present from 2012 onwards. They said this allowed unauthorized remote administrative access to NetScreen devices, and also “may allow a knowledgeable attacker who can monitor VPN traffic to decrypt that traffic.”[1] The second vulnerability added to the public debate about the installation of backdoors in cryptographic systems.[2]
