IMPORTING PATCHES TO A SECURE NETWORK

A UK Government Agency

Often you need to transfer patches or system updates from one network to another that have different levels of security. In order to maintain the confidentiality of the downstream server you need to be able to control the flow of data in a secure manner.

Traditional security solutions, such as air-gaps, where there is no physical connection, and firewalls, are no longer secure or efficient enough:

• Air-gaps are labour intensive and prone to poor operational practice, which together introduce vulnerabilities;
• Firewalls cannot be demonstrated to prevent all risk of data flows from the secure network and are therefore not suitable on their own in environments where the impact or threat is high.

A new solution was required that would tackle these issues.

The Nexor solution provides a means to import the patches whilst ensuring data only flows one way, thereby reducing risks of data loss and back communication channels.

The Nexor Data Diode solution was developed through a combination of our accredited professionals, CyberShield Secure services and industry-leading SIXA technology portfolio.
