Owl 4.0SFF Cross-Domain Solution

In a 1U (1.75") high rackmountable chassis, the Owl 4.0 SFF supports cross domain data flows for file transfers in a lower-to-higher security direction. Within the single chassis, Owl 4.0 SFF integrates complete Send-only and Receive-only server engines connected via Owl proprietary DualDiode® Technology. Send & Receive servers are connected by an internal fiber optic link operating at 155Mbps.

Extensive data filtering and content examination utilities may be enforced at either the Send-only or Receive servers, or both. Owl 4.0 SFF provides a certifiable one-way solution with a base set of capabilities -- configurable as enabled or disabled -- as dictated by changing mission and security requirements, leading to re-use among programs that require similar capabilities.

In addition to satisfying site-specific requirements, Owl 4.0 SFF is designed to provide a non site-specific one-way CDS architecture with a base set of security features. Modular data filters managed by the Owl File Integrity Agent (OFIA) ensure integrity of data passing onto the destination domain. Owl 4.0 employs Owl Remote File Transfer Service RFTS for efficient and authenticated transport of files as TCP/IP streams -- to the cross domain solution from source, and from the CDS to the user destination.

Since data type and data filter requirements are largely determined by program and site, the OFIA application programming interface is designed to accommodate third party data filter software applications. By default, it is equipped with antivirus scanning software (i.e., ClamAV) and a file type checking method that are designed to block transfer of malware and executable code, respectively.
