How Is a Cross-Domain System Different from Other Security Appliances?

A CDS differs from other security appliances such as firewalls, web application firewalls (WAFs), and intrusion detection or prevention systems. In addition to providing physical, network, and logical isolation between domains, cross-domain solutions offer additional security mechanisms. These additional mechanisms include virus scanning, auditing and logging, and deep content inspection in a single solution. When the CDS is included in a larger security program, these capabilities help prevent both exploitation and data leakage. By design, CDS systems are intended to fail data passing if anything is suspect or not recognizable in the flow.
