Introduction

The “4 C’s” of Cross Domain Solutions (CDSs) refer to the primary objectives that these systems seek to accomplish. The four Cs are:

Controlled Access

CDSs aim to provide controlled information access between different security domains. They are designed to allow the secure transfer of information while enforcing strict access controls to ensure that only authorized users can access the information.

Confidentiality

CDSs aim to maintain the confidentiality of information by preventing its unauthorized disclosure. This is accomplished via a variety of technical controls, including encryption, access controls, and monitoring.

Integrity

CDSs aim to maintain the integrity of information by ensuring that it is not tampered with or altered in any way during transfer. Several technical controls, including digital signatures and hashing, accomplish this.

Availability

Conclusion

By achieving these four characteristics, CDSs can facilitate the secure exchange of information between different security domains while minimizing the risk of unauthorized access, disclosure, or tampering.
