Cybersecurity Program Overview
CXO Nexus is committed to protecting its employees, partners, clients and CXO Nexus from damaging acts that are intentional or unintentional. Effective security is a team effort involving the participation and support of every CXO Nexus user who interacts with data and information systems. Therefore, it is the responsibility of every user to know these policies and to conduct their activities accordingly.
Protecting company information and the systems that collect, process, and maintain this information is of critical importance. Consequently, the security of information systems must include controls and safeguards to offset possible threats, as well as controls to ensure accountability, availability, integrity, and confidentiality of the data:
- Confidentiality – Confidentiality addresses preserving restrictions on information access and disclosure so that access is restricted to only authorized users and services.
- Integrity – Integrity addresses the concern that sensitive data has not been modified or deleted in an unauthorized and undetected manner.
- Availability – Availability addresses ensuring timely and reliable access to and use of information. Security measures must be taken to guard against unauthorized access to, alteration, disclosure or destruction of data and information systems. This also includes against accidental loss or destruction.
