CNSSI 1253 is a directive developed by the Committee on National Security Systems (CNSS) that outlines the requirements and guidelines for specialized skills training for federal employees involved in national security systems. The directive ensures that the employees possess the necessary skills, knowledge, and proficiency required for the particular national security systems they work with. The specialized skills training covers a wide range of topics, including information assurance, system engineering, cryptography, and cybersecurity, among others.

Cyber Engineering refers to the discipline that integrates principles of engineering and computer science to design, develop, and maintain secure systems and networks. This skill encompasses the analysis of vulnerabilities, implementation of security measures, and the development of protocols to protect information and infrastructure from cyber threats. Knowledge of Cyber Engineering is used to create resilient systems that ensure data integrity, confidentiality, and availability, while also addressing compliance with regulatory standards.

Department Of Defense (DoD) 8510 refers to the framework used to manage information system security authorization and compliance requirements within defense organizations. It is applied to assess system controls, document security status, and support approval decisions for operating systems and applications. The skill supports ongoing monitoring, risk management, and coordination among security, compliance, and operations teams.

DoD Cybersecurity Framework (DCF) refers to a set of structured guidelines and standards established by the U.S. Department of Defense for securing information systems. It enables the user to assess, manage, and mitigate cybersecurity risks across DoD operations and assets. The framework supports compliance with federal mandates by providing a common language and methodology for implementing security controls. It is applied in defense-related environments to ensure the confidentiality, integrity, and availability of critical information systems.

IAM Level II Certification refers to intermediate proficiency in identity and access management principles, controls, and procedures. It is applied in work settings to support user access administration, authentication processes, and access review activities. The skill indicates the ability to follow established security policies and help maintain appropriate access to systems and information.
