The Committee on National Security Systems (CNSS) model comprises of 27 cells for establishment and evaluation of information security for development of secure systems. In relation to my course, (IA 673) D2L Bright-space, the CNSS model does not only aim at securing security information but also value the security of diverse information such as tests and grades for the course. The 27 cells represent all areas that must be considered for effective security of information (McCumber, 2004). With regards to my course, the CNSS model should address three broad aspects including my personal information, examinations and course results and grades.
Confidentiality: personal information regarding the course should not be available to the public. Intentional or accidental aspects should not expose sensitive information to the public.
Integrity: personal information must be accurate. Neither intentional nor accidental modification of information should happen.
Availability: my personal information should be accessible to allow me to to make changes if need be. The personal data should also be available for the relevant authorities when needed.
Storage: my personal information must be stored in secure servers that are little of invasion.
Processing: the system should allow for reflection of changes to my personal information. Changes should reflect to the system.
Transmission: my personal data should not be susceptible to modification in case of transmission.
Policy: policies regarding access to personal information and data must be clearly defined. For instance, accessibility should only be granted to the administration and me.

Processing: system should allow for performance of operations on results as well as the calculation of grades.
Transmission: results and grades should not be susceptible to alteration or modification during transmissions.
Policy: policies regarding the integrity of course grades and test results must be clearly defined.
Education: both students and staff must understand policies governing confidentiality and integrity of examination results.
Technology: specification of software for calculation and storage of results must be done. Also, the software and hardware used should not be susceptible to tamper and alterations.
