CISSP certified daily knowledge points (April 11, 2022)

The following knowledge points are derived from CISSP Official study guide Flash CARD
---------------

【 Knowledge point 】1
Q：What are the benefits of security guards?
ask ： What are the benefits of security personnel ？

A：They are able to adapt and react to any condition or situation, are able to learn and recognize attack patterns, can adjust to a changing environment, and are able to make decisions and judgment calls.
answer ： They can adapt to any condition or situation and respond , Be able to learn and recognize attack patterns , Able to adapt to the changing environment , Able to make decisions and judgments .

【 Knowledge point 】2
Q：What is a Faraday cage?
ask ： What is a Faraday cage ？

A：A Faraday cage is EM blocking enclosure, often a wire mesh that fully surrounds an area on all sides. This metal skin acts as an EMI absorbing capacitor (which is why it's named after Michael Faraday, a pioneer in the field of electromagnetism) that prevents electromagnetic signals (emanations) from exiting or entering the area that the cage encloses.
answer ： Faraday cage is an electromagnetic shielding shell , Usually a wire mesh , Completely surround all aspects of an area . This metal shell acts as EMI Absorption capacitor （ That's why it's a pioneer in the field of electromagnetism · Faraday's name is ）, Prevent electromagnetic signals （ radiation ） Leave or enter the area surrounded by the cage .

【 Knowledge point 】3
Q：What are key concepts of the Mandatory Access Control (MAC) model?
ask ： Enforce access control （MAC） What are the key concepts of the model ？

A：The MAC model uses labels to identify security domains. Subjects need matching labels to access objects. The MAC model enforces the need to know principle and supports a hierarchical environment, a compartmentalized environment, or a combination of both in a hybrid environment. It is frequently referred to as a lattice-based model.
answer ：MAC The model uses tags to identify security domains , A matching tag is required to access the object .MAC The model strengthens “ instructions ” principle , And support layered environments in mixed environments 、 Environment or a combination of both . It is often referred to as a lattice based model .
