Why each option
Common Criteria EAL 7 represents the most rigorous assurance level, requiring formal verification of the design and extensive independent testing.
EAL 1 (Functionally Tested) is the lowest assurance level, providing basic assurance.
EAL 3 (Methodically Tested and Checked) involves a moderate level of assurance through testing and architectural design review.
EAL 5 (Semiformally Designed and Tested) requires a higher level of assurance with a semiformally designed architectural design and rigorous testing.
EAL 7 (Formally Verified Design and Tested) is the highest assurance level under Common Criteria, indicating that the Target of Evaluation (TOE) has undergone a rigorous formal verification of its design and extensive independent testing.
