The testing methodologies described in the question are used to assess the security posture of an information system. The methodology where assessors use all available documentation and work under no constraints to attempt to circumvent the security features of an information system is known as a Penetration Test (C).
A Penetration Test is a simulated cyber-attack on a computer system, network, or web application to identify vulnerabilities that an attacker could exploit. In a penetration test, assessors use a variety of tools and techniques to test the security of the system.
During a Penetration Test, the assessors may attempt to exploit any vulnerability that they discover, including but not limited to: weak passwords, software vulnerabilities, misconfigured devices, and unpatched systems. The goal is to identify weaknesses and provide recommendations to the system owners to remediate the identified vulnerabilities.
A Full Operational Test (A) is a type of security assessment that evaluates the security controls of an information system while it is in operation. This type of testing typically involves simulating various scenarios that an information system might encounter during normal operations, including user interactions, network traffic, and system events.
A Walk-through Test (B) is a type of testing that involves going through a system, application, or process with a user or a group of users to identify potential issues or problems. This type of testing can be used to identify user interface issues, process inefficiencies, or other problems that may impact the overall security of the system.
A Paper Test (D) is a type of testing that involves reviewing documentation related to an information system's security controls, such as policies, procedures, and security plans, to assess the effectiveness of the controls. This type of testing is typically used to evaluate the completeness and effectiveness of the system's security controls.
In summary, the testing methodology where assessors use all available documentation and work under no constraints to attempt to circumvent the security features of an information system is known as a Penetration Test.
