CISSP (Chapter 1)
Which of the following is the best description pertaining to the “Trusted Computing Base”?A. The term originated from the Orange Book and pertains to firmware.B. The term originated from the Orange Book and addresses the security mechanisms that are only implemented by the operating system.C.

CISSP (Chapter 1)
Which of the following is the best description of the security kernel and the reference monitor?A. The reference monitor is a piece of software that runs on top of the security kernel. The reference monitor is accessed by every security call of the security kernel. The security kernel is too large to test and verify.B. The reference monitor concept is a small program that is not related to the security kernel. It will enforce access rules upon subjects who attempt to access specific objects. This program is regularly used with modern operating systems.C. The reference monitor concept is used strictly for database access control and is one of the key components in maintaining referential integrity within the system. It is impossible for the user to circumvent the reference monitor.D. The reference monitor and security kernel are core components of modern operating systems. They work together to mediate all access between subjects and objects. They should not be able to be circumvented and must be called upon for every access attempt.

Which of the following is an untrue statement?i. Virtual machines can be used to provide secure, isolated sandboxes for running untrusted applications.ii. Virtual machines can be used to create execution environments with resource limits and, given the right schedulers, resource guarantees.iii. Virtualization can be used to simulate networks of independent computers.iv. Virtual machines can be used to run multiple operating systems simultaneously: different versions, or even entirely different systems, which can be on hot standby.A. All of themB.

Which of the following is the best means of transferring information when parties do not have a shared secret and large quantities of sensitive information must be transmitted?A. Use of public key encryption to secure a secret key, and message encryption using the secret keyB. Use of the recipient’s public key for encryption, and decryption based on the recipient’s private keyC. Use of software encryption assisted by a hardware encryption acceleratorD. Use of elliptic curve encryption

John is the security administrator for company X. He has been asked to oversee the installation of a fire suppression sprinkler system, as recent unusually dry weather has increased the likelihood of fire. Fire could potentially cause a great amount of damage to the organization’s assets. The sprinkler system is designed to reduce the impact of fire on the company. In this scenario, fire is considered which of the following?A. VulnerabilityB. ThreatC. RiskD. Countermeasure
