The Biba model is a formal state transition system of computer security policy that describes a set of access control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity. The model is designed so that subjects may not corrupt data in a level ranked higher than the subject, or be corrupted by data from a lower level than the subject.

NIST has developed a suite of documents for conducting Certification & Accreditation (C & A). These documents are as follows: NIST Special Publication 800-37: This document is a guide for the security certification and accreditation of Federal Information Systems. NIST Special Publication 800-53: This document provides a guideline for security controls for Federal Information Systems. NIST Special Publication 800-53A. This document consists of techniques and procedures for verifying the effectiveness of security controls in Federal Information System. NIST Special Publication 800-59: This document is a guideline for identifying an information system as a National Security System. NIST Special Publication 800-60: This document is a guide for mapping types of information and information systems to security objectives and risk levels.

According to the question, you are hiring a local expert team for casting the column. As you have transferred your risk to a third party, this is the transference risk response that you have adopted. Transference is a strategy to mitigate negative risks or threats. In this strategy, consequences and the ownership of a risk is transferred to a third party. This strategy does not eliminate the risk but transfers responsibility of managing the risk to another party. Insurance is an example of transference. Answer: C is incorrect. Mitigation is a risk response planning technique associated with threats that seeks to reduce the probability of occurrence or impact of a risk to below an acceptable threshold. Risk mitigation involves taking early action to reduce the probability and impact of a risk occurring on the project. Adopting less complex processes, conducting more tests, or choosing a more stable supplier are examples of mitigation actions. Answer: A is incorrect. Avoidance involves changing the project management plan to eliminate the threat entirely. Answer: B is incorrect. Acceptance response is a part of Risk Response planning process. Acceptance response delineates that the project plan will not be changed to deal with the risk. Management may develop a contingency plan if the risk does occur. Acceptance response to a risk event is a strategy that can be used for risks that pose either threats or opportunities. Acceptance response can be of two types: Passive acceptance: It is a strategy in which no plans are made to try or avoid or mitigate the risk. Active acceptance: Such responses include developing contingency reserves to deal with risks, in case they occur. Acceptance is the only response for both threats and opportunities.

Assessment, monitoring, and assurance determines the necessary compliance that are offered by risk management practices and assessment of risk levels.
