d. Users at a lower level of integrity may not write information to a higher level of integrity

Answers

Answer 1

a. Users at a higher level of integrity may not read information at a lower level of integrity

d. Users at a lower level of integrity may not write information to a higher level of integrity

The Biba Integrity model is a formal model for computer security that addresses the integrity of data. It consists of two rules:

a. The *integrity no-read-up rule, which states that a subject (user or process) at a higher integrity level may not read data at a lower integrity level.

b. The *integrity no-write-down rule, which states that a subject at a lower integrity level may not write data to a higher integrity level.

These rules are designed to prevent unauthorized modifications of data and ensure that data is only accessed by authorized users or processes. The Biba Integrity model complements the Bell-LaPadula Confidentiality model, which focuses on confidentiality rather than integrity.

Which of the following changes helped General electric improve product delivery from its circuit-breaker division?
A. developing individualized custom-designed products.
B. Introducing a more streamlined management system.
C. Consolidating manufacturing areas.
D. Instituting an automated design system

Answers

Answer:

The answer is D. Instituting an automated design system.

General Electric's circuit-breaker division was able to improve product delivery by instituting an automated design system. This system allowed engineers to design and test new products more quickly and efficiently. As a result, the division was able to bring new products to market faster and meet customer demand more effectively.

The other options are not correct because they do not directly address the issue of product delivery. Developing individualized custom-designed products may increase customer satisfaction, but it will not necessarily improve product delivery. Introducing a more streamlined management system may improve efficiency, but it will not necessarily improve product delivery. Consolidating manufacturing areas may reduce costs, but it will not necessarily improve product delivery.

The maximum time allowed for the Sprint planning for a 2 week Sprint is_________.

Answers

The maximum time allowed for the Sprint planning for a 2 week Sprint can vary depending on the size and complexity of the project. However, the general recommendation is that the Sprint planning should not take more than 8 hours for a 2 week Sprint.

This allows the Scrum team to adequately plan and prioritize the work that needs to be done during the Sprint.During the Sprint planning, the Product Owner and the Development team work together to define the Sprint goal and identify the work that needs to be completed during the Sprint. The Product Owner presents the highest priority items from the product backlog and the Development team estimates the effort required to complete each item. Based on these estimates, the Development team commits to completing a certain amount of work during the Sprint.The time-box for the Sprint planning is typically set at 8 hours for a 2 week Sprint, but it is important to note that this time can be adjusted based on the needs of the team. If the team needs more time to adequately plan and prioritize the work, they can request additional time from the Scrum Master. However, it is important to ensure that the time-box is not extended excessively as it can lead to delays in the project and impact the team's ability to deliver the work within the Sprint.
