Assume environment.

General Principle 1- Minimize the number of high-consequence targets includes the following principles and practices:

The Data and Analysis Center for Software (DACS) has identified three general principles for software assurance that serve as a framework to categorize various secure design principles. The three principles are:

  1. General Principle 1: Minimize the attack surface area by making the software and its environment as small and simple as possible. This principle includes the following practices:

A. Principle of least privilege: This practice suggests that software should be designed so that it operates with the minimum privileges necessary to accomplish its tasks. This helps to reduce the impact of a security breach, as an attacker who gains access to the software will only have access to a limited set of resources.

B. Principle of separation of privileges, duties, and roles: This practice suggests that software should be designed so that different users or processes have different levels of access to resources. This helps to prevent a single compromised user or process from gaining access to sensitive resources.

C. Simplify the design: This practice suggests that software should be designed as simply as possible, with fewer features and components, to minimize the number of potential vulnerabilities.

  1. General Principle 2: Use secure defaults and configuration options. This principle suggests that software should be designed with secure defaults and configuration options, to reduce the need for manual configuration and to prevent misconfiguration.

  2. General Principle 3: Use secure coding practices. This principle suggests that software should be designed and coded using secure practices, such as input validation, error handling, and secure communication protocols.

Therefore, the correct answers to the question are A. Principle of separation of privileges, duties, and roles and D. Principle of least privilege, as both of these practices fall under General Principle 1: Minimize the attack surface area by making the software and its environment as small and simple as possible.
