OSI Security Architecture: Questions And Answers
Question 1.1
The OSI Security Architecture is an outline that gives a sorted-out method for characterizing the prerequisites for security and describing the techniques to filling those requirements.
Question 1.2
Active security threats include data transmitted being modified and efforts to gain unauthorized access to computer systems.
Passive security threats are usually associated with eavesdropping on, or, monitoring, transmissions. Electronic mail, client or server exchanges and file transfers are examples.
Question 1.3

Passive security attacks: release of message contents and traffic analysis.

Fail-safe defaults: This principle says that access decisions should be based on permission rather than exclusion.
Complete mediation: This principle says that every access must be checked against the access control mechanism.
Open design: This principle says that the design of a security mechanism should be open rather than secret
Separation of privilege: This principle says can be defined as a practice in which multiple privilege attributes are required to achieve access to a restricted resource.
Least privilege: This standard says that every procedure and each client of the system should operate using the least set of freedoms necessary to perform the duty
Least common mechanism:
This principle says that the design should to limit the capacities shared by various clients, giving common security. This principle helps reduce the number of unintended communication paths and reduces the amount of hardware and software on which all users

A collection $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}}$ is monotone if $B\in\mathbb{A}$ and $B\subseteq C$ implies $C\in\mathbb{A}$. An access structure is a monotone collection $\mathbb{A}$ of non-empty subsets of $\{P_1,P_2,...,P_n\}$, i.e., $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}} \setminus\{\emptyset\}$. The sets in $\mathbb{A}$ are called the authorized sets, and the sets not in $\mathbb{A}$ are called the unauthorized sets}. In our settings, attributes will play the role of the parties such that the access structure $\mathbb{A}$ will contain the authorized
