Chapter 23: Problem 6

Discuss the system of propagation of privileges and the restraints imposed by horizontal and vertical propagation limits.

Short Answer

Expert verified
Privilege Propagation is the extension of a user's permissions in a system. Horizontal propagation occurs at the same authority level, like one admin getting the privileges of another. Vertical propagation comes from a lower authority level acquiring the privileges of a higher one, for example, a user gaining admin rights. Both types of propagation have limits to prevent unauthorized access and maintain system security.

Step by step solution

01

Understanding Privilege Propagation

Privilege Propagation is a mechanism by which a user's permissions or privileges are extended or transferred within a system. It's a foundational concept in access control, often employed in IT and network security systems.
02

Explaining Horizontal Propagation

Horizontal privilege propagation refers to the transfer of permissions at the same level of authority. For instance, if there are multiple admin accounts on a system, horizontal privilege propagation would mean one admin acquiring the privileges of another.
03

Explaining Vertical Privilege Propagation

On the other hand, vertical privilege propagation refers to acquiring permissions or privileges from a level higher than the current one. This can happen in cases such as when a standard user account acquires the rights of an admin account.
04

Outlining the Restraints

Every system has restraints or limitations to ensure security. For horizontal propagation, the limit is the level of privileges a user can transfer to another on the same level and is imposed to prevent unauthorized access. For vertical propagation, these restraints exist to prevent a lower level user from gaining higher level privileges without proper authorization.
