The levels of access control, the types and rigor of authentication methods and technologies, and the degree to which accounting is applied to individual activities and operations vary according to the security requirements or policies associated with specific situations and implementations.

But, these three concepts provide a firm foundation on which security controls of all kinds may rest, from relatively lax or optimistic security regimes, all the way to extremely rigorous or pessimistic security regimes.

We explore the concepts that underlie AAA further in the sections that follow. Access Control In general, access control governs each user's ability to read, execute, change, or delete information associated with a particular computer resource. In effect, access control works at two levels: first, to grant or deny the ability to interact with a resource, and second, to control what kinds of operations or activities may be performed on that resource.

Such controls are managed by an access control system.

The access control system may be integrated with the operating system, or may be part of a more general resource management and control environment. Today, there are numerous methods of access controls implemented or practiced in real-world settings.

These include the methods described in the next four sections. In such environments, all users and resources are classified and receive one or more security labels such as "Unclassified," "Secret," and "Top Secret".

When a user requests a resource, the associated security labels are examined and access is permitted only if the user's label is greater than or equal to that of the resource. For example, a user with "Top Secret" clearance is allowed access to a "Secret" document, but a user with "Secret" clearance is not granted access to "Top Secret" information. The access control system also considers whether the operation requested falls within the operations that the user is allowed to perform on the resource such as read, write, or execute.

In MAC environments, only individuals with administrative privileges can manage access controls.

MAC is the most restrictive access control regime, inherently well-suited to the highest security environments, such as those associated with national defense programs or extremely valuable private intellectual property. This model allows for much greater flexibility and drastically reduces the administrative burdens of security implementation. There are solid arguments both for and against DAC systems. In their defense, DAC grants administrative control of resources to the people responsible for their everyday use.

Theoretically, these individuals would be best suited to assess a user's "need to know.

Publisher Description

Rule-Based Access Control In general, rule-based access control systems associate explicit access controls with specific system resources, such as files or printers. In such environments, administrators typically establish access rules on a per-resource basis, and the underlying operating system or directory services employ those rules to grant or deny access to users who request access to such resources.

Access control lists ACLs are a common rule-based access control mechanism. When a user requests a resource, the operating system checks the appropriate ACL to determine whether the user or a group the user is a member of should be granted access to that resource.

Many firewalls also use rule-based access controls to control access to a network. Reply Processing your reply Sort by: Oldest Newest Sorting replies Sorry for the possible dumb question but, where are the winners announced?
