Two experiments examined the role that depth plays in the formation of associations during contextual cuing of visual search. Current associative models make predictions about the spatial constraints placed on learning within two-dimensional procedures, but there exists very little evidence of how these predictions translate to three-dimensional space. A virtual reality procedure was used to project the stimuli in three-dimensions. Experiment 1 established a contextual cuing effect using this procedure, while Experiment 2 examined whether the relative distance between repeated distractors and the target, or the position of the distractors relative to the observer modulated contextual cuing. It was found that the contextual cuing effect was consistent across these different conditions. As a result, there was no evidence to suggest that depth information forms a significant part of the representations that form during contextual cuing. These data are therefore broadly consistent with the mechanisms of current associative models of contextual cuing.

This Application Level Firewall Protection Profile defines the minimum security requirements for firewalls used by U. S. Government organizations handling unclassified information in a low-risk environment. Firewalls may consist of one or more devices that act as part of an organization s overall security defense by isolating an organization s internal network from the Internet or other external networks. The Protection Profile defines the assumptions about the security aspects of the environment in which the firewall will be used, defines the threats security objectives of the firewall and its environment, defines the functional and assurance requirements to meet those objectives, and provides a rationale demonstrating how the requirements meet the security objectives.

This traffic-filter firewall Protection Profile defines the minimum security requirements for firewalls used by U.S Government organizations handling unclassified information in a low-risk environment. Firewalls may consist of one or more devices that act as part of an organization s overall security defense by isolating an organization s internal network from the Internet or other external networks. Firewalls pass and block information flows based on a set of screening rules defined by an authorized administrator. This Protection Profile applies to firewalls that are capable of screening network traffic at the network and transport protocol levels, authenticating the authorized administrator for actions at the firewall, and auditing security-relevant events that occur. For clarification of terms, see terminology section.

This protection profile specifies the US government's minimum Security requirements for application level, or proxy server firewalls used in sensitive, but unclassified environments. The Protection Profile defines the threats that are to be addressed by the firewall, defines implementation-independent security objectives of the firewall end its environment, defines the functional end assurance requirements, end provides the rationale for the security objectives.
