Supersymmetric K\"allen-Lehmann representation

We find the general form of supersymmetric invariant two point functions. By imposing supersymmetric positivity we obtain the general supersymmetric K\"allen-Lehmann representation.Comment: 9 page

Firewall Management

Network connectivity can be both a blessing and a curse. On the one hand, network connectivity can enable users to share files, exchange e-mail, and pool physical resources. Yet network connectivity can also be a risky endeavor, if the connectivity grants access to would-be intruders. The Internet is a perfect case in point. Designed for a trusted environment, many contemporary exploits are based upon vulnerabilities inherent to the protocol itself. In light of this trend, many organizations are implementing firewalls to protect their internal network from the untrusted Internet.firewall, network connection, risks, vulnerabilities

V-Model Role Engineering

The paper focuses on role engineering which is an important topic in the development of access control system, particularly when considering Role Based Access Control – RBAC models. Despite the wide use of RBAC in various applications, the role engineering process is not a standardized approach. The paper aims to define a methodology and a process model for role engineeringInformation security, access control systems, role based access control systems – RBAC, engineering methodologies, security policies, access control models

KNOWLEDGE MANAGEMENT THROUGH THE LENS OF INNOVATION AND LABOUR PRODUCTIVITY IN A KNOWLEDGE BASED ECONOMY

The 21st century brings along the recognition for the necessity to understand and measure the activity of knowledge management, for which reason organizations and system organizations, together with decisional governmental factors, do their best in order to develop policies that would promote these benefits. Knowledge management (KM) implies any activity regarding the capture and the diffusion of knowledge within the organization. In our study we analyze the impacts and dimensions of KM upon the innovation and labour productivity within the organization, and how KM affects the firm�s innovative performance. A key component of knowledge management is to provide access to stored knowledge components to improve decision making and to facilitate knowledge acquisition by the user.knowledge-based economy, knowledge management, knowledge, explicit and implicit knowledge, innovation, productivity, diffusion of knowledge.
