A hybrid of node degree and k-shell index is more effective at identifying influential spreaders and has less computational overhead than either of these traditional measures. [ABSTRACT FROM AUTHOR]

As part of a defense-in-depth security solution for domain-controlled enterprise networks, a proposed self-healing system architecture is designed to increase resiliency against botnets with minimal disruption to network services. [ABSTRACT FROM AUTHOR]

This article focuses on service discovery in pervasive computing environments. Pervasive computing environments are far more dynamic and heterogeneous than enterprise environments. Enterprise network services operate within a network scope protected by firewalls and managed by system administrators. In this regard, pervasive service directory in an office environment might target an enterprise computing service, but it might also target a service that does not belong to the enterprise domain, for instance, a colleague's personal service.

The article discusses the steps involve in effective patch management. Software vendors must establish timely and practical alerts to avoid making things complicated and to prevent wasting of time. It is also important for the organization to maintain a solid relationship with key information technology (IT) vendors to facilitate the timely release and distribution of information on product security issues and patches. Other steps involve in effective patch management include downloading patches and documentation, assessing and prioritizing vulnerabilities and testing of the patches. Deploying patches and systematic audit and assessment are also important for patch management efforts.

Most organizations have an extensive set of security requirements, established for commercial firms through complex interactions of business goals, government regulations, and insurance requirements. Meeting these requirements has been time consuming and error prone, because there haven't been standardized, automated ways of performing all of the tasks and reporting on results. Another obstacle has been the lack of interoperability across security tools. To overcome these deficiencies and reduce security administration costs, the National Institute of Standards and Technology developed the Security Content Automation Protocol (SCAP).
