Strategies for network security

Designing better strategies against human adversaries in network security games

In a Network Security Game (NSG), security agencies must allocate limited resources to protect targets embedded in a network, such as important buildings in a city road network. A recent line of work relaxed the perfect-rationality assumption of human adversary and showed significant advantages of incorporating the bounded rationality adversary models in non-networked security domains. Given th...

Security Strategies for SCADA Networks

SCADA systems have historically been isolated from other computing resources. However, the use of TCP/IP as a carrier protocol and the trend to interconnect SCADA systems with enterprise networks introduce serious security threats. This paper describes two strategies for securing SCADA networks, both of which have been implemented in a laboratory-scale Modbus network. The first utilizes a secur...

Network Security for MANETS

A mobile ad hoc network (MANET) is a network consisting of a collection of nodes capable of communicating with each other without the help from a network infrastructure. Although security issues in mobile ad hoc networks have been a major focus in the recent years, the development of fully secure schemes for these networks has not been entirely achieved till now. MANETs have a unique characteri...

Unified Security Architecture for enterprise network security

to threats from within and outside the organization. The new openness of networked communications introduces new ethical, financial, and regulatory pressures to protect networks and enterprises from internal and external threats and attacks. Every IT security professional should be up-to-date on the Top Ten challenges to enterprise security—and the latest recommendations to address those challe...
