Securing Enterprises with Social Network Analysis

Computer administrators defend enterprises using tools that do not scale to the size of modem

networks. As a result, malicious behavior in enterprise networks generally is W1detected, even when

attackers do not attempt to be stealthy. One way to improve this situation may be through the

application of social network analysis to the computer sectrrity problems of the enterprise. In this

project we propose to apply social networking research to two security problems: the control of

proprietary information and the analysis of log files. In the first project, we will study how to protect

proprietary information by limiting it to “communities of collaboration.” In the second, we will

examine whether interaetions between users, computers, applications, as recorded in log files, can be

modeled as social interactions where W1usual interactions correlate with security violations. This work

provide insights that will help improve CA’s data leak prevention and log analysis products.
