The relationship between program vulnerability and library calls is analyzed, and an intrusion detection method via library calls is proposed, in which the short sequences of library call are used as signature profile. In this intrusion detection method, library interposition is used to hook library calls, and with the discussion of the features of the library call sequence in detail, an algorithm based on information-theory is applied to determine the appropriate length of the library call sequence. Experiments show good performance of our method against intrusions caused by the popular program vulnerabilities.展开更多

It takes the innovative service program based on an IC2 conceptualized program at Shanghai Jiao Tong University Library(thereafter abbreviated as SJTUL) as a concrete example to elucidate the merit of such an endeavor. Specifically, this paper discusses the particular development background, overall objectives and service contents of the IC2 motivated program at SJTUL. By presenting a detailed account of some of the key measures, major achievements and also possible future directions of library service development under the guiding principles of SJTUL's IC2 program, these authors hope that its innovative library practice may serve as a reference for other academic librarians to gain some inspirations for their own parallel service innovations or refinement focused on subject-oriented library liaison service to their constituents and parent institution's curricula and research projects.展开更多

The service has realized a reader self-directed method of interlibrary loan of printed books at more than 130 university libraries within Jiangsu Province of China in the last 5 years and with a cumulative interlibrary circulation of nearly 190,000 volumes. The paper describes the framework of the clientele, structure, functions, policies, and management mechanisms of the services, and demonstrates its contribution to the improved accessibility of library materials in the region.展开更多
