China, 2-4, April. 2010, pp.238-241 Research and Application of Enterprise Search Based on Database Security Services Yi Huang 1 , Xinqiang Ma 1 , and Danning Li 2 1 School of Computer Sciences, Chongqing University of Arts and Sciences, Chongqing, P.R China Email: huangyicq@sohu.com, mxq345@sohu.com 2 Guizhou <strong>Academy</strong> of Science, Guiyang, P.R China Email: lidn121@hotmail.com Abstract—With the development of internet and the build of enterprise information, How to organize the information and make it accessible and useful Especially, how to support the information security services They have been become a hot topic of internet and enterprise information. This paper discussed the enterprise search systems based on database security services. Such as Oracle Ultra Search, Sybase Enterprise Portal and LogicSQL-based enterprise archive and search system. Ultra Search enables a portal search across the content assets of a corporation, bringing to bear Oracle’s core capabilities of platform scalability and reliability. “Sybase Enterprise Portal Security Services”, which describes how Enterprise Portal security works, a description of the security APIs that you customize to accommodate your Enterprise Portal system, and a description of the Web-based Security Administration tool. LogicSQL is independently developed based on the Linux high-level security database system. The development of enterprise internal Search System is based on LogicSQL security database. The enterprise information resources integration and security search are completed in the search system. Index Terms—security services, enterprise search, Internet search, database security, Network security I. INTRODUCTION In the age of the Internet, proliferation of information is causing a new information management crisis for enterprises. Using the World Wide Web, workers become their own information retrieval experts. But searching for the right answers can be more than frustrating: Information is ultimately stored in corporate databases, Web pages, files in various popular document formats and in email or groupware systems. Servers are located throughout the country and across the globe. Corporate information is distributed across enterprises in both structured and unstructured form - structured relational databases, unstructured Word-processing documents, spreadsheets, presentations. As applications demand transactional consistency, coordinated multi-user access, administration and maintenance for content, a natural gradient is created to move more and more corporate information into databases. However, even when multiple databases are involved, searching across databases needs a robust solution. Corresponding author: Xinqiang Ma and Danning Li Many businesses manage both distributed computing environments and disparate data sources. They must gather information, integrate it into the business process, and distribute it to users with different needs. Ultra Search enables a portal search across the content assets of a corporation, bringing to bear Oracle’s core capabilities of platform scalability and reliability [1]. The Sybase Enterprise Portal solves the complex problems of providing prompt, secure, personalized, and integrated information to employees, customers, and partners [2]. The enterprise information search management tools based on LogicSQL security database is consistent with the security functions of database [3]. II. INTERNET AND ENTERPRISE SEARCHES How to organize the information and make it accessible and useful Especially, how to provide the information security services There are two mainly searching methods in this information technology times. They are Internet and Enterprise Searches. A. Internet Search If you're trying to find a particular page on the Internet, you can use one of the many available online Search Engines. These search engines allow you to search for information in many different ways -- some engines search titles or headers of documents on the net, others search the documents themselves, still others just search other indexes or directories [4]. Internet search sites can search enormous databases of Web pages, using titles, keywords or text. You can maximize the potential of search engines by learning how they work, and how to use them safely, quickly and effectively. Internet search engines are categorized by topic in our searchable directory of general and specialty search engines. Also listed are resources and tools for exploring the deep web, performing advanced research, and for learning about using search engine tools and technology [5]. B. Enterprise search Enterprise search is the practice of making content from multiple enterprise-type sources, such as databases and intranets, searchable to a defined audience [6]. The term "enterprise search" is used to describe the application of search technology to information within an organization (though the search function and its results may still be public). This is in contrast to the other two © 2010 ACADEMY PUBLISHER AP-PROC-CS-10CN006 238
main types of horizontal search environment: web search and desktop search (though the areas overlap, and systems may address these scenarios as well). The major challenge faced by Enterprise search is the need to index data and documents from a variety of sources such as: file systems, intranets, document management systems, e-mail, and databases and then present a consolidated list of relevance ranked resources from these various sources. In addition, many applications require the integration of structured data as part of the search criteria and when presenting results back to the users. And of course access controls are vital if users are to be restricted to data and documents which they are granted access by the various document repositories within the enterprise. These major challenges are unique to enterprise search. C. Internet versus enterprise search The internet and enterprise domains differ fundamentally, such as contents, user behavior and economic motivations. • The notion of a "good" answer: Internet search is vaguely defined Relevant and Popular. Enterprise search is “right” answered Specific documents. • Social forces behind the creation of Internet and intranet contents: Internet is created for attracting and holding the attention of any specific group of users, and the collective voice of many authors who are free to publish content. Intranet is created for disseminating information. There is no incentive for content creation, and all users may not have permission to publish content. • Security and copy rights: Internet includes public domain, and the user has copy rights. Enterprise: access privileges, and usually, the corporation has the copy rights. • Deployment environments: Internet is controlled by one organization as a service. Enterprise: licensed to and deployed by a variety of organizations in diverse environments. III. SECURITY REQUIREMENTS AND INFRASTRUCTURE OF TWO SEARCHES On the public World Wide Web, there's not much of a connection between security and search. You may have logins for certain web sites, and you may use https when buying something with your credit card, but that doesn't have much to do with a general search that you might do on Google or Yahoo. Yes, a few subscription sites limit what non-subscribers can see, or may require an account to read the full text of a document [7]. Enterprise security can be heavily tied to search. In larger organizations, your company login may be used to restrict which documents you can see in the search results list. Access control, usually in the form of an Access control list (ACL), is often required to restrict access to documents based on individual user identities. There are many types of access control mechanisms for different content sources making this a complex task to address comprehensively in an enterprise search environment. Generally speaking, the security infrastructure and protocols tend to be different between the public web and the enterprise; and when security is needed in search, the search engine must integrate with the available security infrastructure and protocols. The Internet and Intranet both use SSL and HTTPS. But on private networks, Single Sign On (SSO), LDAP and Active Directory are still the norm. A search application that cares about security will likely be using those protocols. A few enterprise apps still use the older "application level security"; search engine applications can do likewise. We haven't seen the distributed identity assurance model taking root in corporations yet, they still seem to prefer a tightly controlled central resource. One exception to this apathy is between different government agencies; they are starting to realize that government employees frequently need data from other agencies, and that distributed, cooperative security systems make this much more efficient, so that government employees don't have to keep creating new logins for every agency they visit. IV. CHARACTERIZING ENTERPRISE SEARCH The total is well known that there are various characteristics of the enterprises information. Such as text content in electronic form, diversity of content sources and formats, source access, structured and semistructured search, federated search, content management, people and behaviors. Beyond the difference in the kinds of materials being indexed, enterprise search systems also typically include functionality that is not associated with the mainstream web search engines [6]. These include: • Adapters to index content from a variety of repositories, such as databases and content management systems. • Federated search, which consists of (1) transforming a query and broadcasting it to a group of disparate databases or external content sources with the appropriate syntax, (2) merging the results collected from the databases, (3) presenting them in a succinct and unified format with minimal duplication, and (4) providing a means, performed either automatically or by the portal user, to sort the merged result set. • Enterprise bookmarking, collaborative tagging systems for capturing knowledge about structured and semi-structured enterprise data. • Entity extraction that seeks to locate and classify elements in text into predefined categories such as the names of persons, organizations, locations, expressions of times, quantities, monetary values, percentages, etc. • Faceted search, a technique for accessing a collection of information represented using a faceted classification, allowing users to explore by filtering available information. • Access control, usually in the form of an Access control list (ACL), is often required to restrict access to documents based on individual user identities. There are many types of access control mechanisms for different 239
