ABSTRACTAs the use of the web grows on both intranets and the public internet, information security is becoming crucial to organizations. As the computing industry moves from the mainframe era to the client/server era to the Internet era, a substantially increasing number of points of penetration have opened up. So, it is important that database management system (DBMS) vendors provide security solution within their product lines, such as Oracle and IBM. The structure of this paper is as follows. Six main security features will be compared among Oracle and DB2. They are security evaluations, authentication, authorization and access control, encryption, LDAP and auditing. After that, a summary of features will be given. And finally, a short conclusion to wrap the paper up.1. IntroductionAs the use of the web grows on both intranets and the public internet, information security is becoming crucial to organizations [13]. The web provides a convenient, cheap, and instantaneous way of publishing data. Now that it is extremely easy to disseminate information, it is equally important to ensure that the information is only accessible to those who have the rights to use it.With many systems implementing dynamic creation of web pages from a database, corporate information security is even more vital. Previously, strict database access or specialized client software was required to view the data. Now anyone with a web browser can view data in a database that is not properly protected. Never before has information security had so many vulnerable points. As the computing industry moves from the mainframe era to the client/server era to the Internet era, a substantially increasing number of points of penetration have opened up [13]. So, it is important that database management system (DBMS) vendors provide security solution within their product lines, such as Oracle and IBM.The following sessions will compare the security features among Oracle9i Database Enterprise Edition(Oracle) and IBM DB2 Enterprise Edition (DB2).2. Security EvaluationsEvery vendor can claim that their products are secure. Are their products really that secure? The best way to claim the security of their products is to get through security evaluations which carried out by independent, licensed and accredited organization.A security evaluation is an assessment of whether or not a product or IT system meets its security claims. The team performing the evaluation use formal criteria and methods to assess the claimed security attributes and to check for vulnerabilities.The Oracle9i database builds upon 15 independent security evaluations of its server software and 9 of these evaluations have examined the security of the Oracle database. However, IBM still hasn't completed any evaluations of DB2. Table 1 [3] shows the number of security evaluations done by Oracle and IBM DB2.Table 1: Security EvaluationsSecurity Evaluations Oracle IBM DB2US TCSEC, Level B1 1 0US TCSEC, Level C2 1 0UK ITSEC,...
