This paper will examine the differences between the security posture of Microsoft’s SQL Server and Oracle’s RDBMS based upon flaws reported by external security researchers and since fixed by the vendor in question. Only flaws affecting the database server software itself have been considered in compiling this data so issues that affect, for example, Oracle Application Server have not been included. The sources of information used whilst compiling the data that forms the basis of this document include:
The Microsoft Security Bulletins web page
The Oracle Security Alerts web page
The CVE website at Mitre.
The SecurityFocus.com website
A general comparison is made covering Oracle 8, 9 and 10 against SQL Server 7, 2000 and 2005. The vendors� flagship database servers are then compared.
