You work as the Database Administrator for www.company.com.com. All servers on the
www.company.com.com network run Windows Server 2003 and Windows Server 2000, and all client
computers run Windows XP rofessional and Windows Vista. The www.company.com.com network
area consists of a single Active Directory domain named www.company.com.com.
The www.company.com.com network contains a Microsoft SQL Server 2005 database server named
COMPANY-DB111, which you administer at a regular interval of time. COMPANY-DB111 contains and
hosts three databases that support different types of business requirements. The network uses the
DBA database that supports internal operations including maintaining data, accounting, and mailing.
The network’s regular users make use of stored procedures for the data values that need insertion
into the tables. The stored procedures used in the network of the company are designed to access

SQL variant type parameters and then use the values to build and execute ad hoc query statements
that are the part of the SQL statements. During a routine network check, you discover that there are
several odd occurrences in the database. The odd occurrences include data deleted from tables and
other unauthorized activity. You suspect a user is executing the unauthorized statements through
the stored procedures. You are required to stop the unauthorized changes while having least impact
on the stored procedures that are in use. Your explanation must use the least administrative effort.
