Answer / sandeep

Again this is another open ended question. Here are some
things you could talk about: Preferring NT authentication,
using server, databse and application roles to control
access to the data, securing the physical database files
using NTFS permissions, using an unguessable SA password,
restricting physical access to the SQL Server, renaming the
Administrator account on the SQL Server computer, disabling
the Guest account, enabling auditing, using multiprotocol
encryption, setting up SSL, setting up firewalls, isolating
SQL Server from the web server etc.
Read the white paper on SQL Server security from Microsoft
website. Also check out My SQL Server security best practices

Provide an example of a shell script which logs into SQLPLUS as SYS, determines the current date, changes the date format to include minutes & seconds, issues a drop table command, displays the date again, and finally exits.
