Section: INFORMATION SECURITY PROGRAM DEVELOPMENT

Explanation
A web server should normally be placed within a demilitarized zone (DMZ) to shield the internal network.
Database and file/print servers may contain confidential or valuable data and should always be placed on the internal network, never on a DMZ that is subject to compromise. Switches may bridge a DMZ to another network but do not technically reside within the DMZ network segment.

Web browsers have the capability of authenticating through client-based certificates; nevertheless, it is not commonly used. When using https, servers always authenticate with a certificate and, once the connection is established, confidentiality will be maintained between client and server. By default, web browsers and servers support multiple encryption algorithms and negotiate the best option upon connection.

Explanation:
SQL injection vulnerability arises when crafted or malformed user inputs are substituted directly in SQL queries, resulting into information leakage. Hardening the database listener does enhance the security of the database; however, it is unrelated to the SQL injection vulnerability. Normalization is related to the effectiveness and efficiency of the database but not to SQL injection vulnerability. SQL injections may also be observed in normalized databases. SQL injection vulnerability exploits the SQL query design, not the operating system.
