The document summarizes a technical presentation on network exploits and security. It discusses common network security issues like viruses, worms, and hackers. It explains how vulnerabilities can be exploited using techniques like Trojan horses, war driving, and SQL injection. The presentation then reviews security measures to protect against exploits, such as firewalls, encryption, steganography, honeypot systems, and password protection. It concludes with references to books and websites on network and computer security.

31. EXAMPLE
This SQL code is designed to pull up the records of the specified
username from its table of users:
statement = "SELECT * FROM `users` WHERE `name` = '" + userName + "';“
For example, setting the "userName" variable as:
' or '1'='1
Renders this SQL statement by the parent language:
SELECT * FROM `users` WHERE `name` = '' OR '1'='1';
True always
