Becoming the Hacker

By: Adrian Pruteanu

Overview of this book

Becoming the Hacker will teach you how to approach web penetration testing with an attacker's mindset. While testing web applications for performance is common, the ever-changing threat landscape makes security testing much more difficult for the defender. There are many web application tools that claim to provide a complete survey and defense against potential threats, but they must be analyzed in line with the security needs of each web application or service. We must understand how an attacker approaches a web application and the implications of breaching its defenses. Through the first part of the book, Adrian Pruteanu walks you through commonly encountered vulnerabilities and how to take advantage of them to achieve your goal. The latter part of the book shifts gears and puts the newly learned techniques into practice, going over scenarios where the target may be a popular content management system or a containerized application and its network. Becoming the Hacker is a clear guide to web application security from an attacker's point of view, from which both sides can benefit.

Internal and external references


A document type definition (DTD) is used to the proper way to build a particular document. DTDs are referenced in XML documents by the use of a document type declaration (DOCTYPE) element. DTDs can be written out in full inside the XML document, or they can be referenced externally for the parser to download and process.

Internal DTDs can be found near the top of the XML document, in the DOCTYPE tag:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE user [
  <!ELEMENT user ANY>
  <!ENTITY company "Ellingson Mineral Company">
]>
<user>
  <name>Dade Murphy</name>
  <id>1</id>
  <email type="local">admin@localhost</email>
  <company>&company;</company>
</user>

The preceding internal DTD defines the user root element and an internal entity, company, which is defined to hold the string value "Ellingson Mineral Company". Within the document itself, the company entity can be referenced...
