This chapter provides review basics and sample questions covering the topics of Enumeration (counting off or listing what services, applications, and protocols are present on each identified computer) and System Hacking (gaining access, escalating privileges, maintaining control, and covering tracks) to help you prepare for the Certified Ethical Hacker exam.

This chapter introduces Windows enumeration and system hacking. It gives you the knowledge you need to prepare for the Certified Ethical Hacker exam, and it broadens your knowledge of Windows security controls and weaknesses. However, this chapter addresses only the basic information, as it would require an entire book to cover all Windows hacking issues. If you are seriously considering a career as a penetration tester, this chapter should whet your appetite for greater knowledge.

The chapter begins by introducing enumeration and discusses what kind of information can potentially be uncovered. Enumeration is the final pre-attack phase in which you probe for usernames, system roles, account details, open shares, and weak passwords. This chapter also reviews some basics of Windows architecture. A review of Windows users and groups is discussed. The last topic is system hacking. This section discusses the tools and techniques used for gaining access to computer systems. Although many of the tools introduced are specific to Windows systems, the steps are the same no matter what the platform, as evident in Chapter 5, “Linux and Automated Assessment Tools,” when Linux is discussed.
