Certified Ethical Hacker

NEW!
Mac mini when you purchase a CEH Bootcamp*
Our expert instructor will teach you to custom tune your new Mac mini for security auditing and penetration testing.

Learn to build security tools from source code to perform auditing
Master installation and configuration of security tools
Keep your new Mac Mini with all the configurations to use at home or work

COURSE DESCRIPTION
This five-day class will immerse the student into an interactive environment where they will be shown how to scan, test, hack and secure their own systems. The lab intensive environment gives each student in-depth knowledge and practical experience with the current essential security systems. Students will begin by understanding how perimeter defenses work and then be lead into scanning and attacking their own networks, no real network is harmed. Students then learn how intruders escalate privileges and what steps can be taken to secure a system. Students will also learn about Intrusion Detection, Policy Creation, Social Engineering, DDoS Attacks, Buffer Overflows and Virus Creation.

INSTRUCTOR COMMENTS

” Every power struggle consists of offensive and defensive strategies; this course goes behind the scenes of the offensive world and exposes their tricks and techniques. As we progress through the class, students get the opportunity to see the mechanics behind today’s attacks; then, armed with this new understanding, they will be prepared to detect and protect against them in the future. After completing this course, students will return to work with a clear understanding of how the other side thinks and how to tell if a compromise exists that is currently undetected.

What makes the Boson CEH different from the competitors is the blend of real world experience, passion for hacking, and custom written labs. Our labs are vastly superior to anything else you will find on the market. On the first day of class you will receive an Apple Mac mini, which we will spend the next five days building into a dedicated penetration testing platform. With this deceivingly innocent looking Mac mini, you will exploit remote servers, hijack authentication, plant rootkits, crack password files, and more! You will walk through a hack from beginning to end as opposed to simply running tools without rhyme or reason. When you leave class on Friday you take home not only the skills, but also the tools which you have built from source code, and learned to use in class. You can put your new skills to use the day you get back! ”

more individuals feel that they are a part of something larger than life

Answer: B

Clive is conducting a pen-test and has just port scanned a system on the network. He has
identified the operating system as Linux and been able to elicit responses from ports 23, 25 and
53. He infers port 23 as running Telnet service, port 25 as running SMTP service and port 53 as
running DNS service. The client confirms these findings and attests to the current availability of
the services. When he tries to telnet to port 23 or 25, he gets a blank screen in response. On
typing other commands, he sees only blank spaces or underscores symbols on the screen. What
are you most likely to infer from this?

A. The services are protected by TCP wrappers
B. There is a honeypot running on the scanned machine
C. An attacker has replaced the services with trojaned ones
D. This indicates that the telnet and SMTP server have crashed

Answer: A

By applying these techniques, security professionals can find holes in their company’s security systems before hackers do. This allows them to patch these holes and prevent customers’ personal information – including credit card and social security numbers – from being stolen.

Certified Ethical Hackers can be the ultimate “good guys.” They are separated from “bad guy” hackers who use the same techniques, because Certified Ethical Hackers are accredited professionals who only work with permission and on contract. The security flaws they find and report can save companies from millions of dollars worth of harm.

CBT Nuggets CEO and Founder, Dan Charbonneau, explained, “When I was reviewing this training, it scared me. The techniques you use as an Ethical Hacker would be dangerous in the wrong hands. That’s why it’s so important for legitimate security professionals to have this training – to protect yourself and to prevent your company from being exploited.”

CBT Nuggets covers the concepts in a series of short, 20-30 minute video segments or “nuggets,” so that the material learned can quickly be put to use on the job.

Sample videos from the Certified Ethical Hacker Series and from other CBT Nuggets training are available for viewing on the CBT Nuggets website, providing examples of the quality of instruction and format of the training.

CBT Nuggets, Inc. provides comprehensive training for certification exams from Microsoft®, CompTIA®, Cisco® and Citrix®, plus many other professional certification vendors. The training is designed to offer technical accuracy in conjunction with real-world analogies to promote understanding for beginners and experts alike.

CBT Nuggets, Inc. is the leader in video-based IT certification training. Based in Eugene, Oregon, the company was founded in 1999 and is committed to providing quality educational training videos to the information technology industry. For more information, visit www.cbtnuggets.com.

Ethical Hacker Certification Information [eccouncil.org]

Exam update: This series maps to the CEHv5 version of the Certified Ethical Hacker exam objectives. This exam will continue to be available through June 3rd, 2009, and if you are studying for this exam, this training will continue to be an invaluable resource.

EC-Council has released new, CEHv6 objectives for Certified Ethical Hacker certification. A new exam based on these objectives will launch November 5th, 2008. Watch the CBT Nuggets videos in development page for updates on upcoming CBT Nuggets training for this exam.

You’re up late, banging away at your keyboard. You find the hole you were looking for. Now you just find the right directory, copy a couple files, back right out of the system, and erase your tracks. Within 15 minutes of finding a back door into the network, you’ve downloaded transaction data for all credit card transactions within the last two years. You’d think credit card processing companies would be more secure than that.

The FBI should be busting down your door any minute now. But they won’t. You print out your keystroke logger info. You make a phone call. “I got in.” They don’t believe it. But when you deliver the keystroke log the next day, they’re floored. They cut you a check, and offer you an even bigger contract to help them fix the hole.

Do things that should get you arrested – but get paid instead. Ethical Hacking is so cool.

“What makes this knowledge so valuable?”

The work you do as an Ethical Hacker can save businesses from massive harm. You get to find and close off vulnerabilities that hackers could otherwise exploit to get inside your network and steal or even destroy data. By getting there first, you prevent leaks of sensitive information – even fraud and identity theft against employees and customers.

Businesses recognize the value of security pros that are able to shut down “back-doors” into their network. Protecting their sensitive data protects their livelihood. Because the work you do as an Ethical Hacker can prevent significant harm to their business, companies will pay you top dollar to do some of the most interesting work in information security.

“What will Ethical Hacker training teach me?”

In this series you’ll learn the 5 Steps of a Hack. You’ll also learn legal considerations for working as an Ethical Hacker. You’ll learn all about passive intelligence gathering, and get suggestions for gathering critical information through social engineering.

Other things covered in the Certified Ethical Hacker Series include TCP exploits, ICMP exploits, and other network reconnaissance techniques; pulling packets out of network communications to sniff passwords, hubs, and switches; SNMP and DNS exploits; password cracking; gaining unauthorized access to a wireless network; erasing your tracks after penetrating a network; web and file exploits too dangerous to name; and much more.

“Does this training cover the Certified Ethical Hacker exam?”

The Certified Ethical Hacker Series covers more than how to exploit your network, and how to use that knowledge to keep others from doing the same thing. It also maps to the exam objectives for CEH certification from EC-Council. It’s a comprehensive resource to use for both exam prep and on-the-job reference, so you can add this valuable certification to your resume.

“Isn’t this knowledge dangerous?”

From CBT Nuggets CEO Dan Charbonneau:

“I actually had a wave of fear hit me as I was half-way through reviewing this series. ‘We can’t sell this.’ That was my gut reaction. It’s too dangerous, it teaches too much, it’s too powerful. My second thought was, ‘We need to sell this to as many people as possible’, thinking it safest if the people being attacked know exactly how to attack, and therefore how to protect.”
Prerequisites

The EC-Council (www.eccouncil.org) Certified Ethical Hacker (CEH) certifi-
cation is designed to qualify skilled information system security professionals
in performing ethical attacks against target information systems to assist an
organization in developing preemptive approaches against hackers. A CEH
understands the tools and methods used by malicious individuals against net-
works and applies his or her skills to help organizations identify vulnerabili-
ties in their systems.
The CEH Prep Guide prepares candidates for the CEH certification examina-
tion by providing in-depth coverage of the latest hacking techniques required to
pass the qualifying CEH 312-50 or ECO-350 examinations. The subject matter is
presented in a concise, professional manner in an easy-to-understand format
and includes review questions at the end of each chapter to test a candidate’s
knowledge of the material. The included CD, with many hundreds of questions
and answers, also serves as a self-paced examination review and knowledge
reinforcement tool.
In addition to technical content, the CEH Prep Guide emphasizes the legal
and ethical requirements associated with ethical hacking and the increased
professional responsibility that goes along with the CEH certification.
Because this book provides a focused presentation of the CEH material, it is
extremely valuable to professionals seeking to advance their careers, levels of
competence, and recognition in the Ethical Hacking and penetration testing
field. The knowledge gained is applicable to commercial, industrial, military,
and government organizations.
The CEH certification also makes an individual a much-desired employee to
an organization. This professional brings the knowledge of security threats, pen-
etration testing, vulnerability analysis, risk mitigation, business-related issues,

and countermeasures to an organization along with the means to upgrade an
organization’s defenses in an effective and cost-efficient manner. The CEH has
knowledge of both offensive and defense measures in order to protect an orga-
nization’s information systems.
To sit for the CEH certification examination, a candidate must either have
attended a CEH course at an EC-Council Accredited Training Center or prepare
through self-study. In the self-study path, the candidate must have at least two
years of information system security experience endorsed by his or her employer.
If the candidate does not have two years of experience but has educational expe-
rience, he or she can submit a request to EC-Council for consideration on a case-
by-case basis.
No matter which path the CEH candidate chooses, the CEH Prep Guide is a
valuable tool for acquiring the necessary knowledge to prepare for and pass
the CEH exam. The clear and detailed explanations of key ethical hacking top-
ics along with the hundreds of review questions greatly increase the candi-
date’s chances of success when taking the CEH examination.
The CEH Examination Application Form (ECO-350) can be downloaded from
the EC-Council website (www.eccouncil.org/CEH.htm) and the completed form
should be faxed to the EC-Council at +1-212-202-3500 for verification. After ver-
ification, the candidate will receive an eligibility voucher number that can be
used to register and schedule the test at any Authorized Prometric Testing Cen-
ter globally. The cost of the examination is USD 250.
EC-Council offers two examinations: Exam 312-50 and Exam ECO-350. Only
students who have undergone training at an EC-Council Accredited Training
Center are eligible to appear for the Web-based Prometric Prime Exam 312-50.
Self-study candidates are authorized to sit for the ECO-350 Exam at an Autho-
rized Prometric Testing Center. Both exams are identical in source and lead to
the CEH certification.
The examination comprises 150 questions with a four hour time period
in which to complete the exam. The exam duration is four and one half hours
for Non-English speaking countries. A score of 70 percent is required to pass
the exam.
The CEH Exam can be retaken with no restrictions or waiting period, if nec-
essary. The CEH certification is valid for 2 years and EC-Council Professional
Education Credits (EPE) are required to maintain the certification. If the can-
didate passes the examination, he or she will receive a welcome kit in eight
week’s time.
