Executing the plan Ethical hacking can take persistence. Hundreds, if not thousands, of tools can be used for ethical hacking — from your own words and actions to software-based vulnerability-assessment pro- grams to hardware-based network analyzers. These terms come from Western movies where the good guys wore white cowboy hats and the bad guys wore black cowboy hats. Hacking preys on weak security practices and undisclosed vulnerabilities. Rowling , Hardcover
Building the Foundation for Ethical Hacking in your office and no internal Web server running, you may not have as much to worry about as an Internet hosting provider would have. Your overall goals as an ethical hacker should be as follows: This section offers some well-known attacks but is by no means a comprehensive listing. That requires its own book: However, exploiting several vulnerabilities at the same time can take its toll. For example, a default Windows OS configuration, a weak SQL Server admin- istrator password, and a server hosted on a wireless network may not be major security concerns separately.
But exploiting all three of these vulnera- bilities at the same time can be a serious issue.
Nontechnical attacks Exploits that involve manipulating people — end users and even yourself — are the greatest vulnerability within any computer or network infrastructure. Humans are trusting by nature, which can lead to social-engineering exploits.
Social engineering is defined as the exploitation of the trusting nature of human beings to gain information for malicious purposes. I cover social engineering in depth in Chapter 5.
Other common and effective attacks against information systems are physical.
Hackers break into buildings, computer rooms, or other areas containing crit- ical information or property. Physical attacks can include dumpster diving rummaging through trash cans and dumpsters for intellectual property, passwords, network diagrams, and other information.
Introduction to Ethical Hacking 13 Network-infrastructure attacks Hacker attacks against network infrastructures can be easy, because many networks can be reached from anywhere in the world via the Internet.
Here are some examples of network-infrastructure attacks: OSs comprise a large portion of hacker attacks simply because every computer has one and so many well-known exploits can be used against them. But hackers prefer attacking operating systems like Windows and Linux because they are widely used and better known for their vulnerabilities.
Here are some examples of attacks on operating systems: Programs such as e-mail server software and Web applications often are beaten down: Malware clogs networks and takes down systems. And it can carry malware. Ethical hacking helps reveal such attacks against your computer systems.
Parts II through V of this book cover these attacks in detail, along with spe- cific countermeasures you can implement against attacks on your systems. Obeying the Ethical Hacking Commandments Every ethical hacker must abide by a few basic commandments. If not, bad things can happen. Working ethically The word ethical in this context can be defined as working with high profes- sional morals and principles. No hidden agendas are allowed!
Trustworthiness is the ultimate tenet. The misuse of information is absolutely forbidden. Respecting privacy Treat the information you gather with the utmost respect. All information you obtain during your testing — from Web-application log files to clear-text passwords — must be kept private. Introduction to Ethical Hacking 15 Involve others in your process.
The main reason for this is poor planning. These testers have not read the documentation or misunderstand the usage and power of the security tools and techniques. You can easily create DoS conditions on your systems when testing.
Running too many tests too quickly on a system causes many system lockups. Many security-assessment tools can control how many tests are performed on a system at the same time.
These tools are especially handy if you need to run the tests on production systems during regular business hours. You can even create an account or system lockout condition by social engi- neering someone into changing a password, not realizing that doing so might create a system lockout condition.
The Ethical Hacking Process Like practically any IT or security project, ethical hacking needs to be planned in advance. Strategic and tactical issues in the ethical hacking process should be determined and agreed upon. Planning is important for any amount of testing — from a simple password-cracking test to an all-out penetration test on a Web application.
Formulating your plan Approval for ethical hacking is essential. Obtaining sponsorship of the project is the first step. You need someone to back you up and sign off on your plan. Otherwise, your testing may be called off unexpectedly if someone claims they never authorized you to perform the tests.
Get written approval on this sponsorship as soon as possible to ensure that none of your time or effort is wasted. One slip can crash your systems — not necessarily what anyone wants. A well-defined scope includes the following information: For instance, you can test computer passwords or attempt social- engineering attacks before drilling down into more detailed systems. It pays to have a contingency plan for your ethical hacking process in case something goes awry.
This can cause system unavailability, which can reduce system performance or employee productivity. Even worse, it could cause loss of data integrity, loss of data, and bad publicity.
Handle social-engineering and denial-of-service attacks carefully. Determining when the tests are performed is something that you must think long and hard about. Do you test during normal business hours? Involve others to make sure they approve of your timing. The best approach is an unlimited attack, wherein any type of test is possi- ble. Some exceptions to this approach are performing DoS, social- engineering, and physical-security tests.
This can lead to a false sense of security. Keep going to see what else you can discover. Introduction to Ethical Hacking 17 until the end of time or until you crash all your systems. One of your goals may be to perform the tests without being detected. Other- wise, the users may be on to you and be on their best behavior.
This will help you protect the tested systems. Most people are scared of these assessments. Know the personal and technical limitations. Many security-assessment tools generate false positives and negatives incorrectly identifying vulnerabilities. Others may miss vulnerabilities.
Many tools focus on specific tests, but no one tool can test for everything. This is why you need a set of specific tools that you can call on for the task at hand. The more tools you have, the easier your ethical hacking efforts are. A general port scanner, such as SuperScan, may not crack passwords. Building the Foundation for Ethical Hacking When selecting the right security tool for the task, ask around. Get advice from your colleagues and from other people online.
A simple Groups search on Google www. Hundreds, if not thousands, of tools can be used for ethical hacking — from your own words and actions to software-based vulnerability-assessment pro- grams to hardware-based network analyzers. The following list runs down some of my favorite commercial, freeware, and open-source security tools: Appendix A contains a more comprehensive listing of these tools for your reference. The capabilities of many security and hacking tools are often misunderstood.

About this product Synopsis A complete library of the hottest, never-before-published underground hack variations In his highly provocative books, Hack Attacks Revealed X and Hack Attacks Denied , corporate hack master John Chirillo described the tools, techniques, and primary code that hackers use to exploit network security loopholes and then shows specific methods for blocking these attacks.
However, now that so many of their standard techniques have been revealed, underground hackers and cyberpunks are again skirting the system, going beyond primary code, and resorting to using complex code variations of old techniques.
That2s where this book breaks new ground--by providing, for the first time, the most comprehensive compendium of all the complex variations of these techniques, both historical and current, that the hacking underground doesn2t want you to see.
It offers astounding details on just about every tool used by those who break into corporate networks--information that will go a long way toward helping you close any remaining security gaps. In his previous books, Hack Attacks Revealed and Hack Attacks Denied, John Chirillo showed how to fight both standard and never-before-published hacks. In this companion book, he helps readers close remaining security holes by going back to the variations of old hacks that underground hackers are still using to break into corporate networks.
