Introduction of Penetration Testing

Penetration testing can be defined as a legal and authorized attempt to locate and successfully exploit computer systems for the purpose of making those systems more secure. The process includes probing for vulnerabilities as well as providing proof of concept attacks to demonstrate the vulnerabilities are real.

Perform Hacking

Proper penetration testing always ends with specific recommendations for addressing and fixing the issues that were discovered during the test. On the whole, this process is used to help secure computers and networks against future attacks. The general idea is to find security issues by using the same tools and techniques as an attacker. These findings can then be mitigated before a real hacker exploits them.

Penetration testing

Penetration testing is also known as :

  • Pen testing
  • PT
  • Hacking
  • Ethical hacking
  • White hat hacking
  • Offensive security
  • Red teaming.
Hacking

It is important to spend a few moments discussing the difference between penetration testing and vulnerability assessment. Many people (and vendors) in the security community incorrectly use these terms interchangeably. A vulnerability assessment is the process of reviewing services and systems for potential security issues, whereas a penetration test actually performs exploitation and Proof of Concept (PoC) attacks to prove that a security issue exists. Penetration tests go a step beyond vulnerability assessments by simulating hacker activity and delivering live payloads. In this book, we will cover the process of vulnerability assessment as one of the steps utilized to complete a penetration test,

Setting the Stage

Understanding all the various players and positions in the world of hacking and penetration testing is central to comprehending the big picture. Let us start by painting the picture with broad brush strokes. Please understand that the following is a gross oversimplification; however, it should help you see the differences between the various groups of people involved. It may help to consider the Star Wars universe where there are two sides of the “force”: Jedis and Siths. Good vs Evil. Both sides have access to an incredible power. One side uses its power to protect and serve, whereas the other side uses it for personal gain and exploitation.

Learning to hack

Learning to hack is much like learning to use the force (or so I imagine!). The more you learn, the more power you have. Eventually, you will have to decide whether you will use your power for good or bad. There is a classic poster from the Star Wars Episode I movie that depicts Anakin as a young boy. If you look closely at Anakin’s shadow in the poster, you will see it is the outline of Darth Vader. Try searching the Internet for “Anakin Darth Vader shadow” to see it. Understanding why this poster has appeal is critical. As a boy, Anakin had no aspirations of becoming Darth Vader, but it happened nonetheless.

Hacking use for Profession

It is probably safe to assume that very few people get into hacking to become a super villain. The problem is that journey to the dark side is a slippery slope. However, if you want to be great, have the respect of your peers, and be gainfully employed in the security workforce, you need to commit yourself to using your powers to protect and serve. Having a felony on your record is a one way ticket to another profession. It is true that there is currently a shortage of qualified security experts, but even so, not many employers today are willing to take a chance, especially if those crimes involve computers. The rules and restrictions become even more stringent if you want a computer job which requires a security clearance.

PT

It is important to note that ethical hackers complete many of the same activities with many of the same tools as malicious attackers. In nearly every situation, an ethical hacker should strive to act and think like a real black hat hacker. The closer the penetration test simulates a real-world attack, the more value it provides to the customer paying for the penetration testing (PT).

White and Black Hat Hackers

White hat and black hacking

The first and simplest way to differentiate between white hats and black hats is authorization. Authorization is the process of obtaining approval before conducting any tests or attacks. Once authorization is obtained, both the penetration tester and the company being audited need to agree upon the scope of the test. The scope includes specific information about the resources and systems to be included in the test. The scope explicitly defines the authorized targets for the penetration tester. It is important that both sides fully understand the authorization and scope of the PT. White hats must always respect the authorization and remain within the scope of the test. Black hats will have no such constraints on the target list.

Ethical hacker and Malicious hacker

The second way to differentiate between an ethical hacker and a malicious hacker is through examination of the attacker’s motivation. If the attacker is motivated or driven by personal gain, including profit through extortion or other devious methods of collecting money from the victim, revenge, fame, or the like, he or she should be considered a black hat. However, if the attacker is preauthorized and his or her motivation is to help the organization and improve their security, he or she can be considered a white hat. In addition, a black hat hacker may have a significant amount of time focused on attacking the organization. In most cases, a PT may last 1 week to several weeks. Based on the time allotted during the PT, a white hat may not have discovered more advanced time-intensive exposures.

Black Box Penetration Testing

Black Box Testing

Black box penetration testing, also known as “covert” testing, employs a significantly different strategy. A black box test is a much more realistic simulation of the way a skilled attacker would attempt to gain access to the target systems and network. This type of test trades thoroughness and the ability to detect multiple vulnerabilities for stealth and pin-point precision. Black box testing typically only requires the tester to locate and exploit a single vulnerability. The benefit to this type of test is that it more closely models how a real-world attack takes place. Not many attackers today will scan all 65,535 ports on a target. Doing so is loud and will almost certainly be detected by firewalls and intrusion detection systems.

Skilled Malicious Hackers

Skilled malicious hackers are much more discrete. They may only scan a single port or interrogate a single service to find a way of compromising and owning the target. Black box testing also has the advantage of allowing a company to test its incident response procedures and to determine if their defenses are capable of detecting and stopping a targeted attack.
