What Is Network Penetration Testing?

by Farhan Ali Digial Marketing


Penetration testing is a computer technology assessment technique used to pinpoint and isolate the penetration point of a network or computer system. Penetration testing, more colloquially called a Penettest or pentest, is an officially approved simulated cyber attack on a system, done so as to test the security of that system; this isn't to be mistaken with a vulnerability assessment. In a Penetration Test, a tester will try to gain access to a system without necessarily exposing its vulnerabilities - that is, he will try to determine whether or not the system is sufficiently protected from attacks. This is done by trying various simulated attacks, either successful or not, and comparing the results with the system's specifications and level of protection.

Penetration Testing can take a number of forms, depending on what kind of system it is. One form is conducted for "red teams" or red-box testers; these are computer security experts who simulate attacks in order to gather information about a system's protective mechanism. The red team's aim is to discover the flaws in a computer system by planting fake data or performing certain actions that might expose sensitive data. Sometimes, Penetration Testing is done for developers or program testers, who perform automated tests to identify issues in new software releases. Another form of Penetration Testing is done by penetration testers (also known as white-box testers), who carry out automated, black-box tests of a program or a web server, without any knowledge of the program they are testing. The focus of a Penetration Test is typically to find the weakest points in a system's design, functionality, or security.

With the rapid evolution of technology and the increased threat of online security breaches, computer security professionals have developed several techniques for performing in-depth Penetration Testing. Most modern-day pen testing is carried out with the assistance of several computer security software packages, which perform a multitude of tasks. Pen testers usually use tools such as "pen testers", "pen testing labs", "remote attackers labs", or "reverse engineering tools". These tools collect and analyze the information that the pen testers collect from the attacks. After this data is collected, computer security professionals may then manually investigate the selected vulnerability using various techniques. Some software suites provide a "black box" mode which allows the user to run the penetration testing without being able to edit or understand the program being tested.

Another popular Penetration Testing technique is fuzzing. Fuzzing is executed during Penetration Testing to test the security measures of a particular application. A tester uses a collection of validating scripts to make his/her queries more specific and to extract sensitive information from the program. While fuzzing may sound easy, implementing these scripts can be quite difficult, requiring considerable programming time and effort on behalf of the tester. However, these rigorous techniques can help secure the applications much faster.

Another popular technique used in Penetration Testing is Code injection. With the aid of a code viewer, an attacker can view the source code of a vulnerable application in order to gain access to user accounts and gain control over it. The tester will then be able to determine whether the information obtained can be effectively implemented within the application in question. For instance, a hacker may want to test the FTP application by trying to guess the login information and passing the application several times without getting any successful matches.

Many people don't really pay attention to Pen Testing because they assume that such examinations are rather challenging. However, while performing Pen Testing, computer security professionals can discover security vulnerabilities that hackers can exploit and cause serious damage to an organization's data or operations. In some cases, hackers will use a Penetration Testing session in order to locate weak points or weak spots inside an enterprise and then attack these points with malicious programs. For instance, if there are websites that do not update their content regularly, hackers could use such information to send spam emails to their subscribers and gain access to their personal e-mail accounts. While performing such a Pen Test, computer security professionals will make use of various tools such as payload testing, network traffic analysis, and many others to detect vulnerabilities on the systems of a corporate organization.

Pen Testing can also be performed against worms, Trojans, and viruses. These types of security vulnerabilities can affect any type of computer program, even web servers, and hence, it is necessary for security professionals to perform such tests on a regular basis. Moreover, worms and viruses often spread rapidly on the Internet, thereby exposing organizations to major Internet threats such as hacking. On a more personal level, hackers can exploit computer vulnerabilities by stealing confidential corporate information. Pen Testing can help corporations identify vulnerabilities on network systems before they become a serious issue. It can also help prevent such issues from becoming a disaster.

In addition to performing Penetration Testing on systems that have already been compromised, a corporate firewall is required to prevent further attacks. One way of testing the effectiveness of such a firewall is to expose it to malicious attacks using open ports. A Penetration Test performed against an open port can reveal the port's weakness, allowing the user to exploit it for malicious purposes. A Penetration Test performed on in-network firewalls can prevent a corporate organization from being vulnerable to remote attacks that could deny access to internal data or compromise the safety of network services.
