Penetration Testing
What is Penetration Testing (pen-testing)?
Penetration testing, also called pen testing or white hat / ethical hacking, is the art and science of testing a network, web application, mobile app, IoT devices, wireless networks and control systems to find critical security vulnerabilities that an malicious actor (hacker) could potentially exploit, causing harm to your business and or clients.
Penetration testing is typically performed in two major steps. 1) scanning for vulnerabilities 2) manually attempting to exploit those vulnerabilities. The overall penetration testing process involves gathering information about the target before the test (scoping), and then identifying possible vulnerabilities and proceeding with proof of exploit and attack paths. Once the actual penetration test is complete, the penetration testing company will optimize a report based on vulnerabilities, exploits and the steps to remediate the problems. The reporting level is critical in identifying weaknesses in your systems, with the knowledge of knowing how to fix them, before your company is exposed.
Other forms of penetration testing are also popular, which include:
• Mobile application penetration testing
• Client server (or legacy) application penetration testing
• Device penetration testing, (including workstations, laptops and consumer devices (eg. tablets and smartphones)
• Wireless penetration testing
• Telephony or VoIP penetration testing.
The penetration testing process typically includes: conducting research; identifying vulnerabilities; exploiting weaknesses;
reporting findings; and remediating issues.
It’s important to note that cybersecurity is a moving target, so once items have been remediated and retested, your systems still needs proactive measures (patches, updates, monitoring etc) since a penetration test and security assessments are only accurate for the point in time that test were performed. This creates an ongoing need for vulnerability scanning and penetration testing and most smart companies have some level of ongoing assessments.
The main high level objective of penetration testing is to identify potential security weaknesses that if exposed and attacked by a bad actor, would cause some form of harm and destruction to a company or client. Another form of Penetration testing is called client awareness and it can also be used to test an organization’s security policy, compliance and the company employees’ security awareness.
Penetration testers are known as ethical hackers and Pen-tests are often referred to as white hat hacking, because in a pen test, the act is (or should be) controlled and simulated and used for the purpose of helping companies achieve an overall better security posture.
Penetration Testing Goals
The overall goal of a penetration testing is to find holes and weaknesses, however companies have various projects that many times require unique or custom goals, making the one-size fit all penetration model not the best for
Goals may including highlighting weaknesses in a company’s security policies or may include source code review and more advanced industrial control systems (ICS) testing. Some penetration testing projects may have the unique goal of seeing if a penetration tester can jump from box to box or from camera to camera. Most companies seeking out penetration testing services already have robust security measures in place (or think they do) and are looking to test those systems against real world simulated attacks. The goals for every penetration test are typically defined in a document called “Penetration Testing Scope”.
Penetration Testing – Scoping
Since scoping/project details will vary based on customer expectations, i.e., number of IP addresses, systems and other factors, it is virtually impossible to provide an out of the box “one size fits all” pricing quotation. A solid pen-testing company will want to know at the very least -preliminary information and customer requirements in order to provide the most accurate quote/timeline and expectations. Be wary of a “one price fits all” pen-test as these low price solutions that fit any scenario are most likely using an automated scan and just checking off boxes.
Why Penetration Testing?
Penetration tests should be controlled. Penetration testing companies will establish an action plan and communication plan and typically report critical vulnerabilities immediately upon finding them. A penetration test (pen test) involves the use of a variety of manual and automated techniques to simulate an attack on an company’s information systems – either from malicious outsiders or from the company’s own staff.
The main reason companies perform penetration testing typically fall into a category below:
• A growing requirement for compliance and or compliance related issues (doing business with other companies and sharing critical information)
• The impact of serious security attacks on similar companies and or industries
• A reliance on 3rd party vendors or outsourced services
• Significant changes to business processes, locations, networks or devices
• To develop a greater awareness about Cyber security attacks, and to be more proactive, rather than reactive.
Penetration testing can be invaluable, but it is labor-intensive and requires great expertise to minimize the risk to targeted systems. Systems may be damaged or otherwise rendered inoperable during the course of penetration testing, even though the organization benefits in knowing how a system could be rendered inoperable by an intruder. Although experienced penetration testers can mitigate this risk, it can never be fully eliminated. Penetration testing should be performed only after careful consideration, notification, and planning”

Most companies know that critical vulnerabilities can be resolved simply by updating critical security patches. However, more often than not, many systems across multiple client sectors are found to be using obsolete operating systems and missing patches such as the MS17-010 critical security update.
A pen test, on the other hand, is a manual process. It actively seeks vulnerabilities in the system and exploits them as hackers would. Because it is a thorough process, it provides more comprehensive results. It is carried out less often than a vulnerability scan; usually once a year.
