Do you want to learn more about the most important types of penetration testing? If so, great, but first, let’s discuss the following fact. Every company knows that a hack, and even a hack attempt, is a major risk to uptime, data privacy, and business continuity. That’s why IT security professionals are concerned that they’ve tracked security threats and attacks as they’ve continuously increased since the start of the pandemic, growing by over 70%.

With these threats increasing, it’s more important than ever before that businesses prepare and protect themselves. Fortunately, penetration testing makes measuring and improving cybersecurity makes checking defenses a streamlined and repeatable process.

What is Penetration Testing? - Different Types of Penetration Testing

What is Penetration Testing?

A penetration test, or “pen test,” is a process where security professionals are directed by a company to try and penetrate its networks or servers. This “ethical hacking,” as its often called, helps the company identify weaknesses in its systems by hiring professionals to exploit them. Of course, penetration testing is completely controlled, so no sensitive data is ever lost or leaked. 

Since they mimic the techniques of a real hacker, penetration tests are extremely effective in improving a company’s defenses.

How to Conduct a Penetration Test

There are three methods used to conduct pen tests, known as the black-box test, white-box test, and gray-box test.

  • Black-Box Test: These tests simulate an external attack, so the hacker begins with very little knowledge of the company’s internal systems and how they work. A thorough black-box test could take six weeks or longer to complete.
  • White-Box Test: These tests simulate internal attacks, like those coming from an employee or a hacker who has gained access to the systems. These typically take two to three weeks to complete and seek to answer the question of how deep an attacker can get through privilege escalation.
  • Gray-Box Test: These tests lie somewhere between the prior two methods, simulating an outside attack but with partial knowledge of internal systems. The time it takes to complete a gray-box test vary depending on system complexity and the parameters the company lays out.

 

The most popular types of penetration testing typically use some combination of black-box and white-box testing. The Penetration Testing Execution Standard (PTES) lays out seven steps, which detail how a penetration tester:

  • Conducts a meeting with the company’s internal team to discuss the scope of engagement.
  • Discovers accessible systems and related services.
  • Identifies vulnerabilities that they can exploit using manual and/or automated scanning.
  • Documents and analyzes the most notable weaknesses they feel can be exploited.
  • Performs tests on the noted weaknesses to determine the degree of damage that can be done.
  • Determines the value of the compromise and tries to maintain control of it.
  • Reports findings, evidence, and recommendations to the company’s internal team. 

 

Generally, penetration tests are tailored to the needs and budget of the company. To follow is an overview of the five most popular types of penetration tests.

#1 Network Service Penetration Testing

Network penetration tests help identify aspects that could be exploited within your networks, systems, hosts, and devices. Your team should work to find these weaknesses and make note of them, ensuring they’re addressed before a real hacker has the chance to discover them. Network pen tests can reveal weaknesses that a hacker could leverage to gain system control or access to protected data. 

#2 Web Application Penetration Testing

The use of web applications continues to grow thanks to appealing company benefits, but they also pose a significant threat if not properly secured. In a web app pen test, the “hackers” will try to learn about the system they’re targeting so they can discover and exploit weaknesses. Those weaknesses could be in the application itself or in the software your company has developed to help connect to the application and its backend. 

#3 Wireless Penetration Testing

Wireless penetration testing helps a company identify wireless connections between the company’s network and employee devices, like laptops, phones, tablets, and IoT devices. This type of pen test must be conducted on site as the tester has to be within range of the wireless network. The tester’s goal is to reveal vulnerable access points and exploit them through de-authentication, capturing a 4-way handshake, or running an offline attack. 

#4 Social Engineering Penetration Testing

Employees represent the biggest security risk to companies, whether or not they have malicious intent. Worse yet, companies continue to overlook this core threat. The fact is, if your security improvements don’t focus on your employees, all efforts will prove futile. Social engineering pen tests employ a tester to persuade or fool employees. Examples of social engineering attempts include phishing, impersonation, and baiting. Using one of these methods, a hacker could get ahold of a username, password, or other helpful information.

#5 Physical Penetration Testing

Physical penetrating tests employ a tester to attempt to circumvent the physical security measures your business has taken, whether that’s a gate, camera, sensor, lock, guard, or alarm. Unfortunately, physical security is often overlooked, but if a hacker can gain entry to your server room, they can effortlessly control your network. As such, however unlikely you think a physical hack attempt would ever be, it’s essential that you address physical security alongside cyber security.
