How Penetration Testing Is Done?

What is penetration testing
A penetration test, also known as a pen test, is a simulated cyber attack against your computer system to check for exploitable vulnerabilities. In the context of web application security, penetration testing is commonly used to augment a web application firewall (WAF).

Pen testing can involve the attempted breaching of any number of application systems, (e.g., application protocol interfaces (APIs), frontend/backend servers) to uncover vulnerabilities, such as unsanitized inputs that are susceptible to code injection attacks.

Insights provided by the penetration test can be used to fine-tune your WAF security policies and patch detected vulnerabilities.

Penetration testing stages
The pen testing process can be broken down into five stages.

Five Stages of Penetration Testing

1. Planning and reconnaissance
The first stage involves:

Defining the scope and goals of a test, including the systems to be addressed and the testing methods to be used.
Gathering intelligence (e.g., network and domain names, mail server) to better understand how a target works and its potential vulnerabilities.
2. Scanning
The next step is to understand how the target application will respond to various intrusion attempts. This is typically done using:

Static analysis – Inspecting an application’s code to estimate the way it behaves while running. These tools can scan the entirety of the code in a single pass.
Dynamic analysis – Inspecting an application’s code in a running state. This is a more practical way of scanning, as it provides a real-time view into an application’s performance.
3. Gaining Access
This stage uses web application attacks, such as cross-site scripting, SQL injection and backdoors, to uncover a target’s vulnerabilities. Testers then try and exploit these vulnerabilities, typically by escalating privileges, stealing data, intercepting traffic, etc., to understand the damage they can cause.

4. Maintaining access
The goal of this stage is to see if the vulnerability can be used to achieve a persistent presence in the exploited system— long enough for a bad actor to gain in-depth access. The idea is to imitate advanced persistent threats, which often remain in a system for months in order to steal an organization’s most sensitive data.

5. Analysis
The results of the penetration test are then compiled into a report detailing:

Specific vulnerabilities that were exploited
Sensitive data that was accessed
The amount of time the pen tester was able to remain in the system undetected
This information is analyzed by security personnel to help configure an enterprise’s WAF settings and other application security solutions to patch vulnerabilities and protect against future attacks.

Penetration testing methods
External testing
External penetration tests target the assets of a company that are visible on the internet, e.g., the web application itself, the company website, and email and domain name servers (DNS). The goal is to gain access and extract valuable data.

Internal testing
In an internal test, a tester with access to an application behind its firewall simulates an attack by a malicious insider. This isn’t necessarily simulating a rogue employee. A common starting scenario can be an employee whose credentials were stolen due to a phishing attack.

Blind testing
In a blind test, a tester is only given the name of the enterprise that’s being targeted. This gives security personnel a real-time look into how an actual application assault would take place.

Double-blind testing
In a double blind test, security personnel have no prior knowledge of the simulated attack. As in the real world, they won’t have any time to shore up their defenses before an attempted breach.

Targeted testing
In this scenario, both the tester and security personnel work together and keep each other appraised of their movements. This is a valuable training exercise that provides a security team with real-time feedback from a hacker’s point of view.

Penetration testing, also known as pen testing, is a simulated cyber attack on a computer system, network, or web application to test its defenses and identify vulnerabilities. The goal of pen testing is to evaluate the security of a system or application and to identify any weaknesses that could be exploited by a hacker.

There are several different methods that can be used to conduct a pen test, including the following:

Black box testing: In this approach, the tester has no prior knowledge of the system and must discover as much as possible about the system through testing.

White box testing: In this approach, the tester has complete knowledge of the system and its inner workings, and can use this knowledge to more effectively identify vulnerabilities.

Grey box testing: This approach lies somewhere between black box and white box testing, with the tester having some knowledge of the system but not complete knowledge.

Pen testers use a variety of tools and techniques to conduct their tests, including network scanners, port scanners, and vulnerability scanners. They may also use manual testing methods such as trying out common username and password combinations or attempting to inject malicious code into the system.

Once the pen test is complete, the tester produces a report detailing the vulnerabilities that were found and the risks they pose. The report also includes recommendations for how to fix the vulnerabilities.

Penetration testing, also known as pen testing or ethical hacking, is the practice of simulating an attack on a computer system, network, or application to identify vulnerabilities and assess the security of the system. Here are the general steps for how penetration testing is done:

Planning and reconnaissance: This involves gathering information about the target system, such as the operating system, applications, IP addresses, and network topology.

Scanning: This step involves using tools to scan the target system for vulnerabilities, such as open ports, misconfigured services, and outdated software.

Gaining access: Once vulnerabilities have been identified, the pen tester attempts to exploit them to gain access to the system. This may involve brute-force attacks, password cracking, or social engineering.

Maintaining access: Once access has been gained, the pen tester tries to maintain access to the system to assess the level of control they can achieve.

Analysis and reporting: After the testing is complete, the results are analyzed and a report is generated that outlines the vulnerabilities found and recommendations for remediation.

Penetration testing should only be performed by qualified professionals with permission from the owner of the system being tested. The goal is to improve the security of the system, not to cause harm or damage.
