Penetration testing, also known as “pentesting,” is a simulated cyber attack against a computer system, network, or web application to test its defenses and identify vulnerabilities that an attacker could exploit.

Here are the general steps involved in a pentesting engagement:

1. Planning and scope definition: The pentester and the client define the scope of the testing, including the systems, networks, and applications to be tested, as well as any specific rules or constraints.
2. Reconnaissance: The pentester gathers information about the target systems and networks, including publicly available information, network architecture, and potential vulnerabilities.
3. Vulnerability assessment: The pentester uses tools and techniques to identify potential vulnerabilities in the target systems and networks, including software vulnerabilities, misconfigurations, and insecure practices.
4. Exploitation: The pentester attempts to exploit identified vulnerabilities to gain access to the target systems and networks.
5. Post-exploitation: If the pentester is able to gain access to the target systems and networks, they will attempt to escalate their privileges and access additional resources.
6. Reporting: The pentester prepares a report detailing their findings, including a list of identified vulnerabilities, the steps taken to exploit them, and recommendations for remediation.

It’s important to note that pentesting should only be conducted with the permission of the owner of the systems being tested, and should follow all applicable laws and regulations.

There are several approaches that a pentester can take when conducting a penetration test. The most common approaches are:

1. Black box testing: In this approach, the pentester has little or no knowledge of the target systems and networks, and must rely on publicly available information and their own skills and tools to identify and exploit vulnerabilities.
2. Gray box testing: In this approach, the pentester has some knowledge of the target systems and networks, such as IP addresses or system architecture, but does not have access to login credentials or other sensitive information.
3. White box testing: In this approach, the pentester has complete knowledge of the target systems and networks, including access to login credentials and other sensitive information. This approach is often used to test the effectiveness of an organization’s internal controls and security practices.
4. External testing: In this approach, the pentester simulates an attack from outside the organization’s network, typically from the Internet.
5. Internal testing: In this approach, the pentester simulates an attack from within the organization’s network, typically from an employee’s computer or device.
6. Targeted testing: In this approach, the pentester focuses on a specific system, network, or application, rather than attempting to compromise the entire organization.

Penetration testing in a production environment is focused on simulating an attack against a live system that is being used by end users. The goal is to identify vulnerabilities and weaknesses that could be exploited by a real-world attacker, and to assess the organization’s ability to detect and respond to an attack.

Penetration testing in a development environment is focused on identifying vulnerabilities and weaknesses in code and applications that are being developed or are in the testing phase. The goal is to identify and fix vulnerabilities before the code or application is deployed to a production environment.

There are several key differences between penetration testing in a production environment and a development environment:

1. Impact on end users: Penetration testing in a production environment has the potential to disrupt service or compromise data, while testing in a development environment generally has no impact on end users.
2. Testing scope: In a production environment, the pentester may have access to a wide range of systems and networks, while in a development environment, the scope is typically limited to the code or application being tested.
3. Remediation: In a production environment, the focus is on mitigating the impact of identified vulnerabilities and strengthening defenses to prevent future attacks, while in a development environment, the focus is on fixing the vulnerabilities before the code or application is deployed.
4. Testing tools and techniques: In a production environment, the pentester may use more advanced tools and techniques to simulate a real-world attack, while in a development environment, the focus may be on identifying vulnerabilities using static analysis or other less invasive methods.

The deliverables of a penetration test, also known as the output or results of the test, typically include:

1. Executive summary: A high-level summary of the findings, including a list of identified vulnerabilities and the potential impact of each vulnerability.
2. Detailed report: A comprehensive report that includes a description of the testing approach and methodology, a list of identified vulnerabilities, the steps taken to exploit each vulnerability, and recommendations for remediation.
3. Vulnerability list: A list of all identified vulnerabilities, including a description of each vulnerability, the potential impact, and the recommended remediation.
4. Exploit documentation: Detailed documentation of the steps taken to exploit each identified vulnerability, including any tools or techniques used.
5. Remediation plan: A plan for addressing each identified vulnerability, including prioritization of vulnerabilities based on their potential impact and recommended remediation steps.
6. Presentation: A presentation or briefing of the findings and recommendations to the client, typically including a demonstration of the exploitation of vulnerabilities.

It’s important to note that the specific deliverables may vary depending on the specific requirements of the client and the scope of the penetration test.

What is covered by general penetration testing?

A comprehensive penetration testing process is designed to rigorously evaluate the security of a website by simulating a variety of cyber attacks. This type of testing encompasses over 7,000 known web vulnerabilities, including prevalent threats such as SQL Injections and Cross-site Scripting (XSS). It meticulously examines websites for a range of potential weaknesses, from misconfigurations and unpatched software to weak passwords and exposed databases.

What is compliance testing?

Compliance testing, in the context of cybersecurity, refers to the process of evaluating and ensuring that a system, application, or organization adheres to a set of defined standards or best practices for security. Some well-known standards in this domain are the OWASP Top 10, CWE Top 25, DISA STIG, HIPAA, ISO 27001, NIST SP 800-53, and PCI DSS.

The difference between general penetration testing and compliance testing:

General penetration testing and compliance testing are both crucial in cybersecurity, but they serve different purposes and follow distinct methodologies:

1. General Penetration Testing: This is a proactive and hands-on approach where security experts simulate cyber attacks on a system, network, or web application to identify vulnerabilities. The goal is to discover security weaknesses before malicious attackers do, by exploiting them in a controlled environment. Penetration testing is broad in scope, often tailored to the specific environment being tested, and it seeks to uncover a wide range of potential security issues, not limited to any specific set of standards or guidelines.
2. Compliance Testing: In contrast, compliance testing is focused on ensuring that systems adhere to specific standards or regulatory requirements. This type of testing checks whether the system meets predefined criteria set by standards like the OWASP Top 10, SANS 25, GDPR, HIPAA, etc. Compliance testing is more about adhering to best practices and legal requirements, and it is often more structured and checklist-based compared to the exploratory nature of penetration testing.

The time required to complete a penetration testing project can vary significantly depending on a number of factors, including:

1. Size and complexity of the target systems and networks: A large, complex network with multiple systems and applications will take longer to test than a smaller, simpler network.
2. Scope of the testing: The scope of the testing, including the systems and networks to be tested and any specific rules or constraints, will impact the time required to complete the test.
3. Testing approach: The testing approach, such as black box, gray box, or white box, will also impact the time required to complete the test.
4. Experience and expertise of the pentester: An experienced pentester will typically be able to complete the test more efficiently than a less experienced tester.

In general, a pentesting engagement can take anywhere from a few days to several weeks to complete, depending on the factors listed above. It’s important to carefully plan and scope the testing to ensure that it is completed in a timely manner and meets the client’s needs and expectations.
