Basics of pentesting

What is penetration testing?

Permeation tests, sometimes referred to as pen tests are computer-generated cyberattacks on your system to identify exploitable weaknesses. In the area of web application security, penetration testing is often employed to enhance the effectiveness of a web application firewall (WAF).

Pen testing could include the attempt to break into various application systems (e.g. applications protocols (APIs) or backend servers and frontend servers) to discover security holes, like unclean inputs that are vulnerable to attack by code injection. learn more about  pentesting tools,

The information gathered by the penetration test could be used to tweak your WAF Security policies as well as patch vulnerabilities that are discovered.

Testing stages for penetration

The process of testing the pen can be divided into five phases.

Five stages of testing for penetration

1. Plan and research

The first stage is:

The scope and the goals of a test, as well as the systems that will be tested and the methods of testing to be employed.

Collecting information (e.g. networks, name domains, email servers) to understand the workings of a target and the potential weaknesses it could face. Learn all the basics of pentesting basics

2. Scanning

Next, you must know what the target application’s behavior will be and how it will react to various attacks.

Static analysis – Examining the code of an application to determine how it performs when running. These tools can analyze the entire code in one go.

Dynamic analysis – Examining the application’s code while it is in a running state. This is a more efficient method of scanning since it offers a real-time glimpse into the performance of an application.

3. Gaining Access

This stage makes use of web application attacks, like cross-site scripting SQL injection as well as backdoors to reveal vulnerabilities of the target. The testers then attempt to exploit these weaknesses, usually by increasing privileges, stealing data, intercepting traffic, and so on. To understand the damage they can do.

4. Maintaining access

The purpose of this phase is to determine whether the vulnerability can be exploited to create an ongoing presence on the system that is exploited that is, long enough for an attacker to gain access in-depth. The idea is to replicate advanced persistent threats that are typically present in the system for months, in order to gain access to the most sensitive data of an organization.

5. Analysis

Test results are collected into a report describing:

Certain vulnerabilities were exploited

The sensitive data was access

The length of time that the pen tester could stay in the system, undetected

The information is then analyzed by security professionals to assist to set up the WAF settings of an enterprise as well as other security solutions for applications to patch weaknesses and safeguard against attacks in the future.

Testing methods for penetration

External testing

External penetration tests focus on an organization’s assets business which is visible online, e.g., the web application and the website of the company, as well as email as well as DNS servers (DNS). The aim is to get access to and collect valuable information.

Internal testing

In an internal test, the tester who has the ability to access an app through its firewall mimics an attempt to attack from an insider who is malicious. It’s not necessarily simulated as an employee who is rogue. One common scenario to start with could be an employee whose credentials were stolen thanks to a phishing attack.

Blind testing

In a blind test, testers are only provided with the names of the company which is being targeted. Security personnel has an immediate view of the way an actual attack could occur.

Double-blind testing

In a double-blind test, security personnel does not have previous knowledge about the attack. In actual life, they don’t be able to build up their defenses prior to the threat of attack.

Testing with targeted testing

In this situation, the security and tester collaborate as they keep the other apprised of their activities. This is a great practice that can provide a security team with immediate feedback from a hacker’s viewpoint.

Testing for penetration and web-based application firewalls

Testing for penetration and WAFs are distinct and mutually advantageous security measures.

For a variety of pen-testing methods (the exception of blind and double-blind tests), the tester is most likely to make use of WAF information, like logs, to identify and exploit weaknesses.

Best Locations for Penetration Testers

While penetration testers can find career opportunities throughout the U.S., location can impact your career prospects. Some states, metro areas, and cities offer more relevant positions and higher pay than others. For example, Washington, D.C., and Arlington, Virginia, pay pen testers significantly more than the national average.

Generally, prospective penetration testers can find more cybersecurity jobs in urban areas than rural ones. Below, we discuss the best states for pen testers.

Additionally, WAF administrators can benefit from data collected during pen-testing.

  1. What is the most common type of testing for pens?
  2. A thorough method of pen testing is vital to the best risk management. This involves testing all locations in your workplace 
  3. Web applications. Examiners evaluate the efficacy of security safeguards and search for any hidden vulnerabilities or attack patterns as well as any other security holes that could result in a breach of a web-based application.
  4. Mobile apps. Server-side issues include session management, cryptographic issues such as authentication and authorization issues, as well as other typical security vulnerabilities in web services.
  5. Networks. This test identifies common serious security flaws in an external system and network.
  6. Cloud. Cloud environments are significantly different from traditional on-premises environments. In general, security responsibility is split between the business that uses the cloud and the cloud service provider. As a result, cloud pen testing needs the use of specific expertise and skills to study the many aspects of cloud computing, including APIs, configurations, databases as well as encryption, storage, and security measures.
  7. Containers. Containers that are obtained from Docker are often vulnerable and can be exploited in large numbers. A misconfiguration is another common issue with the containers themselves and their surroundings. Both of these risk factors are easily identified by expert pen-testing.
  8. Devices embedded (IoT). Embedded or Internet of Things (IoT) devices like medical devices, cars and in-home appliances, and oil rig equipment and watches have distinct software testing requirements because of their long life cycles distant locations, energy restrictions regulations, and much more. Experts conduct a thorough communications analysis and an analysis of the client/server that identifies the most important issues to the particular application.
  9. Mobile devices.
