What is Penetration Testing in Cyber Security 2025

Chinmaya Choudhury / January 23, 2025

Penetration testing, also called pen testing, describes processes, tools, and services designed and implemented to simulate attacks and data breaches and find security vulnerabilities. You can run a pentest on a computer system, an entire network, or a web application. The primary aim of a pentest is to identify vulnerabilities that attackers can exploit. There are various ways through which the identified vulnerabilities can be discovered. You can choose either manual pen tests, executed by a team of white hat hackers, or automated penetration testing, carried out by a software solution. Curious to learn more? Let’s dive in! What are the Benefits of Penetration Testing? Ideally, software and systems were designed to avoid hazardous security vulnerabilities in the design. A pen test shows how close it came to achieving that goal. Pen testing can help an organization in these ways: Penetration Testing Process The penetration testing involves the following five fundamental stages: Penetration Testing Methods Let’s dive deeper into penetration testing methods that ethical hackers use to uncover vulnerabilities effectively. 1. External testing External penetration tests target the assets of a company that is visible on the internet, for example, the web application itself, the company website and email, as well as domain name servers (DNS). The goal is to gain access to valuable data. 2. Internal testing In an internal test, a tester who has access to the backside of an application behind its firewall simulates the attack of a malicious insider. This is not necessarily simulating a rogue employee. An ordinary starting scenario may be a worker whose ID and password were stolen because of a phishing attack. 3. Blind testing In a blind test, only the name of the enterprise that is under attack is given to the tester. This provides security personnel with a real-time view of how an actual application assault would occur. 4. Double-blind testing Security personnel do not know what kind of simulated attack will occur in a double-blind test. Just as in the real world, they would have no idea when their defenses were about to be tested before a breach attempt occurred. 5. Targeted testing In this given condition, both the penetration tester and security personnel collaborate with each other and keep one another informed of their actions. It is very useful training in which a security team gets real-time feedback from a hacker’s point of view. Penetration Testing Tools Pen testers use a variety of tools to discover vulnerabilities. Some of the most popular tools are: Penetration testing companies are using large and complex business-critical operations, as well as custom components. Some penetration tests are necessary when the software under development is to handle sensitive data or assets such as customer information, financial assets, and transaction data. Sensitive sectors like the government, medical, and financial services industries are under high regulation; they thus require strong security measures. cybersecurity Suppose the recent infiltration provides your organization with a rather unpleasant experience. In that case, pen testing will offer powerful insight into the loopholes through which the breach was made, along with suggestions on mitigating them. In addition to the detected vulnerabilities, which were perhaps not yet exploited, this is also advantageous in preventing other future attacks. Pen Test Challenges Though extremely rewarding, penetration testing comes with certain challenges: 1. Limited Pool of Experts: Trained and certified pen testers are high-demand specialists whose utilization can be challenging. 2. Constantly Evolving Threats: Cybercriminals are ever devising new ways in which to implement their campaigns, making it difficult for the pen tests to keep up. 3. Cost and Time: Conducting penetration testing typically takes time and financial resources and is a burden on small businesses. Real-World Cases of Online Penetration Testing Organizations resort to online penetration testing for large and complex business-critical operations; equally, for custom components, online penetration testing is aimed at developing software in situations involving the handling of sensitive data, extending from financial assets to customer information and transaction data. These sensitive clients include regulated industries such as government, healthcare, and financial services, and thus require state-of-the-art security measures. If there was a breach in your organization, pen testing can help you examine the weaknesses that allowed the penetration and also provide suggestions on how to rectify those. Besides, you will find other vulnerable spots that were not exploited but still need to be secured to foil any future attempts of a breach. Penetration Testing Services automated penetration testingTwo types of penetration testing services include manual penetration tests and automated penetration tests. Manual penetration is detailed, time-consuming, and mostly one of the oldest methods; it is always done by the outside contractor or security consultancy and always in agreement with the client on the scope of the testing engaged in. A certified ethical hacker, after an agreement with the contracted organization, attempts to seek internal and external weaknesses and tries to break into the organization’s computer systems within that testing scope and creates a report detailing the findings along with recommendations to fix the flaws found. In Penetration Testing as a Service (PTaaS), the modern model combining automated frameworks seeking vulnerability testing across organizations is evolving. Thus testing with PTaaS software makes ease of access to the penetration testing-and it uses newer technologies like vulnerability scanning, dynamic application security testing (DAST), and fuzzing. PTaaS operates employing a mix of algorithms and technologies to allow super testing for finding security weaknesses and attempts to exploit them-without human assistance.

Whether one is a small startup or a multinational corporation, pen

Application Penetration Testing

Application Penetration Testing: A Complete Guide in 2025

Chinmaya Choudhury / January 10, 2025

According to the “Global Risks Report 2023” of the World Economic Forum, cybersecurity will remain one of the biggest concerns in 2024, with continued risks from attacks on technology-driven resources and services, including financial systems and communication infrastructure. In 2024, malware-free activities – phishing, social engineering, and leveraging trusted relationships – accounted for 75% of detected identity attacks. Application Penetration Testing is a proactive method where you simulate attacks in your web applications to identify vulnerabilities. In this blog post, we will explore web app penetration testing, why it is crucial for your enterprise, and how enforce it effectively. What makes Application Penetration Testing Important? Application Penetration Testing is important, even if there are existing security measures. Let’s find out the following reasons: Types of Web Application Penetration Testing The various types of Web Application Penetration Testing can be differentiated on the basis of several criteria and focus aspects for web security. This process attempts to discover weaknesses that the hacker may later exploit. Below are the primary types of penetration tests, explicitly tailored specifically for web applications in 2025. 1. Black Box Testing In black box testing, the tester does now not recognize how the software works inside. This technique simulates an outside cyberattack and concentrates on identifying vulnerabilities that can be exploited from the outside without any insider facts. Black box testing is useful for comparing the application’s external defenses. 2. White Box Testing (Also Known as Clear Box Testing or Glass Box Testing) White box testing gives a complete view of the application to the tester, which includes supply code, architecture diagrams, and credentials. This kind of information allows the tester to make an in-depth analysis of the application for vulnerabilities, which may be hard to identify from the outdoor. White box testing is effective in assessing the application’s internal security and logic. 3. Gray Box Testing Gray box testing is a hybrid approach where the tester has partial knowledge of the application’s internals. This might include limited access or an overview of the architecture and protocols but not full source code access. Gray box testing balances the depth of white box testing and the realism of black box testing, offering a well-rounded security assessment. 4. Static Application Security Testing (SAST) SAST is source code analysis, bytecode, or binaries analysis without running the application. This testing technique is useful to find security flaws at the code level, thus allowing the detection of vulnerabilities as early as in the development process. 5. Dynamic Application Security Testing (DAST) DAST works by testing an application at runtime. It simulates attacks against a running application. This is effective for runtime and environment-related vulnerabilities like authentication and session management. 6. Interactive Application Security Testing (IAST) IAST will combine aspects of both SAST and DAST, that is, analyzing the application from within during runtime. The method gives deep insights into how data flows through the application and how vulnerabilities can be exploited, giving a comprehensive view of the application’s security posture. 7. API Penetration Testing Given the critical role of APIs in modern web applications, API penetration testing specifically targets the security of web APIs. It involves API testing methods, data handling, authentication mechanisms, and how APIs interact with other application components. 8. Client-side Penetration Testing This testing method uses vulnerabilities identified in client-side technologies like HTML, JavaScript, and CSS. The testing is directed at discovering vulnerabilities that might be used against the client’s browser to gain entry, for instance, XSS and CSRF. Key Phases of App Penetration Testing Application Penetration Testing is a structured process involving several phases, each of which is important to achieve accurate and comprehensive results. Let’s break down each phase: 1. Planning and Preparation It prepares the ground for a good penetration test. In the testing planning phase, the scope of the test is clearly defined, including the actual systems to be tested and by using methods towards particular objectives. This phase has built-in rules of engagement to not disallow the normal operations of the application. 2. Information gathering In this phase, the tester gathers as much information as possible about the target web application. This may include domain names, IP addresses, software versions, and public-facing APIs. The aim is to map out the application and identify potential entry points. For instance, during the test of e-commerce, this phase of the process would reveal during the testing time that its website was hosting an outdated variant of a known CMS, which makes it vulnerable to known exploits. 3. Information gathering With the above information collected, the next stage is finding out the vulnerabilities that exist within the web app. Manual testing is, however a requirement in this stage as automation alone cannot provide more sophisticated types of vulnerabilities. Common vulnerabilities: 4. Exploitation This phase involves actively exploiting the identified vulnerabilities to assess their potential impact. The aim is to determine how much damage could be done if a malicious actor were to exploit the vulnerability. 5. Post-exploitation Once a vulnerability has been exploited, the tester reviews the breach extent. The evaluation is about the possible damage caused, sustaining access, and even pivoting to other areas of the network. For example, after breaching a vulnerability in a web application, the tester may find out that he can reach the internal company network and thus breach files and systems that were supposed to be secure. 6. Reporting It should be compiled in a report. The report must detail all vulnerabilities identified, how they were exploited, and their potential impact. Most importantly, it should present actionable remediation recommendations. Best Practices for Online Application Penetration Testing To sum it all up, here are some of the best practices to consider while performing online application penetration testing. How can Qualysec App Testing help you? At Qualysec, we can provide various application penetration testing solutions that may complement web application penetration testing in several ways. Of course, penetration testing is exclusively on the identification of vulnerabilities that web applications may have but, at
