Penetration Testing Services: Comprehensive Guide 2025

[email protected] / June 13, 2024

Penetration testing services or pentesting is a security practice where cybersecurity experts try to find and exploit vulnerabilities present in applications, networks, and other digital systems. The pen testers, a.k.a ethical hackers, simulate real attacks on the target environment to identify security flaws in its defenses that attackers could take advantage of. Imagine a bank hiring a thief to break into their vault. If the thief succeeds, the bank will know where they lack in security and take active steps to fix it. Similarly, in penetration testing services, organizations hire a third-party cybersecurity firm to hack into their applications. The testers try different ways to breach the security defenses. They document the pathways through which they were able to bypass the security. Then they share the test results with the organization so that they can promptly address their security weaknesses. Since there are roughly 2,200 cyberattacks every day, organizations need to prioritize penetration testing if they want to keep their valuable digital assets safe. Therefore, this blog is going to dive into the fundamentals of penetration testing and its various aspects. If you have software applications or use networks and the cloud, you should know the importance of penetration testing services and why they are a must in this digital age. Benefits of Penetration Testing Services As per IBM, the average cost of a data breach is around $4.45 million. If this isn’t the reason for you to conduct penetration testing, here are several compelling reasons: Regular penetration testing services check whether your defenses are resilient against cyberattacks. Additionally, it helps in keeping your security protocols up to date. Types of Penetration Testing This section is going to be a bit tricky, as some consider the approach pen testers take are the types of penetration testing (black, white, and grey box). While others assume the areas where penetration testing can be done are the types (applications, networks, etc.). Nevertheless, since we care more about the digital assets that can be secured through pen testing, we will consider that. Here are the 5 main types of penetration testing: 1. Network Penetration Testing Network penetration testing services help identify vulnerabilities in the organization’s network infrastructure, including systems, hosts, and devices. The pen testers use both internal and external tests to find threats in firewall configurations, SQL servers, IPS/IDS, open ports, proxy servers, domain name systems (DNS), etc. that could allow attackers to breach the network systems. Commonly network vulnerabilities include: 2. Web Application Penetration Testing In web application penetration testing, ethical hackers try to find possible security flaws in the application that could be a possible entry point for attackers. The goal is to detect all the vulnerabilities on the server side and in the web application components, such as front and backends, APIs, and third-party services. OWASP’s top 10 web application vulnerabilities include: 3. Mobile Application Penetration Testing Since mobile apps store highly sensitive user data and handle financial transactions, they are one of the most targeted components. In fact, Over 2 million cyberattacks occurred on mobile devices globally in December 2022. In mobile application penetration testing, the testers check for possible entry points, test on all devices (Android, iOS, etc.), stay updated on the latest security patches, and use both automated and manual testing techniques. Major mobile application cyber threats include: 4. Cloud Penetration Testing Cloud penetration testing examines the security measures of cloud-specific configurations, cloud applications, passwords, encryption, APIs, databases, and storage access. Since most organizations now use cloud computing services like Microsoft Azure, Google Cloud Platform (GCP), and Amazon Web Services (AWS), regular pen tests can help organizations prevent constant security threats. Common threats in cloud computing: 5. IoT Penetration Testing IoT devices like smartwatches, voice-controlled devices, smart security devices, autonomous vehicles, etc. are all the rage, but they also have their fair share of security risks. Since these devices are interconnected through the internet and store vast amounts of user data, IoT penetration testing helps find vulnerabilities in the device configuration and network by simulating real attacks. OWASP top 10 IoT vulnerabilities: What are the Tools Used in Penetration Testing? A comprehensive penetration test uses a combination of both automated pen testing tools and manual techniques. These tools are vulnerability scanners that also generate accurate reports. However, as these tools have a limited database of vulnerabilities, they can not do in-depth analysis. Nevertheless, these tools are very effective in identifying known vulnerabilities quickly. There are several penetration tools available, but only a handful are the best, such as: 1. Burp Suite A comprehensive penetration testing tool for web applications. It includes components for scanning, crawling, and manipulating traffic, which allows testers to identify security vulnerabilities and exploit them. 2. Nmap A network scanning tool that provides detailed info about network services, hosts, and operating systems. It is a highly used open-source tool for network discovery and security audit. 3. Metasploit Metasploit is a penetration testing framework that includes a huge library of exploitable vulnerabilities. It allows pen testers to create custom exploits, simulate attacks, and automate pen testing. It is widely used to identify vulnerabilities in operating systems and applications. 4. Nessus A scanner that detects vulnerabilities in applications, loudness, and network resources. It has a vast plugin database that is compiled automatically to improve the scan performance and reduce the time required to research and remediate vulnerabilities. 5. OWASP ZAP OWASP Zed Attack Proxy (ZAP) is a web application penetration testing tool. It performs a wide range of security functions, including passive scanning, dictionary lists, crawlers, and intercepting web requests. It helps identify major vulnerabilities in web applications like SQL inject and XSS. 6. MobSF Mobile Security Framework (MobSF) is an all-in-one, automated mobile application penetration testing framework that can perform static and dynamic analysis. It helps identify vulnerabilities in all types of OS including Android and iOS. 7. Nikto It is an open-source command-line vulnerability scanner for applications that scans web servers for harmful files/CGIs, outdated software, and other security issues. It

The digital world has given a lot of scope for businesses to expand but has also opened more opportunities for cyberattacks. To prepare and mitigate such risks, penetration testing is essential in finding vulnerabilities in current security measures. Penetration testing execution standard (PTES) offers a set of guidelines that tell what should happen in a pentest. Over 75% of global companies perform penetration testing to measure their security status and compliance reasons. Another study shows that since 2001, financial losses due to cybercrimes have grown 570 times (from $2,000 to nearly $1.2 million per hour). The total loss due to cybercrimes is approximately $36.4 billion in 22 years. Penetration testing execution standard (PTES) helps companies of all sizes to properly execute effective penetration testing. In this blog, we will discuss PTES in detail, what are its sections so that you know what to expect from a penetration test. What is Penetration Testing Execution Standard (PTES)? PTES is a standardized set of rules that guides all penetration testing processes. In fact, penetration testing has been practiced for a while now, but initially, there weren’t as many rules and regulations in place guiding pen testers. Since businesses did not know what to expect from a pentest, the results were not very consistent. Ethical hacking was still considered hacking that lacked oversight and had little to no quality control. Then in 2009, a group of cybersecurity experts created the Penetration Testing Execution Standard (PTES) to address these issues. PTES is a type of penetration testing methodology that provides rules and guidelines that help businesses know what to expect from penetration testing. In addition to that, it also includes how to evaluate penetration testing and whether businesses should conduct penetration testing by themselves or hire third-party service providers. Before we dive into the details of PTES, let’s understand penetration testing and why it is important. What is Penetration Testing and Why is it Required? Penetration testing or pentesting is a security testing measure where a cybersecurity professional attempts to find and exploit vulnerabilities in a digital infrastructure. They simulate a real-world attack on the system to identify weak spots in its defenses, which actual attackers or hackers could take advantage of. It is like a bank hiring someone as a thief and trying to break into their building and access their vault. If the thief succeeds and gets inside the vault, the bank will get valuable insights into their security and which areas need improvement. Penetration testing execution standard (PTES) allows these third-party testers to conduct a systematic pentesting process for a particular IT environment.

Schedule a Call Different Types of Penetration Testing Penetration testing can be performed in three different ways following the penetration testing execution standard (PTES). However, the type of penetration testing depends on the amount of information provided by the organization for the tested environment. These are: White Box Pentesting: Maximum information is given on the tested environment. Black Box Pentesting: No information is given on the tested environment. Grey Box Pentesting: Limited information is given on the tested environment. 7 Sections of Penetration Testing Execution Standard (PTES) Penetration testing execution standard (PTES) consists of seven main sections that cover all aspects of penetration testing. The purpose of PTES is to offer clear technical guidelines to help organizations understand what to expect from a penetration test and guide them throughout the process. The standard doesn’t include every single aspect or scenario that might occur during a pen test. Instead, it focuses on a basic set of rules that outline the minimum requirements for all pen tests. 1. Pre-Engagement Interactions The first section of the Penetration testing execution standard (PTES) deals with the processes involved before starting the pen test. It includes the interactions between the client or organization and the pen testing team, starting from the final negotiation till the pen testing begins. The guidelines PTES has set for this section are: Goals of the Pen Test: Both the testing team and the client establish specific goals for the pen test. The PTES suggests them to prioritize the following: The primary goal of the pen test should be security The secondary goal should be compliance and legal accountability Scope of the Analysis: After setting clear goals, the pen testing team and the client must agree on the scope and scale of the testing. Here are the elements that need to be considered: Identifying the areas to be analyzed Deciding on the quality and quantity of the test procedures Duration and time of the test Rules of Engagement: The testing team and the client should also establish clear expectations and limitations, regarding what behaviors are not allowed. This includes: Defining particular resources that are “off limits” Setting boundaries for social engineering scams Once these pre-engagement meetings are done and goals are set, then the pen testers can start the first stage of the penetration test, i.e. reconnaissance. 2. Intelligence Gathering During this phase, the pen testers gather information through sources available publicly and perform basic searches following the rules of engagement. This process, also known as open-source intelligence (OSINT), collects all the information that could be useful for the later stages of the testing process. The intelligence-gathering stage includes three levels of reconnaissance: Level 1: This is a basic level that focuses on the compliance requirement and can often be automated. It only collects the required information about a company’s required security measures. Level 2: Going beyond basic requirements, this level explores the organization’s best practices and priorities beyond compliance. Level 3: In this advanced level, the pen testers dive deep into the organization’s complexities and business relationships to discover hidden information. After gathering the
