Cyberattacks are a far more widespread threat than ever before. As cybercriminals evolve and become more advanced, businesses need to step up their game in order to keep their systems, data, and users safe. Penetration testing is one of the best ways to figure out your organization’s security posture. Often referred to as ethical hacking, it involves a set of highly skilled individuals using their skills and knowledge to find vulnerabilities in organizations’ systems before the malicious hackers can. Pentesting should be an essential part of any organization’s security measures.
Equifax and Capital One Data Breaches
The two high-profile incidents—the Equifax breach in 2017 and the Capital One breach in 2019—show how critical it is to detect overlooked vulnerabilities and how penetration testing could prevent these weaknesses from being abused.
In the Equifax breach, hackers exploited a well known Struts framework vulnerability that had not been patched allowing it to expose sensitive data of more than 147 million people in the US, UK and Canada. An early indication of this vulnerability would have been flagged by a comprehensive penetration testing program and, if Equifax had addressed the issue before exploitation, this vulnerability may never have been exploited.
Similarly, the Capital One breach, misconfigured cloud infrastructure exposed the dangers. More than 100 million credit applications, along with Social Security numbers, bank account details and more, were accessed by a hacker through a misconfigured AWS firewall. Had penetration tests been conducted on the firewall misconfiguration, it could have been found out early.
We have a common theme here: proactive penetration testing can uncover weaknesses, whether in web applications, patch management processes, or cloud configurations, before attackers can make the most of them. For businesses/organizations’ handling sensitive data, routine penetration testing is not just a precaution—it's essential for protecting data and maintaining trust.
What is the Purpose of Penetration Testing in Cybersecurity?
The purpose of penetration testing is about putting your cybersecurity to the test. By simulating real-world attacks, ethical hackers find weaknesses in your systems, networks or applications, and provide the valuable information needed to defend against such attacks.
Penetration testing helps organizations:
- Identify undetected vulnerabilities: which are present in the systems, networks and applications.
- Test defenses: Check whether firewalls, identity detection systems, and access controls work or not.
- Assess risk: Understand the potential damage of a breach and prioritize weaknesses that need attention immediately.
- Comply with regulations: Most sectors like finance, automotive, and healthcare, are required to conduct regular penetration tests to meet regulatory standards (e.g., PCI-DSS, HIPAA).
Key Penetration Testing Phases and Steps
The penetration testing process follows a series of defined penetration testing steps to ensure adequate testing:
Planning and Scoping
- Clearly define what the test aims to achieve and trace the specific areas that need addressing.
- Set rules for the test, specifying which techniques can be used and how long the testing will run.
Reconnaissance (Information Gathering)
- Passive Reconnaissance: Collect publicly available information, such as domain names, IP addresses, and employee details.
- Active Reconnaissance: Look for open ports, software vulnerabilities, and services on the target systems.
Vulnerability Analysis
- Identify possible weaknesses using automated tools and manual techniques.
- Test for security checks like SQL injection, cross-site scripting (XSS), and insecure settings.
Exploitation
- Attempt to exploit the discovered vulnerabilities and gain unauthorized access to the system as a real attacker would.
- What have your current entry defenses been, i.e. firewalls, intrusion detection systems and authentication mechanisms, and make them withstand future threats?
Post-Exploitation
- Evaluate what kind of impact a breach would have, can sensitive data be stolen and can attackers navigate the network?
- Find out how far they would be able to access the data and take note of the potential pitfalls.
Reporting
- Get to record all the findings from found vulnerabilities, exploitation methods and the impact they can have on each issue.
- Provide recommendations to reduce the risks.
Penetration Testing for Different Industries
Across industries, penetration testing is vital, and in some there is a unique challenge related to cybersecurity. Here are some examples of how penetration testing is used in different sectors:
Penetration Testing for Finance
It is no wonder the financial sector is a hot target for cyberattacks since it more or less stores sensitive financial data. Cybersecurity penetration testing for finance is conducted to protect financial systems, finance applications and platforms that carry banking transactions from undocumented exploits such as fraud, data breach and ransomware attacks. Regular penetration testing services are beneficial for banks, financial institutions and fintechs that will allow them to identify weaknesses in their systems to secure them.
Penetration Testing for Automotive Cybersecurity
As the automotive industry moves increasingly towards connected devices and software, automotive cybersecurity penetration testing has become important. Tests may cover the network security of vehicle networks, fleet infotainment, or communication protocols between a vehicle and external networks. This penetration testing guarantees the security of our vehicles from hacker attempts ranging from the other side of the spectrum and all other cyber attacks.
Penetration Testing for Web Applications
The web application penetration testing examines vulnerabilities in web applications that could be exploited by exploiting web base interfaces e.g. SQL injection, Cross Site scripting (XSS) or Cross Site Request Forgery (CSRF). This is because web applications are used by cybercriminals as icons for access to relevant data. A good penetration testing technique for web applications is to ensure that an organization’s web site or an application is protected against common exploits.
Network Penetration Testing
Network penetration testing tests an organization’s internal and external networks to find out what is vulnerable to invasion of those networks such as routers, switches, firewalls and other network components. Network configuration testing of this type is essential to find vulnerabilities in network configurations that can lead to unauthorized access, or data breaches.
Types of Penetration Testing Services
Based on organizations' needs and objectives they are trying to achieve, organizations have several options when it comes to penetration testing services:
Remote Penetration Testing
Remote test allows testers to evaluate a network or system from an external location. The motivation of this approach is to simulate an attacker outside a physical environment looking to breach an organization's security.
Firewall Penetration Test
It tests the effectiveness of a firewall. In this case, testers determine if the firewall is set correctly to allow legitimate traffic through and block attempts to get in.
Application Penetration Testing
It is used to identify vulnerabilities on a Web application, mobile application or custom software. Application is tested on simulating the attack to make sure that our application does not get affected due to threats such as input validation flaws or insecure authentication mechanisms.
Cyber Testing and Ethical Hacking Services
It includes a multitude of penetration testing services to recreate malicious attacks on any vector, web apps, networks, or mobile phones. These tests give a good indication as to a company's overall security posture.
Would you like to improve your organization’s security posture?
Benefits of Penetration Testing
- Identifies Vulnerabilities Early: Penetration testing allows you to find vulnerabilities and address them before a cybercriminal has a chance to exploit them.
- Improves Security Posture: Testing regularly will help companies continually improve their security controls and make sure their defenses are strong enough.
- Reduces Risk of Data Breaches: During penetration testing, hidden vulnerabilities are uncovered and an organization is safeguarding sensitive data and remains a head step ahead of any possible breach.
- Compliance with Industry Standards: Penetration testing is needed for many industries just to satisfy regulatory requirements, and standards such as PCI DSS, HIPAA, and GDPR.
- Enhances Incident Response: Penetration testing leads to identifying weak spots within incident detection and response processes that could enhance readiness for real world attacks.
