Weekly cyberattacks per organization reached 1,308 on average in the first quarter of 2024 – a 28% increase from the last quarter of 2023.1 One powerful tool to defend against these increasingly sophisticated threats is penetration testing. But what exactly is penetration testing, and why is it so important for your business? Let’s dive in and explore this essential cybersecurity practice.
What Is Penetration Testing?
A penetration test, often called a pen test, is a controlled simulation of a cyber attack on your business’s computer systems, networks, and applications. The goal is to find and fix vulnerabilities before malicious hackers can exploit them.
Think of it as hiring a “white hat” hacker to break into your systems. These ethical hackers use the same tools and techniques as bad actors, but with your permission and for your benefit. By mimicking the tactics and techniques of potential attackers, penetration testing gives you a realistic picture of your organization’s security strengths and weaknesses.
Common Vulnerabilities Discovered in Penetration Testing
Understanding common vulnerabilities can help you better prepare for penetration testing and subsequent fixes. Here are some issues frequently uncovered during a pen test:
- Weak Passwords: Easily guessable passwords, such as default passwords, simple combinations like “123456,” or passwords based on readily available personal information, pose a significant security risk. A 2022 report found that hacking tools can crack 96% of common passwords in less than one second.2
- Outdated Software: Unpatched software in operating systems, applications, and firmware can have known vulnerabilities that attackers can exploit.
- Misconfigured Systems: Improperly configured firewalls, access controls, or system settings can create gaps in your security posture.
- Insufficient Access Controls: Weak access controls make it easy for unauthorized users to access your sensitive data or systems. These often include broad user privileges or failure to revoke access for former employees.
- Insecure APIs: In a 2023 survey, 92% of businesses reported experiencing an API-related security incident.3 Poorly secured Application Programming Interfaces (APIs) can provide unauthorized access to data or systems.
- Social Engineering Vulnerabilities: Employees susceptible to phishing emails, pretexting, or other social engineering tactics can inadvertently compromise security.
What Are the Benefits of Penetration Testing?
Penetration testing offers several benefits that make it indispensable for any comprehensive cybersecurity strategy. Regularly performing pen testing can help your security teams:
Identify Hidden Vulnerabilities
Penetration testing uncovers security weaknesses that might be missed during regular assessments. While automated scans and routine security checks are important, they often can’t identify complex vulnerabilities that require human insight.
Penetration testers use their expertise and creativity to find hidden flaws in your systems, mimicking the techniques of real-world attackers. This process can reveal subtle vulnerabilities that might otherwise go unnoticed until exploited by a malicious actor.
Meet Compliance Requirements
Many industry regulations require regular penetration testing to ensure data protection. For example, the Payment Card Industry Data Security Standard (PCI DSS) calls for annual penetration testing for organizations that handle credit card data. By conducting penetration tests, you can demonstrate due diligence and compliance with these industry standards, potentially avoiding hefty fines and legal issues.
Protect Your Reputation
Proactively finding and fixing vulnerabilities can prevent breaches that could damage your company’s reputation. News of a security breach often spreads quickly, resulting in eroded customer trust and financial losses.
Investing in penetration testing demonstrates a commitment to security that can enhance your reputation. In the event of an attempted attack, the measures you’ve put in place as a result of penetration testing could be the difference between a minor incident and a major breach.
Provide a Reality Check
Penetration testing gives you a clear, unbiased view of your current security status. It’s easy to become complacent or overconfident about your security measures, especially if you haven’t experienced a breach.
Penetration testing serves as a wake-up call, providing concrete evidence of your security strengths and weaknesses. This reality check can be invaluable in securing buy-in from management for necessary security investments and in fostering a culture of security awareness across your organization.
Each type of penetration testing focuses on different aspects of your digital infrastructure. Understanding these can help you choose the best approach for your company’s specific needs.
Network Penetration Testing
Network penetration testing targets network infrastructure, including servers, firewalls, and routers, to help uncover weaknesses that could allow unauthorized access to your network.
Testers might attempt to exploit vulnerabilities in network protocols, misconfigured devices, or outdated software. They may also try to bypass firewalls, escalate privileges, or move laterally within the network. The goal is to identify any entry points that a bad actor could use to breach your network defenses.
Web Application Penetration Testing
Web application testing looks for issues like SQL injection, cross-site scripting (XSS), broken authentication, and other vulnerabilities that could compromise the security of your web-based apps.
Testers will scrutinize your application’s input validation, session management, and data handling processes. They may attempt to manipulate parameters, inject malicious code, or exploit logic flaws in the application. This type of testing is crucial in today’s landscape, where web applications often serve as the primary interface between businesses and their customers.
Social Engineering Penetration Testing
68% of breaches in 2023 involved a non-malicious human action,4 making social engineering pen tests essential for businesses of all sizes.
Social engineering tests assess the human element of your security infrastructure, which may involve attempts to trick your staff into revealing sensitive information or performing actions that could compromise security. Testers might use phishing emails, pretexting (creating a fabricated scenario), baiting, or even physical impersonation to test how well your staff follows security policies.
Cloud Penetration Testing
Cloud penetration testing has become increasingly important as more businesses move to the cloud. This type of testing checks for vulnerabilities in your cloud-based assets and services.
Testers might attempt to exploit misconfigurations in cloud services, weak access controls, or vulnerabilities in the cloud provider’s infrastructure. They may also test for data leakage or unauthorized access between different cloud environments.
What Is the Penetration Testing Process?
Pen testing isn’t a one-and-done deal – it’s a structured process that ensures a thorough evaluation of your systems. Here’s what it typically involves:
- Planning and Reconnaissance: The testers gather information about your systems to understand their structure and identify potential entry points.
- Scanning: Using various tools, they scan your systems for vulnerabilities like open ports, weak passwords, or outdated software.
- Gaining Access: The testers then try to exploit these vulnerabilities to access your systems.
- Maintaining Access: Once in, they try to remain undetected and maintain control over the system for an extended period.
- Analysis and Reporting: Finally, they compile their findings into a detailed report, including discovered vulnerabilities, accessed data, and recommendations for fixes.
6 Tips for Choosing the Right Penetration Testing Provider
Selecting the right penetration testing provider is a must to ensure you receive accurate and actionable results. Here are some factors to consider:
1. Experience and Expertise
Don’t hesitate to ask about your provider’s qualifications, certifications, and years of experience in penetration testing. A provider with diverse expertise can offer insights that go beyond just identifying vulnerabilities to help you understand the broader implications for your business.
