What are the different types of penetration testing?

Safeguarding your organisation’s systems and data is absolutely vital in today’s climate of increasing cyber threats. One proactive approach that should be central to your security strategy is penetration testing. But what exactly is involved? This guide explores the various types of penetration testing that could help.

What is penetration testing?

Penetration testing, often abbreviated to pen testing, utilises ethical hacking techniques to deliberately attempt to breach your defences – just as real-world attackers would. By simulating cyber attacks, you can identify vulnerabilities before malicious hackers can exploit them. 

Have you ever wondered just how secure your network truly is? Or whether someone could actually hack into your systems? Regular pen testing provides those critical insights by rigorously testing your security controls across various areas. In terms of security, this proactive approach is similar to a comprehensive audit of your IT system’s defence capabilities, identifying weaknesses before it’s too late. This allows you to gain insights into security flaws, helps in the prioritisation of remediation efforts, and supports regulatory compliance by ensuring that security measures are not only in place but are also effective.

However, penetration testing is not a one-size-fits-all approach. Depending on your specific needs and potential risk exposure, several distinct testing types should be considered. Let’s explore the primary categories.

What are the different types of penetration testing? 

Penetration testing can be segmented into several types based on the target and scope of the attack. The primary categories include network, web application, mobile application, wireless network, social engineering, and physical penetration tests. Each type addresses specific aspects of IT security and helps in pinpointing vulnerabilities within different areas of an organisation’s infrastructure.

Network penetration testing

Network penetration testing focuses on identifying exploitable vulnerabilities in your network’s infrastructure. This type of penetration testing can be internal, assessing risks from within the organisation, or external, focusing on internet-facing components like firewalls and servers. A thorough network pen test explores vulnerabilities that could allow unauthorised access or data breaches, ensuring that both perimeter and internal network defences are robust. It’s essential for organisations to regularly evaluate their network security through these tests to safeguard sensitive data and maintain compliance with industry regulations.

Web application penetration testing

Web application penetration testing scrutinises the security of your web applications by identifying potential vulnerabilities that could be attacked by hackers. This test involves examining both front-end and back-end components, looking for issues such as SQL injections, cross-site scripting, and faulty authentication processes. By simulating attacks, testers can provide insights into how an attacker could gain unauthorised access or disrupt services, helping developers understand where enhancements are needed to protect against real-world cyber threats. This testing ensures that personal data, user credentials, and business data remain secure from unauthorised access.

Mobile application penetration testing

Mobile application penetration testing focuses on identifying vulnerabilities in apps developed for devices like smartphones and tablets. This testing is particularly important due to the personal nature and sensitivity of the data often handled by mobile apps. The process includes evaluating the app’s handling of data, its interaction with mobile APIs, and the environment in which it operates. This testing aims to uncover issues like insecure data storage, improper session handling, and vulnerabilities that could lead to unauthorised data access or loss.

Mobile app penetration testing evaluates the security of mobile apps on various platforms including iOS and Android, zoning in on issues like insecure data storage, exposure to code tampering, and leakage of sensitive information.

Wireless network penetration testing

Wireless networks pose a security risk if not properly tested. Wi-Fi, Bluetooth, and radio frequency communications could allow unauthorised access if vulnerabilities exist. That’s why wireless penetration testing is critical. In these tests, experts actively attempt to exploit weaknesses like weak encryption, rogue access points, or ways to decrypt data. If they can infiltrate, so can real attackers. The goal is to reveal wireless infrastructure risks before hackers do. By simulating attacks, testers expose blind spots in wireless security controls. You receive findings to address holes – strengthening encryption, removing rogue hotspots, and shoring up weaknesses, preventing radio frequencies from providing network gateways. Wireless penetration testing is all about getting ahead of the threats and making sure your airwaves are secure. After all, you can’t protect what you can’t see. These tests bring wireless vulnerabilities into focus so you can deal with them decisively.

Social engineering penetration testing

Social engineering penetration testing tests the human element of security by attempting to manipulate individuals into breaking normal security procedures.

Even robust technical security controls can potentially be navigated if an attacker can manipulate your employees into divulging sensitive information. Social engineering pen testing ethically evaluates that human element through tactics like phishing emails, pretexting and other methods aimed at bypassing security policies. Do your staff recognise the latest social engineering red flags? This test is important as it helps identify the need for improved security training and protocols, ensuring employees are aware and vigilant about social engineering tactics used by attackers. Unlike other types which focus on technical flaws, social engineering penetration testing targets the human element of security.

Physical penetration testing

In some cases, attackers may attempt to gain physical access to facilities and assets rather than hacking remotely. Physical penetration testing assesses the effectiveness of perimeter security measures like locks, surveillance systems, and alarms. Testers may also check the effectiveness of security personnel and procedural controls. Any physical vulnerabilities could provide a pathway for equipment theft, data breaches or operational disruption. The goal is to highlight vulnerabilities in physical security that could be exploited to gain unauthorised access to secure areas, putting both physical and digital assets at risk.

Understanding the different types of penetration testing can significantly enhance your organisation’s security posture. By implementing regular and comprehensive penetration testing, you can identify and mitigate vulnerabilities before they can be exploited.
