Types of penetration testing

Penetration testing is a vital cyber security practice for assessing digital infrastructure security. Various methodologies cater to different security concerns. These include internal infrastructure, external infrastructure, web application, cloud services and mobile application testing.

Internal Penetration Testing

Internal Infrastructure Penetration Testing

Internal infrastructure penetration testing focuses on assessing the security of your network infrastructure, including routers, switches, firewalls, and other network devices. It aims to identify vulnerabilities that could be exploited from within your network.

External Infrastructure Penetration Testing

External infrastructure penetration testing is a critical cyber security exercise aimed at evaluating the security of an organisation's external-facing assets, such as firewalls and IP addresses. This test is conducted from outside the organisation's physical and network boundaries.

Web Application Penetration Testing

Web application penetration testing involves assessing the security of web applications, such as e-commerce websites, online portals, and web services. It aims to identify vulnerabilities like SQL injection, cross-site scripting (XSS), and insecure authentication mechanisms.

Cloud Service Penetration Testing

Cloud service penetration testing is a combination of internal and external infrastructure testing focused on cloud service environments. Testing can encompass Microsoft 365/Azure, Google Cloud and AWS as required. A popular alternative to this is a security configuration review.

Mobile Application Penetration Testing

Our in-house experts carry out static and dynamic analysis on mobile-hosted applications to ensure they are developed in a secure manner. Testing is conducted across multiple mobile operating systems to maintain security standards universally.

Social Engineering Penetration Testing

Social Engineering

Social engineering focuses on testing the human element of security by attempting to exploit psychological manipulation techniques. This is an effective method to gather information and establish a foothold within a target network. It assesses the effectiveness of employee training programs and security awareness.

Penetration testing process

There are 6 key steps in the penetration testing process. As a CREST-approved penetration testing provider, we provide the highest standards of of excellence and ethics at each stage of the process. We work in partnership with our clients to ensure
the process is effective, efficient and pain-free.

Social Engineering Penetration Testing

Step 1 - Planning and Pre-Engagement

The penetration tester and client establish a clear scope of the assessment, define the goals and objectives, and agree on the rules of engagement. Information will be gathered about the target system, network, or application and potential vulnerabilities and attack vectors will be identified. This phase ensures a mutual understanding of the project requirements and expectations.

Step 2 - Intelligence Gathering

The penetration tester collects specific information about the target system, such as IP addresses, domain names, and network infrastructure. The latest automated tools and techniques, such as open-source intelligence (OSINT), are commonly used to gather data from publicly available sources to complete this stage efficiently. This process helps prioritise testing efforts and focus on the most critical areas of the system.

Step 3 - Vulnerability Assessment

The penetration tester uses various scanning and enumeration tools to identify vulnerabilities in the target system. This may include port scanning, service identification, and vulnerability scanning. The vulnerabilities will then be prioritised based on their severity and potential impact. This stage allows penetration testers to define an effective approach to be employed during the exploitation phase.

Step 4 - Exploitation

Exploitation involves attempting to manipulate the identified vulnerabilities to compromise and/or gain unauthorised access within the target infrastructure/system. The penetration tester will use a combination of manual techniques or automated tools to conduct this phase in an efficient and effective manner without causing any disruption to business operations.

Web App Penetration Testing

Step 5 - Post-Exploitation

Once access to the system is gained, the penetration tester explores further to determine the extent of the compromise and assess the potential impact of the attack. Once penetration testers have attempted to pivot or escalate privileges within the network, they will remove any scripts from the compromised systems. This phase helps in understanding the severity of the vulnerabilities and their potential consequences.

Meet regulatory standards

Step 6 - Reporting

Once the testing process is complete, a detailed report is prepared, highlighting any identified vulnerabilities, exploited systems, and sensitive data accessed. It also provides recommendations on how to mitigate current vulnerabilities. Ultimately, the purpose of the final report is to help you understand your risks and take appropriate actions to improve your security posture.

Penetration Testing FAQ

How long does a penetration test take?

The duration of a penetration testing engagement varies depending on factors such as the scope of the assessment, the complexity of the system, and the availability of resources. It can range from a few days to several weeks, including pre-engagement discussions, testing, analysis, and reporting.

What will be delivered at the end of the penetration test?

You will receive a detailed report that outlines the identified vulnerabilities, their severity, and recommendations for remediation. Additionally, you may receive a debriefing session or a presentation to discuss the findings and suggested mitigation strategies. The outputs can be tailored to your specific requirements.

Will the penetration test disrupt my application's availability?

We take precautions to minimise any impact on the availability of your application during the testing process. However, there might be instances where specific tests or vulnerabilities could cause temporary disruptions. Such risks are communicated and agreed upon beforehand.

What's the difference between internal and external penetration testing?

Internal penetration testing involves testing the security measures of a company’s internal network and systems, whereas external penetration testing involves testing from an outside perspective, attempting to breach external-facing systems and gaining unauthorised access to the network. Both forms of testing are essential for mitigating security risks and identifying vulnerabilities in a comprehensive security plan.

Can penetration testing cause damage to systems?

Penetration testing is performed with the utmost care and adherence to ethical guidelines. However, there is always a slight risk of unintended consequences. Ensuring you engage with a reputable company with skilled and experienced penetration testers will ensure the necessary precautions are taken to minimise any potential damage during testing.

What qualifications do penetration testers require?

Penetration testers require a robust understanding of networking, operating systems and the different types of cyber attacks. They should possess certifications from assessment organisations such as CREST, Cyber Scheme and Offsec. These include Offensive Security Certified Professional (OSCP), CREST Registered Penetration tester (CRT) and Cyber Scheme Team Member/Leader (CSTM/CSTL).

How often should penetration testing be performed?

The frequency of penetration testing depends on various factors, including your organisation’s risk profile, industry regulations, and the rate of system changes. Generally, it is recommended to conduct penetration testing at least annually or after significant system modifications.

What are the penetration test requirements for UK Government supply chains?

UK Government supply chains, including local authorities and the NHS, mandate that all of the web applications and software they use is subject to a penetration test. These must be conducted by CHECK or CREST-Approved penetration testing providers.
