What is penetration testing?
Penetration testing (also called pen testing or ethical hacking) is a systematic process of probing for vulnerabilities in your networks and applications.
It is essentially a controlled form of hacking in which the ‘attackers’ act on your behalf to find and test weaknesses that criminals could exploit.
The pen testers’ report can then inform your choice of cyber security controls.
Vulnerabilities that cyber attacks could exploit might result from:
- Poor or improper configuration;
- Known and unknown hardware or software flaws; or
- Operational weaknesses in processes or technical countermeasures.
Experienced security professionals will mimic the techniques used by criminals, but without causing damage, enabling you to address the security flaws that leave your organisation vulnerable.
All of our penetration testing services can be delivered remotely.

Why is penetration testing important?
Conducting a security assessment to identify vulnerabilities in your computer systems is essential to your organisation’s security.
An automated vulnerability assessment can give you valuable information about your security status, but cannot give you a proper understanding of the security issues you face.
Only a penetration test carried out by a trained security professional can do that.
New cyber security vulnerabilities are identified – and exploited by criminals – every week.
Previously patched vulnerabilities can also be reintroduced as your infrastructure or applications change over time.
To protect yourself, you should regularly conduct security testing to:
- Identify security flaws so that you can resolve them or implement appropriate controls;
- Ensure your existing security controls are effective;
- Test new software and systems for bugs;
- Discover new bugs in existing software;
- Support your organisation’s compliance with the EU GDPR (General Data Protection Regulation) and DPA (Data Protection Act) 2018, and other relevant privacy laws or regulations;
- Enable your conformance to standards such as the PCI DSS (Payment Card Industry Data Security Standard); and
- Assure customers and other stakeholders that their data is being protected.

For cyber security to be effective, you must implement the right solutions to protect your assets from cyber threats. This means understanding where your organisation is most vulnerable.
This free paper will teach you how to keep your business secure and safe from cyber attacks through penetration testing.
Types of penetration test
Different types of penetration testing will focus on different aspects of your organisation’s logical perimeter – the boundary that separates your network from the Internet.
Infrastructure (network) penetration tests
Infrastructure vulnerabilities include insecure operating systems and network architecture, such as:
- Flaws in servers and hosts;
- Misconfigured wireless access points and firewalls; and
- Insecure network protocols (the rules that govern how devices such as modems, hubs, switches and routers communicate with each other).
Network penetration tests aim to identify and test these security flaws.
Types of infrastructure penetration test:
External infrastructure (network) penetration tests
External penetration tests identify and test security vulnerabilities that might allow attackers to gain access from outside the network.

Internal infrastructure (network) penetration tests
Internal penetration tests focus on what an attacker with inside access could achieve. An internal test will generally:
- Test from the perspective of both an authenticated and non-authenticated user to assess potential exploits;
- Assess vulnerabilities affecting systems that are accessible by authorised login IDs and that reside within the network; and
- Check for misconfigurations that could allow employees to access information and inadvertently leak it online.

Wireless network penetration tests
If you use wireless technology, such as Wi-Fi, you should also consider wireless network penetration tests.
- Identifying Wi-Fi networks, including wireless fingerprinting, information leakage and signal leakage;
- Determining encryption weaknesses, such as encryption cracking, wireless sniffing and session hijacking;
- Identifying opportunities to penetrate a network by using wireless or evading WLAN access control measures; and
- Identifying legitimate users’ identities and credentials to access otherwise private networks and services.

Web application (software) penetration tests
Web application tests focus on vulnerabilities such as coding errors or software responding to certain requests in unintended ways.
- Testing user authentication to verify that accounts cannot compromise data;
- Assessing the web applications for flaws and vulnerabilities, such as XSS (cross-site scripting) or SQL injection;
- Confirming the secure configuration of web browsers and identifying features that can cause vulnerabilities; and
- Safeguarding database server and web server security.

Social engineering penetration tests
As technical security measures improve, criminals increasingly use social engineering attacks such as phishing, pharming and BEC (business email compromise) to gain access to target systems.
So, just as you should test your organisation’s technological vulnerabilities, you should also test your staff’s susceptibility to phishing and other social engineering attacks.

No organisation is immune to cyber attacks
Cyber attacks can disrupt your business, cause reputational damage and result in hefty fines.
Watch our short video to see how penetration testing can help protect your organisation from cyber attacks.
IT Governance’s penetration testing solutions
Our CREST-accredited penetration testing services have been developed to align with your business requirements, your budget and the value you assign to the assets you intend to test.
Our level 1 penetration tests are suitable for organisations that want to identify the common exploitable weaknesses targeted by opportunistic attackers using freely available, automated attack tools.
For those with more complex objectives, or that require a more detailed exploration of complex or sensitive environments, our Technical Services team can provide additional expertise in the form of a level 2 test.
