What is pentesting?
Pen testing, also known as penetration testing or ethical hacking, is the practice of testing computer systems, networks, or applications to identify vulnerabilities that could be exploited by attackers. Pen testing plays a crucial role in proactively assessing the effectiveness of security controls, validating the resilience of the system, and improving overall cybersecurity readiness.
What can it be used for?
A penetration test is performed by security professionals who attempt to exploit weaknesses in an organisation’s defences, using the same techniques and tools that a real attacker might use. The aim is to identify security flaws that could be exploited by malicious actors, and to provide recommendations for improving the security posture of the organisation.
The ultimate goal of a penetration test is to improve the security of an organisation’s systems and data by identifying vulnerabilities before they can be exploited by attackers. By doing so, organisations can reduce the risk of cyber attacks, protect their sensitive data, and maintain the trust of their customers and stakeholders.
How to do pentesting?
A proper penetration test involves a systematic approach to assess the security vulnerabilities of a system or network. The process typically consists of several stages. First, the reconnaissance phase involves gathering information about the target system, such as IP addresses and domain names, to understand its architecture and potential entry points. Next, the scanning stage involves using various tools to identify open ports, services, and potential weaknesses. Once vulnerabilities are identified, the exploitation stage begins, where testers attempt to exploit the vulnerabilities to gain unauthorised access or control. This stage aims to simulate real-world attacks and assess the system’s resilience. Following the exploitation, testers document their findings and present them to the organisation, highlighting the risks and suggesting mitigation strategies. Finally, the remediation stage involves addressing the identified vulnerabilities and implementing security measures to strengthen the system’s defences.
What are some of the most commonly used tools in pentesting?
There are a lot of different tools out there, but here we list some of the most popular and effective tools used in pen testing.
